[Overall configuration of straight tube LED lamp]
First, an example of the configuration of a straight tube LED lamp according to the present embodiment will be described with reference to FIG.

  FIG. 1 is a schematic perspective view showing an example of a straight tube LED lamp 1 according to Embodiment 1 of the present invention. As shown in FIG. 1, the straight tube LED lamp 1 is for power supply fixed to each of an LED module 10, a long casing 20, and an end portion in the longitudinal direction (tube axis direction) of the casing 20. A base 30 and a non-feed base 40 are provided. The straight tube LED lamp 1 is, for example, a 40-shaped straight tube LED lamp, and the total length of the lamp is about 1200 mm.

  Hereinafter, each component of the straight tube LED lamp 1 will be described in detail.

[LED module]
As shown in FIG. 1, the LED module 10 is a light source of the straight tube LED lamp 1 and is disposed in the housing 20. Here, the LED module 10 may be disposed so as to be accommodated in the housing 20, or may be disposed so that the end portion protrudes from the housing 20.

  The LED module 10 according to the present embodiment is a surface mount device (SMD) type light emitting module, and includes a substrate 11 and a plurality of LED elements 12 mounted on the substrate 11. Although not shown, the LED module 10 includes a connection terminal that receives power for causing the LED elements 12 to emit light, metal wiring that is patterned in a predetermined shape for electrically connecting the plurality of LED elements 12, and A lighting circuit for lighting the plurality of LED elements 12.

  The substrate 11 is a long substrate having a plurality of LED elements 12 arranged on the surface. Specifically, the substrate 11 is a rectangular substrate, the longitudinal direction (Y-axis direction in FIG. 1) is parallel to the longitudinal direction of the straight tubular casing 20, and the short direction (X in FIG. 1). It is arranged in the housing 20 so that the axial direction is parallel to the short direction of the housing 20. The board | substrate 11 is being fixed to the inner surface of the housing | casing 20 with the adhesive agent, for example. Alternatively, the substrate 11 may be placed on a placement surface of a heat sink (base) fixed in the housing 20. An adhesive used for bonding the substrate 11 and the housing 20 is, for example, silicone resin or cement.

  The substrate 11 has, for example, a length of 1150 to 1200 mm (longitudinal direction), a width of 5 to 25 mm (short side direction), and a thickness of 0.3 to 2.0 mm. On the main surface of the substrate 11, a lighting circuit and a plurality of LED elements 12 are arranged side by side in the longitudinal direction of the substrate 11. The substrate 11 is longer than the housing 20 in the longitudinal direction.

  Specifically, the substrate 11 is a mounting substrate for mounting the LED element 12. The substrate 11 is, for example, a resin substrate based on resin, a metal base substrate based on metal, a ceramic substrate made of ceramic, or a glass substrate made of glass.

  The resin substrate may be made of, for example, a glass epoxy substrate made of glass fiber and epoxy resin (CEM-3, FR-4, etc.), a substrate made of paper phenol or paper epoxy (FR-1 etc.), or polyimide. For example, a flexible substrate having flexibility. The metal base substrate is, for example, an aluminum alloy substrate, an iron alloy substrate, or a copper alloy substrate having an insulating film formed on the surface. In the present embodiment, a CEM-3 double-sided substrate is used as the substrate 11.

  The LED element 12 is an example of a light emitting element and is mounted on the substrate 11. In the present embodiment, the plurality of LED elements 12 are mounted so as to be arranged in a line along the longitudinal direction of the substrate 11. As shown in FIG. 1, each of the plurality of LED elements 12 is disposed apart from each other.

  The LED element 12 is a so-called SMD type light emitting element in which an LED chip and a phosphor are packaged. The LED element 12 includes a package, an LED chip disposed in the package, and a sealing member that seals the LED chip. The LED element 12 is, for example, a white LED element that emits white light.

  The package is a container formed of a white resin or the like, and includes an inverted frustoconical concave portion (cavity). The inner surface of the recess is inclined and configured to reflect light from the LED chip upward.

  The LED chip is mounted on the bottom surface of the recess of the package. The LED chip is a bare chip that emits monochromatic visible light, and is die-bonded to the bottom surface of the recess of the package by a die attach material (die bond material). The LED chip is, for example, a blue LED chip that emits blue light when energized.

  The sealing member is a phosphor-containing resin including a phosphor that is a light wavelength converter, and converts light emitted from the LED chip into a predetermined wavelength (color conversion). The sealing member protects the LED chip by sealing the LED chip. The sealing member is filled in the recess of the package, and is sealed up to the opening surface of the recess.

The sealing member includes a material selected based on the color (wavelength) of light emitted from the LED chip and the color (wavelength) of light required as a light source. For example, in order to obtain white light when the LED chip is a blue LED chip, a phosphor-containing resin obtained by dispersing YAG (yttrium, aluminum, garnet) -based yellow phosphor particles in a silicone resin is used as a sealing member. Can be used. As a result, the yellow phosphor particles are excited by the blue light of the blue LED chip to emit yellow light, so that the sealing member emits white light as a combined light of the excited yellow light and the blue light of the blue LED chip. Is released. The sealing member may contain a light diffusing material such as silica (SiO ₂ ).

  The LED element 12 configured in this way has two electrode terminals of a positive electrode and a negative electrode, and these electrode terminals and the metal wiring formed on the substrate 11 are electrically connected.

  The connection terminal (electrode terminal) is an external connection terminal that receives DC power for causing the LED element 12 to emit light from the outside of the LED module 10. The connection terminal according to the present embodiment is configured as a die, and has a resin die and a conductive portion (pin) for receiving DC power. For example, the conductive portion is connected to a lighting circuit.

  The connection terminal may be a metal electrode patterned in a rectangular shape instead of the die. For example, one end of a lead wire for supplying power to the LED element 12 is connected to a power supply pin of the power supply base 30, and the other end of the lead wire is connected to a metal electrode of the substrate 11. At this time, one end and the other end of the lead wire may each be soldered.

  The metal wiring contains a metal such as copper (Cu) and is patterned on the substrate 11 in a predetermined shape.

  The lighting circuit is an LED lighting circuit for lighting the LED element 12 mounted on the LED module 10. The lighting circuit is composed of one or a plurality of circuit elements (circuit parts).

  For example, the lighting circuit adjusts and outputs a DC voltage input via the connection terminal to a predetermined polarity for causing the LED element 12 to emit light. The DC power output from the lighting circuit is supplied to the LED element 12 of the LED module 10 via, for example, a metal wiring formed on the substrate 11.

  The circuit element is directly mounted on the substrate 11 using the substrate 11 of the LED module 10, but a circuit substrate different from the substrate 11 may be prepared and the circuit element may be mounted on the circuit substrate. . The circuit element is, for example, a rectifier circuit, a detection resistor, or a fuse element. In addition, a resistor, a capacitor, a coil, a diode, a transistor, or the like may be used as necessary.

  In order to improve the light extraction efficiency of the LED module 10, a white paint (white resist) may be applied to the surface of the substrate 11. Since the white resist has high light reflectivity, the light extraction efficiency of the LED module 10 can be improved. Further, by forming the white resist, the insulating property (breakdown voltage) of the substrate 11 can be improved, and oxidation of the metal wiring can be suppressed.

[Case]
The housing 20 is a long translucent cover having translucency that covers the LED module 10. For example, as illustrated in FIG. 1, the housing 20 is a long cylindrical body having openings at both ends. Specifically, the housing 20 is a straight tubular outer tube and is made of a transparent resin material or glass. The casing 20 is a cylinder whose cross section in the short direction (XZ cross section) is circular.

  For example, the casing 20 is a glass bulb (clear bulb) made of silica glass that is transparent to visible light. In this case, the LED module 10 disposed in the housing 20 can be viewed from the outside of the housing 20.

  Specifically, the housing 20 is a glass tube (glass bulb) containing soda-lime glass having 70 to 72% silica as a main component and having a thermal conductivity of about 1.0 W / m · K. Alternatively, the housing 20 may be a plastic tube containing a resin material such as acrylic (PMMA) or polycarbonate (PC).

  In addition, in order to diffuse the light from the LED module 10, the housing | casing 20 may have a light-diffusion function. For example, a light diffusion sheet or a light diffusion film may be formed on the inner surface or the outer surface of the housing 20. Specifically, a milky white light diffusing film can be formed by attaching a resin containing a light diffusing material (fine particles) such as silica or calcium carbonate, or a white pigment to the inner surface or the outer surface of the housing 20. it can.

  Further, the light diffusing function may be realized by a lens structure provided inside or outside the housing 20, or a concave portion or a convex portion formed on the inner surface or the outer surface of the housing 20. For example, the light diffusion function can be realized by printing a dot pattern on the inner surface or the outer surface of the housing 20 or processing a part of the housing 20. Alternatively, the light diffusing function can be realized by molding the housing 20 itself using a resin material in which a light diffusing material is dispersed.

  Thus, by providing the housing 20 with the light diffusing function, it is possible to diffuse the light emitted from the LED module 10 when the light passes through the housing 20. For example, if the SMD type LED elements 12 are arranged apart from each other as in the present embodiment, there is a possibility that a light crushing feeling (luminance variation) may occur. On the other hand, by providing the housing 20 with a light diffusing function, it is possible to suppress the feeling of being crushed.

[Feeding cap]
The power supply base 30 is an example of a first base, and is a power supply base for supplying power to the LED module 10. The feeding base 30 is fixed to one of the ends of the casing 20 or the substrate 11 in the longitudinal direction (Y-axis direction). The power supply cap 30 receives power for lighting the LED element 12 from the outside of the lamp.

  The power supply cap 30 is configured in a cap shape so as to cover one end of the casing 20 in the longitudinal direction. That is, the power supply cap 30 has a bottomed cylindrical shape, and is provided so as to cover one end of the casing 20 in the longitudinal direction. For example, the power supply cap 30 is bonded to one end of the housing 20 with an adhesive. In the present embodiment, the power supply cap 30 is a cylinder having an opening at one end and a bottom at the other.

  In addition, the adhesive agent used for adhesion | attachment with the nozzle | cap | die 30 for electric power feeding and the housing | casing 20 is a silicone resin, for example. For example, the adhesive is made of the same material as the adhesive used for connecting the substrate 11 and the housing 20. At this time, one end portion of the substrate 11 protruding from the housing 20 and the power supply base 30 may be fixed with an adhesive.

  FIG. 2 is a schematic perspective view showing an example of the power supply cap 30 according to the first embodiment of the present invention. FIG. 3 is a schematic perspective view showing an example of the rigid body 50 according to Embodiment 1 of the present invention. The power supply cap 30 is fixed to a predetermined rigid body 50 when the straight tube LED lamp 1 is manufactured.

  As shown in FIG. 2, the power supply base 30 includes a base body 31 and power supply pins 32.

  The base body 31 is an example of a first base body, has an outer shape of the power supply base 30, and has a bottomed cylindrical shape having an opening and a bottom surface. The base body 31 according to the present embodiment has a bottomed cylindrical shape, and has a circular opening and a disk-shaped bottom surface.

  The base body 31 is made of a resin material such as polybutylene terephthalate (PBT). Here, the power supply cap 30 is produced, for example, by insert molding using a power supply pin 32 and a resin material. Note that the power supply base 30 can be manufactured by press-fitting the power supply pins 32 into the base body 31 that is a resin molded body.

  The power supply pins 32 are an example of a cap pin, and are a pair of conductive pins that receive power for causing the LED module 10 to emit light from an external device such as a lighting fixture. For example, the power feed pin 32 is made of a metal material such as brass. By attaching the power supply pin 32 to the receiving fixture of the lighting fixture, the power supply pin 32 can receive DC power from a power supply device built in the lighting fixture.

  Specifically, the power supply pin 32 is provided so as to penetrate the bottom surface of the base body 31. The power supply pin 32 protrudes outward from the outer surface of the bottom surface of the base body 31 and protrudes from the inner surface of the bottom surface of the base body 31 toward the opening. Although not shown, a portion of the power supply pin 32 that protrudes from the inner surface of the bottom surface of the base body 31 toward the opening is connected to a connection terminal provided on the substrate 11 by a lead wire or the like.

  The power supply base 30 according to the present embodiment is a GX16t-5 base (L-shaped pin base) in a straight tube LED lamp conforming to JIS C 7709-1, and therefore, the power supply pin 32 is L-shaped. .

  Next, the detailed structure of the base body 31 will be described. As shown in FIG. 2, the base body 31 is divided into two regions in the longitudinal direction of the housing 20. That is, the base body 31 includes a narrow region 33 and a wide region 34. The base body 31 has a fitting portion 35 on the side surface.

  The narrow region 33 is a region having an opening area smaller than the wide region 34 in a cross section (XZ cross section) orthogonal to the longitudinal direction (Y-axis direction) of the housing 20. Specifically, the narrow region 33 is a region that is narrower than at least one of the other regions when the base body 31 is divided into a plurality of regions along the Y-axis direction.

  The wide area 34 is an area where the opening area in a cross section (XZ cross section) orthogonal to the longitudinal direction (Y-axis direction) of the housing 20 is larger than the narrow area 33. Specifically, the wide area 34 is an area wider than at least one of the other areas when the base body 31 is divided into a plurality of areas along the Y-axis direction.

  Specifically, the wide region 34 is a region including a portion of the base body 31 that covers one of the end portions of the housing 20. Therefore, the inner diameter of the base body 31 in the wide region 34 is larger than the outer diameter of the end portion of the housing 20. In other words, the opening area of the base body 31 in the wide region 34 in the XZ cross section is larger than the opening area of the housing 20.

  In the present embodiment, as shown in FIG. 2, both the narrow region 33 and the wide region 34 are cylindrical. Therefore, the outer diameter of the narrow region 33 is larger than the outer diameter of the wide region 34. That is, a step is formed on the outer surface of the base body 31.

  For example, the depth (Y-axis direction) of the narrow region 33 is 1 to 30 mm. Moreover, the internal diameter of the narrow area | region 33 is 1-35 mm. In addition, the outer diameter of the narrow area | region 33 is 20-40 mm.

  Moreover, the depth (Y-axis direction) of the wide area | region 34 is 3-40 mm. Moreover, the internal diameter of the wide area | region 34 is 20-40 mm. In addition, the outer diameter of the wide area | region 34 is 21-42 mm.

  The fitting part 35 is an example of a second fitting part. The fitting portion 35 can be fitted to a fitting portion 51 included in a predetermined rigid body 50. The shape of the fitting portion 35 may be a shape for suppressing the rotation of the base body 31 in a state where the fitting portion 35 and the fitting portion 51 are fitted. For example, the fitting part 35 is a convex part protruding outward from the side surface of the base body 31 as shown in FIG. Thereby, fitting with the base body 31 and the rigid body 50 is realizable with simple structures like a convex part.

  The fitting part 35 has two planes (a plane 351 and a plane 352) orthogonal to the short direction (X-axis direction) of the substrate 11. The plane 351 and the plane 352 are planes parallel to the YZ plane. That is, the fitting portion 35 has a substantially uniform width in the X-axis direction. More specifically, the fitting portion 35 has a uniform width in the X-axis direction except for a region including a curved surface 354 described later.

  The fitting portion 35 has a flat surface 353 that is continuous with the bottom surface of the base body 31. The plane 353 is a plane parallel to the XZ plane.

  The fitting part 35 has a curved surface 354 along the side surface of the base body 31. Specifically, the fitting portion 35 has a part of a cylindrical side surface having an outer diameter equal to the outer diameter of the wide region 34 as a curved surface 354. Note that the fitting portion 35 may have a surface parallel to the XY plane instead of the curved surface 354. At this time, it is preferable that the plane instead of the curved surface 354 does not protrude outward from the wide area 34.

  With this configuration, even when the fitting portion 35 is a convex portion, the fitting portion 35 does not protrude outward from the outer surface of the wide region 34 of the base body 31. Further, the fitting portion 35 does not protrude outward from the bottom surface of the base body 31. Therefore, even when the straight tube LED lamp 1 according to the present embodiment is attached to a lighting fixture or the like, the fitting portion 35 does not become an obstacle to the attachment and can be easily attached to a conventional lighting fixture.

  The fitting portion 35 is a part of the side surface of the base body 31 and is integrally formed with the base body 31. In addition, you may comprise the fitting part 35 by providing a convex part in the nozzle | cap | die main body 31 separately.

[First rigid body (part of jig)]
As shown in FIG. 3, the rigid body 50 has a fitting portion 51.

  The rigid body 50 is an example of a predetermined first rigid body, and is, for example, a part of a jig used for manufacturing the straight tube LED lamp 1 according to the present embodiment. The rigid body 50 is used for positioning the feeding base 30. The rigid body 50 is made of, for example, a metal material or a resin material.

  The fitting portion 51 is an example of a first fitting portion, and can be fitted with the fitting portion 35 included in the power supply base 30. The shape of the fitting portion 51 may be a shape for suppressing the rotation of the base body 31 in a state where the fitting portion 35 and the fitting portion 51 are fitted. For example, the fitting part 51 is a recessed part formed in the side surface (upper surface) of the rigid body 50, as shown in FIG. The fitting portion 51 may be a through hole that can be fitted to the fitting portion 35.

[Fitted state between power feeding base and rigid body]
FIG. 4A is a schematic perspective view showing an example of a state where the power supply base 30 and the rigid body 50 according to Embodiment 1 of the present invention are fitted. FIG. 4B is a cross-sectional view showing an example of a state where the power supply base 30 and the rigid body 50 according to Embodiment 1 of the present invention are fitted. Specifically, FIG. 4B shows an AA cross section of FIG. 4A.

  As shown in FIGS. 4A and 4B, in the state where the fitting portion 35 and the fitting portion 51 are fitted, the rotation of the power supply cap 30 is suppressed when the rigid body 50 is fixed. Specifically, when the flat surface 351 and the flat surface 352 of the fitting portion 35 are locked to the rigid body 50, the rotation of the power supply base 30 is suppressed. Note that the rotation is rotation with the rotation axis in the direction from the bottom surface of the base body 31 toward the opening (Y-axis direction), that is, the longitudinal direction of the housing 20 (tube axis direction).

  In the present embodiment, the state where the fitting portion 35 and the fitting portion 51 are fitted indicates a state where at least the rotation of the power supply cap 30 can be suppressed. Specifically, the state where the fitting portion 35 and the fitting portion 51 are fitted is a state where the feeding base 30 is at least impossible to rotate with the tube axis direction as the rotation axis.

  Therefore, for example, in a state where the fitting portion 35 and the fitting portion 51 are fitted, the power supply base 30 may be movable in the tube axis direction relative to the rigid body 50. Further, in a state where the fitting portion 35 and the fitting portion 51 are fitted, the power supply base 30 may be suppressed from moving in any direction relative to the rigid body 50. More specifically, the feeding base 30 and the rigid body 50 may be completely fixed to each other in a state where the fitting portion 35 and the fitting portion 51 are fitted.

[Non-powered cap]
The non-power feeding base 40 is an example of a second base and is a non-power feeding side base. That is, the non-power feeding base 40 has a function of attaching the straight tube LED lamp 1 to a lighting fixture. As shown in FIG. 1, the non-power feeding base 40 is fixed to the other end of the casing 20 or the substrate 11 in the longitudinal direction (Y-axis direction). Note that the non-power supply base 40 may ground (ground) a predetermined region of the LED module 10 via a lighting fixture.

  The non-power supply base 40 is configured in a cap shape so as to cover the other end of the casing 20 in the longitudinal direction. That is, the non-power feeding base 40 has a bottomed cylindrical shape and is provided so as to cover the other end of the casing 20 in the longitudinal direction. For example, the non-power feeding base 40 is bonded to the other end of the housing 20 with an adhesive. In the present embodiment, the non-power feeding base 40 is a cylinder having an opening at one end and a bottom at the other.

  The adhesive used for bonding the non-power feeding base 40 and the housing 20 is, for example, a silicone resin. For example, the adhesive is made of the same material as the adhesive used for connecting the substrate 11 and the housing 20. At this time, the other end of the substrate 11 protruding from the housing 20 and the non-power feeding base 40 may be fixed with an adhesive.

  FIG. 5 is a schematic perspective view showing an example of the non-power supply base 40 according to Embodiment 1 of the present invention. The non-power supply base 40 is fixed to a predetermined rigid body 60 (see FIGS. 6A and 6B) when the straight tube LED lamp 1 is manufactured.

  As shown in FIG. 5, the non-power supply base 40 includes a base body 41 and a non-power supply pin 42.

  The base body 41 is an example of a second base body, has an outer shape of the base for non-power feeding 40, and has a bottomed cylindrical shape having an opening and a bottom surface. The base body 41 according to the present embodiment has a bottomed cylindrical shape, and has a circular opening and a disk-shaped bottom surface.

  The base body 41 is made of a resin material such as polybutylene terephthalate. Here, the non-power supply base 40 is produced by insert molding using the non-power supply pin 42 and a resin material, for example. In addition, the non-power feeding base 40 can also be produced by press-fitting the non-power feeding pins 42 into the base body 41 which is a resin molded body.

  The non-power supply pin 42 is an example of a cap pin, and is an attachment pin for attaching the straight tube LED lamp 1 to a lighting fixture. For example, the non-feed pin 42 is a conductive pin having a T-shaped cross section made of a metal material such as brass. The non-feeding pin 42 is provided so as to penetrate the bottom surface of the base body 41. The non-power feeding pin 42 protrudes outward from the outer surface of the bottom surface of the base body 41 and protrudes from the inner surface of the bottom surface of the base body 41 toward the opening. The non-feeding pin 42 only needs to protrude outward from the outer surface of the bottom surface of the base body 41, and the inner surface side may be embedded in the base body 41.

  Note that, when the non-power supply base 40 grounds a predetermined region of the LED module 10, the non-power supply pin 42 and the substrate 11 are connected.

  Next, the detailed structure of the base body 41 will be described. As shown in FIG. 5, the base body 41 includes a narrow region 43 and a wide region 44 in the longitudinal direction of the housing 20. The base body 41 has a fitting portion 45 on the side surface.

  The narrow region 43 is a region having an opening area smaller than the wide region 44 in a cross section (XZ cross section) orthogonal to the longitudinal direction (Y-axis direction) of the housing 20. Specifically, the narrow region 43 is a region that is narrower than at least one of the other regions when the base body 41 is divided into a plurality of regions along the Y-axis direction.

  The wide area 44 is an area where the opening area in the cross section (XZ cross section) orthogonal to the longitudinal direction (Y-axis direction) of the housing 20 is larger than the narrow area 43. Specifically, the wide area 44 is an area wider than at least one of the other areas when the base body 41 is divided into a plurality of areas along the Y-axis direction.

  Specifically, the wide area 44 is an area including a portion of the base body 41 that covers the other end of the housing 20. Therefore, the inner diameter of the base body 41 in the wide region 44 is larger than the outer diameter of the end portion of the housing 20. In other words, the opening area of the base body 41 in the wide region 44 in the XZ section is larger than the opening area of the housing 20.

  In the present embodiment, as shown in FIG. 5, both the narrow region 43 and the wide region 44 are cylindrical. Therefore, the outer diameter of the narrow region 43 is larger than the outer diameter of the wide region 44. That is, a step is formed on the outer surface of the base body 41.

  For example, the depth (Y-axis direction) of the narrow region 43 is 1 to 30 mm. Moreover, the internal diameter of the narrow area | region 43 is 1-35 mm. In addition, the outer diameter of the narrow area | region 43 is 20-40 mm.

  Moreover, the depth (Y-axis direction) of the wide area | region 44 is 3-40 mm. Moreover, the internal diameter of the wide area | region 44 is 20-40 mm. In addition, the outer diameter of the wide area | region 44 is 21-42 mm.

  Here, it is preferable that the base body 31 of the power supply base 30 and the base body 41 of the non-power supply base 40 have a common shape. For example, in the present embodiment, the narrow region 33 of the power feeding base 30 and the narrow region 43 of the non-power feeding base 40 have the same inner diameter, outer diameter, and width in the tube axis direction. Similarly, the wide area 34 of the power supply base 30 and the wide area 44 of the non-power supply base 40 have the same inner diameter, outer diameter, and width in the tube axis direction.

  The fitting part 45 is an example of a fourth fitting part. The fitting portion 45 can be fitted into a fitting portion 61 included in a predetermined rigid body 60. The shape of the fitting part 45 should just be a shape for suppressing rotation of the nozzle | cap | die main body 41 in the state which fitted the fitting part 45 and the fitting part 61. FIG. For example, the fitting part 45 is a convex part protruding outward from the side surface of the base body 41 as shown in FIG. Thereby, fitting with the base body 41 and the rigid body 60 is realizable with simple structures like a convex part.

  The specific shape of the fitting portion 45 is the same as that of the fitting portion 35. Therefore, the fitting portion 61 that can be fitted to the fitting portion 45 is also the same as the fitting portion 51 that can be fitted to the fitting portion 35. For this reason, the rigid body 50 and the rigid body 60 can be made into the same shape. That is, the rigid body 60 is the same as the rigid body 50 shown in FIG. 3, for example.

[Second rigid body (part of jig)]
The rigid body 60 is an example of a predetermined second rigid body, and is, for example, a part of a jig used for manufacturing the straight tube LED lamp 1 according to the present embodiment. The rigid body 60 is used for positioning the non-power feeding base 40. The rigid body 60 is made of, for example, a metal material or a resin material.

  The fitting portion 61 is an example of a third fitting portion, and can be fitted to the fitting portion 45 included in the non-power feeding base 40. The shape of the fitting part 61 should just be a shape for suppressing rotation of the nozzle | cap | die main body 41 in the state which fitted the fitting part 45 and the fitting part 61. FIG. For example, the fitting portion 61 is a recess formed on the side surface (upper surface) of the rigid body 60. The fitting portion 61 may be a through hole that can be fitted to the fitting portion 45.

[Fitted state of non-power supply cap and rigid body]
FIG. 6A is a schematic perspective view showing an example of a state in which the non-power feeding base 40 and the rigid body 60 according to Embodiment 1 of the present invention are fitted. FIG. 6B is a cross-sectional view showing an example of a state where the non-power feeding base 40 and the rigid body 60 according to Embodiment 1 of the present invention are fitted. Specifically, FIG. 6B shows a BB cross section of FIG. 6A.

  As shown in FIGS. 6A and 6B, in the state where the fitting portion 45 and the fitting portion 61 are fitted, when the rigid body 60 is fixed, the rotation of the non-power feeding base 40 is suppressed. Here, the rotation is rotation about the rotation axis in the direction from the bottom surface of the base body 41 toward the opening (Y-axis direction), that is, the longitudinal direction of the housing 20 (tube axis direction).

  In the present embodiment, as in the case of the power supply cap 30, the state in which the fitting portion 45 and the fitting portion 61 are fitted can suppress at least the rotation of the non-power feeding cap 40. Indicates the state. Specifically, the state in which the fitting portion 45 and the fitting portion 61 are fitted is a state in which the non-power-feeding cap 40 is at least impossible with the tube axis direction as the rotation axis.

  Therefore, for example, in a state where the fitting portion 45 and the fitting portion 61 are fitted, the non-power feeding base 40 may be movable in the tube axis direction relative to the rigid body 60. Further, in a state where the fitting portion 45 and the fitting portion 61 are fitted, the non-power feeding base 40 may be restrained from moving in any direction relative to the rigid body 60. More specifically, the non-power feeding base 40 and the rigid body 60 may be completely fixed to each other in a state where the fitting portion 45 and the fitting portion 61 are fitted.

[Manufacturing method of straight tube LED lamp]
Then, the manufacturing method of the light source for illumination which concerns on Embodiment 1 of this invention is demonstrated.

  The manufacturing method of the light source for illumination which concerns on Embodiment 1 of this invention is equipped with the elongate board | substrate with which the light emitting element is arrange | positioned on the surface, an elongate housing | casing, and a 1st nozzle | cap | die and a 2nd nozzle | cap | die. It is a manufacturing method of the light source for illumination. The method for manufacturing an illumination light source according to the present embodiment includes a step of arranging a substrate in a housing and a step of fixing the first base and the second base to the longitudinal ends of the housing or the substrate, respectively. In the fixing step, the first cap is fitted in a state in which the first fitting portion and the second fitting portion are fitted, and in a state in which the third fitting portion and the fourth fitting portion are fitted. At least one of the main body and the second base body is fixed to the end of the housing or the substrate.

  Below, the manufacturing method of the above-mentioned straight tube | pipe LED lamp 1 which is an example of the light source for illumination is demonstrated in detail using drawing.

  FIG. 7 is a diagram illustrating an example of a manufacturing process of the straight tube LED lamp 1 according to Embodiment 1 of the present invention.

  First, as shown in FIG. 7A, the long substrate 11 having the LED elements 12 disposed on the surface is disposed in the housing 20. That is, the LED module 10 is disposed in the housing 20. At this time, a part of the LED module 10 may be disposed so as to be accommodated in the housing 20, or may be disposed so that the end portion protrudes from the housing 20.

  Subsequently, as shown in FIG. 7B, the feeding base 30 is disposed on the rigid body 50 and the non-feeding base 40 is disposed on the rigid body 60. Specifically, the fitting portion 35 of the power feeding base 30 and the fitting portion 51 of the rigid body 50 are fitted. Further, the fitting portion 45 of the non-power feeding base 40 and the fitting portion 51 of the rigid body 60 are fitted.

  At this time, the rigid body 60 is a position in the rotation direction with the longitudinal direction of the housing 20 as the rotation axis, and the relative position with respect to the rigid body 50 is fixed. Specifically, the rigid body 50 and the rigid body 60 are part of the jig 70.

  As shown in FIG. 7B, the jig 70 includes a pedestal 71, a rigid body 50, and a rigid body 60. The rigid body 50 and the rigid body 60 are disposed on the pedestal 71 and can be translated in the tube axis direction. For example, a guide rail is formed on the base 71 so that the rigid body 50 and the rigid body 60 can be translated in the tube axis direction. Thereby, the rigid body 50 and the rigid body 60 can be translated in the tube axis direction in a state in which the rotation of each other is suppressed.

  Here, the fitting portion 35 of the feeding base 30 and the fitting portion 45 of the non-feeding base 40 are formed at positions facing each other in the longitudinal direction of the housing 20. In the example shown in FIG. 7B, both the fitting portion 35 and the fitting portion 45 are formed in the back surface direction of the substrate 11.

  Thereby, since the rigid body 50 fitted to the fitting portion 35 and the rigid body 60 fitted to the fitting portion 45 can also be arranged at positions facing each other, for example, a jig including the rigid body 50 and the rigid body 60. 70 can be realized with a simple configuration.

  Subsequently, as shown in FIG. 7C, the power supply base 30 and the non-power supply base 40 are respectively fixed to the ends of the casing 20 or the LED module 10 in the longitudinal direction. Specifically, the base body 31 of the power supply base 30 and the base body 41 of the non-power supply base 40 are connected to the end of the housing 20 or the LED module 10 using the adhesive 80. More specifically, the base body 31 and the base body 41 are connected to the LED module 10 and the housing 20, respectively.

  In the fixing step shown in FIG. 7C, the fitting portion 35 of the power feeding base 30 and the fitting portion 51 of the rigid body 50 are fitted together, and the fitting portion 45 of the non-power feeding base 40 is provided. The base body 31 and the base body 41 are both bonded to the ends of the housing 20 and the LED module 10 using an adhesive 80 in a state where the fitting portion 61 of the rigid body 60 is fitted. Since the rigid body 50 and the rigid body 60 can be translated in the tube axis direction of the housing 20 as described above, the positional relationship in the rotational direction between the feeding base 30 and the non-feeding base 40 and the housing 20 is determined. The power supply base 30 and the non-power supply base 40 can be easily bonded to the housing 20 and the LED module 10 while being kept.

  The adhesive 80 is an adhesive made of, for example, a silicone resin or cement. By using the adhesive 80, the housing 20 or the substrate 11, the base body 31, and the base body 41 can be bonded more firmly.

  Through the above steps, the straight tube LED lamp 1 is manufactured as shown in FIG.

  In the fixing step shown in FIG. 7C, one of the bases may be fixed to the housing 20 in advance. For example, after the non-power feeding base 40 is bonded to the housing 20 and the LED module 10 using the adhesive 80, the fitting portion 45 and the rigid body 60 of the non-power feeding base 40 in a state where the housing 20 is bonded. The fitting portion 61 may be fitted. Further, the feeding base 30 and the housing 20 are bonded using the adhesive 80 in a state where the fitting portion 35 of the feeding base 30 and the fitting portion 51 of the rigid body 50 are fitted.

  Thus, the fitting part 35 of the power feeding base 30 and the fitting part 51 of the rigid body 50 are fitted together, and the fitting part 45 of the non-power feeding base 40 and the fitting part 61 of the rigid body 60 At least one of the base body 31 and the base body 41 may be fixed to the end of the housing 20 or the LED module 10. That is, the base body mounted first among the base body 31 and the base body 41 may be freely connected regardless of whether or not the fitting portion is fitted.

  In the present embodiment, the end of the housing 20 and the inside of the base body 31 or the base body 41 do not have a structure for locking each other. That is, when the casing 20 and the base body 31 or the base body 41 are connected, they can freely rotate with each other.

  Therefore, by connecting the end portion of the housing 20 to the base body 31 and the base body 41 using the adhesive 80, rotation is prevented, and the power supply base 30 and the non-power supply base 40 are positioned accurately. Can be installed. In the present embodiment, the positioning in the rotation direction can be accurately performed by providing the fitting portion in each of the base bodies.

  As described above, the method of manufacturing the illumination light source according to the present embodiment includes a long substrate having a light emitting element disposed on the surface, a long casing, the first base, and the second base. The first base has a first base body having a second fitting portion on the side surface that can be fitted to a first fitting portion of a predetermined first rigid body. And the second base is fitted in the third fitting portion of the second rigid body, which is in the rotational direction with the longitudinal direction of the casing as the rotational axis and fixed relative to the first rigid body. The manufacturing method includes a step of placing the substrate in the housing, and a first base and a second at the end of the housing or the substrate in the longitudinal direction. A step of fixing each of the caps, and in the step of fixing, the first fitting portion and the second fitting portion are fitted, and the third fitting portion In a state where the fitting the fourth fitting portion, for securing at least one of the first base body and the second base body on an end portion of the casing or substrate.

  As a result, at least one of the cap and the housing in a state in which the first fitting portion and the second fitting portion are fitted, and in a state in which the third fitting portion and the fourth fitting portion are fitted. Alternatively, the substrate is fixed. Since the relative position in the rotation direction is fixed between the first rigid body in which the first fitting portion is formed and the second rigid body in which the third fitting portion is formed, the relative in the rotation direction of the two caps The specific position is fixed at a position determined by the first rigid body and the second rigid body. Accordingly, since the position of the base in the rotation direction can be determined simply by fitting the fitting portions, the base can be easily mounted at the correct position.

  For example, when the housing, the first base body, and the second base body are cylindrical, the first base body and the second base body rotate with respect to the housing, so the first base body and the second base body. Positioning becomes more difficult. On the other hand, in the state in which the first fitting portion and the second fitting portion are fitted as described above, and in the state in which the third fitting portion and the fourth fitting portion are fitted. By fixing at least one of the housing and the housing or the substrate, the base can be easily mounted at the correct position.

  Further, the second fitting portion and the fourth fitting portion may be convex portions, concave portions, or through holes.

  Thereby, the fitting between the base body and the rigid body can be realized with a simple structure.

  Further, in the fixing step, the first base body and the second base body may be bonded to the end of the housing or the substrate using an adhesive.

  Thereby, a housing | casing or a board | substrate, and a 1st nozzle | cap | die main body and a 2nd nozzle | cap | die main body can be adhere | attached more firmly by using an adhesive agent.

  In the fixing step, the first base body and the second base body may be bonded to the substrate and the housing, respectively.

  As a result, since the base is bonded to both the substrate and the housing, the position of the base and the substrate can also be determined. When the illumination light source is attached to the luminaire, the correct direction (for example, below the luminaire) Etc.) can be adjusted to the light irradiation direction.

  In addition, an illumination light source according to one embodiment of the present invention includes a long housing, a long substrate which is disposed in the housing and has a light-emitting element on a surface thereof, and the longitudinal direction of the housing or the substrate A first base and a second base fixed to each end of the first base, and the first base has a second fitting portion that can be fitted into a first fitting portion of a predetermined first rigid body. The second base has a first base body on a side surface, and the second base has a second rigid body that is in a rotational direction with the longitudinal direction of the housing as a rotational axis and fixed relative to the first rigid body. It has the 2nd nozzle | cap | die main body which has a 4th fitting part which can be fitted to a 3rd fitting part on the side.

  Thereby, the positional relationship between the first base and the second base can be determined using the second fitting portion and the fourth fitting portion at the time of manufacture, and the first base and the second base are in an accurate position. An attached light source for illumination can be provided.

  Further, the second fitting portion and the fourth fitting portion may be convex portions, concave portions, or through holes.

  Thereby, the fitting between the base body and the rigid body can be realized with a simple structure.

  The first base body includes a wide region in the longitudinal direction of the housing and a narrow region having an opening area in a cross section orthogonal to the longitudinal direction smaller than the wide region, and the second shape is formed in the narrow region. May be.

  Thereby, by providing the fitting portion in the narrow region, for example, even when the fitting portion is a convex portion, the fitting portion can be prevented from protruding outward from the outer surface of the base body. . Therefore, when the light source for illumination is attached to a lighting fixture or the like, the fitting portion does not become an obstacle to the attachment, and can be easily attached to a conventional lighting fixture or the like.

  The second fitting portion and the fourth fitting portion may be formed at positions facing each other in the longitudinal direction of the housing.

  Thereby, since the 1st rigid body fitted to the 2nd fitting part and the 2nd rigid body fitted to the 4th fitting part can also be arranged in the mutually opposing position, for example, the 1st rigid body and the 1st rigid body A jig having two rigid bodies can be realized with a simple configuration.

  Moreover, the same shape may be sufficient as a 2nd fitting part and a 4th fitting part.

  Thereby, since the shape of each fitting part of a 1st base body and a 2nd base body is the same, a 1st rigid body and a 2nd rigid body can be made into the same shape.

  Further, the first base body and the second base body may be respectively bonded to the end of the housing or the substrate with an adhesive.

  Thereby, a housing | casing or a board | substrate, and a 1st nozzle | cap | die main body and a 2nd nozzle | cap | die main body can be adhere | attached more firmly by using an adhesive agent.

  In the present embodiment, the configuration in which the fitting portion 35 of the power feeding base 30 and the fitting portion 45 of the non-power feeding base 40 are formed at positions facing each other in the longitudinal direction of the housing 20 has been described. Not limited to this. For example, the fitting portion 35 may be formed in the back surface direction of the substrate, and the fitting portion 45 may be formed in the top surface direction of the substrate. Or the fitting part 35 and the fitting part 45 may be formed in the position which shifted | deviated 90 degree | times (or 45 degree | times, 180 degree | times etc.) in the rotation direction which makes a tube axis direction a rotation axis.

  Further, FIG. 2 shows an example in which the base body 31 is divided into two regions, but it may be divided into three or more regions. In this case, the narrow region 33 may be the narrowest region among the plurality of regions, or may be a region other than the widest region. Similarly, the wide area 34 may be the widest area among the plurality of areas, or may be an area other than the narrowest area.

  Further, although an example in which the narrow region 33 is the bottom side region and the wide region 34 is the opening side region has been described, the narrow region may be the opening side and the wide region 34 may be the bottom side. Alternatively, the narrow region 33 may be formed so as to sandwich the two wide regions 34. On the contrary, the wide area 34 may be formed so that the two narrow areas 33 are sandwiched therebetween.

(Modification of Embodiment 1)
Then, the modification of Embodiment 1 of this invention is demonstrated. In Embodiment 1, although the case where the fitting part which a base body has is a convex part was demonstrated, the fitting part does not need to be a convex part. For example, the fitting portion may be a recess or a through hole. The fitting portion may have an uneven shape.

  In the following description of the modification of the first embodiment, a power supply base that is an example of the first base is described, but the same configuration is applied to a non-power supply base that is an example of the second base. Can do. The description of the same configuration as that of the first embodiment will be omitted, and different points will be mainly described.

[Modification of power supply cap]
FIG. 8 is a schematic perspective view showing an example of a power supply cap 30a according to a modification of the first embodiment of the present invention. FIG. 9 is a schematic perspective view showing an example of a rigid body 50a according to a modification of the first embodiment of the present invention.

  The power supply base 30 a is an example of a first base, and is a power supply base for supplying power to the LED module 10. The power supply base 30 a is fixed to one of the ends of the casing 20 or the substrate 11 in the longitudinal direction (Y-axis direction). The power supply cap 30a receives power for lighting the LED element 12 from the outside of the lamp.

  The power supply cap 30 a is configured in a cap shape so as to cover one end of the casing 20 in the longitudinal direction. That is, the power supply base 30 a has a bottomed cylindrical shape and is provided so as to cover one end of the casing 20 in the longitudinal direction. In the present embodiment, the power supply cap 30a is a cylinder having an opening at one end and a bottom at the other.

  As shown in FIG. 8, the power supply base 30 a includes a base body 31 a and power supply pins 32.

  The base body 31a is an example of a first base body and has a bottomed cylindrical shape that forms an outline of the power supply base 30a and has an opening and a bottom surface. The base body 31a according to the modification of the present embodiment has a bottomed cylindrical shape, and has a circular opening and a disk-shaped bottom surface.

  The base body 31a is made of a resin material such as polybutylene terephthalate. The base body 31a is produced, for example, by insert molding using the power supply pin 32 and a resin material.

  Next, the detailed structure of the base body 31a will be described. As shown in FIG. 8, the base body 31a has a fitting portion 35a on the side surface.

  The fitting part 35a is an example of a second fitting part. The fitting portion 35a can be fitted to a fitting portion 51a included in a predetermined rigid body 50a. The shape of the fitting part 35a should just be a shape for suppressing rotation of the nozzle | cap | die main body 31a in the state which fitted the fitting part 35a and the fitting part 51a. For example, as shown in FIG. 8, the fitting portion 35a is a concave portion that is recessed inward from the side surface of the base body 31a. Note that the fitting portion 35a may be a through-hole penetrating the side surface of the base body 31a. Thereby, fitting with the base body 31a and the rigid body 50a is realizable with a simple structure like a recessed part or a through-hole.

  The fitting portion 35 a has two planes (a plane 351 a and a plane 352 a) orthogonal to the short direction (X-axis direction) of the substrate 11. The plane 351a and the plane 352a are planes parallel to the YZ plane. That is, the fitting portion 35a has a substantially uniform width in the X-axis direction. More specifically, the fitting portion 35a has a uniform width in the X-axis direction except for a region including a curved surface 354a described later.
