Description

  The present invention relates to a fluorescent lamp type semiconductor lamp that can be used as it is in a lighting apparatus for fluorescent lamps, and in particular, a fluorescent lamp that can be used as a substitute for a straight tube type fluorescent lamp having a length approximately twice as long by connecting two lamps. The present invention relates to a lamp-type semiconductor lamp, and a hanging support for hanging and supporting a central portion of the lamp-type semiconductor lamp when used in a long form.

  Semiconductor lamps with built-in semiconductor light-emitting elements such as LEDs and organic EL have lower power consumption and better durability than fluorescent lamps (fluorescent tubes), which have been the mainstream in the past. In recent years, it has been rapidly spreading. As an example, there is known a product in which a semiconductor lamp having a built-in LED is made into a straight tubular fluorescent lamp type and can be used for a conventional lighting apparatus for a fluorescent lamp.

  Such fluorescent lamp type semiconductor lamps are mainly 20W type and 30W type short lamps for home use, but 40W type and 110W type lamps are mainly used for business use. Of these, the longest 110W type is widely used in large-scale facilities such as factories, but the total length is about 240cm, which is inconvenient to handle and store, and also increases the transportation cost. There is.

  In order to solve this problem, Japanese Utility Model Registration No. 3162747 proposes a split-type fluorescent lamp type semiconductor lamp in which a 110W type fluorescent lamp type semiconductor lamp is divided into two parts and connected in a tiltable or separable manner at the central portion. Therefore, it is excellent in convenience in that it can be reduced to a half length during transportation and storage.

  However, facilities that use 110W fluorescent lamp type semiconductor lamps often use 40W type lamps as well, whereas this two-split lamp is used as a 40W type lamp in a divided state. I can't. In addition, if two lamp units with built-in LED circuit boards and converters are connected to form a 110W fluorescent lamp type semiconductor lamp, it will be much heavier than a fluorescent lamp of the same length, and a large force will be applied to the central part. Although it is easy to bend and the connection / mounting state is likely to be unstable, this device does not provide means for increasing the connection strength of the connection portion or preventing the connection device from falling off the lighting device.

  Therefore, in Japanese Patent No. 5014496, in addition to the configuration in which one base of the 40 W fluorescent lamp type semiconductor lamp is detachable, and the end face from which the base is removed is used as a joint surface, and the two are fitted in a concave and convex shape, A fluorescent lamp type semiconductor lamp has been proposed in which the outer peripheral surface of the connecting portion is held by an intermediate holder to reinforce the connection and make the 110W type. Thereby, when not connected, it can be used as a 40W type, and when it is long, the connected state is reinforced by the intermediate holder to ensure stability and safety.

  However, in this fluorescent lamp type semiconductor lamp, the intermediate holder when used in a long length is divided vertically, and after attaching the upper member to the ceiling or lighting equipment, the lamp is attached to the lighting equipment, and then the lower member is attached. And fix it. Therefore, in addition to the labor required for the lamp mounting operation, it is not easy to adjust the distance between the lamp central portion and the fixed surface side which are different for each type of lighting equipment. In addition, this fluorescent lamp type semiconductor lamp does not have a built-in lighting circuit (resistance / rectifying means) that leads to an increase in weight because the coupling force due to the unevenness of the connecting portion is not sufficient, and the power supply socket provided on the base A method of connecting a dedicated power supply line is adopted, and there is a drawback that it cannot be used as it is for an existing fluorescent lighting device.

  On the other hand, the utility model registration No. 3173660 is common in that a dedicated power supply line is required, but the opening ends from which one of the caps of the two 40 W fluorescent lamp type semiconductor lamps are removed are opposed to each other. In addition to inserting and connecting a square or U-shaped connecting bracket to the upper radiating tube side to make it 110W, it is proposed to fix a connecting reinforcing plate for tightening the connecting bracket with a screw on the upper surface side of the connecting portion The central convex portion of the connection reinforcing plate is fixed to the ceiling or the lighting device side via a screw or a three-stage push lock.

  If this method is adopted, the connection reinforcement plate is screwed from the outside with the connection fittings inserted into both opening ends, and the connection becomes firm, and the central convex portion of the connection reinforcement plate is fixed with a screw or a push lock. Fixing to lighting equipment makes it difficult to drop off. However, this method also requires a dedicated connector and cannot be used as it is for existing fluorescent lamp lighting equipment. At the time of mounting, two 40W type fluorescent lamp type semiconductor lamps are connected by connecting brackets to strengthen the connection. After fixing the plate to the 110W shape by screwing it, it is necessary to fix it by groping on the back side of the connecting portion in a state where it is mounted or held on the lighting device.

  For this reason, when a fluorescent lamp type semiconductor lamp having an extremely long length of about 2.4 m is fixed to the ceiling or the lighting device side, a difficult work in an unstable high place is required. In addition, push-lock type fixing is easier than the case of screws and distance adjustment is possible to some extent, but it is a separate part that is inserted into the insertion hole of the connection reinforcing plate, so the number of parts increases. In addition to increasing the cost, there is a problem that the mounting state tends to become unstable by swinging at the insertion portion to the connection reinforcing plate.

Utility Model Registration No. 3162747 Japanese Patent No. 5014496 Utility Model Registration No. 3173660

By inserting the engaging claw into the engaging notch from the inside and fixing the connector to the heat radiating tube so that it cannot be removed, the procedure is further simplified. A firm connection is ensured.

In addition, a lighting body having a rectifying means and a semiconductor light emitting element are incorporated in a cylindrical main body whose upper side is a metal radiation tube and whose lower side is a resin cover, and lighting equipment for fluorescent lamps is provided at both ends of the main body.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the drawings referred to in the following description, the main body of the fluorescent lamp type semiconductor lamp is expressed shorter than the actual one because of the display space.

  FIG. 1 shows a fluorescent lamp type semiconductor lamp 1A of the present embodiment. This fluorescent lamp type semiconductor lamp 1A is a 110W type (total length: 2367 mm) fluorescent lamp type LED lamp that is assumed to be used by being mounted on a 110W type fluorescent lamp illumination device, and is a 40W type (total length: 1198 mm) fluorescent lamp. Two lamp-type semiconductor lamps 2 (refer to FIG. 4) are connected to be elongated, and adapters 24, 24 for connecting / attaching to a socket portion of a 110W fluorescent lamp illumination device are connected to both ends. It will be.

  A 40W fluorescent lamp type semiconductor lamp 2 shown in FIG. 4 has a semiconductor light-emitting element formed on a cylindrical main body 20A composed of a heat-radiating cylinder 21A made of an aluminum alloy and a lower half made of a resin-made cover 22 having translucency. The circuit board 25 having the LED 200 as an element and a lighting circuit having a rectifier circuit and a resistor are built in (see FIG. 2), and a base for mounting on both ends of the socket part of a lighting apparatus for 40 W fluorescent lamps 23, 23, and only one of the caps 23 is connected to the internal lighting circuit, and the other cap 23 is not electrically connected and is detachable. It can be mounted on the device as it is, and can be used in place of a 40W fluorescent lamp.

  Referring to the exploded perspective view of FIG. 3, the end side of the main body 20A from which the detachable base 23 of the fluorescent lamp type semiconductor lamp 2 is removed is an open end opened in a semicircular shape in the hollow heat radiating cylinder 21A. 21a and screw insertion holes 210 and 210 as an engaging structure for connection are provided in the upper peripheral wall, and two of them are connected by a synthetic resin bowl-shaped oblong member with the opening ends 21a facing each other. Are inserted into the respective open ends 21a to form a long 110W fluorescent lamp type semiconductor lamp 1A.

  Referring to the longitudinal sectional view of FIG. 2, screw holes 62 that are engaging means are respectively inserted into the screw insertion holes 210 from the outside of the heat radiating cylinder 21A, and screw holes formed on the upper surfaces of the insertion portions 30 and 30 of the connector 30A. The two 40W fluorescent lamp type semiconductor lamps 2 and 2 are firmly connected in a state in which they cannot be removed in normal use by being screwed into the respective 300 (see FIG. 3) and engaged with each other. . In addition, by attaching the bases 23, 23 on both ends to the sockets of the 110W fluorescent lamp lighting equipment via the adapters 24, 24, the bases 23 are not electrically connected at the central connecting portion. , 23 are connected to the power source side, and are used in place of the straight tube 110 W type fluorescent lamp. Furthermore, by using the coupling tool 30A as a synthetic resin molded article, the increase in weight of the central portion of the long lamp that is easily bent is minimized as compared with the conventional example in which the coupling tool 30A is sufficiently secured while the coupling tool 30A is secured. Making it possible.

  In the present embodiment, the hanging support 41A is fastened and attached to the connecting portion that is the central portion of the elongated 110W fluorescent lamp type semiconductor lamp 1A, and the hanging shafts 41b and 41c are connected to the lighting device. The center part is supported in a suspended state by fitting it in a hanging hole that opens on the side (or ceiling plate), and is secured by hanging. It is characterized by the fact that it has been stabilized to make it difficult for it to fall off the lighting equipment even when there is vibration such as an earthquake.

  Referring to FIG. 5, such a hanging support 41A is a synthetic resin molded product having appropriate elasticity. However, as shown in the front view of FIG. The cross-sectional shape in the right-angled direction is a round bottom flask with an open upper end, and is held upward from the upper end sides of the holding portion 41a that is round and curved in a cylindrical shape so as to hold the connecting portion while closely contacting the outer peripheral surface of the connecting portion. In addition, a pair of latching shafts 41b and 41c are provided that extend substantially parallel to each other and are integrally fitted into the suspension hole on the fixed surface side and latch on the suspension hole side.

  As will be described later, the suspension support 41A has an insertion hole 42a that is a substantially rectangular part for inserting and rotating a pair of latching shafts 41b and 41c up and down and fastening them to the connecting portion side. It is used in combination with the hook-shaped fastening part 42 (see FIG. 5C).

  On the other hand, each of the pair of latching shafts 41b and 41c has a substantially rectangular cross-sectional shape in the direction perpendicular to the extending direction (vertical direction) (see FIG. 6), and the surfaces constituting one long side have a predetermined width. The surface of the other long side is opposed to each other in a state of being elastically openable and closable, and a hook-like barb 410 as a latching structure extending in the centrifugal direction is vertically arranged in a plurality of stages. As a result, they are symmetrical with respect to each other.

  In order to fasten the suspension support 41A to the connecting portion, before connecting the main bodies 20A and 20A, the holding portion 41a of the suspension support 41A is inserted into one end of the main body 20A, After the connection, as shown in the plan view of FIG. 6 (A), the fastening part 42 is paired with the pair of retaining shafts 41b in the direction in which the long diameter of the insertion hole 42a coincides with the opening / closing direction of the pair of retaining shafts 41b, 41c. , 41c are inserted from above with a predetermined width open, and then moved to the base end side of the latching shafts 41b, 41c and stopped.

  Then, as shown in FIG. 6 (B), the short axis of the insertion hole 42a is rotated 90 degrees around the axis (clockwise direction) at the lower position of the barbs 410 on the base end side of the latching shafts 41b and 41c. The direction matches the opening and closing direction. Then, the latching shafts 41b and 41c move in the proximity direction while sliding on the inner circumferential surface of the insertion hole 42a, and the latching shaft 41b is located at the inner circumferential portion with a small interval at the position where the opening / closing direction coincides with the minor axis. 41c is sandwiched between the opposed surfaces, the pair of latching shafts 41b and 41c are integrated, and the holding portion 41a is fastened and fixed to the outer peripheral side of the connecting portion.

  As described above, the connecting portion which is the central portion of the fluorescent lamp type semiconductor lamp 1A which is elongated by a simple procedure of inserting the hook-shaped suspension support 41A through the latching shafts 41b and 41c and rotating it 90 degrees. It will be attached by fastening to. Further, the integrated latching shafts 41b and 41c are fixed and supported only by being inserted into the hanging holes of the lighting device (or the ceiling plate). By further rotating 42 in the release direction, the latching shafts 41b and 41 can be opened in the suspension hole by their elastic repulsive force, which makes it more difficult to come off.

  In addition, since the push lock is configured by providing a plurality of barbs 410 as the latching structure in the vertical direction on the outer peripheral side of the integrated latching shafts 41b and 41c, the central portion of the lamp can be changed by changing the insertion depth. It is also possible to easily cope with fluctuations in the distance between and the fixed surface side. Furthermore, since the latching shafts 41b and 41c are an integral part of the holding part 41a fastened to the connecting part, the cost can be reduced compared with the conventional example in which the retaining part 41a is a separate part, and the joint part can be swung. No stability and excellent stability.

  By adopting such a method in the present embodiment, when the elongated fluorescent lamp type semiconductor lamp 1A is mounted on a lighting device, the hanging support tool 41A remains attached to the connecting portion. The stop shafts 41b, 41 can be inserted and fixed in the upper suspension holes, and a stable and safe mounting state can be secured without requiring labor.

  The hanging support tool 41A is preferably fastened with the center line in the width direction coincident with the contact line of the end surfaces facing the main bodies 20A, 20A, as shown in FIG. By adopting a positional relationship in which the side surfaces of the screws 62 and 62 are in contact with both end surfaces of the holding portion 41a in the mounted state, accurate positioning can be easily performed. Alternatively, as shown in the application example of FIG. 5D, wedge-shaped convex portions 412 and 412 are provided along the inner peripheral surface center line of the holding portion 41a, and the tip is covered by the reduction of the holding portion by the fastening operation. 22 and 22 may be inserted into the gap between the end faces (formed by the width of the separator 30b (see FIG. 3)).

  FIG. 7 is an exploded perspective view showing a case where a connector 30B as a modification of the connector 30A shown in FIG. 3 is used. This example is characterized in that a ring-shaped cover frame 31b is provided in order to prevent dust and the like from entering through the gaps of the connecting portions. Since it is the structure connected in the state which fitted the edge part side of the covers 22 and 22, a connection state will become still more rigid.

  FIG. 8 is an exploded perspective view of a 110 W fluorescent lamp type semiconductor lamp 1B according to the second embodiment of the present invention. In the present embodiment, the engagement structure of the radiating cylinder 21B is not the screw insertion hole 210 but the engagement notches 211 and 211 penetrating through the upper part of the peripheral wall, and the engagement means is not the screw 62 but the connector 30C. The engaging claws 320 project from the corresponding positions of the outer peripheral surfaces of the insertion portions 32 and 32, respectively, and are characterized in that the connecting operation can be further simplified.

  The engaging claw 320 as the engaging means does not stop the operation in the insertion direction at the time of insertion, but has a hook-like structure that stops against the operation in the removal direction while being engaged with the engagement notch 211. The insertion portions 32 and 32 of the coupling tool 30C are inserted from the open ends 21a and 21a, respectively, and the engagement claws 320 are engaged with the engagement notches 211 from the inside at the coupling position. Since the tool 30C is fixed to the heat radiating cylinders 21B and 21B so as not to be removed, a firm connection state is secured by a simpler procedure.

  In this embodiment, when the connecting tool 30C is removed from the connected state, the upper end side of the engaging claw 320 exposed in the engaging notch 211 is pushed from the outside by the tip of the driver or the like to be immersed. It can be pulled out. Moreover, when the resistance of the engaging claw 320 is too strong at the time of insertion and removal, a slit may be provided so that this can be elastically immersed in the upper surface of the insertion portion of the connector 30C.

  FIG. 9A shows a connector 30D as an application example having a configuration different from the above-described connectors 30A, 30B, and 30C. The connector 30D includes both screw holes 330 and 330 similar to the screw holes 300 of the connector 30A and engagement claws 340 and 340 similar to the engagement claws 320 of the connector 30C. It is assumed that harmony between the firmness of the machine and the simplification of the connection work will be realized.

  On the other hand, FIG. 9B shows a coupling tool 30E as a modification of the coupling tool 30A described above, extending the left and right lower ends of the separator 30b of the coupling tool 30A, and connecting the base to the end side of the heat radiating cylinder 21A. 23 is provided with a separator 34b formed by extending insertion bars 340 to be inserted into screw holes formed to connect and fix 23 in the opposite directions, and a more solid connection state can be secured. It is said.

  FIG. 10 shows connecting tools 30F, 30G, and 30H as another application example of the connecting tool 30A of FIG. 1, and a predetermined range of the insertion portion has a cross-sectional shape perpendicular to the longitudinal direction of the main body and a hollow half shape. By inserting each from the open ends of the circular radiating cylinders 21C and 21D, the radiating cylinders 21C and 21D are in contact with both the predetermined range of the curved upper inner peripheral surface and the central portion of the flat bottom surface inside the radiating cylinders 21C and 21D. It is characterized in that the cross-sectional shape in the perpendicular direction is substantially T-shaped.

  That is, FIG. (A) shows a cross-sectional view of the insertion portion when the connecting tool 30F having a T-shaped cross section is inserted and connected from the open ends of the opposing heat radiation cylinders 21C and 21C, and FIG. Both ends of the curved portion are further extended downward, and flanges 360 and 360 are formed with the distal end side being inserted into and engaged with screw holes 250 and 250 for fixing the base 23 of the heat radiating cylinder 21C. A connecting tool 30G is shown. On the other hand, FIG. (C) shows a coupling tool 30H formed by projecting engagement claws 350, 350 for engaging with the engagement notches 212 on the upper surface side of the coupling tool 30G.

  In this way, the connecting tool has a T-shaped cross section and is configured to contact both the inner curved surface and the bottom surface of the heat radiating cylinder, thereby increasing the strength of the connecting tool while minimizing the increase in weight of the connecting tool. In addition, the cross-sectional shape with the gap has an advantage that the spatial communication at the connecting portion is hardly hindered. In addition, the cross-sectional shape is the same when it is an umbrella shape as well as a T shape. Further, it goes without saying that it is possible to combine the respective features of the above-described couplers 30A, 30B, 30C, 30D, 30E, 30F, 30G, and 30H so that the respective features are exhibited in combination.
