JP, 2016-167438, A

By the way, in the invention of Patent Document 1, a load may be applied to the holding electrode during storage or transportation after temporarily assembling the module, and the spring performance of the holding electrode may deteriorate during final assembly of the product. ..

The present invention has been made in view of the above points, and an object thereof is to suppress deterioration of spring performance of a leaf spring-shaped conductive member.

The present invention is directed to a holder including a first insulating member and a second insulating member for sandwiching and holding a light emitting module having a predetermined thickness in the thickness direction, and has taken the following solving means.

That is, according to a first aspect of the present invention, the first insulating member is provided with a leaf-spring-shaped conductive member, the second insulating member is provided with an opening penetrating in a thickness direction, and the light emitting module is provided with: The second insulating member is movably held between a first position in which it contacts the peripheral edge of the opening and a second position that is separated from the peripheral edge of the opening against the biasing force of the conductive member. It is configured to do.

In the first invention, the light emitting module held between the first insulating member and the second insulating member is movable between the first position and the second position. The first position is a position where the light emitting module abuts on the peripheral edge of the opening in the second insulating member. The second position is a position where the light emitting module is separated from the peripheral edge of the opening against the biasing force of the conductive member.

As a result, it is possible to prevent the spring performance of the leaf-spring-shaped conductive member from deteriorating.

Specifically, when the leaf spring-shaped conductive member is elastically deformed and pressed against the light emitting module from the time of temporary assembly before the final assembly of the product, during storage or transportation after temporary assembly, The conductive member may be loaded and the conductive member may be plastically deformed.

On the other hand, in the present invention, if the light emitting module is arranged at the first position during the temporary assembly, it is possible to suppress the load on the conductive member.

Further, by disposing the light emitting module at the second position during final assembly, it is possible to electrically connect the light emitting module and the conductive member while suppressing deterioration of the spring performance of the conductive member.

In a second aspect based on the first aspect, a gap is provided between the light emitting module arranged at the first position and the conductive member.

In the second aspect, by providing a gap between the light emitting module arranged at the first position and the conductive member, it is possible to prevent the conductive member from being plastically deformed by applying a load during temporary assembly.

In a third aspect based on the first aspect, the light emitting module arranged at the first position and the conductive member are in contact with each other.

In the third invention, the light emitting module arranged at the first position is brought into contact with the conductive member. As a result, it is possible to prevent dust and water from entering between the electrode portion of the light emitting module and the contact portion of the conductive member, and thereby preventing the electrode portion from being soiled or corroded.

A fourth aspect of the present invention is the light emitting device according to any one of the first to third aspects, wherein the first insulating member is provided with an insulating spring, and the insulating spring is arranged at the first position. While a gap is provided between the module and the module, the light emitting module arranged at the second position is pressed in the thickness direction.

In the fourth invention, a gap is provided between the light emitting module arranged at the first position and the insulating spring. Further, the light emitting module arranged at the second position is pressed in the thickness direction by the insulating spring.

Thus, during the temporary assembly, the biasing force of the insulating spring is not applied to the light emitting module arranged at the first position. Moreover, at the time of final assembly, the light emitting module arranged at the second position is pressed in the thickness direction by an insulating spring. Thus, the light emitting module can be held by the biasing force of the conductive member and the biasing force of the insulating spring.

A fifth invention comprises the holder according to any one of the first to fourth inventions, a light emitting module held by the holder, and a base for fixing the holder, Is a lighting fixture provided with a push-out portion that moves into the opening and pushes the light emitting module toward the conductive member to move the light emitting module to the second position.

In the fifth aspect, the pushing unit is provided on the base for fixing the holder. The push-out portion moves into the opening of the holder and pushes the light emitting module toward the conductive member to move the light emitting module to the second position.

Accordingly, when the work of fixing the holder to the base is performed, the light emitting module can be moved to the second position by the push-out portion of the base, and the workability of final assembly is improved.

According to the present invention, it is possible to prevent the spring performance of the leaf-spring-shaped conductive member from deteriorating.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following description of the preferred embodiments is merely an example in essence, and is not intended to limit the present invention, its application, or its use.

As shown in FIG. 1, the lighting fixture 10 includes a fixture body 11, a holder 15, and a light emitting module 40 held by the holder 15.

The instrument body 11 includes a light emitting portion 12 that emits light, a housing portion 13 that houses the holder 15, and a fin portion 14 that dissipates heat generated in the light emitting module 40.

The emission part 12 is formed of a cylindrical member. The inner surface of the emitting portion 12 is inclined so as to gradually spread radially outward toward the opening at the emitting end. The inner surface of the emitting portion 12 constitutes a reflecting surface that reflects the light emitted from the light emitting module 40.

A metal layer may be formed on the inner surface of the emitting portion 12 by vapor deposition, plating, sputtering or the like in order to increase the reflectance of light, or may be mirror-finished by polishing or the like. Further, a white coating film containing a white pigment may be formed on the inner surface of the emitting portion 12.

The holder 15 holds the light emitting module 40. The light emitting module 40 has, for example, a COB (Chip on Board) type light emitting section 42 mounted on a square substrate 41. The light emitting unit 42 is configured by, for example, an LED (Light Emitting Diode).

The holder 15 is housed in the housing part 13 in a posture in which the light emitting part 42 of the light emitting module 40 is directed toward the opening of the emitting part 12.

The fin portion 14 is in thermal contact with the light emitting module 40. The heat generated in the light emitting module 40 is radiated from the fin portion 14.

As shown in FIGS. 2 to 4, the holder 15 has a first insulating member 20 and a second insulating member 30. The first insulating member 20 and the second insulating member 30 are made of a resin material. The first insulating member 20 and the second insulating member 30 hold the light emitting module 40 in a state of being sandwiched in the thickness direction. The holder 15 is screwed to the base 50.

The first insulating member 20 includes a first main body portion 21, a leaf spring-shaped conductive member 45, and an insulating spring 25. The first main body 21 is formed in a window frame shape having an opening in the center. The light emitting portion 42, the wiring portion 43, and the electrode portion 44 of the light emitting module 40 are exposed from the central opening of the first main body portion 21.

Engagement holes 22 are formed in the left and right side walls of the first main body portion 21. An engaging claw 34 of a second insulating member 30 described later is engaged with the engaging hole 22. The first body portion 21 is provided with an electric wire insertion hole 23 for inserting an electric wire (not shown).

The conductive member 45 is a so-called quick-connect terminal, and has a leaf spring portion 46, a terminal body portion 47, and a wire holding portion 48. The leaf spring portion 46, the terminal main body portion 47, and the electric wire holding portion 48 are formed by bending or cutting and bending one plate-shaped metal (for example, a copper plate). The conductive members 45 are arranged at the upper left corner and the lower right corner of the first main body 21 in FIG.

The leaf spring portion 46 projects into the central opening of the first body portion 21. A contact portion 46a is provided at the tip of the leaf spring portion 46. The contact portion 46a is in electrical contact with the electrode portion 44 of the light emitting module 40. The leaf spring portion 46 elastically deforms to press the light emitting module 40 toward the base 50.

The terminal main body 47 is formed in a concave shape in cross section having an opening at the top (see FIG. 4 ). The terminal main body portion 47 is arranged inside the first main body portion 21.

The electric wire holding portion 48 is formed by bending a part of the side wall of the terminal main body portion 47. The electric wire holding portion 48 holds the electric wire (not shown) inserted from the electric wire insertion hole 23 by sandwiching the electric wire with the terminal main body portion 47.

In this way, the holder 15 fixes the light emitting module 40 to the base 50 in a state where the conductive member 45 and the light emitting module 40 are electrically connected. Further, the holder 15 supplies electric power supplied from an electric wire (not shown) to the light emitting module 40 via the conductive member 45.

An insulating spring 25 is provided on the first body portion 21. The insulating springs 25 are arranged at the upper left corner and the lower right corner in FIG. 3, and project into the central opening of the first main body portion 21. The insulating spring 25 elastically deforms to press the light emitting module 40 toward the base 50 side.

The first body portion 21 is provided with boss portions 24 at the upper left corner and the lower right corner in FIG. The boss portion 24 has a through hole 24a through which the screw 16 is inserted. The holder 15 is fixed to the base 50 by screwing the boss portion 24 to the base 50.

The light emitting module 40 includes a substrate 41 and a light emitting unit 42 provided on the surface of the substrate 41. The substrate 41 is composed of a rectangular flat plate. The substrate 41 is preferably made of a material having high thermal conductivity, for example, a ceramic substrate.

The light emitting part 42 is formed in a round shape. A pair of electrode portions 44 is arranged on the surface of the substrate 41. The light emitting portion 42 and the electrode portion 44 are electrically connected by the wiring portion 43. Then, electric power for causing the light emitting section 42 to emit light is supplied from the conductive member 45 via the electrode section 44 and the wiring section 43.

The second insulating member 30 has a second body portion 31. The second main body 31 is provided with an opening 32 penetrating in the thickness direction, and is formed in a window frame shape having an opening at the center. The peripheral portion of the opening 32 of the second main body portion 31 constitutes a support portion 33 that supports the lower surface of the light emitting module 40.

Engaging claws 34 are provided on the left and right side walls of the second main body 31. The first insulating member 20 and the second insulating member 30 are brought into a temporary assembly state by engaging the engaging claw 34 with the engaging hole 22. The light emitting module 40 is held in a state of being sandwiched between the first insulating member 20 and the second insulating member 30.

The holder 15 is fixed to the base 50 after the temporary assembly state. Specifically, a screw hole (not shown) is formed in the base 50, and the holder 15 is fixed to the base 50 by screwing the boss portion 24 of the first insulating member 20 to the base 50. ..

The base 50 is composed of a rectangular metal member. An accommodating recess 51 for accommodating the support portion 33 of the second insulating member 30 is formed on the upper surface of the base 50. When the support portion 33 enters the accommodation recess 51, the light emitting module 40 supported by the support portion 33 is placed on the upper surface of the base 50. That is, the portion of the base 50 surrounded by the housing recess 51 constitutes the pushing portion 52 that pushes the light emitting module 40 away from the support portion 33.

A heat dissipation grease 53 is applied between the base 50 and the light emitting module 40. The base 50 functions as a heat sink that diffuses the heat of the light emitting module 40. Thereby, the heat generated in the light emitting module 40 can be efficiently released.

By the way, when the leaf spring-shaped conductive member 45 is elastically deformed and pressed against the light emitting module 40 from the time of temporary assembly which is a stage before final assembly of the product, during storage or transportation after temporary assembly. The conductive member 45 may be loaded and the leaf spring portion 46 of the conductive member 45 may be plastically deformed.

Therefore, in the present embodiment, by devising the shapes of the holder 15 and the base 50, the spring performance of the leaf spring portion 46 of the conductive member 45 is prevented from deteriorating.

Specifically, as shown in FIGS. 4 to 6, the light emitting module 40 held between the first insulating member 20 and the second insulating member 30 has a first position (see FIG. 4) and a second position. (See FIG. 6).

The first position is a position where the light emitting module 40 comes into contact with the support portion 33 of the second insulating member 30. The second position is a position where the light emitting module 40 separates from the support portion 33 of the second insulating member 30 against the biasing force of the leaf spring portion 46 of the conductive member 45.

As shown in FIG. 4, at the first position, the contact portion 46 a of the leaf spring portion 46 is in contact with the electrode portion 44 of the light emitting module 40. As a result, it is possible to prevent dust and water from entering between the electrode portion 44 of the light emitting module 40 and the contact portion 46a of the conductive member 45, and to prevent the electrode portion 44 from being soiled or corroded. At the first position, a gap may be provided between the contact portion 46a of the leaf spring portion 46 and the electrode portion 44 of the light emitting module 40.

Here, when the light emitting module 40 is in the first position, the leaf spring portion 46 is hardly elastically deformed. Therefore, even if a load is applied to the leaf spring portion 46 during storage or transportation after temporary assembly, the leaf spring portion 46 is only deformed in the elastic region and is less likely to be plastically deformed.

In addition, at the first position, a gap is provided between the insulating spring 25 of the first insulating member 20 and the light emitting module 40. That is, at the time of temporary assembly, the urging force of the insulating spring 25 is not applied to the light emitting module 40 arranged at the first position.

As shown in FIG. 5, when the temporarily assembled holder 15 is placed on the base 50, the push-out portion 52 of the base 50 enters through the opening 32 of the second insulating member 30. Since the heat radiating grease 53 is applied to the upper surface of the pushing portion 52, the heat radiating grease 53 spreads radially between the lower surface of the light emitting module 40 and the upper surface of the pushing portion 52. At this time, the light emitting module 40 remains in the first position.

In the state shown in FIG. 5, a gap is provided between the boss portion 24 of the holder 15 and the base 50. Therefore, the holder 15 is fixed to the base 50 by screwing the boss portion 24 of the first insulating member 20 to the base 50 with the screw 16.

As shown in FIG. 6, when the holder 15 is fixed to the base 50, the push-out portion 52 of the base 50 pushes the light emitting module 40 toward the plate spring portion 46. As a result, the light emitting module 40 moves to the second position away from the support portion 33 of the second insulating member 30 against the biasing force of the leaf spring portion 46.

At the second position, the leaf spring portion 46 of the conductive member 45 and the insulating spring 25 are elastically deformed to press the light emitting module 40 toward the base 50 side. Accordingly, the pressing force for extending the heat dissipation grease 53 between the light emitting module 40 and the base 50 can be secured by the biasing force of the leaf spring portion 46 of the conductive member 45 and the biasing force of the insulating spring 25. ..

The insulating spring 25 also functions as an interference member for preventing the fastening force when the holder 15 is screwed to the base 50 from being directly transmitted to the light emitting module 40.

As described above, in the holder 15 according to the present embodiment, by placing the light emitting module 40 at the first position during the temporary assembly, it is possible to prevent the leaf spring portion 46 of the conductive member 45 from being loaded.

Further, by disposing the light emitting module 40 at the second position during the final assembly, the light emitting module 40 and the conductive member 45 are electrically connected while suppressing the deterioration of the spring performance of the leaf spring portion 46 of the conductive member 45. be able to.
