Conventionally, there is known a configuration in which a light source substrate and a power supply substrate are separated and an LED element and a circuit element are mounted on separate substrates. In this case, the light source board and the power supply board are individually fixed at predetermined positions of the instrument body and electrically connected by electric wires such as harnesses. As a result, the LED element and the circuit element provided on the separate substrates are electrically connected.

In recent years, in lighting equipment, it has been studied to integrally configure a light source substrate and a power supply substrate (see, for example, Patent Document 1). That is, a configuration in which the LED element and the circuit element are mounted on the same substrate is being studied. In this case, the LED element and the circuit element provided on the same substrate are electrically connected by wiring formed on the substrate in a pattern of a predetermined shape. For this reason, parts such as harnesses are not required compared to the case where the light source board and the power supply board are separated, so that the cost of parts can be reduced and the man-hours for assembling the lighting equipment (such as routing and connecting the harness) are simplified. The manufacturing cost can be reduced by the introduction.

[Connecting member]
As shown in FIG. 2, the connecting member 30 electrically connects the first conductive portion 13 of the light source module 10 and the second conductive portion 23 of the power supply module 20. The connecting member 30 is arranged between the first board 11 of the light source module 10 and the second board 21 of the power supply module 20. Specifically, the connecting member 30 is sandwiched between the first substrate 11 and the second substrate 21 together with the spacer 40. That is, the first substrate 11 and the second substrate 21 are arranged apart by the height of the connecting member 30 and the spacer 40.

The connecting member 30 has a connecting conductor 31 having an elastic force and a holding body 32 for holding the connecting conductor 31.

The connecting conductor 31 is in contact with the first conductive portion 13 provided on the first substrate 11 and the second conductive portion 23 provided on the second substrate 21. Specifically, the connecting conductor 31 is in contact with the first conductive portion 13 and the second conductive portion 23 in a state of receiving a pressing force from the first substrate 11 and the second substrate 21.

As shown in FIGS. 3B and 4, the connecting conductor 31 is provided one-to-one with the three first conductive portions 13 and the three second conductive portions 23. Therefore, three connecting conductors 31 are provided.

In the present embodiment, each connecting conductor 31 is a leaf spring having a spring property. That is, the connecting conductor 31 has a property of being deformed when an external force is applied to the connecting conductor 31 and returning to the original state when the external force is released. That is, the connecting conductor 31 has a spring restoring force as an elastic force. For example, the connecting conductor 31 is a conductive plate made of sheet metal, and can be formed by pressing a metal plate having a predetermined shape.

Specifically, as shown in FIGS. 3A and 3B, the connecting conductor 31 which is a leaf spring extends in the same direction as the first plate portion 31a and the first plate portion 31a. It has a second plate portion 31b and a third plate portion 31c that connects the first plate portion 31a and the second plate portion 31b. In the present embodiment, the second plate portion 31b faces the first plate portion 31a. That is, the first plate portion 31a and the second plate portion 31b overlap each other when viewed in a plan view.

Further, the connecting member 30 has a double spring structure. Therefore, when the connecting member 30 is fixed to the first substrate 11 and the second substrate 21, the first plate portion 31a is elastically deformed in contact with the first conductive portion 13 of the first substrate 11 and is elastically deformed. The two-plate portion 31b is elastically deformed in contact with the second conductive portion 23 of the second substrate 21. That is, the first plate portion 31a is in elastic contact with the first conductive portion 13, and the second plate portion 31b is in elastic contact with the second conductive portion 23.

The holding body 32 is a housing for accommodating the connecting conductor 31. The holding body 32 has a recess having a U-shaped cross section. The holding body 32 holds the connecting conductor 31 by accommodating the connecting conductor 31 in the recess of the holding body 32.

Specifically, the holding body 32 faces the first substrate 11 and has a plate-shaped first holding portion 32a that holds the first plate portion 31a on the inner surface, and the holding body 32 faces the second substrate 21 and the second plate portion. It has a plate-shaped second holding portion 32b that holds 31b on the inner surface, and a third holding portion 32c that supports the first holding portion 32a and the second holding portion 32b.

The first holding portion 32a is formed with a substantially rectangular first opening 32a1 which is a through hole penetrating the first holding portion 32a. The second holding portion 32b is formed with a substantially rectangular second opening 32b1, which is a through hole penetrating the second holding portion 32b.

The first plate portion 31a of the connecting conductor 31 has a first contact portion 31a1 that comes into contact with the first conductive portion 13 provided on the first substrate 11 when the first plate portion 31a is elastically deformed. The contact portion between the first contact portion 31a1 and the first conductive portion 13 becomes the first contact. The first contact portion 31a1 comes into contact with the first conductive portion 13 via the first opening 32a1 of the first holding portion 32a. As shown in FIG. 3A, the first contact portion 31a1 is formed so as to be curved so as to project outward from the first opening portion 32a1.

Further, the second plate portion 31b of the connecting conductor 31 has a second contact portion 31b1 that comes into contact with the second conductive portion 23 provided on the second substrate 21 when the second plate portion 31b is elastically deformed. The contact portion between the second contact portion 31b1 and the second conductive portion 23 is the second contact. The second contact portion 31b1 comes into contact with the second conductive portion 23 via the second opening 32b1 of the second holding portion 32b. Like the first contact portion 31a1, the second contact portion 31b1 is formed so as to be curved so as to project outward from the second opening portion 32b1.

As shown in FIG. 3B, the holding body 32 is provided with a first protrusion 32d. The first protrusion 32d is provided on the surface of the first holding portion 32a on the first substrate 11 side. A flange portion is formed at the tip portion of the first protrusion 32d, and by inserting the first protrusion 32d into the first through hole 11d of the first substrate 11 and pushing it in, the tip portion of the first protrusion 32d is formed. Is locked to the first substrate 11.

Further, the holding body 32 is provided with a second protrusion 32e. The second protrusion 32e is provided on the surface of the second holding portion 32b on the second substrate 21 side. A flange portion is formed at the tip portion of the second protrusion 32e, and by inserting the second protrusion 32e into the second through hole 21d of the second substrate 21, the tip of the second protrusion 32e is inserted. The portion is locked to the second substrate 21.

The first protrusion 32d and the second protrusion 32e are, for example, locking supports, and by pushing the first protrusion 32d and the second protrusion 32e into the first through hole 11d and the second through hole 21d by snap-in, the first protrusion 32d and the second protrusion 32e are for example. The flange portions of the first protrusion 32d and the second protrusion 32e can be hooked on the surfaces of the first substrate 11 and the second substrate 21. As a result, the tip of the second protrusion 32e can be locked to the second substrate 21.

Although the connecting member 30 is schematically shown in FIGS. 3 and 4, the connecting member 30 may be specifically configured as shown in FIGS. 5A to 5C. FIG. 5A is a perspective view of the connecting member 30 according to the embodiment of the first embodiment. FIG. 5B is a cross-sectional view of the connecting member 30 according to the embodiment of the first embodiment. FIG. 5C is a perspective view of the connecting conductor 31 in the connecting member 30 according to the embodiment of the first embodiment.

In the connecting member 30 in this embodiment, as shown in FIG. 5B, the protrusion 32c1 is formed on the third holding portion 32c of the holding body 32. The number of protrusions 32c1 is the same as the number of connecting conductors 31 (three in this embodiment). Further, as shown in FIG. 5C, a through hole 31c1 is formed in the third connecting conductor 31c of each connecting conductor 31. Then, by inserting the protrusion 32c1 of each holding body 32 into the through hole 31c1 of each connecting conductor 31 and locking the protrusion 32c1 to the through hole 31c1, each connecting conductor 31 is fixed to the holding body 32. There is.

As shown in FIG. 5A, in the connecting member 30 in this embodiment, the second protrusion 32e of the holding body 32 does not have a locking support structure, but like the first protrusion 32d, it has a locking support structure. It may be.

[Connection method]
Next, a method of connecting the light source module 10 and the power supply module 20 will be described with reference to FIGS. 2 to 4.

First, the connecting member 30 is arranged so as to correspond to the first connecting region 11c of the first substrate 11 and the second connecting region 21c of the second substrate 21, and the first projection portion 32d of the holding body 32 of the connecting member 30 is arranged. Is fitted into the first through hole 11d of the first substrate 11, and the second protrusion 32e of the holding body 32 of the connecting member 30 is fitted into the second through hole 21d of the second substrate 21. As a result, the first substrate 11 and the second substrate 21 are connected by the connecting member 30. That is, the light source module 10 and the power supply module 20 are temporarily fixed (temporarily fixed) to the connecting member 30.

At the time of this temporary fixing, the first conductive portion 13 of the first substrate 11 and the connecting conductor 31 (first plate portion 31a) of the connecting member 30 may or may not be in contact with each other. .. Similarly, the second conductive portion 23 of the second substrate 21 and the connecting conductor 31 (second plate portion 31b) of the connecting member 30 may or may not be in contact with each other.

Next, the spacer 40 is arranged between the first substrate 11 and the second substrate 21, and the first substrate 11 and the second substrate 21 are screwed together by the screws 50.

Specifically, four spacers 40 are arranged between the first substrate 11 and the second substrate 21. At this time, each spacer 40 has the first substrate 11 and the second substrate 21 so that the through hole 41 coincides with the first screw hole 11e of the first substrate 11 and the second screw hole 21e of the second substrate 21. It is inserted in between.

Then, the shaft portion of the screw 50 is inserted in the order of the second screw hole 21e (second board 21), the through hole 41 (spacer 40), and the first screw hole 11e (first board 11), and the first board 11 and The first substrate 11 and the second substrate 21 are fixed by the screws 50 with the connecting member 30 and the spacer 40 sandwiched between the second substrate 21.

In the present embodiment, a screw hole into which the screw 50 is screwed is formed in the instrument main body 60, and by screwing the screw 50 into the screw hole of the instrument main body 60, the first substrate 11 and the second substrate 21 are the instrument. It is fastened together with the main body 60. Therefore, in this case, the first screw hole 11e of the first substrate 11 and the second screw hole 21e of the second substrate 21 may be drilled holes. Further, when the screw 50 is not screwed into the instrument main body 60, the second screw hole 21e may be used as a tap hole.

In this way, the first board 11 and the second board 21 are fixed by the screws 50 with the connecting member 30 sandwiched between them, so that the light source module 10 and the power supply module 20 are integrated together with the connecting member 30 to form the instrument main body. It is fixed at 60.

At this time, the connecting member 30 is sandwiched between the first substrate 11 and the second substrate 21, so that the light source module 10 and the power supply module 20 and the connecting member 30 are not only mechanically connected but also electrically connected. Will be done. Specifically, when the connecting member 30 is sandwiched between the first substrate 11 and the second substrate 21, the connecting conductor 31 of the connecting member 30 receives a pressing force from the first substrate 11 and the second substrate 21. As a result, the first conductive portion 13 of the first substrate 11 and the first plate portion 31a of the connecting conductor 31 come into contact with each other to conduct conduction, and the second conductive portion 23 of the second substrate 21 and the connecting conductor 31 are second. 2 The plate portion 31b is in contact with each other to conduct conduction.

That is, the connecting conductor 31 is in contact with the first conductive portion 13 and the second conductive portion 23 in a state where the pressing force is received from the first substrate 11 and the second substrate 21. In this case, since the connecting conductor 31 has an elastic force, the connecting conductor 31 exerts stress in the Z-axis direction on the first substrate 11, the second substrate 21, and the connecting member 30 by tightening the screw 50. It can be absorbed by elastically deforming.

Further, in the present embodiment, the spacer 40 is arranged between the first substrate 11 and the second substrate 21. As a result, the distance between the first substrate 11 and the second substrate 21 is regulated by the spacer 40, so that even if the screws 50 are tightened too much, the first substrate 11 and the second substrate 21 are separated by the height of the spacer 40. Only approach up to. As a result, it is possible to prevent the connecting member 30 from being excessively pinched by the first substrate 11 and the second substrate 21 so as to be deformed or damaged.

When the screw 50 is tightened, the connecting conductor 31 is in contact with the first conductive portion 13 and the second conductive portion 23, and the holding body 32 is not in contact with the first substrate 11 and the second substrate 21. In order to secure the above, the height of the spacer 40 is higher than the height of the holding body 32 and lower than the height of the connecting conductor 31 when no pressing force is applied to the connecting conductor 31. It is good to do it.

Further, the connection method between the light source module 10 and the power supply module 20 is not limited to the above connection method (first connection method). For example, as a second connection method for connecting the light source module 10 and the power supply module 20, first, the first substrate 11 is fixed to the instrument main body 60, the connection member 30 and the spacer 40 are arranged on the first substrate 11, and further. A method of arranging the second substrate 21 on the second substrate 21 and screwing it with the screw 50 may be used.

In this case, specifically, the light source module 10 and the power supply module 20 can be connected as follows. A second connection method for connecting the light source module 10 and the power supply module 20 will be described with reference to FIGS. 2 to 4.

First, the light source module 10 is attached to the instrument body 60. Specifically, the first substrate 11 of the light source module 10 is fixed to the instrument main body 60 by a fixing member such as a screw or caulking.

Next, the connecting member 30 is positioned and the connecting member 30 is temporarily fixed to the light source module 10. Specifically, the connecting member 30 is arranged so as to correspond to the first connection region 11c of the first substrate 11, and the first protrusion 32d of the holding body 32 of the connecting member 30 is snapped in to the first substrate 11. The connecting member 30 is temporarily fixed to the first substrate 11 by fitting it into the first through hole 11d. That is, the connection member 30 is temporarily fixed to the first substrate 11 by locking the tip of the first protrusion 32d to the first substrate 11. As a result, the connecting member 30 can be prevented from being laterally displaced with respect to the first substrate 11, and the connecting member 30 can be positioned laterally with respect to the first substrate 11, and the connecting member 30 can be positioned with respect to the first substrate 11. It is possible to prevent the connecting member 30 from floating due to the spring reaction force of the connecting conductor 31 when the 30 is placed.

The temporary fixing of the connecting member 30 is not limited to a structure in which the tip of the first protrusion 32d is locked to the first substrate 11 (locking support structure), but is a structure in which the first protrusion 32d is simply lengthened. You may. That is, the connecting member 30 may not be laterally displaced from the first substrate 11 until the second substrate 21 is finally fixed. Further, although the connecting member 30 is positioned in this step, the positioning of the connecting member 30 is required even after the final fixing. This is because if the connecting member 30 is not positioned, the connecting member 30 is held only by the frictional force due to the pressing of the two boards of the first substrate 11 and the second substrate 21, and the connecting member 30 is held in an unstable state. Because it will be done.

Next, the power supply module 20 is temporarily fixed to the connection member 30 temporarily fixed to the first substrate 11. Specifically, the second board 21 is arranged so that the second connection region 21c of the second board 21 of the power supply module 20 corresponds to the connection member 30, and the second projection portion of the holding body 32 of the connection member 30 is arranged. The second substrate 21 is temporarily fixed to the connecting member 30 so that the 32e is fitted into the second through hole 21d of the second substrate 21 by snap-in. As a result, the connecting member 30 can be prevented from being laterally displaced with respect to the second substrate 21, and the connecting member 30 can be positioned laterally with respect to the second substrate 21.

In this way, the first substrate 11 of the light source module 10 and the second substrate 21 of the power supply module 20 are connected by the connecting member 30. That is, both the light source module 10 and the power supply module 20 are temporarily fixed to the connecting member 30.

At the time of this temporary fixing, as described above, the first conductive portion 13 of the first substrate 11 and the connecting conductor 31 (first plate portion 31a) of the connecting member 30 may be in contact with each other. It does not have to be in contact. Similarly, the second conductive portion 23 of the second substrate 21 and the connecting conductor 31 (second plate portion 31b) of the connecting member 30 may or may not be in contact with each other. Further, the method of temporary fixing is not limited to the method of locking the tip of the first protrusion 32d to the first substrate 11 (snap-in), but the method of connecting the connecting conductor 31 and the first conductive portion 13 by soldering. May be. However, in the case of temporarily fixing only with solder, the first protrusion 32d is fitted into the first through hole 11d so that the position of the connecting member 30 does not shift laterally even after the solder connection portion is cracked. It is good to leave it.

Next, the first substrate 11 and the second substrate 21 are finally fixed. Specifically, a spacer 40 is arranged between the first substrate 11 and the second substrate 21, and the first substrate 11 and the second substrate 21 are screwed together by screws 50.

In the second connection method, the first substrate 11 is first fixed to the instrument main body 60. Therefore, the first substrate 11 and the second substrate 21 need only be fastened together with the screws 50, and the screws 50 do not have to be screwed into the instrument main body 60.

As described above, according to the first connection method and the second connection method, the light source module 10 and the power supply module 20 can be connected to each other, and at the same time, the light source module 10 and the power supply module 20 can be fixed to the instrument main body 60. Therefore, the assembly efficiency of the lighting fixture can be improved. Further, when screwing with the screw 50, the circuit cover 70 and the light source cover 80 may be fastened together using the same holes at the same time. This makes it possible to further improve the assembly efficiency of the lighting fixture.

[summary]
As described above, according to the lighting fixture 1 according to the present embodiment, the LED element 12, the first substrate 11 provided with the first conductive portion 13 electrically connected to the LED element 12, and the LED element 12 are provided. The circuit element 22 for emitting light, the second substrate 21 provided with the second conductive portion 23 electrically connected to the circuit element 22, and the first conductive portion 13 and the second conductive portion 23 are electrically connected. It includes a connecting member 30 to be connected, and the connecting member 30 has a connecting conductor 31 having an elastic force. Then, the first substrate 11 and the second substrate 21 are fixed by the screws 50 with the connecting member 30 sandwiched between them, and the connecting conductor 31 is in a state of receiving pressing force from the first substrate 11 and the second substrate 21. It is in contact with the first conductive portion 13 and the second conductive portion 23.

As described above, in the luminaire 1 according to the present embodiment, the first substrate 11 provided with the LED element 12 and the second substrate 21 provided with the circuit element 22 are separate bodies. Even if the number of varieties increases, it can be easily dealt with. That is, since the first board 11 and the second board 21 are separated, the light source module 10 and the power supply module 20 can be individually designed according to the specifications of the product, or the light source module 10 and the power supply module 20 of the standard specifications can be individually designed. By preparing a plurality of them and combining them, it is possible to easily develop a wide variety of products.

Moreover, in the lighting fixture 1 of the present embodiment, the connecting conductor 31 of the connecting member 30 is fixed to the first substrate 11 by fixing the connecting member 30 in a state of being sandwiched between the first substrate 11 and the second substrate 21. 1 The conductive portion 13 is in contact with the second conductive portion 23 of the second substrate 21. That is, the light source module 10 and the power supply module 20 are electrically connected by fixing the first board 11 and the second board 21.

This eliminates the need for electric wires such as harnesses for electrically connecting the light source module 10 and the power supply module 20, even though the first board 11 and the second board 21 are separate bodies. As in the case where the 11 and the second substrate 21 are made of the same substrate, the lighting fixture can be easily assembled.

In particular, in the present embodiment, the first substrate 11, the second substrate 21, and the instrument main body 60 are fastened together by the screws 50.

As a result, the light source module 10 and the power supply module 20 are fixed to the instrument main body 60, thereby completing the electrical connection between the light source module 10 and the power supply module 20. Therefore, the lighting fixture can be assembled more easily.

Further, in the present embodiment, when the first substrate 11 and the second substrate 21 are fixed by the screws 50, the connecting conductor 31 is first in a state of receiving pressing force from the first substrate 11 and the second substrate 21. It will come into contact with the conductive portion 13 and the second conductive portion 23. In this case, since the connecting conductor 31 has an elastic force, even if the connecting member 30 is sandwiched between the first substrate 11 and the second substrate 21 and receives the stress of the pressing force, the stress is applied to the connecting conductor. 31 can be absorbed by elastically deforming. As a result, the pressing force from the first substrate 11 and the second substrate 21 received by the connecting member 30 or the reaction force from the connecting member 30 received by the first substrate 11 and the second substrate 21 can be alleviated by the connecting conductor 31. can. Therefore, it is possible to prevent the first substrate 11, the second substrate 21, and the connecting member 30 from being damaged or deformed by stress.

As described above, in the lighting fixture 1 according to the present embodiment, the first substrate 11 (light source module 10) and the second substrate 21 (power supply module 20) are mechanically connected by screws 50 with the connecting member 30 sandwiched between them. However, it has a structure that can relieve the stress caused by tightening the screw 50.

Further, in the present embodiment, the connecting member 30 has a holding body 32 for holding the connecting conductor 31, and the connecting conductor 31 is a leaf spring.

As a result, it is possible to easily realize a connecting conductor 31 having an elastic force and having a structure in which it is in contact with both the first conductive portion 13 and the second conductive portion 23 at the same time. That is, it is possible to achieve both the electrical connection between the light source module 10 and the power supply module 20 and the relaxation of the stress applied to the first substrate 11, the second substrate 21, and the connecting member 30 by screwing. A possible connection conductor 31 can be easily realized.

Further, in the present embodiment, the connecting conductor 31, which is a leaf spring, has a first plate portion 31a, a second plate portion 31b facing the first plate portion 31a, a first plate portion 31a, and a second plate portion. It has a third plate portion 31c that connects to 31b. Further, the holding body 32 faces the first substrate 11 and holds the first plate portion 31a on the inner surface, and the holding body 32 faces the second substrate 21 and has the second plate portion 31b on the inner surface. It has a plate-shaped second holding portion 32b to be held by, and a third holding portion 32c for supporting the first holding portion 32a and the second holding portion 32b. The first holding portion 32a is formed with the first opening portion 32a1, the second holding portion 32b is formed with the second opening portion 32b1, and the first plate portion 31a is formed with the first opening portion 32a1. The second plate portion 31b has a second contact portion 31b1 that contacts the second conductive portion 23 via the second opening portion 32b1. ..

As a result, it is possible to easily realize a connecting conductor 31 having an elastic force while being held by the holding body 32 and having a structure in which the first conductive portion 13 and the second conductive portion 23 are in contact with each other at the same time.

Further, in the present embodiment, the circuit element 22 is provided on the surface (first main surface 21a) of the second substrate 21 on the first substrate 11 side. That is, at least a part of the main body of the circuit element 22 can be arranged by utilizing the space region between the first substrate 11 and the second substrate 21.

As a result, the circuit element 22 can be arranged by utilizing the space between the first substrate 11 and the second substrate 21. Therefore, the total height of the light source module 10 and the power supply module 20 can be lowered as compared with the case where the circuit element 22 is arranged on the second main surface 21b of the second substrate 21.

Further, in the present embodiment, the second main surface 21b, which is the surface of the second substrate 21 opposite to the surface on the first substrate 11 side, is a solder surface. The second conductive portion 23 is a lead whose both ends penetrate the second substrate 21 from the surface on the first substrate 11 side toward the second main surface 21b which is the solder surface, and one end of the lead is a solder surface. The second main surface 21b is solder-bonded, and the other end of the lead penetrates the second substrate 21.

As a result, not only the connecting conductor 31 but also the second conductive portion 23 has elastic force. Therefore, the stress applied to the first substrate 11, the second substrate 21, and the connecting member 30 can be more easily relieved.

Further, in the present embodiment, a plurality of second conductive portions 23 are provided for one connecting conductor 31.

As a result, even when the second conductive portion 23 is as thin as a lead, it is possible to suppress the occurrence of poor contact with the connecting conductor 31. That is, if the second conductive portion 23 is elongated and one like a lead, the position of the connecting conductor 31 and the second conductive portion 23 is displaced (for example, the Y axis) when the light source module 10 and the power supply module 20 are connected. When lateral displacement in the direction occurs), the connecting conductor 31 and the second conductive portion 23 may not come into contact with each other, and conduction may not be required. On the other hand, by providing a plurality of second conductive portions 23 for one connecting conductor 31, even if the connecting conductor 31 and the second conductive portion 23 are displaced from each other, the connecting conductor is connected. The contact state between the 31 and the second conductive portion 23 can be maintained. That is, at least one of the plurality of second conductive portions 23 may be in contact with the connecting conductor 31.

Further, in the present embodiment, the first conductive portion 13 is a metal wiring formed in a predetermined pattern on the surface of the first substrate 11 on the second substrate 21 side.

As a result, when forming another metal wiring formed on the first substrate 11, the metal wiring of the first conductive portion 13 can be simultaneously patterned and formed.

Further, the luminaire 1 in the present embodiment further includes a spacer 40 sandwiched between the first substrate 11 and the second substrate 21. The shaft portion of the screw 50 penetrates the spacer 40.

As a result, the screw 50 can be provided by utilizing the space for arranging the spacer 40 while ensuring the space between the first substrate 11 and the second substrate 21 with the spacer 40.

Further, in the present embodiment, FIGS. 5A to 5A are specific examples of the connecting member 30 for electrically connecting the first conductive portion 13 of the first substrate 11 and the second conductive portion 23 of the second substrate 21. Although the connecting member 30 having the configuration shown in 5C is used, the present invention is not limited to this. Hereinafter, another embodiment of the connecting member 30 will be described as a modified example of the first embodiment.

(Modification 1 of Embodiment 1)
First, the first modification of the first embodiment will be described with reference to FIGS. 6A to 6C. FIG. 6A is a perspective view of the connecting member 30A according to the first modification of the first embodiment. FIG. 6B is a cross-sectional view of the connecting member 30A. FIG. 6C is a perspective view of the connecting conductor 31A in the connecting member 30A.

As shown in FIGS. 6A to 6C, the connecting member 30A in this modification has a double spring structure like the connecting member 30 shown in FIGS. 5A to 5C. That is, when the connecting member 30A is fixed to the first substrate 11 and the second substrate 21, the first plate portion 31a of the connecting conductor 31A has the first contact portion 31a1 as the first conductive portion 13 of the first substrate 11. The second plate portion 31b of the connecting conductor 31A is elastically deformed in a state where the second contact portion 31b1 is in contact with the second conductive portion 23 of the second substrate 21.

Further, as shown in FIG. 6C, the connecting conductor 31A of the connecting member 30A in this modification is a first reinforcing plate as a reinforcing portion for increasing the rigidity of the connecting conductor 31A to reinforce the connecting conductor 31A. It has 31d and a second reinforcing plate 31e. The first reinforcing plate 31d is connected to the third plate portion 31c so as to surround the first plate portion 31a. The second reinforcing plate 31e is connected to the third plate portion 31c so as to surround the second plate portion 31b.

(Modification 2 of Embodiment 1)
Next, the second modification of the first embodiment will be described with reference to FIGS. 7A to 7C. FIG. 7A is a perspective view of the connecting member 30B according to the second modification of the first embodiment. FIG. 7B is a cross-sectional view of the connecting member 30B. FIG. 7C is a perspective view of the connecting conductor 31B in the connecting member 30B.

As shown in FIGS. 7A to 7C, the connecting member 30B in this modification has a one-sided spring structure unlike the connecting member 30 shown in FIGS. 5A to 5C. That is, when the connecting member 30B is fixed to the first substrate 11 and the second substrate 21, only one of the first plate portion 31a and the second plate portion 31b of the connecting conductor 31B is elastically deformed.

In this modification, when the connecting member 30B is fixed to the first substrate 11 and the second substrate 21, the first plate portion 31a of the connecting conductor 31B does not elastically deform to the extent that it has a spring restoring force. It comes into contact with the first conductive portion 13 of the first substrate 11. On the other hand, the second plate portion 31b of the connecting conductor 31B is elastically deformed so as to have a spring restoring force and comes into contact with the second conductive portion 23 of the second substrate 21.

Further, as shown in FIG. 7C, the connecting conductor 31B of the connecting member 30B in the present modification has a reinforcing plate 31e as a reinforcing portion for reinforcing the connecting conductor 31B, similarly to the connecting member 30A in the modification 1. The reinforcing plate 31e is connected to the third plate portion 31c so as to surround the second plate portion 31b.

(Modification 3 of Embodiment 1)
Next, a modification 3 of the first embodiment will be described with reference to FIGS. 8A to 8C and FIG. FIG. 8A is a perspective view of the connecting member 30C according to the third modification of the first embodiment. FIG. 8B is a cross-sectional view of the connecting member 30C. FIG. 8C is a perspective view of the connecting conductor 31C in the connecting member 30C. FIG. 9 is a cross-sectional view showing a portion where the first substrate 11 of the light source module 10 and the second substrate 21 of the power supply module 20 are connected by the connection member 30C.

As shown in FIGS. 8A to 8C, the connecting member 30C in this modification has a connecting conductor 31C having an elastic force and a holding body 32C holding the connecting conductor 31C. The connecting conductor 31C is a leaf spring having a spring property, and three connecting conductors 31C are provided. The connecting conductor 31C is a conductive plate made of sheet metal, and can be formed by, for example, pressing a metal plate having a predetermined shape.

The holding body 32C is a housing for accommodating the connecting conductor 31C. The holding body 32C has a concave portion having a bottomed square cylinder. The three connecting conductors 31C are housed in the recesses of the holding body 32C. The holding body 32C is formed with three through holes for exposing a part of each connecting conductor 31C.

Then, in this modification, as shown in FIG. 9, in order to temporarily fix the connecting member 30C and the first substrate 11, the connecting conductor 31C is the first conductive portion 13 and the second conductive portion 13 of the first substrate 11. It is connected to at least one of the second conductive portions 23 of the substrate 21 by soldering.

That is, in the first embodiment, when the light source module 10 and the power supply module 20 are connected by the connecting member 30, the tip of the first protrusion 32d of the connecting member 30 is engaged with the first through hole 11d of the first substrate 11. The connection member 30 and the first substrate 11 were temporarily fixed by stopping, but in this modification, when the light source module 10 and the power supply module 20 are connected by the connection member 30C, the connection member 30C and the first board are connected by soldering. Temporarily fixed to 1 substrate 11.

As shown in FIG. 9, in this modification, the connecting conductor 31C is connected to the first conductive portion 13 of the first substrate 11 by soldering.

Specifically, as shown in FIGS. 8B, 8C and 9, the connecting conductor 31C is a solder portion 311 connected to the first conductive portion 13 of the first substrate 11 by soldering, and the second substrate 21. It has a spring portion 312 that is in elastic contact with the second conductive portion 23, and a leg portion 313 that connects the solder portion 311 and the spring portion 312.

The solder portion 311 is a plate portion that comes into surface contact with the first conductive portion 13 of the first substrate 11. The contact portion between the solder portion 311 and the first conductive portion 13 becomes the first contact. In this modification, a pair of solder portions 311 is formed. Specifically, the solder portion 11 is formed so as to be bent outward from each of the pair of leg portions 313 so as to be exposed from the opening of the holding body 32C.

The spring portion 312 has a contact portion 312a that comes into contact with the second conductive portion 23 of the second substrate 21, and a pair of bending portions 312b for spring-deforming the connecting conductor 310. As shown in FIGS. 8A and 8B, the spring portion 312 (contact portion 312a) comes into contact with the second conductive portion 23 via the through hole 31C1 formed in the holding body 32C. The contact portion between the contact portion 312a of the spring portion 312 and the second conductive portion 23 becomes the second contact.

A pair of leg portions 313 are formed on both sides of the spring portion 312. Specifically, the pair of leg portions 313 are connected to the pair of bent portions 312b of the spring portion 312. The movement of the leg portion 313 is restricted by the holding body 32C. Specifically, the leg portion 313 is restricted from moving by coming into contact with the inner surface of the holding body 32C.

As described above, in this modification, when the light source module 10 and the power supply module 20 are connected by the connecting member 30C, the connecting member 30C and the first substrate 11 are temporarily fixed by soldering.

At this time, in the connecting member 30 shown in FIGS. 5A to 5C, the first contact between the connecting conductor 31 (first contact portion 31a1) and the first conductive portion 13 of the first substrate 11 is temporarily fixed by soldering. Since the pressure from the second contact between the second substrate 21 and the connecting conductor 31 (second contact portion 31b1) continues to be applied to the solder portion, there is a possibility that cracks may be formed in the solder portion.

Even in the connecting member 30C in this modification, since the first contact between the connecting conductor 31C (solder portion 311) and the first conductive portion 13 of the first substrate 11 is temporarily fixed by solder, the connecting conductor 31C (spring). When the second conductive portion 23 of the second substrate 21 comes into elastic contact with the portion 312), the leg portion 313 of the connecting conductor 31C tends to spread outward.

However, in this modification, the movement of the leg portion 313 of the connecting conductor 31C is restricted by the holding body 32C. As a result, even if the first contact between the connecting conductor 31C (solder portion 311) and the first conductive portion 13 of the first substrate 11 is temporarily fixed by soldering, the leg portion 313 of the connecting conductor 31C is outward. Since it does not spread, the force in the direction of peeling from the first substrate 11 does not act on the solder portion 311 soldered to the first conductive portion 13 of the first substrate 11. Therefore, it is possible to prevent cracks from entering the solder connection portion between the connecting conductor 31C (solder portion 311) and the first conductive portion 13 of the first substrate 11. Further, even if the solder portion 311 is cracked by pressing, the position of the connecting conductor 31C does not shift in the lateral direction, and the pressing on the first substrate 11 continues to be applied, so that stable electrical connection is continued.

In this modification, the connecting conductor 31C is connected to the first conductive portion 13 of the first substrate 11 by soldering, but the present invention is not limited to this. For example, the connecting conductor 31C may be connected to the second conductive portion 23 of the second substrate 21 by soldering.

(Modified Example 4 of Embodiment 1)
Next, a modification 4 of the first embodiment will be described with reference to FIGS. 10A to 10C. FIG. 10A is a perspective view of the connecting member 30D according to the fourth modification of the first embodiment. FIG. 10B is a cross-sectional view of the connecting member 30D. FIG. 10C is a perspective view of the connecting conductor 31D in the connecting member 30D.

As shown in FIGS. 10A to 10C, the connecting member 30D in the present modification is temporarily fixed to the connecting member 30D and the first substrate 11 in the same manner as the connection member 30C (FIGS. 8A to 8C) in the modification 3. Is done by soldering.

The difference between the connecting member 30D in the present modification and the connecting member 30C in the modification 3 is the shape of the connecting conductor 31D. Specifically, in the connecting member 30C in the modified example 3, the bent portion 312b of the spring portion 312 of the connecting conductor 31C was present in the holding body 32D, whereas in the connecting member 30D in the present modified example, the bent portion 312b was present. The bent portion 312b of the spring portion 312 of the connecting conductor 31D exists outside the holding body 32D. Specifically, the bent portion 312b of the spring portion 312 of the connecting conductor 31D is formed so as to be bent outward from each of the pair of leg portions 313 so as to be exposed from the through hole 32D1 of the holding body 32D.

Further, in the connecting member 30D in the present modification, the movement of the leg portion 313 of the connecting conductor 31D is restricted by the holding body 32D as in the connection member 30C in the modification 3. As a result, the same effect as that of the connecting member 30A in the modification 3 is obtained. That is, even if the first contact between the connecting conductor 31D (solder portion 311) and the first conductive portion 13 of the first substrate 11 is temporarily fixed by soldering, the leg portion 313 of the connecting conductor 31D does not spread outward. Therefore, the force in the direction of peeling from the first substrate 11 does not act on the solder portion 311 soldered to the first conductive portion 13 of the first substrate 11. Therefore, it is possible to prevent cracks from entering the solder connection portion between the connecting conductor 31D (solder portion 311) and the first conductive portion 13 of the first substrate 11. Further, even if the solder portion 311 is cracked by pressing, the position of the connecting conductor 31D does not shift in the lateral direction, and the pressing on the first substrate 11 continues to be applied, so that stable electrical connection is continued.

(Variation Example 5 of Embodiment 1)
Next, a modification 5 of the first embodiment will be described with reference to FIGS. 11A to 11C. FIG. 11A is a perspective view of the connecting member 30E according to the fifth modification of the first embodiment. FIG. 11B is a cross-sectional view of the connecting member 30E. FIG. 11C is a perspective view of the connecting conductor 31E in the connecting member 30E.

As shown in FIGS. 11A to 11C, the connecting member 30E in the present modification is the same as the connection members 30C and 30D in the above modifications 3 and 4, and the connection member 30E and the first substrate 11 are temporarily fixed by soldering. Is going.

On the other hand, in the connection members 30C and 30D in the above-mentioned modifications 3 and 4, the solder portion and the first contact are at the same place, but in the connection member 30E in the present modification, the solder portion and the first contact are separate. It is a place.

Therefore, as shown in FIGS. 11B and 11C, the connection member 30E in this modification has a different shape of the connection conductor 31E from the connection members 30C and 30D in the above modifications 3 and 4.

Specifically, in the connecting member 30E in this modification, the connecting conductor 31E is a spring that elastically contacts the solder portion 311 connected to the first substrate 11 by solder and the second conductive portion 23 of the second substrate 21. It has a portion 312, a connecting portion 314 connected to the first conductive portion 13 of the first substrate 11, and a leg portion 313 connecting the spring portion 312 and the solder portion 311 to the spring portion 312 and the connecting portion 314. The connection portion 314 has a contact portion 314a that comes into contact with the first conductive portion 13 provided on the first substrate 11 when the solder portion 311 is soldered to the first substrate 11.

In this modification, the contact portion between the contact portion 314a of the connection portion 314 and the first conductive portion 13 is the first contact. Therefore, in this modification, the solder portion 311 may or may not be electrically connected to the first conductive portion 13.

Further, even in the connecting member 30E in this modification, the movement of the leg portion 313 is restricted by the holding body 32E. As a result, the same effect as that of the connecting members 30C and 30D in the above-mentioned modifications 3 and 4 is obtained. That is, even if the connecting conductor 31E (solder portion 311) and the first substrate 11 are temporarily fixed by soldering, the leg portions 313 of the connecting conductor 31E do not spread outward, so that they are soldered to the first substrate 11. A force in the direction of peeling from the first substrate 11 does not act on the solder portion 311. Therefore, it is possible to prevent cracks from entering the solder connection portion between the connection conductor 31E (solder portion 311) and the first substrate 11. Further, even if the solder portion 311 is cracked by pressing, the position of the connecting conductor 31D does not shift in the lateral direction, and the pressing on the first substrate 11 continues to be applied, so that stable electrical connection is continued.

(Variation Example 6 of Embodiment 1)
Next, a modification 6 of the first embodiment will be described with reference to FIGS. 12A to 12D. FIG. 12A is a perspective view of the connecting member 30F according to the sixth modification of the first embodiment. FIG. 12B is a cross-sectional view of the connecting member 30F. FIG. 12C is a perspective view of the connecting conductor 31F in the connecting member 30F. FIG. 12D is a plan view of the connecting conductor 31F.

As shown in FIGS. 12A to 12D, the connecting member 30F in this modification has a double spring structure like the connecting member 30 shown in FIGS. 5A to 5C. That is, when the connecting member 30F is fixed to the first substrate 11 and the second substrate 21, the first plate portion 31a of the connecting conductor 31F is elastic in contact with the first conductive portion 13 of the first substrate 11. Along with the deformation, the second plate portion 31b of the connecting conductor 31F is elastically deformed in a state of being in contact with the second conductive portion 23 of the second substrate 21.

The difference between the connecting member 30F in this modification and the connecting member 30 shown in FIGS. 5A to 5C is the arrangement relationship between the first plate portion 31a and the second plate portion 31b in the connecting conductor 31F. That is, as shown in FIG. 12D, in the connecting conductor 31F in the present modification, the first plate portion 31a having the first contact portion 31a1 and the second plate portion 31b having the second contact portion 31b1 are viewed in a plan view. It is sometimes formed so that it does not overlap. That is, in this modification, the first plate portion 31a and the second plate portion 31b do not face each other, and the tip portion of the elastically deformed portion of the connecting conductor 31F is displaced in a plan view.

With this configuration, the height of the connecting member 30F can be lowered. This point will be described with reference to FIGS. 13 and 14. FIG. 13 is a cross-sectional view when the connecting conductor 31 of the connecting member 30 shown in FIGS. 5A to 5C is elastically deformed. FIG. 14 is a cross-sectional view when the connecting conductor 31F of the connecting member 30F in this modification is elastically deformed.

When the connecting member 30 shown in FIGS. 5A to 5C is fixed to the first substrate 11 and the second substrate 21, the connecting conductor 31 is pressed by the first substrate 11 and the second substrate 21, so that the connecting conductor 31 is Elastically deforms. Specifically, the connecting conductor 31 changes from the state shown in FIG. 13 (a) to the state shown in FIG. 13 (b). That is, the shape of the connecting conductor 31 changes so that the tip portion of the first plate portion 31a and the tip portion of the second plate portion 31b come close to each other.

At this time, if the tips of the first plate portion 31a and the second plate portion 31b come into contact with each other and the first plate portion 31a and the second plate portion 31b interfere with each other, the connecting conductor 31 cannot be elastically deformed any more. As a result, the contact state between the first plate portion 31a (first contact portion 31a1) and the first conductive portion 13 of the first substrate 11 deteriorates, or the second plate portion 31b (second contact portion 31b1) and the second The contact state of the substrate 21 with the second conductive portion 23 may be deteriorated. Further, when the first plate portion 31a and the second plate portion 31b of the connecting conductor 31 interfere with each other, the first substrate 11 and the second substrate 21 receive stress (pressing) from the connecting conductor 31 as a reaction force due to this interference. , The first substrate 11 and the second substrate 21 may be chipped or cracked.

Therefore, in order to avoid interference between the first plate portion 31a and the second plate portion 31b of the connecting conductor 31, the strokes of the first plate portion 31a and the second plate portion 31b at the time of elastic deformation of the connecting conductor 31 are increased. However, in this case, it is necessary to increase the height of the holding body 32. Specifically, the height of the holding body 32 needs to be equal to or larger than the total length of the stroke of the first plate portion 31a and the stroke of the second plate portion 31b.

However, when the height of the holding body 32 becomes high, the holding body 32 has a light-shielding property, so that a part of the light of the light source module 10 may be blocked by the holding body 32 to cause a shadow of the light. Then, if an attempt is made to avoid the generation of light shadows by the holding body 32, the height of the entire luminaire may increase.

On the other hand, in the connecting member 30F in the present modification, as shown in FIG. 12D, the first plate portion 31a and the second plate portion 31b in the connecting conductor 31F do not overlap when viewed in a plan view.

As a result, when the connecting member 30F is fixed to the first substrate 11 and the second substrate 21, the connecting conductor 31F is changed from the state shown in FIG. 14 (a) to FIG. 14 (a) like the above-mentioned connecting conductor 31. Although it elastically deforms to the state shown in b), as shown in FIG. 14 (b), the connecting conductor 31 is at a position where the first plate portion 31a and the second plate portion 31b intersect each other in the side view. It can be transformed into. That is, when the connecting conductor 31F is elastically deformed, the stroke of the first plate portion 31a and the stroke of the second plate portion 31b do not interfere with each other.

As a result, the first substrate 11 and the second substrate 21 receive stress from the connecting conductor 31F due to the interference between the first plate portion 31a and the second plate portion 31b, and the first substrate 11 and the second substrate 21 are chipped or cracked. Can be avoided.

Further, since the first plate portion 31a and the second plate portion 31b do not interfere with each other, it is necessary to make the height of the holding body 32 equal to or more than the total length of the strokes of the first plate portion 31a and the second plate portion 31b. There is no. Therefore, since the height of the holding body 32 can be kept low, it is possible to suppress the shadow of light from being generated by the holding body 32. Further, it is not necessary to increase the height of the entire luminaire in order to suppress the generation of the shadow of light by the holder 32, and a thin luminaire can be realized.

(Modification 7 of Embodiment 1)
Next, a modification 7 of the first embodiment will be described with reference to FIGS. 15A to 15C and FIG. FIG. 15A is a perspective view of the connecting member 30G according to the modified example 7 of the first embodiment. FIG. 15B is a cross-sectional view of the connecting member 30G. FIG. 15C is a perspective view of the connecting conductor 31G in the connecting member 30G. FIG. 16 is a partially enlarged cross-sectional view of the connecting member 30G, and shows a cross-sectional view taken along the line XVI-XVI of FIG. 15B.

As shown in FIGS. 15A to 15C, the connecting member 30G in the present modification does not overlap when the first plate portion 31a and the second plate portion 31b are viewed in a plan view, similarly to the connection member 30F in the modification 6. It is formed like this. As a result, when the connecting conductor 31G is elastically deformed, the first plate portion 31a and the second plate portion 31b do not interfere with each other, so that the effect of lowering the height of the holding body 32 can be obtained.

In the connecting member 30G in the present modification, the connecting conductor 31G further extends in the same direction as the extending direction of the first plate portion 31a, the first rotation preventing plate 31f and the extending direction of the second plate portion 31b. It has a second rotation prevention plate 31 g extending in the same direction as the above.

As shown in FIGS. 15C and 16, the first rotation prevention plate 31f is provided at a distance from the first plate portion 31a and is in surface contact with the inner surface of the holding body 32. Further, the second rotation prevention plate 31g is provided at a distance from the second plate portion 31b, and is in surface contact with the inner surface of the holding body 32. In this modification, the first rotation prevention plate 31f and the second rotation prevention plate 31g are both long plates and are connected to the third plate portion 31c.

By providing the first rotation prevention plate 31f and the second rotation prevention plate 31g in this way, it is possible to suppress the connection conductor 31G from rotating around the X axis. This point will be described below.

Unlike the connection conductor 31F in the above modification 6, the first plate portion 31a and the second plate portion 31b are not overlapped in a plan view without the first rotation prevention plate 31f and the second rotation prevention plate 31g being provided. When formed, when the first plate portion 31a and the second plate portion 31b are elastically deformed, a force that causes the connecting conductor 31G to rotate about the X axis acts. As a result, the contact state between the first plate portion 31a and the first conductive portion 13 of the first substrate 11 is poor, or the contact state between the second plate portion 31b and the second conductive portion 23 of the second substrate 21 is poor. Or become.

On the other hand, in the connecting conductor 31G in the present modification, since the first rotation prevention plate 31f and the second rotation prevention plate 31g, each of which is in surface contact with the inner surface of the holding body 32, are provided, they are heavy in a plan view. As shown in FIG. 16, even if the first plate portion 31a and the second plate portion 31b formed so as not to be formed are elastically deformed and a rotational force around the X axis acts on the connecting conductor 31G, the first rotation prevention is performed. Since the plate 31f and the second rotation prevention plate 31g are in surface contact with the inner surface of the holding body 32, it is possible to suppress the connection conductor 31G from rotating around the X axis. That is, the first rotation prevention plate 31f and the second rotation prevention plate 31g function as rotation suppressing portions for suppressing the rotation of the connecting conductor 31G.

In this modification, both the first rotation prevention plate 31f and the second rotation prevention plate 31g were formed on the connecting conductor 31G, but the first rotation prevention plate 31f and the second rotation prevention plate 31g were formed. Only one of them may be formed.

(Variation Example 8 of Embodiment 1)
Next, the modified example 8 of the first embodiment will be described with reference to FIGS. 17A to 17C. FIG. 17A is a perspective view of the connecting member 30H according to the modified example 8 of the first embodiment. FIG. 17B is a cross-sectional view of the connecting member 30H. FIG. 17C is a perspective view of the connecting conductor 31H in the connecting member 30H.

As shown in FIGS. 17A to 17C, the connecting conductor 31H of the connecting member 30H in the present modification is the first plate portion 31a and the second plate, similarly to the connecting conductor 31G of the connecting member 30G in the above modification 7. The first rotation prevention plate 31f and the second rotation prevention plate 31g for suppressing the rotation of the connecting conductor 31H around the X axis are formed so as not to overlap with the portion 31b when viewed in a plan view. ing.

In this modification, the first rotation prevention plates 31f are formed in pairs so as to sandwich the first plate portion 31a, and the front end portion and the rear end portion of the first rotation prevention plate 31f are connected to each other. There is. Similarly, the second rotation prevention plate 31g is formed in pairs so as to sandwich the second plate portion 31b, and the front end portion and the rear end portion of the second rotation prevention plate 31g are connected to each other.

As a result, the rigidity of the first rotation prevention plate 31f and the second rotation prevention plate 31g is higher than that of the modified example 7, so that when the first plate portion 31a and the second plate portion 31b are elastically deformed, the connecting conductor 31G is formed. Even if a large rotational force is applied, it is possible to suppress the connection conductor 31G from rotating around the X axis without deforming the connection conductor 31G (the first rotation prevention plate 31f and the second rotation prevention plate 31g).

(Embodiment 2)
Next, the lighting fixture 2 according to the second embodiment will be described. FIG. 18 is a cross-sectional view of the lighting fixture 2 according to the second embodiment.

As shown in FIG. 18, the overall configuration of the luminaire 2 in the present embodiment is the same as that of the luminaire 1 according to the first embodiment shown in FIG. Therefore, in the present embodiment, the differences from the first embodiment will be mainly described with reference to FIGS. 19 to 21. 19 is a diagram showing a connection relationship between the light source module 10, the power supply module 20A, and the connecting member 30 in the lighting fixture 2 according to the second embodiment, where FIG. 19A is a plan view and FIG. 19B is a plan view. The cross-sectional view of VIB-VIB and (c) are the cross-sectional views of VIC-VIC of (a). 20 and 21 are exploded views of the light source module 10, the power supply module 20A, and the connecting member 30 in the luminaire 2, where FIG. 20 (a) is an enlarged side view and FIG. 20 (b) is an enlarged front view. FIG. 21 is an enlarged plan view.

In the first embodiment, the circuit element 22 of the power supply module 20 is provided on the surface (first main surface 21a) of the second substrate 21 on the first substrate 11 side, whereas in the present embodiment. As shown in FIGS. 18 to 21, the circuit element 22 of the power supply module 20A is provided on the surface of the second substrate 21 opposite to the surface on the first substrate 11 side (second main surface 21b). ..

Further, for the purpose of enhancing the color rendering property, a red fluorescent substance or a green fluorescent substance may be further mixed in addition to the yellow fluorescent substance. Further, an LED chip that emits a color other than blue may be used. For example, an ultraviolet LED chip that emits ultraviolet light having a shorter wavelength than the blue light emitted by the blue LED chip is used and is excited mainly by ultraviolet light. It may be configured to emit white light by a blue phosphor, a green phosphor and a red phosphor that emit blue light, red light and green light.

Further, in the above embodiment, the light source module 10 may be configured to be dimmable and / or tonal controllable.

This makes it possible to realize an LED module capable of color matching control.

Further, in the above embodiment, the LED is exemplified as the light source of the LED element 12, but other solid light emitting elements such as a semiconductor light emitting element such as a semiconductor laser, an organic EL (Electroluminescence) or an inorganic EL may be used.

A functional unit such as a remote light receiving device for remote operation may be built in.

Further, in the above embodiment, the lighting fixture has been described as an example, but the present invention can be applied to other than the lighting fixture. That is, the first substrate and the second substrate are not limited to the light source substrate and the power supply substrate. Specifically, an electronic device or the like including a first substrate having a first conductive portion, a second substrate having a second conductive portion, and a connecting member for electrically connecting the first conductive portion and the second conductive portion. Can also be applied to.

The first board and the second board are not limited to the light source board and the power supply board, and a board on which circuit parts are mounted may be used, or only a wiring pattern in which circuit parts are not mounted may be used. The formed substrate may be used, or a substrate having a functional element other than a light emitting element such as a display element, a sensor element, and a communication module may be used. The first substrate and the second substrate are not particularly limited as long as they are substrates having a conductive portion.
