Description

  Embodiments described herein relate generally to a light source module, a lamp, and an illumination device.

  In recent years, lighting devices using light emitting elements such as light emitting diodes (hereinafter referred to as LEDs) as light sources have been widely put into practical use. A lighting device using such a light emitting element has a heat dissipation structure that efficiently dissipates heat generated in the light emitting element. For example, a configuration is widely adopted in which heat from a substrate on which an LED is mounted is radiated by a heat dissipation structure made of aluminum having good thermal conductivity.

  In addition, a contact that is a terminal for supplying power to a light emitting element that is a light source is provided in a hole formed in a substrate on which the light emitting element is mounted, and a lamp including a light source module having the light emitting element is attached to a socket. Then, the lamp-side contact comes into contact with the socket-side electrical contact portion.

  In the case of adopting the heat dissipation structure as described above, an insulating member for ensuring electrical insulation is required. From the viewpoint of simplification of the structure, in order to eliminate this insulating member, the thermal conductivity is not as high as that of aluminum, but it is conceivable to use a ceramic substrate having electrical insulation.

However, when a ceramic substrate is used, it is not preferable in terms of cost and the like to form a hole for a contact as a terminal in the ceramic substrate itself.
Furthermore, the connection between the power supply contact and the wiring pattern connected to the light emitting element must be performed by soldering on the ceramic substrate. However, the difference between the thermal expansion coefficient of the ceramic substrate and the thermal expansion coefficient of the solder is required. Therefore, when the lighting device is turned on and off, the temperature of the light emitting element and the vicinity thereof rises and falls, and there is a risk that cracks due to stress caused by a difference in thermal expansion may occur in the solder of the terminal on the ceramic substrate.

  In the light source module of the embodiment, a light emitting unit is mounted, a plurality of wiring patterns connected to the light emitting unit are provided, an insulating ceramic substrate, one end is connected to a power feeding unit, and power is supplied to the light emitting unit A plurality of contacts, a support member for supporting the plurality of contacts, and the other end of each of the plurality of contacts are fixed to the ceramic substrate and electrically connected to one of the plurality of wiring patterns. An electrical connection portion to be connected; and a fixing portion for fixing the support member to the ceramic substrate.

  The light emitting unit of the embodiment uses an LED as the light emitting element, but the light emitting element may be another light emitting element such as a laser diode other than the LED.

  The ceramic substrate of the embodiment is an aluminum oxide (alumina) substrate, but the ceramic substrate may be a substrate such as aluminum nitride other than aluminum oxide.

  The contact of the embodiment is a plate-like or leaf-spring-like member, but the contact may be a member having a shape other than a plate-like or leaf-spring shape.

  The electrical connection portion of the embodiment is solder, but the electrical connection portion may be formed using a conductive material other than solder.

  The fixing portion of the embodiment is solder, but the fixing portion may be formed using a material other than solder. The fixing portion is configured separately from the electrical connection portion, that is, it is not a configuration in which the support member and the ceramic substrate are directly fixed by the fixing portion. As a result, the fixed part and the electrical connection are respectively fixed to the ceramic substrate. However, due to thermal expansion or contraction of the ceramic substrate, the fixed part and the electrical connection part individually follow the movement of the ceramic substrate, that is, fixed. The portion and the electrical connection portion can move with each other and do not interfere directly with each other. For this reason, compared with the case where a fixing | fixed part and an electrical-connection part are formed integrally, the fixation to a ceramic substrate is performed reliably and the influence of a thermal stress can be reduced.

  The socket 2 has a socket body 11 made of a resin molded product having a flat, substantially cylindrical shape, for example. A concave groove 11A having a partial arc shape in plan view is extended in the vertical direction at appropriate positions on the outer peripheral portion of the socket body 11 (for example, at six convenient positions for each predetermined pitch). A screw insertion hole 11B is formed in the wall portion at the upper end of these concave grooves 11A. The socket 2 is fixed to a ceiling portion or the like via a screw 12 inserted from the lower side into the screw insertion hole 11B.

  As shown in FIG. 2, an inward flange having a substantially annular shape is integrally formed at the lower end portion of the socket body 11.

  Further, the connector receiving portion 16 has a plurality of contact piece portions 18 that come into contact with each other as contacts 32 as terminals of the connector 22c on the lamp 3 side. Each contact piece 18 is a female terminal having two plate-like portions having springiness, and contacts the contact 32 so that the contact 32 that is a male terminal is sandwiched between the two plate-like portions. A corresponding harness 19 is connected to each contact piece 18. Since the contact 32, which is a plate-like member, comes into contact with the two plate-like portions, the contact area between the contact piece 18 and the contact 32 is large.

  FIG. 5 is an exploded view as seen from the lower oblique direction of the lamp according to the present embodiment. FIG. 6 is an exploded view of the lamp according to the present embodiment as seen from the upper oblique direction. The configuration of the lamp 3 will be described with reference to FIGS.

It is a member. An annular tapered surface portion 21 </ b> C that is inclined inward from the outer frame portion 21 </ b> A is formed on the distal end side of the housing 21.

  A lens portion 21D for irradiating light from the module substrate 22 within a predetermined angle range is integrally formed inside the annular tapered surface portion 21C.

  The leaf spring member 23 is made of a metal such as stainless steel and has a substantially square shape having a shape similar to the shape of the inner frame portion 21B in plan view, and has an opening portion 23A along the shape of the lens portion 21D on the inner side. It is the plate-shaped member which has. The leaf spring member 23 has leaf spring portions 23B that are bent so as to protrude toward the proximal end at three locations on the outer edge, and is disposed in the inner frame portion 21B.

  The module substrate 22 has a substantially square shape having a shape similar to the shape of the inner frame portion 21B in plan view, and an aluminum oxide (alumina) on which a light emitting portion 22B having a circular shape in plan view is mounted at the center portion. This is a ceramic substrate. The light emitting unit 22B includes LEDs 22A that are a plurality of light emitting elements of surface mount type (SMD type) or chip on board type (COB type). Two connectors 22C are fixed to one side of the module substrate 22. The module substrate 22 is disposed so as to sandwich the leaf spring member 23 in the inner frame portion 21B.

The heat radiating plate 24 is a plate-like plate made of aluminum having a substantially circular shape in plan view similar to the shape of the outer frame portion 21A and having a notch 24A formed in part.
Further, the heat radiating plate 24 is provided with four screw holes 24B. The heat radiating plate 24 is screwed with screws 24C so as to sandwich the leaf spring member 23 and the module substrate 22 with the housing 21. And screwed to the housing 21. When the heat radiating plate 24 is screwed to the housing 21, the upper surface of the module substrate 22 sandwiched between the heat radiating plate 24 and the housing 21 is radiated by the three plate spring portions 23 </ b> B of the plate spring member 23. The module substrate 22 is fixed in the housing 21 by being pressed and brought into close contact with the plate 24. Therefore, the heat generated in the module substrate 22 is transmitted to the heat radiating plate 24.

  A heat radiating sheet 25 is attached to the heat radiating plate 24. The heat dissipating sheet 25 is an aluminum plate-like plate having a substantially circular shape in plan view similar to the shape of the outer frame portion 21A and having a notch 25A formed in part. Therefore, the heat generated in the module substrate 22 is transmitted to the heat radiating sheet 25 through the heat radiating plate 24 and is radiated from the heat radiating sheet 25.

Note that a notch 24A is formed in the heat dissipation plate 24, and the notch 24A is formed so as not to overlap the connector 22c when seen in a plan view. Therefore, an insulation distance between the connector 22C and the heat radiating plate 24 is ensured, and heat from the light emitting portion 22B is hardly transmitted to the connector 22C.
The lamp 3 configured as described above can be attached to and removed from the socket 2.

FIG. 7 is a plan view of the module substrate 22 which is a light emitting module. FIG. 8 is a cross-sectional view for explaining the structure of the lamp 3 in the vicinity of the connector 22C.
As shown in FIG. 7, on the module substrate 22, a plurality of wiring patterns 31 connected to the respective LEDs 22A in the light emitting section 22A are provided. Two connectors 22 c are mounted on the module substrate 22. Each connector 22 is provided with a plurality (three in this case) of contacts 32. From each connector 22C, both ends of each contact 32 as a terminal protrude. One end of the contact 32 is connected to the power feeding unit, and is a terminal for supplying power to the light emitting unit 22B.

  Each end portion 32A of the plurality of contacts 32 protruding to the light emitting portion 22B side of the connector 22C and one end of each wiring pattern 31 are soldered by solder 33. Therefore, the module substrate 22 that is an insulating ceramic substrate is provided with the light emitting portion 22B and a plurality of wiring patterns 31 connected to the light emitting portion 22B.

  As shown in FIG. 8, the end portion 32A of each contact 32 protruding to the light emitting portion 22B side of the connector 22C is fixed to the module substrate 11 by solder 33 and is electrically connected to each wiring pattern. This solder 33 constitutes an electrical connection portion between each contact 32 and each wiring pattern.

  Further, the contact 32 as a terminal is a plate-like conductive metal member and has a substantially crank shape as shown in FIG. As described above, the end portion 32A on the light emitting portion 22B side of each contact 32 is connected to the wiring pattern 31 of the module substrate 22 by the solder 33. Then, the end portion 32 </ b> B of each contact 32 protruding toward the outer peripheral side of the lamp 3 protrudes toward the outer peripheral side of the lamp 3.

  The end portion 32B of the contact 32 may have a leaf spring shape as shown in FIG. FIG. 9 is a cross-sectional view for explaining the structure in the vicinity of the connector 22C having a leaf spring-shaped contact.

  The leaf spring-shaped contact 32W has an end portion 32WB that is bent so as to have elasticity. The end portion 32WB extends upward from the opening portion 34Wa of the support member 34W, and is bent in the shape of a dog on the way, and has elasticity. An end portion 32WA of the contact 32W on the light emitting portion 22B side is connected to the wiring pattern 31 of the module substrate 22 by a solder 33.

Further, the end portion 32WB on the outer peripheral side of the lamp 3 is supported by the support member 34W so as not to move in the vertical direction at the opening 34Wa of the support member 34W but to be movable in the horizontal direction.
Therefore, the contact of the connector 22C may have a shape as shown in FIG.

  In the present embodiment, as shown in FIG. 8, the end portion 32B of the contact 32 is a plate-like member and has a so-called knife edge shape, so that the contact area between the end portion 32B and the contact piece portion 18 is increased. As a result, not only can the amount of heat radiation be increased, but also the electrical connection between the end 32B and the contact piece 18 can be ensured.

  Further, when the contact 32 is a knife-edge shaped plate-like member, the contact area and the contact pressure can be sufficiently secured, so that the gold plating for improving the electrical connection between the end portion 32B and the contact piece portion 18 is achieved. Since processing is unnecessary, there is an advantage that it is advantageous in terms of cost. In addition, since the end portion 32B of the contact 32 is a plate-like member, there is an advantage that the size of the lighting device 1 in the vertical direction can be reduced.

  Furthermore, when the end portion 32B of the contact 32 is a plate member having a knife edge shape, there is an advantage that when the lamp 3 is mounted on the socket 2, the contact 32 is not stressed.

  As shown in FIG. 8, each connector 22 </ b> C includes a plurality (here, three) contacts 32 and a support member 34 that supports the plurality of contacts 32. The support member 34 is provided with holes 34A in which the respective contacts 32 are disposed. The support member 34 is a resin member made of an insulating material, and is configured by integral molding or a plurality of members.

  FIG. 10 is a perspective view of the support member 34. As shown in FIG. 10, a plurality (two in this case) of protrusions 34 </ b> B are provided on one surface of the support member 34. The protruding portion 34B has a tip portion 34Ba having a widened tip portion. A connecting member 35, which is a metal member such as stainless steel, is fitted and fixed to the protrusion 34B.

  As shown in FIG. 8, the support member 34 of the connector 22C is fixed to the module substrate 22 by the solder 36 via the metal member 35 fitted to the tip end portion 34Ba. The solder 36 constitutes a fixing portion that fixes the support member 34 to the module substrate 22.

  A plurality (three in this case) of holes 34A of the support member 34 of each connector 22C has a shape for fixing the end 32B so that the end 32B of the contact 32 does not move in the vertical direction of the support member 34. Yes. That is, the opening 34Aa of the hole 34A on the outer peripheral side of the lamp 3 has such a shape that the end 32B can move so as to slide in the lateral direction but does not move in the vertical direction. That is, the plurality of contacts 32 are supported by the support member 34 so as to be movable relative to the support member 34.

FIG. 11 is a view for explaining the connection between the contact 32 of the connector 22 </ b> C and the contact piece 18 in the connector receiving portion 16.
When the lamp 3 is mounted in the socket 2, the end portions 32B of the contacts 32 protruding from the support member 34 of the connector 22C of the lamp 3 enter the slit 17 provided in the connector receiving portion 16 of the socket 2, and the end portions 32B are The contact piece 18 is pressed and brought into contact so as to be sandwiched between the two plate-like portions. That is, the contact piece portion 18 is a female terminal, and the end portion 32B of the male terminal enters between the two plate-like portions of the contact piece portion 18.

  The module substrate 22 which is a ceramic substrate, the contacts 32 electrically connected to the module substrate 22 by solder 33, and the support member 34 fixed to the module substrate 22 by solder 36 constitute a light source module.

(Function)
The operation of the socket 2 and the lamp 3 in the lighting device 1 configured as described above will be described. When the lamp 3 is mounted on the socket 2 fixed to the ceiling and the lighting device 1 is turned on, the light emitting unit 22B of the module substrate 22 emits light. The heat generated in the light emitting unit 22B is transmitted to the solder 33 through the module substrate 22 which is a ceramic substrate. When the lighting device 1 is turned off, the heat generated in the light emitting unit 22B is radiated to the outside from the module substrate 22 through the heat radiating plate 24 and the heat radiating sheet 25.

  Further, the support member 34 of the connector 22C supports the plurality of contacts 32, and is further fixed to the module substrate 22 with solder 36 via a connection member 35 fitted to the protrusion 34B.

  The position of the solder 36 that fixes the support member 34 to the module substrate 22 is farther from the light emitting portion 22B that is the light source than the position of the solder 33 that fixes the end 32A of the contact 32 to the module substrate 22. That is, the solder 36 that is a fixing portion is provided at a position farther from the light emitting portion 22B than the solder 33 that is an electrical connection portion.

  In the module substrate 22 that is a ceramic substrate, the heat dissipation amount in the direction orthogonal to the surface of the module substrate 22 is larger than the heat dissipation amount in the surface direction of the module substrate 22.

  Therefore, by reducing the volume of the solder 33 closer to the light emitting portion 22B than the solder 36 and increasing the volume of the solder 36 than the solder 33, the thermal expansion and contraction of the solder 33 are repeated by turning on and off the lighting device 1. When this occurs, cracks are unlikely to occur in the solder 33, and the support member 34 of the connector 22C can be firmly fixed to the module substrate 22.

  Further, the end portion 32B of the contact 32 pushes the end portion 32B of the contact 32 into the contact piece 18 when the lamp 3 is attached to the socket 2, so that stress is applied to the end portion 32B in the direction of the arrow A1 in FIG. It takes. Further, when the lamp 3 is removed from the socket 2, the end portion 32B of the contact 32 is pulled out from the contact piece portion 18, so that stress is applied to the end portion 32B of the contact 32 in the direction of arrow A2 in FIG.

  However, since the opening 34Aa of the hole 34A on the outer peripheral side of the lamp 3 has such a shape that the end 32B does not move in the vertical direction (that is, in the directions of arrows A1 and A2), the end 32A of the contact 32 has No stress is applied.

  The opening 34Aa of the hole 34A on the outer peripheral side of the lamp 3 has a shape in which the end 32B is movable in the lateral direction (that is, the direction of the arrow A3 orthogonal to the directions of the arrows A1 and A2). 33 and the solder 36 are individually moved by thermal expansion or contraction of the module substrate 22, and the influence of the solder 33 and the solder 36 on each other with respect to the lateral thermal stress received from the module substrate 22 is reduced. The occurrence of cracks in the solder 33 and the solder 36 is reduced.

  As described above, according to the above-described embodiment, in the light source module employing the ceramic substrate, the light source module, the lamp, and the illumination device that prevent the occurrence of cracks in the solder portion between the ceramic substrate and the power supply contact are realized. can do.

  Next, a modified example will be described.

(Modification)
Each contact 32 described above is a single plate-like member, but each contact 32 may be divided into a plurality of contacts, and the divided contacts may be connected by a conductive member.

  FIG. 12 is a cross-sectional view for explaining the structure in the vicinity of the connector 22C of the lamp 3 having contacts divided into a plurality of parts. 12, the same components as those in FIG. 8 are denoted by the same reference numerals.

  As shown in FIG. 12, the contact 32X is divided into a plurality (here, two). The two divided contacts 32Xa and 32Xb are electrically connected by a conductive member 41. Both ends of the conductive member 41 are connected to the two contacts 32Xa and 32Xb by solder 42, respectively.

  The contact 32X, the support member 34, and the like expand due to the heat generated in the light emitting unit 22B, and the contact 32X, the support member 34, and the like contract when no heat is generated. However, according to the configuration of FIG. 12, even if this expansion and contraction due to heat occurs, the stress from other contacts is not directly applied to or received by the contact 32Xa of the contact 32X on the end portion 32A side. There are also few.

  FIG. 13 is a cross-sectional view for explaining another example of the structure in the vicinity of the connector 22C of the lamp 3 having contacts divided into a plurality of portions. 13, the same components as those in FIG. 8 are denoted by the same reference numerals.

  As shown in FIG. 13, the contact 32Y is divided into a plurality (here, two) and has two divided contacts 32Ya and 32Yb. The base end side of one of the two contacts 32Ya and 32Yb has an extending portion 32Yc. Further, the end portion of the rectangular conductive member 51 is joined to the base end side of the contact 32Yb by solder (not shown) along the extending portion 32Yc. The tip end portion of the contact 32Ya is sandwiched between the extending portion 32Yc and the conductive member 51 so as to be slidable.

  The contact 32Y and the support member 34 are expanded by the heat generated in the light emitting portion 22B, and when the heat is not generated, the contact 32Y and the support member 34 are contracted. However, according to the configuration of FIG. 13, the contact Ya and the contact Yb are connected so that the tip end portion of the contact 32Ya is slidably sandwiched between the extension portion 32Yc and the extension portion 51. Even if the expansion and contraction due to heat occur, the contact 32Ya of the contact 32Y on the end portion 32A side is not directly subjected to or receives a stress from other members.

As described above, in this modification, each of the plurality of contacts is divided into at least two members, and the divided members are electrically connected to each other by a conductive wire or contact.
Therefore, according to the configuration of this modification, even if the contacts 32X and 32Y, the support member 34, and the like expand and contract due to heat, it is possible to prevent generation of stress on the end portions 32A of the contacts 32X and 32Y.

  Although several embodiments of the present invention have been described, these embodiments are illustrated by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
