The substrate 25 has a first surface 25a and a second surface 25b opposite to the first surface 25a.

  The heat transfer member 21 supports the substrate 25 on which the light source 26 is provided. In addition, the heat transfer member 21 fixes the substrate 25 by sandwiching it between the cover 22 (mounting portion 22a). In this case, the first surface 21a of the heat transfer member 21 and the second surface 25b of the substrate 25 are in contact with each other.

  The cover 22 covers the light source 26 so that light from the light source 26 provided on the substrate 25 is emitted into the internal space. The cover 22 protects the light source 26 from external force and dust. The cover 22 is light transmissive. The cover 22 is light transmissive with respect to the light emitted from the light source 26. The cover 22 is, for example, milky white and has light diffusibility. The cover 22 may be transparent.

However, the holding member 23 is preferably made of the metal material as described above. Thereby, for example, the durability of the holding member 23 can be improved. Further, the holding member 23 is made of, for example, a single plate material. Thereby, for example, the number of parts can be reduced. For example, the cost of the light source module 20 can be suppressed. For example, when a resin material is used for the holding member 23, the holding member 23 is preferably a single part formed by injection molding or the like.

  The side plates 24 are provided at both ends of the cover 22 in the longitudinal direction. The shape of the side plate 24 is a substantially fan shape.

Each light source 26 is arranged side by side on the first surface 25 a of the substrate 25. The number of the light sources 26 may be arbitrary. For example, the number of the light sources 26 may be one.

For example, a light emitting diode (LED) is used as the light source 26. The light source 26 may be an organic light emitting diode (OLED), an inorganic electroluminescent light emitting element, an organic electroluminescent light emitting element, or another electroluminescent light emitting element. The light source 26 may be a light bulb or the like.
Hereinafter, the material of the heat transfer member 21 and the positional relationship between the heat transfer member 21 and other components will be described.

  As illustrated in FIG. 5, the cover 22 includes a flat base portion 22A and a curved curved portion 22B. The cover 22 is provided with a surrounding portion 22C, and the surrounding portion 22C has a base portion 22A and a curved portion 22B. A space S is formed between the base portion 22A and the curved portion 22B, that is, inside the surrounding portion 22C. A mounting portion 22a is formed on the center side of the base portion 22A so as to bend toward the space S inside the cover 22. On the base portion 22A, a bent portion 22b extends in the opposite direction with respect to the space S between the placement portion 22a and the curved portion 22B.

  The substrate 25 is provided between the heat transfer member 21 and the placement portion 22 a of the cover 22. The heat transfer member 21 is provided in a rectangular shape along the second surface 25b of the substrate 25 so as to be in contact with the second surface 25b of the substrate 25, for example.

  The heat transfer member 21 is formed using a resin having higher thermal conductivity than the surrounding portion 22C and having electrical insulation. The heat transfer member 21 is formed using, for example, a high thermal conductive resin. For example, the heat transfer member 21 is formed using a polycarbonate (PC) resin, a polybutylene terephthalate (PBT) resin, a polyamide (PA) resin, or the like. The heat transfer member 21 is not limited to the resin described above, and can be formed using a known resin having thermal conductivity. Further, the heat transfer member 21 may be formed using a plurality of resins. A heat conductive filler may be contained in the resin forming the heat transfer member 21. Further, in order to increase the thermal conductivity of the heat transfer member 21, the heat transfer member 21 may contain ceramic, carbon, or the like.

  Further, since the heat transfer member 21 is formed using a heat conductive resin and is provided in contact with the second surface 25b of the substrate 25, the insulation of the substrate 25 can be improved. For example, since the heat transfer member 21 is formed using a heat conductive resin and the cover 22 (mounting portion 22a) is formed using a resin, the insulation around the substrate 25 can be increased. . By making the insulating property of the substrate 25 high, the grounding treatment of the substrate 25 that is necessary when a chassis such as metal is in contact with the second surface 25b of the substrate 25 may be omitted. For example, in the light source module 20, it is not necessary to ground the substrate 25 with a ground wire or the like.

  Since the heat transfer member 21 has thermal conductivity and is provided in contact with the second surface 25 b of the substrate 25, heat from the light source 26 provided on the substrate 25 is transmitted to the heat transfer member 21. It becomes easy to be transmitted to the outside of the light source module 20. Thereby, the heat dissipation of the light source module 20 improves.

  The mounting portion 22a is a part of the cover 22 that comes into contact with a part of the first surface 25a of the substrate 25 and extends toward the inside of the light source module 20 (for example, a portion where the light source 26 is provided). Part. Moreover, the mounting part 22a is provided in a rectangular shape along the longitudinal direction of the substrate 25, for example. The placement portion 22a may be partially formed at several locations in the longitudinal direction of the substrate 25.

  The mounting portion 22 a is formed by providing a step in the cover 22 toward the inside of the light source module 20. Specifically, the placement portion 22 a is formed in a step shape so as to bend toward the space S inside the cover 22. The mounting portion 22a accommodates the substrate 25 in the step portion. For example, the mounting portion 22 a is accommodated so as to face the side surface of the substrate 25. In this case, the side surface of the substrate 25 is a surface provided between the first surface 25 a and the second surface 25 b of the substrate 25. When a part of the first surface 25a of the substrate 25 is placed on the placement portion 22a by the placement portion 22a, the substrate 25 is laterally moved (for example, in a direction from the heat transfer member 21 toward the cover 22). It is possible to suppress movement in the vertical direction). Accordingly, the substrate 25 is stably fixed between the heat transfer member 21 and the cover 22.

  As indicated by an arrow a1 in FIG. 6, the substrate 25 is attached to the first surface 21a of the heat transfer member 21 using a known fixing means such as a screw.

  The board | substrate 25 may be attached to the 1st surface 21a of the heat-transfer member 21 through a junction part, for example. Such a joining part is a joining agent containing a metal material, for example. The joining portion is a metal joining agent having thermal conductivity, for example, an alloy solder of lead (Pb) and tin (Sn). A lead-free solder containing silver (Ag) or copper (Cu) may be used as the joint.

  As shown by the arrow a2 in FIG. 6, after the substrate 25 is attached to the heat transfer member 21, the substrate 25 is sandwiched and fixed by the heat transfer member 21 and the mounting portion 22a. After the substrate 25 is sandwiched between the heat transfer member 21 and the mounting portion 22a, the heat transfer member 21 is fixed to the cover 22 using, for example, screws. As a result, the substrate 25 is fixed to the light source module 20.

  In this embodiment, the mounting part 22a is formed by providing a step on the cover 22 toward the inside of the light source module 20, and the substrate 25 is sandwiched between the heat transfer member 21 and the mounting part 22a. On the other hand, as shown in FIG. 7, the substrate 25 and the heat transfer member 21 are slid and fixed between the first portion 22 c and the second portion 22 d of the cover 22 to fix the substrate to the light source module 20. May be.

  In such a case, the first portion 22c is integrally formed with the base portion 22A of the surrounding portion 22C. The second portion 22d is formed integrally with the base portion 22A of the surrounding portion 22C so as to form a gap with the first portion 22c. The substrate 25 and the heat transfer member 21 are inserted into the gap formed by the first portion 22c and the second portion 22d so as to slide, and the substrate 25 and the heat transfer member 21 are fixed. As a result, the substrate is fixed to the light source module 20.

  The first portion 22c and the second portion 22d are portions that are part of the cover 22 and extend toward the inside of the light source module 20 (for example, a portion where the light source 26 is provided). The first portion 22c and the second portion 22d are provided in a rectangular shape along the longitudinal direction of the substrate 25, for example. The first portion 22 c and the second portion 22 d are formed by providing a step in the cover 22 toward the inside of the light source module 20. The first portion 22 c and the second portion 22 d may be partially formed at several locations in the longitudinal direction of the substrate 25. The first portion 22 c and the second portion 22 d may be formed using the same material as the heat transfer member 21.

  As shown in FIG. 8, the substrate 25 may be fixed by attaching a holding member 23 to the cover 22 from the second surface 21 b side of the heat transfer member 21. As described above, the holding member 23 is a member that fixes the elastic body 30 and holds the elastic body 30 to the cover 22. In such a case, for example, without attaching the substrate 25 to the first surface 21a of the heat transfer member 21, the substrate 25 can be sandwiched and fixed by the heat transfer member 21 and the mounting portion 22a.

  The holding member 23 includes a grip portion 23a and a fixing portion 23b. The grip part 23a is provided at both ends of the fixed part 23b. The grip portion 23 a grips the bent portion 22 b of the cover 22. The holding member 23 is fixed to the cover 22 using screws or the like. Thereby, the holding member 23 is attached to the cover 22.

  The gripping part 23a is, for example, a leaf spring, and suppresses the engagement of the cover 22 from being released by sandwiching the cover 22. The holding member 23 suppresses the opening of the cover 22 by being sandwiched between the gripping portions 23a. In addition, an elastic body 30 is provided in the fixing portion 23b.

  As shown in FIG. 9, when the substrate 25 is fixed by attaching the holding member 23 to the cover 22 from the second surface 21 b side of the heat transfer member 21, the convex portion 21 c is provided on the first surface 21 a of the heat transfer member 21. be able to. For example, when the substrate 25 is sandwiched and fixed by the heat transfer member 21 and the mounting portion 22a without attaching the substrate 25 to the first surface 21a of the heat transfer member 21, the heat transfer member 21 is provided with a convex portion 21c. 25 positions are determined. The convex portion 21c is, for example, a positioning rib. The convex part 21c can be formed using the same material as the heat-transfer member 21, for example.

  The convex portion 21 c can be provided along the longitudinal direction of the substrate 25, for example. The two convex portions 21 c are provided at both ends of the substrate 25 along the longitudinal direction of the substrate 25. For example, the substrate 25 is provided between the two convex portions 21c. Thereby, the position shift between the heat transfer member 21 and the substrate 25 is suppressed, and the substrate 25 can be stably fixed to the cover 22.

  In the lighting fixture 100 of the present embodiment, the heat transfer member 21 having a thermally conductive resin is provided in contact with the second surface 25 b of the substrate 25. Providing such a heat transfer member 21 can increase the insulation around the substrate 25. By making the insulating property of the substrate 25 high, the grounding treatment of the substrate 25 that is necessary when a chassis such as metal is in contact with the second surface 25b of the substrate 25 may be omitted. Thereby, the assembly property of the lighting fixture 100 can be improved.

  The heat transfer member 21 is formed using a heat conductive resin, and is provided in contact with the second surface 25 b of the substrate 25. Thereby, the heat dissipation of the cover 22 can be improved without providing a chassis of metal or the like.

  In the present embodiment, the heat transfer member 21 is fixed with the substrate 25 sandwiched between the mounting portion 22a. For example, the heat transfer member 21 may be formed integrally with the placement portion 22a. That is, the heat transfer member 21 may be a part of the cover 22. For example, the heat transfer member 21 is integrally formed by different material molding such as two-color molding. In such a case, for example, the cover 22 includes a heat conducting portion having thermal conductivity and a light transmitting portion (for example, the mounting portion 22a) having light transmittance connected to the heat conducting portion. Moreover, the board | substrate 25 can be inserted and accommodated between such a heat conductive part and the mounting part 22a.
