As a result, the V-shaped locking springs 80 are restored to the first state (restored state) in the long holes of the spring receivers 24 and are engaged with the long holes, so that the LED light source unit 50 is illuminated. It can be attached to the instrument body 10 with almost no gap. In addition, since the removal method of the LED light source unit 50 can be performed by the reverse procedure of the said attachment procedure, description is abbreviate | omitted.

  As described above, the luminaire 1 and the LED light source unit 50 according to the present embodiment include the long LED substrate 60 in which the plurality of LEDs 62 are arranged along the longitudinal direction, and the lower surface portion 71 on which the LED substrate 60 can be mounted. And a long unit main body 70 configured to be attached to the lighting fixture main body 10 with the upper surface portion facing the lighting fixture main body 10, and a power supply device 90 that supplies power to the plurality of LEDs 62. The unit main body 70 has an elongated hollow space 74 extending along the longitudinal direction on one long side, and at least a portion of the unit main body 70 forming the hollow space 74 is made of metal. The power supply device 90 is formed in a long shape that can be accommodated in the hollow space 74.

  According to such a lighting fixture 1 and the LED light source unit 50, the power supply device 90 is formed in a long shape, and the hollow space 74 in which the power supply device 90 is accommodated is formed of metal, whereby the power supply device 90 is provided. Since the heat from can be dispersed over a wide range and the heat dissipation can be improved, it is possible to increase the energy efficiency, extend the life of the LED, and make the LED performance uniform. Moreover, according to the lighting fixture 1 and LED light source unit 50 which concern on this embodiment, the hollow space 74 which accommodates the power supply device 90 is formed in one long side part side of the unit main body 70, Therefore Various components (for example, the wiring fixture 56, the V-shaped locking spring 80, the mounting bracket 81a, the fixing screw 81b, the power receiving connector, etc.) attached to the upper surface of the unit body 70 while suppressing the length in the width direction, Since it is possible to avoid interference with various members that may protrude from the luminaire main body 10 side, the entire luminaire 1 can be thinned. Furthermore, according to the luminaire 1 and the LED light source unit 50 according to the present embodiment, the longitudinal arrangement of the power supply device 90 in the hollow space 74 is free, so the power supply length is increased and the height is suppressed. Substrate design becomes possible, whereby the entire lighting fixture 1 can be made thinner.

  Moreover, the lighting fixture 1 and LED light source unit 50 which concern on this embodiment are the metal extrusion materials in which the unit main body 70 was shape | molded by extrusion molding. According to such a lighting fixture 1 and the LED light source unit 50, the unit main body 70 which has structures, such as the hollow space 74 and the insertion groove 73, can be formed, without requiring a complicated process and a several metal board | plate material. Therefore, the number of parts can be reduced. Moreover, since the hollow space 74 is formed so that the unit main body 70 shape | molded by extrusion molding may penetrate from the one end part to the other end part, it has various power supply length (length of a longitudinal direction). The power supply device 90 can be handled.

  Furthermore, as for the lighting fixture 1 and LED light source unit 50 which concern on this embodiment, the unit main body 70 is formed from the material which has aluminum as a main component. According to such a lighting fixture 1 and the LED light source unit 50, as compared with the case where the unit main body 70 is formed of a metal such as stainless steel or iron, for example, it is possible to exhibit even more excellent heat dissipation, The unit body 70 can be reduced in weight.

  Furthermore, the luminaire 1 and the LED light source unit 50 according to the present embodiment protrude from the lower surface portion 71 of the unit main body 70 from the substrate accommodating recess 72a capable of accommodating the LED substrate 60 and the opening edge of the substrate accommodating recess 72a. The flange portion 72b is formed, and the LED substrate 60 can be slid and inserted into the substrate housing recess 72a from one end portion in the longitudinal direction of the unit body 70 by the substrate housing recess 72a and the flange portion 72b. A groove 73 is formed. According to such a lighting fixture 1 and the LED light source unit 50, the unit can be simply inserted and slid into the insertion groove 73 without using an attaching screw or the like for attaching the LED substrate 60 to the unit body 70. Since the LED substrate 60 can be attached to the main body 70, the assembly of the LED light source unit 50 can be facilitated. Further, according to the unit main body 70 in which the insertion groove 73 is formed, for example, by a locking claw formed by cutting and raising a part of the bottom surface portion, such as an attachment member of a light source unit disclosed in Patent Document 1. Compared with what supports an LED board, while being able to simplify the structure of the unit main body 70, heat dissipation can be improved.

  Moreover, since the LED light source unit 50 which concerns on this embodiment is attached to the lighting fixture main body 10 by the V-shaped latching spring 80, it can be easily attached without using a tool etc. In particular, the V-shaped locking spring 80 according to the present embodiment is formed by bending a portion from the intermediate portion 81 to each of the tip portions 82d and 84d upward, left and right, and forward (front side). Thereby, compared with the case where the part from the intermediate part 81 to each front-end | tip part 82d, 84d is formed linearly, the opening distance of the left piece part 82 and the right piece part 84 (tip part 82d of the left piece part 82). And the tip 84d of the right piece 84) can be widened, and the height of the V-shaped locking spring 80 can be suppressed, so that it is possible to reliably prevent the spring receiver 24 from coming off. In addition, the entire lighting fixture 1 can be made thinner.
