<< Assembling the light source unit 50 >>
Since the light source 5, the holder 9, the heat sink 7, the heat conductive sheet 8, and the optical control member 6 can be unitized as the light source unit 50, the assembly work of the fixture can be divided and performed as a pre-work. Wider width.

The assembly of the light source unit 50 including the light source 5, the holder 9, the heat sink 7, the heat conductive sheet 8, and the optical control member 6 will be described.
(1) First, a light source 5 with one end side of the harness 10 inserted is arranged in the holder 9. At that time, the position of the light source 5 is determined by aligning the curved portion of the substrate positioning portion 93 and the light source substrate 51.
(2) After arranging the light source 5, the harness 10 is pushed into the harness holding portion 981. As a result, the harness 10 is fixed, and stress is prevented from being applied to the connector 53 of the light source 5. After that, the harness 10 is hooked on the harness holding portion 982 and passed through the harness holding portion 983. As a result, it is possible to prevent the harness 10 from being pinched when the heat radiating plate 7 is attached and damage to the coating of the harness 10 due to the edge of the heat radiating plate 7.
(3) After that, the heat conductive sheet 8 is placed on the back surface 512 of the light source substrate 51, and the mounting claw 92 of the holder 9 is inserted into the square hole 73 of the heat radiating plate 7. As a result, the heat radiating plate 7 and the heat conductive sheet 8 can be temporarily fixed to the holder 9. Temporary fixing prevents the light source 5 from coming off and improves workability.
(4) Next, the optical control member 6 is attached to the member arrangement surface portion 920 of the holder 9.

At that time, the concave portion 903 and the convex portion 905 provided on the holder 9 prevent the holder 9 from being unexpectedly detached from the holder 9. By mounting the optical control member 6 by sliding it in the horizontal direction (P2 direction), the weight of the L-shaped rib 901 is applied in the vertical direction in the fixture mounting state. Therefore, unless the L-shaped rib 901 is damaged, the optical control member 6 does not come off the holder 9 and fall.
(5) After the optical control member 6 is attached, the position of the optical control member 6 is fixed by bending the hinge portion 902, the slide becomes impossible, and the optical control member 6 does not come off from the holder 9. As shown in (b) of FIG. 22 and (b) of FIG. 24, the hinge portion 902 has a resin hinge structure integrated with the holder 9, so that the number of parts can be reduced and the cost can be reduced. The hinge portion 902 may be a separate member.
(6) Finally, the assembly of the light source unit 50 is completed by fixing the light source unit 50 to the heat radiating plate 7 from the side of the holder 9 using two screws 911. By fixing with screws 911, the substrate pressing portion 94 of the holder 9 presses the light source substrate 51 against the heat conductive sheet 8 and the heat radiating plate 7 to efficiently dissipate heat.

As shown in FIGS. 19 and 21, when each of the light source 5 and the optical control member 6 has a plurality of types, the combination of the light source 5 and the optical control member 6 completes a plurality of types of the light source unit 50. Further, even when there are a plurality of types of power supply units 4, the same structure has the effect of improving the assembly efficiency of the operator.

<About the vertical movement of the light source unit 50>
As shown in FIGS. 30 to 32, the light source unit 50 is movable in the vertical direction while being fixed to the power supply unit 4 so that the back surface of the substrate faces upward. That is, the light source unit 50 is movable in the vertical direction while being attached to the power supply unit 4 so that the light source faces downward. Movable in the vertical direction means that the light source unit 50 has rattling in the vertical direction in the state shown in FIGS. 30 to 32. Further, the vertical direction is also referred to as a falling direction or a vertical direction.

As shown in FIG. 9, the case 15 of the power supply unit 4 has a pair of bearing portions 155 to which the pair of shaft portions 91a of the holder 9 are attached. As shown in FIGS. 12 and 18, the shaft portion 91a is pushed into the bearing portion 155 in the P5 direction. At this time, the shaft portion 91a is pushed into the bearing portion 155 while the taper portion 911a (FIG. 18) of the shaft portion 91a and the inclined portion 155a of the bearing portion 155 are in contact with each other. As described above, since the taper 911a is formed on the shaft portion 91a and the inclined portion 155a is formed on the bearing portion 155, it is easy to attach the shaft portion 91a to the bearing portion 155.

The positioning portion 97 stops the light source unit 50 at the power supply unit 4 so that the back surface of the substrate faces upward, that is, the light source faces downward, with the shaft portion 91a attached to the bearing portion 155. As shown in FIG. 18, the positioning portion 97 protrudes from the heat radiating plate 7. Further, as shown in FIG. 12, the power supply unit 4 is formed with an elongated hole 166 into which the position fixing portion 97 is inserted.
As shown in FIG. 23, the position stop portion 97 is formed with a stop portion 97a having a large width at the end portion.
