The second fixing portion 91 has a screw insertion hole 910 passing through the center in the longitudinal direction (see FIG. 3).

  Next, the assembly procedure of the light source unit 2 will be described. First, the operator stores the LED module 3 supported by the support member 4 in the case main body 6 and fixes the support member 4 to the case main body 6 by the mounting bracket 61.

  Subsequently, the operator inserts the screw 75 into the insertion hole 701 provided in the bottom of the recess 700 of the end member 7 and screws the screw 75 into the screw hole 1000 of the first fixing piece 100 to fix the fixing bracket 10. Is attached to the end member 7. Then, the operator puts the end member 7 attached with the waterproof packing 8 inside the peripheral wall 71 on the end portion of the case body 6 so that the fixing bracket 10 is housed in the case body 6.

  Finally, the operator fastens the first fixing portion 90 of the fixture 9 and the second fixing piece 101 of the fixture 10 to the case main body 6 together with the fixing screw 93, so that the end member 7 and the fixture 9 are fixed. Can be fixed to the case body 6 (see FIG. 3). As described above, the light source unit 2 of the present embodiment is assembled. The electric wire connected to the power supply device is drawn out of the waterproof case 5 through an insertion hole (not shown) provided in the peripheral wall of the case body 6 and a waterproof bushing (not shown).

  Next, the assembly procedure of the lighting fixture A will be described. The operator stores the upper part of the light source unit 2 above the light distribution unit 60 in the recess 11 of the instrument body 1. Then, the operator has inserted through the screw insertion holes 910 of the second fixing portion 91 of the fixture 9 into the screw holes 13 provided on the outer side along the longitudinal direction of the recess 11 on the lower surface of the instrument body 1. Screw 93 is screwed (see FIG. 6). In this way, the lighting fixture A is assembled by fixing the light source unit 2 to the fixture body 1.

  As described above, the light source unit 2 of the present embodiment includes a light source (LED module 3) having one or more solid light emitting elements (LEDs 30), a support member 4 that supports the light source, and a support member 4 that supports the light source. And a waterproof case 5 housed inside. Further, the light source unit 2 of the present embodiment includes a fixture 9 for attaching the waterproof case 5 to the fixture body 1 of the lighting fixture A. The waterproof case 5 is formed in a cylindrical shape having an opening at least on one end side, and a case main body 6 in which a wall facing the light source is formed of a light-transmitting material, and an end member 7 for closing the opening of the case main body 6 The waterproof packing 8 closes the gap between the case body 6 and the end member 7. The fixture 9 includes a first fixing portion 90 that is fixed to a surface of the case body 6 that does not face the light source, a second fixing portion 91 that is fixed to the instrument body 1, a first fixing portion 90, and a second fixing portion 91. And a connecting portion 92 for connecting the two. The connecting portion 92 protrudes along the end member 7 in a direction approaching the front wall of the case body 6 and is configured to connect the second fixing portion 91 to the front end.

  The light source unit 2 of the present embodiment is configured as described above, and since the light source unit 2 is screwed to the instrument body 1 via the fixture 9, the instrument is compared with a conventional mounting structure using a mounting spring. The mounting strength of the light source unit 2 with respect to the main body 1 can be improved. Moreover, screwing of the fixture 9 to the instrument body 1 can be performed from the front of the instrument body 1. As a result, the light source unit 2 of the present embodiment can improve the mounting strength of the light source unit 2 with respect to the instrument body 1 while suppressing a decrease in workability of the mounting work.

  Here, as shown in FIG. 7, when the end member 7 is screwed to the case main body 6 on a surface that does not face the connecting portion 72, the fixing screw 75 in the state where the light source unit 2 is attached to the instrument main body 1 is used. Is exposed to the outside of the recess 11 of the instrument body 1. Therefore, there exists a possibility that the designability of the external appearance of the lighting fixture A may fall.

  On the other hand, in the light source unit 2 of the present embodiment, the end member 7 is configured to be screwed to the case body 6 on the surface facing the connecting portion 72. Further, the connecting portion 72 is configured to connect the second fixing portion 71 in front of the screwing position to the case body 6 (downward in FIG. 1). Therefore, in the state where the light source unit 2 is attached to the fixture body 1, the head 750 of the fixing screw 75 is hidden in the recess 11 of the fixture body 1. be able to.

  By the way, as for the light source unit 2 of this embodiment, the case main body 6 is formed with the synthetic resin material. And since the light source unit 2 and the lighting fixture A of this embodiment are used outdoors (the shop side), the fluctuation range of atmospheric temperature (air temperature) becomes large compared with the case where it uses indoors, for example. For this reason, the amount of displacement when the case body 6 expands and contracts increases with changes in temperature.

  Therefore, the fixture 9 is preferably configured so as to leave a gap S between the connecting portion 92 and the end member 7 as shown in FIG. The gap S can prevent the end member 7 from interfering with the connecting portion 92 of the fixture 9 when the case body 6 expands.

  Note that the end member 7 in the present embodiment is configured such that the outer surface of the bottom wall 70 facing the opening surface of the case body 6 is a flat surface. For this reason, when the outer surface of the bottom wall 700 of the end member 7 is not flat, for example, the design can be improved as compared with a case where a recess is provided.

  By the way, when the front end surface of the peripheral wall 71 of the end member 7 is formed in a direction substantially orthogonal to the peripheral surface of the case main body 6, most of the wind pressure load received by the front end surface of the peripheral wall 71 separates the peripheral wall 71 from the case main body 6. There is a possibility that the degree of adhesion between the waterproof packing 8, the peripheral wall 71, and the case body 6 may be reduced. That is, when a strong wind such as a typhoon blows, the wind pressure load received by the distal end surface of the peripheral wall 71 of the end member 7 increases and the waterproofness of the waterproof packing 8 decreases.

  On the other hand, in the light source unit 2 of the present embodiment, as shown in FIG. 2, the front end surface (the right end surface in FIG. 2) of the peripheral wall 71 of the end member 7 approaches the case body 6 as it moves away from the bottom wall 70. The inclined surface 710 is inclined in the direction. That is, a part of the wind pressure load received by the inclined surface 710 of the peripheral wall 71 becomes a force that pushes the peripheral wall 71 toward the case body 6, so that the adhesion between the waterproof packing 8, the peripheral wall 71, and the case body 6 increases. The decline in sex is suppressed.

  Instead of screwing the bottom wall 70 of the end member 7, a plate-like projecting piece protruding from the bottom wall 70 along the inner peripheral surface of the case body 6 is formed. Alternatively, the protruding piece may be screwed from the upper front and rear surfaces.
