As shown in FIG. 4, the side portion 232 has a hooking groove 232 a (concave portion) formed such that the cross section is smoothly recessed in a concave shape from the outside to the inside of the translucent cover 230. The term “groove” is because the hooking groove 232a is formed along the longitudinal direction of the translucent cover 230 (FIG. 2A). The hook groove 232a of the first side portion 232 is a first side recess, and the hook groove 232a of the second side portion 232 is a second side recess.

  The operator can easily remove the light source unit 200 from the instrument main body 100 without slipping by hooking a finger on the hooking groove 232a and gripping the side portions 232 on both sides. In addition, if this hooking groove 232a forms a corner | angular part in an outer shell part, it will become easy to catch a finger | toe further and it will become easier to remove the light source part 200 from the instrument main body 100 more.

Embodiment 2. FIG.
The second embodiment is a modification of the side part 232 of the first embodiment. In the second embodiment, the description of the same structure as that of the first embodiment is omitted, and only the characteristic part of the second embodiment is described. FIG. 6 is a cross-sectional view showing a cross section of the light source unit 200 of the second embodiment, and FIG. 7 is a cross-sectional view showing a cross section of the lighting fixture 1000 of the second embodiment. 6 and 7 correspond to FIGS. 4 and 5 of the first embodiment.

The side part 232 of the first embodiment has a hooking groove 232a formed so that the cross section is smoothly recessed in a concave shape from the outside to the inside of the translucent cover 230. On the other hand, the side part 232 of the second embodiment has a hooking convex part 232b formed by protruding in a convex shape in the outer direction of the translucent cover 230. The hooking convex part 232b is formed over the longitudinal direction of the translucent cover 230 similarly to the hooking groove 232a. 6 and 7, the left side 232 is referred to as a first side 232, and the right side 232 is referred to as a second side 232. The hook convex portion 232b of the first side portion 232 is a first side convex portion, and the hook convex portion 232b of the second side portion 232 is a second side convex portion.

  As in the case of the hooking groove 232a, the work difference is determined by gripping the side portions 232 provided on both sides of the translucent cover 230 so that the finger is hooked on the hooking convex portion 232b. The light source unit 200 can be easily removed from the projector. In addition, this hooking convex part 232b may also form a corner | angular part in an outer shell part.

  In addition, although the case where the hook groove 232a of Embodiment 1 and the hook convex part 232b of Embodiment 2 were formed over the full length of the longitudinal direction of the translucent cover 230 was demonstrated, it is an example. The hook groove 232a and the hook protrusion 232b may not be formed over the entire length in the longitudinal direction. It may be partially formed in the longitudinal direction of the translucent cover 230.

  Moreover, although the hook groove part was demonstrated in Embodiment 1, and the hook protrusion was demonstrated in Embodiment 2, you may form both a hook groove part and a hook protrusion.
