【Example】

 An embodiment of this invention will be described with reference to FIGS. That is, this illuminating device has a fixture body 1, a reflection plate 2, a pair of lamp sockets 3, and a pair of socket covers 4. The instrument body 1 has a reflection plate attachment receiving portion 6 on the lower surface and a fall prevention piece 5 on one side portion. The instrument main body 1 of the embodiment is a rectangular flat plate with side pieces 9 hanging down on both sides thereof. The socket bases 10 are attached to both ends of the instrument main body 1 by the attachments 11, and the upper end attachment portion of the lamp socket 3 is attached to the socket base 10. Is installed. The fall-preventing piece 5 is attached to one side piece 9 with a screw 12, and the tip end thereof is extended to the side of the instrument body 1. The reflection plate attachment receiving portion 6 is formed by forming a narrow portion 21 of a predetermined width b at both ends of a substantially inverted U-shaped leaf spring, and extending a guide portion 13 outward at the tip thereof. Is attached to the substantially central portion of the instrument body 1 by a fixture 14. Reference numeral 18 denotes an end plate, which is attached to the instrument body 1 with a screw 19. 20 is a ballast.

The pair of lamp sockets 3 are vertically installed at both ends of the appliance body 1 so that the lamp pin mounting portions 15 face each other. The pair of socket covers 4 covers the lamp pin mounting portion 15 of the lamp socket 3 and covers the base of the straight tube lamp 16 mounted on the lamp socket 3. The socket cover 4 of the embodiment has a cylindrical shape.

The reflection plate 2 has an attachment portion 8 to be attached to the reflection plate attachment receiving portion 6, and a hook portion 7 that is hooked on the fall prevention piece 5 in a state where the attachment portion 8 is disengaged from the reflection plate attachment receiving portion 6.

The reflector 2 of the embodiment has a substantially Fuji shape, and both sides thereof are folded inward and one side thereof is also used as the hook portion 7. As shown in FIG. 2, a horizontal rod having a constant width c is used as an example of the mounting portion 8. The horizontal rod is a rectangular flat plate, and both sides are folded inward. The width c is narrower than the predetermined width b of the narrow portion 21 of the reflector mounting portion 6 (b <c). Therefore, when the mounting portion 8 is pushed in, the narrow portion 21 is expanded along the guide portion 13 and enters the inner portion to restore the reflection plate attachment receiving portion 6 so that the reflection plate 2 is in the attachment state. On the contrary, when the reflection plate 2 is strongly pulled, the mounting portion 8 again crosses over the narrow portion 21 and separates from the reflection plate mounting receiving portion 6.

According to this embodiment, the reflector plate 2 is attached to the lower surface of the instrument body 1 by attaching the attachment portion 8 of the reflector plate 2 to the reflector plate attachment receiving portion 6 of the instrument body 1. When the reflection plate 2 is removed from the reflection plate attachment receiving portion 6 and lowered, both ends are locked to the socket cover 4 and the hook portions 7 are locked to the fall prevention piece 5, so that the reflection plate 2 is prevented from falling. When the reflector 2 is removed, the fall prevention piece 5 is removed from the hook portion 7 while being mounted on the fall prevention piece 5 and the socket cover 4, and the instrument body 1 is moved to one of the lateral directions. It can be easily removed. Therefore, compared to the conventional example, it is possible to surely prevent the fall without increasing the height of the instrument, and the construction becomes easy.

Moreover, in this embodiment, a leaf spring is used for the reflection plate attachment receiving portion 6, the attachment portion 8 is attached by pushing it in, and the attachment portion 8 can be removed by pulling strongly, so that it can be attached and detached with a one-touch operation. The construction will be further reduced. The fall prevention piece 5 may be integrally formed with the side piece 9 of the instrument body 1 as shown in FIG. Further, the mounting portion 8 of the reflecting plate 2 may be a screw and the reflecting plate mounting receiving portion 6 may be a screw hole.
