[Action]

 According to the structure of the present invention, since the shape of the light-transmitting cover is larger than that of the brim of the instrument body, it is not necessary to provide a conventional brim concealing portion in the frame, and the appearance is improved. In addition, the packing provided on the upper surface of the peripheral edge of the translucent cover hits the brim, which serves as a buffer for the translucent cover, and the packing hides the brim so that the instrument body cannot be seen through the translucent cover. In addition, the light that has passed through and reflected from the translucent cover is emitted from the peripheral edge of the translucent cover, but since it is a diffused light emitting surface and the ceiling surface is diffusely illuminated, there is no shadow on the ceiling surface, and there is no unevenness on the ceiling surface or the ceiling. The gap with the surface is not noticeable and the light leakage is not noticeable. Furthermore, since the packing is in contact with the brim and the translucent cover is not in contact with the ceiling surface, even if a ceiling cloth or the like is provided on the ceiling, there is no heat effect and the ceiling cloth, etc. does not discolor. Also, there are no marks such as dust on the frame.

【Example】

 An embodiment of this invention will be described with reference to FIGS. That is, this illuminating device has a fixture body 1, a frame 2, a translucent cover 3, and a packing 4. The instrument body 1 is embedded in the embedding hole 6 with a brim 7 that engages with the edge of the embedding hole 6 in the ceiling 5 in the opening 8. This instrument main body 1 is a heavenly cylinder as an example, and is attached by projecting a mounting metal fitting (not shown) from the instrument main body 1 to the back surface of the ceiling. Further, a conical reflector 9 is attached to the lower surface of the top portion, and a lamp 10 is arranged inside the reflector 9 via a lamp socket (not shown). Further, a pair of locking claws 15 are provided at the opposite positions on the inner surface.

The frame 2 has a cylindrical shape having a cover locking portion 12 on its inner surface, and is attached to the instrument body 1 so as to fit into the opening 8. This frame 2 has a ring shape as an example, has a cover pressing portion 11 cut inward and raised at the upper end, has a cover locking portion 12 folded back inward at the lower surface, and has a pair of attachments on the outer peripheral surface. The lower portion of the magic spring 14 is attached to the attaching portion 13 by having the portion 13. As shown in FIG. 2, the magic spring 14 is formed by bending a wire spring into a substantially rhombus shape, forming an inwardly bent portion at the upper end bent portion, and bending the lower end portions at both ends to be attached to the mounting portion 13. When the upper bent portion is pushed through the pair of locking claws 15 of the instrument body 1 and pushed up, the side portions of the magic spring 14 are gradually pressed so as to become thin, and when the side bent portions pass through the locking claws 15, the magic spring 14 is pressed. A biasing force that pulls up the frame 2 upward is generated by a spring force that causes the side portions of the frame to spread, and the frame 2 is pushed up into the instrument body 1 by this biasing force. Reference numeral 19 is a connecting portion of the frame 2.

The translucent cover 3 has a shape larger than a collar and has an engaging portion 16 that engages with the cover engaging portion 12 on the upper surface, and also has a diffused light emitting surface 17 on at least the upper surface of the peripheral portion 20. . The translucent cover 3 is made of acrylic resin or glass. In the embodiment, the ring-shaped portion 21 is erected on the upper surface of the translucent cover 3, and the peripheral groove 18 is formed on the outer peripheral surface thereof to form the engaging portion 16, and the peripheral groove 18 is provided with the cover locking portion 12. It is inserted and engaged with the engaging portion 16. Further, the diffuse translucent surface 17 is formed by erasing and finishing the surface from the upper surface to the lower surface of the peripheral edge portion 20 and diffusing the surface. Q indicates a light beam of diffused emission.

The packing 4 is disposed inside the diffused light emitting surface 17 on the upper surface of the translucent cover 3, contacts the flange 7, and hides the flange 7. The embodiment has a ring shape and is arranged from the peripheral groove 18 to the front side of the peripheral edge portion 20. This prevents the translucent cover 3 from being scratched by the cover locking portion 12 of the frame 2 and also prevents the frame 2 from being seen through the translucent cover 3.

According to this embodiment, since the shape of the translucent cover 3 is larger than that of the brim 7 of the instrument body 1, it is not necessary to provide the conventional brim concealing portion in the frame 2, and the appearance is improved. Further, the packing 4 provided on the upper surface of the peripheral portion 20 of the translucent cover 3 hits the brim 7, which serves as a buffer for the translucent cover 3, and the packing 4 conceals the brim 7 so that the translucent cover 3 The instrument body 1 cannot be seen through. The light transmitted / reflected from the transparent cover 3 is emitted from the peripheral portion 20 of the transparent cover 3, but the diffused light emitting surface 17 is provided. Since the ceiling surface is diffusely illuminated, the ceiling surface is not shaded and the ceiling surface is not shaded. The unevenness and the gap with the ceiling surface are not noticeable, and the light leakage is not noticeable. Further, since the packing 4 is in contact with the brim 7 and the translucent cover 3 is not in contact with the ceiling surface, even if a ceiling cloth or the like is provided on the ceiling 5, there is no heat effect and the ceiling cloth or the like discolors. Never. That is, the contact portion between the instrument body 1 and the ceiling surface is the same as the conventional one, but it is not conspicuous because it is located deeper than the peripheral edge portion 20 of the translucent cover 3.

Further, no marks such as dust on the frame 2 are left. In this regard, conventionally, when the position of the frame 2 was displaced during the replacement of the lamp, marks of dirt on the dust were conspicuous, and it was extremely unsightly. The diffusion light emitting surface 17 of the translucent cover 3 may be provided on the entire surface.
