Internally illuminated lighting devices are often used for relatively small internally illuminated signboards and the like. On the other hand, when this internal illumination type lighting device is used as a lighting fixture, the front panel is enlarged. Here, if an artificial marble is used as the front panel, the pattern can be raised and the design can be enhanced. For example, floor-to-ceiling height and using an internally lit lighting system results in a large front panel. However, in the case of an internally illuminated lighting device, it is necessary to separate the front panel from the main body of the internally illuminated lighting device for maintenance of the light emitter. In particular, when a large area of artificial marble is used as the front panel, the weight and size are increased, making it difficult to move and maintenance of the light emitters provided on the rear surface of the front panel.

In order to solve the above problems, the internal lighting equipment is provided between the upper structure and the lower structure. a light transmitting body fixed between the upper structure and the lower structure; a light emitting body for illuminating the light transmitting body; and a rear plate behind the light emitting body between the upper structure and the lower structure. and a box having side plates on both sides of the light emitter, a top plate connecting upper ends of the side plates on both sides, and a bottom plate connecting lower ends of the side plates on both sides, wherein the box A body is provided behind the translucent body so as to be slidable in the horizontal direction.

The present invention provides an internally illuminated facility that can realize an illumination environment in which light is emitted through a translucent body and that is easy to maintain.

The shielding plates 221 and 231 are made of a material that is relatively softer than the material of the side plates 22 and 23 . The shielding plates 221 and 231 are arranged in a shape that fills the gap between the side plates 22 and 23 and the front panel 10 . Even when the shielding plates 221 and 231 come into contact with the front panel 10, they function as cushioning materials so as not to damage the front panel 10. - 特許庁

As a result, as shown in FIG. 1, the roller 262 can be slid within the roller receiver 261 to slide the light emitter storage box 20 to the left.

A horizontal end of the roller receiver 261 is closed by a screwed lid 263 . During maintenance, the roller receiver 261 and the roller 262 can be separated by unscrewing the cover 263 .

FIG. 4 is a rear view of the light emitter storage box 20. FIG. A round drop 251 is provided in the lower central portion of the rear plate 26 . When the light-emitting body storage box 20 is arranged on the back surface of the front panel 10, the dropout 251 is fitted into the receiving hole f11 provided in the floor F1. As a result, the position of the light emitter storage box 20 is fixed.

In addition, a power supply unit PU1 for adjusting voltage and current is arranged in the light emitter storage box 20 . As the power supply unit PU1, a power supply device with a commercial voltage (115 V) input, a rated input current of 1.1 A, a rated output voltage of 24 V, and a maximum output current of 4 A is used to supply power to the plurality of light emitters L1. .
