Abstract

PROBLEM TO BE SOLVED: To obtain a luminair which tends not to display the lamp image, by facing a lamp to one end of an optical fiber, to lead outgoing light from another end to an illuminating part having a reflecting plate and a light transmitting panel. SOLUTION: A light source part 1 has a lamp 3, and optical fiber groups 4 and 5 wherein one end is facing to the lamp 3 and lamp light is incident from the end. The other ends 4a and 5a of the respective optical fiber groups 4 and 5 are alternately arranged in a horizontal direction in accordance with respective reflecting plates 14a-14c. A light transmitting panel 15 has a display surface for displaying light by light transmission. The light of the lamp 3 passes through the optical fiber groups 4 and 5 to be incident into the reflecting plates 14-14c, and reflected light by the reflecting plates transmits the light transmitting panel 15. Since the reflected light is irradiated to the light transmitting panel 15, an illuminating effect can be obtained which is difficult to display a lamp image on the light transmitting panel, and suitable for a display content. The apparatus structure of an illuminating part 2 can be constituted as a closed specification, thereby eliminating maintenance and inspection work.

Further, since the plurality of reflectors 14a to 14c are provided, it becomes easy to respond to the size of the translucent panel 15 and the display content displayed on the translucent panel 15, and the shapes of the reflectors 14a to 14c. By setting the number of sheets and the number of sheets, efficient specification setting can be performed. The plurality of reflectors 14a to 14c are arranged adjacent to each other so that the rear surface of one reflector closer to the translucent panel 15 and the reflective surface of the other reflector separated from the translucent panel 15 face each other. The optical fiber groups 4 and 5 are arranged close to the rear surface of the one reflection plate on the side closer to the translucent panel 15 and toward the reflection surface of the other reflection plate.
Direct light from 5 to the translucent panel 15 is blocked, and only the other reflecting plate is irradiated, so that the lamp image can be avoided as much as possible and the uniformity of the brightness of the display surface can be improved.
Moreover, the illumination unit 2 is not enlarged.

Further, since the translucent panel 15 has a display surface for translucent display, various displays such as road signs can be displayed. In addition, the optical fiber groups 4 and 5 are connected to the respective reflection plates 14a-1.
4c are alternately arranged and the lamps 3 are provided corresponding to the optical fiber groups 4 and 5, so that even if one of the lamps 3 goes out due to its life, the remaining lamps 3 can supply light until maintenance is completed. Moreover, the display surface can be uniformly illuminated, and even if there are many variations in the inspection and maintenance cycles due to the lamp life, the display surface will not be partially turned off.

Further, since the cutting sheet 33 is located between the transparent light transmitting material 31 and the milky white light transmitting material 32, the cutting sheet 33 is not peeled off by external stress and is not damaged. Further, the transparent panel 15 can be easily cleaned, and since a plurality of transparent materials are laminated, the transparent panel 15 can be prevented from being deformed. In this respect, in the conventional example shown in FIGS. 19 and 20, the display surface was damaged by external force, dirt was attached to the cut character portion, and cleaning was difficult.

The other ends 4a, 5 of the optical fiber groups 4, 5
