摘要： PROBLEM TO BE SOLVED: To suppress the number of LEDs as a light source small and to increase the mechanical strength of a light emission surface for use as a surface light emission unit for a road surface while enabling uniform light emission over wide area. SOLUTION: On the internal bottom surface of a base chassis 1 formed in a flat shallow dish shape, a surface light emission body 2 is mounted in contact across a reflecting sheet 5 and this surface light emission body 2 is covered with a transparent cover 3 in contact across a diffusion sheet 6 and a filter sheet 7. An external force applied to the cover 3 can be received by the base chassis 1 through the contact part and the cover 3 and surface light emission body 2 are prevented from being broken to increase the surface strength. Further, a light guide plate 4 and an edge light structure having LEDs as the light source arranged at its end part is used, so uniform surface light emission can be actualized by a small number of LEDs to enable low-cost manufacture.

摘要： PROBLEM TO BE SOLVED: To prevent malfunction of an obstacle detector installed within railroad crossing even in the case where a metal halide lamp using a discharge light emitting lamp is used as a light source of a headlamp of railroad crossing. SOLUTION: A light cut off means for cutting off light in a wave length region where a light receiving element of the obstacle detector arranged along a railway line can receive light is installed in the headlight of the railway rolling stock. For example, the headlight is equipped with: the discharge light emitting lamp 13; a reflector 22 reflecting light emitted from the discharge light emitting lamp 13; and a lens 12 transmitting light reflected with the reflector 22, the light cut off means is composed of a light reflecting membrane 41 formed by applying or vapor-depositing an infrared reflecting coating material reflecting light in the wave length region where light receiving element can receive light, and the light reflecting membrane 41 is formed on the surface of the lens 12. When the railway rolling stock approaches the railroad crossing, the light receiving element is prevented from by outputting a light receiving signal receiving the infrared from the headlight of the railway rolling stock, and a malfunction of not producing an alarm by the output of such a light receiving signal from the light receiving element is prevented, and safety operation of the railway rolling stock is ensured.
