Japanese Patent Laid-Open No. 2003-197013 JP 2002-21309 A JP 2002-150812 A JP 2002-166778 A In the case of using a heat ray as disclosed in JP-A-2005-122978, the transparent plastic portion to which the irradiated light hits cannot pass light that prevents the passage of light according to safety standards, and the internal air by the carbon-based exothermic heater inside In the case of overheating, the shape of the heating heater hinders light irradiation and may not pass the safety standards for road transport vehicles. In the case of infrared, when installed at the front in the lights, the red color basically does not pass the safety standards for road transport vehicles. “Headlight etc. Article 32 (2) (5) The color of the headlight is white or It must be pale yellow and all of them are the same. " Conventionally, the rear glass has been fitted with heat rays, but the headlamps were not installed because of the safety standards for road transport vehicles as described above. The patent to be acquired this time is a transparent film heater. Thus, heat can be uniformly and efficiently distributed without hindering the irradiation light of the headlamps and other lamps at all, and ice and snow that has landed on the headlamp translucent plastic portion can be efficiently removed.

      However, with the conventional illuminator alone, snowfall on the surface of the illuminator during snowfall and the night vision becomes extremely inconvenient and is very inconvenient.

      By installing a heating element in the casing of the railway vehicle illuminator headlamps, tail lamps, fog lights, direction indicators, etc., in the casing, transmissive case, or shading plate, the snow that accumulates on the top of the illuminator is melted. It can be removed, and the ice and snow adhering to the translucent case of the illuminator and the ice and snow accumulating on the light shielding plate can also be melted.

By installing a heating element in the casing, translucent case, or shading plate in the casing part of the lighting body such as the headlight, the tail lamp, the fog lamp, and the direction indicator, the snow falling on the upper part of the lighting body is melted. It can be removed and the ice and snow attached to the translucent case of the illuminator and the ice and snow that accumulates on the light shielding plate can be melted.

      A lane indicator lamp illuminator headlamp buried in the road and a illuminator by providing a heating element in the casing, translucent case part or light shielding plate in the casing part of the illuminator such as a tail lamp, fog lamp or direction indicator The snow falling on the top can be melted and removed, and the ice and snow attached to the translucent case of the illuminator and the ice and snow that accumulates on the shading plate can also be melted.

      Warning board used for road works Lighting body headlamps and tail lamps, fog lights, turn indicators, etc., by placing a heating element on the casing, translucent case, or shading plate, it gets on top of the lighting body Can melt and remove snow, and can also melt ice and snow adhering to the translucent case of the illuminator and ice and snow that accumulates on the light shielding plate.

      By installing a heating element on the casing, translucent case, or shading plate of the lighting body headlamp of the crossing breaker and the lighting body of the tail lamp, fog lamp, direction indicator, etc. It can be melted and removed, and it can melt ice and snow adhering to the translucent case of the illuminator as well as ice and snow that accumulates on the shading plate.
