INFRARED LIGHT IRRADIATION LAMP FOR AUTOMOBILE

Japanese Patent JP3920052

B2

PROBLEM TO BE SOLVED: To provide an infrared light irradiation lamp relatively thinning red light emission of a front lens to prevent lighting of the lamp from being misconceived as a tail lamp and a stop lamp, by making a peripheral edge part of the lens emit white light and making slight outgoing of white light from in the vicinity of a lens central part.
SOLUTION: In this infrared light irradiation lamp, comprising a vessel-shaped lamp body 12, a lens 14 assembled to a front opening part of the lamp body 12 to partition a lamp chamber in cooperation with the lamp body 12, a reflector 16 provided inside the lamp body 12, a light source 18 provided in the forward of the reflector 16, and an infrared light transmissive film 22 reflecting a visible light component of make an infrared light component transmit, an infrared light transmissive film non-formed region 24 is provided in the external periphery of the infrared light transmissive film 22, light source light not transmitting the infrared light transmissive film 22 is guided to a peripheral edge part 14a of the lens, the peripheral edge part 14a in a region emitting red light of the lens 14 emits white light, red light emission is relatively thinned.
