<P>PROBLEM TO BE SOLVED: To provide an infrared light irradiating lamp, lighting of which is not mistaken as a tail lamp or a stop lamp due to a red light emission from a front lens being relatively weakened, by emitting a small visible light of a light volume not becoming a glare light from a peripheral edge of a convex lens. <P>SOLUTION: With the infrared light irradiating lamp for the automobile provided with a light source unit U with a convex lens 40 integrated through a lens holder 30 in front of a reflector 20 with a light source 22 inserted and having an infrared light transmitting film 46 fitted on a rear face of the convex lens, a region 48 where an infrared light transmitting film is not formed is arranged at an outer periphery of the infrared light transmitting film 46, by which, a white visible light counteracting a red light emission of the convex lens 40 is made emitted from a periphery edge part 40a of the convex lens but a visible light with a high energy density is shielded by a light-shielding member 34 fitted at the back of the region 48 where the infrared light transmitting film is not formed, and only the visible light reflected and attenuated by the infrared light transmitting film 46 with a lowered energy density is guided to the region 48, so that the visible light emitted from the periphery edge part 40a of the convex lens with an adjusted light volume will not become a glare light. <P>COPYRIGHT: (C)2004,JPO |
