Abstract
An infrared light irradiation lamp for an automobile comprises a lighting chamber S formed by a lamp body and a front lens , a reflector provided in the lamp body , a light source provided ahead of the reflector , a cylindrical globe for infrared light formation provided to cover the light source and serving to shield a visible light and to transmit only an infrared light and a globe moving mechanism for moving the globe , the globe moving mechanism being capable of switching a lamp function into an infrared light irradiation configuration in which the globe covers the light source and a visible light irradiation configuration in which the globe is moved forward from the light source , wherein power regulating means is provided on a power supply path reaching the light source and a power supplied from the light source at time of infrared light irradiation is regulated to be lower than a power supplied from the light source at time of visible light irradiation. The amount of heat generated from the light source covered with the glove is reduced so that the inside of the glove does not have such a high temperature that the infrared ray transmission characteristic of the glove and the lifetime of the light source are not adversely influenced.
