Abstract
An infrared irradiation lamp having a lamp housing S formed by a Lamp body and a front lens , a reflector provided in the lamp body , a bulb inserted and attached into a bulb insertion attachment hole of the reflector and provided ahead of the reflector , and a cylindrical globe for infrared light formation which is provided to cover the bulb and serves to shield a visible light and to transmit only an infrared light, wherein a metallic bulb holder having a radiation fin extended to the back of the reflector is provided between the bulb insertion attachment hole and a mouth piece of the bulb . Heat generated by turning on the bulb is transferred to the bulb holder and is radiated from the radiation fin provided on the back of the reflector to a space provided on the back of the reflector so that the inside of the globe is not filled with the heat. Thus, it is possible to avoid various problems caused by an increase in the temperatures of the bulb and the globe for infrared light formation.
