Problems solved by technology

Therefore, it has been confirmed that, for example, heat generated from a halogen lamp as a visible light source is stuffed inside the infrared light-transmitting sphere, thereby shortening the life of the light source or the infrared-light transmitting sphere, that is, creating a shield that reduces the amount of light, And thermally aging the infrared light-transmitting multilayer film

Abstract

The infrared irradiation lamp comprises: a lampshade (S) made of a lamp housing (12) and a front lens (14), a reflector (16) arranged in the lamp housing (12), a reflector (16) inserted and connected to the reflector ( 16) the bulb is inserted in the connection hole (13) and the bulb (20) arranged in front of the reflector (16), and a bulb (20) which is arranged to cover the bulb (20) and is used to shield visible light and only pass through infrared light for generating A cylindrical sphere (30) of infrared light, wherein a heat sink (68) extending to the back of the reflector (16) is set between the bulb insertion hole (13) and the socket piece (21) of the bulb (20) ) metal bulb holder (60). The heat produced when bulb (20) is energized is transferred to bulb holder (60), and dissipates to the space formed behind reflector (16) from the heat sink (68) that is arranged on reflector (16) back, makes the heat Not stuffy inside the sphere (30). Therefore, it is possible to avoid various problems caused by temperature rise of the bulb (20) and the sphere (30) for generating infrared light.

Description

technical field [0001] The present invention relates to an infrared irradiation lamp for automobiles which is installed on automobiles and irradiates the front of the vehicle with infrared light, and more particularly, relates to an infrared irradiation lamp for automobiles which has an The ball formed by the infrared light of the bulb as the light source produces an infrared structure, and the infrared illuminating lamp is also shared with a CCD camera sensitive to near-infrared light. Background technique [0002] For example, this type of lamp has such a structure that there is a visible light source and a reflector in a lamp socket composed of a lamp housing and a front lens, and a reflector coated with an infrared light-transmitting multilayer film is provided for shielding the visible light source. The infrared light transmitted through the surface of the sphere in the light source, the infrared light transmitted through the sphere is reflected by the reflector, then p...
