Laser LED dual-light-source high-beam car light

Abstract

The invention provides a laser LED dual-light-source high-beam car light and solves the problems that existing high-beam car lights are low in light emitting efficiency, large in light emitting point, not prone to reshape, not far in high-beam illumination, intense in heating, limited in brightness, short in service life, high in cost and the like. The car light comprises a laser light source, a condensing lens, a fluorescence piece, an LED light source, a laser light reflecting cup and an LED light reflecting cup; the laser light reflecting cup and the LED light reflecting cup are mounted in a matched manner to form a paraboloid; a heat dissipation piece is arranged in the paraboloid; a through hole for facilitating passing of laser beams is formed in the side surface of the laser light reflecting cup; a laser, the condensing lens and the fluorescence piece are located in the same straight line direction; and the fluorescence piece and the LED light source are located on the opposite side surfaces of one end of the heat dissipation piece respectively. With the high-beam car light, the cost is reduced, the range which cannot be illuminated by a low-beam car light is included, the illumination distance is 200 m or above, the safety of a motor vehicle running at the high speed is greatly improved, and the high-beam car light is high in practicability, long in service life, high in light emitting efficiency, long in illumination distance, low in cost and suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a high-beam vehicle lamp with laser LED dual light sources. Background technique [0002] The high-beam headlights of motor vehicles are an indispensable accessory in the driving process. The high-beam headlights can improve the line of sight and expand the observation field of vision. On the dark road without street lights, the visual range after turning on the high-beam headlights is much larger Because only the low beam lights are turned on, it is very necessary to turn on the high beam lights when driving at night. [0003] Existing motor vehicle high beam lamps have light sources such as incandescent lamps, halogen lamps, xenon lamps, LEDs, and laser lamps; among them, both incandescent lamps and halogen lamps have problems such as low luminous efficiency and short life; xenon lamps have large luminous points and are not easy to shape , high beam irradiation is not far away, heat ...
