Embodiment Construction

[0012] A car headlight, such as figure 1 As shown, it includes a laser light source 1 , a fluorescent sheet 2 , a rotating mechanism 3 and a reflector 4 . The fluorescent sheet 2 is fluorescent ceramic glass, the middle part of the fluorescent sheet 2 is connected with the rotating mechanism 3, the fluorescent sheet 2 can rotate under the drive of the rotating mechanism 3, and the rotation axis is perpendicular to the surface of the fluorescent sheet 2; one side of the fluorescent sheet 2 has a laser The light source 1 and the laser light source 1 adopt laser diodes, and the light radiation direction of the laser light source 2 faces the fluorescent sheet 2; During work, the fluorescent sheet 2 rotates driven by the rotating mechanism 3, the laser light source 2 projects laser light to the fluorescent sheet 2, excites the fluorescent material on the fluorescent sheet 2 to generate diffused light, and the diffused light is projected to the reflector 4, and then projected outwar...

Abstract

The invention discloses an automobile headlamp. The automobile headlamp comprises a laser light source, a fluorescent piece, a rotating mechanism, and a reflecting mirror, wherein the central part ofthe fluorescent piece is connected with the rotating mechanism; the laser light source is positioned on one side of the fluorescent piece; and the reflecting mirror is arranged on the other side of the fluorescent piece. The automobile headlamp has the benefits as follows: during work, the fluorescent piece is driven by the rotating mechanism to rotate, the laser light source projects laser onto the fluorescent piece, so as to activate the fluorescent material on the fluorescent piece to generate diffusion light, the diffusion light is projected onto the reflecting mirror on the periphery of the fluorescent piece and further projected outwards; besides, the principle that the laser light source activates the fluorescent material to emit light is fully utilized on the whole structure, the spatial arrangement of laser lamps is greatly simplified, the probability that the fluorescent piece is burnt out is effectively reduced, and a heat dissipating function is achieved at the same time.

Description

technical field [0001] The technical field relates to a lighting appliance, in particular to an automobile headlamp with a new structure. Background technique [0002] Laser Diode (Laser Diode, LD) has the characteristics of high luminous efficiency, small component size, low energy consumption, long life, fast response speed, and low brightness attenuation. In recent years, with the advancement of technology, a large number of technical problems of laser diodes have been solved. It has entered the stage of large-scale application. At present, automobile headlight products using laser light source technology have appeared. Since the laser element can only emit monochromatic light, it is necessary to synthesize multiple monochromatic lights or pass through a fluorescent filter to obtain the required color of light (car headlights generally require white light). In order to adjust the light color and light path to achieve the predetermined effect, most of the existing laser ...
