Abstract

The invention provides a laser conduction device, and belongs to the technical field of laser illumination. The laser conduction device comprises a laser light source, a polygon prism, a focusing lens, a fluorescence conversion device and a beam shaper, wherein the optical centers of the polygon prism, the focusing lens, the fluorescence conversion device and the beam shaper are located on the same straight line, and a light beam output by the laser light source is incident on a focusing lens after passing through the multi-angle reflection of the polygon prism; the focusing lens focuses an adjusting light beam obtained through the multi-angle reflection is incident into the fluorescence conversion device so as to excite the fluorescence conversion device to generate an excitation light beam, and the excitation light beam is mixed with a focused light beam incident by the focusing lens to form a white light beam; and the white light beam is incident to the light beam shaper, the lightbeam shaper is used for shaping and adjusting the white light beam into a preset light spot and then uniformly emits the light spot. While the laser conduction and light spot forming are enabled to bemore accurate by the laser conduction device, each element is arranged in a straight line, so that the automobile lamp of the laser conduction device is smaller and compact in size, and installationand maintenance can be easily carried out.

Description

technical field [0001] The invention relates to the technical field of laser lighting, in particular to a laser transmission device. Background technique [0002] With the rapid development of the modern social economy, the number of cars in all countries in the world has increased rapidly. Among them, the growth rate of the number of cars in my country is almost above 10%. And sales are growing explosively. The increase in vehicles has brought greater pressure on traffic safety, and people are paying more and more attention to the quality and safety of vehicles. Vehicle headlights and other lighting devices play an important role in ensuring the driving safety of vehicles. Therefore, the headlight lighting system has also developed rapidly with the development of automobile technology. It only takes a few years from HID to LED, and the life of the car lights has changed from halogen lamps From 1000 hours to 5000 hours of LED lights, the power consumption is also reduced fr...
