Summary of the invention
In view of this, technical problem to be solved by this invention is to provide a kind of simple to operate, safe and reliable vehicle high-low beam light regulating system that implementation cost is lower.
The object of the present invention is achieved like this:
The distance-light regulating system of automobile-used laser lighting provided by the invention, comprise dipped headlights lamp optical system, high beam lamp optical system, laser instrument, photoswitch and controller, described laser instrument exports photoswitch to after optically-coupled, described photoswitch exports input laser respectively to the dipped headlights illumination optical system high beam lamp optical system of unifying under the control action of controller, realizes car and throws light on outward.
Further, described laser instrument is for providing the exciting light sources of blue light.
Further, before described dipped headlights illuminator, be provided with the fluorescence transition material for input blue light being converted to the spectrum that can be used for road lighting.
Further, before described high beam illuminator, be provided with the fluorescence transition material for input blue light being converted to the spectrum that can be used for road lighting.
Further, the laser that described laser instrument produces imports the dipped headlights lamp optical system for laser intensity being converted to the light distribution of lower beam illumination requisite space through coupling fiber.
Further, the laser that described laser instrument produces imports the high beam lamp optical system for laser intensity being converted to the light distribution of far lighting requisite space through coupling fiber.
The invention has the advantages that: the present invention utilizes laser as automobile-used light source, has the many merits of laser lighting, as stronger in illumination, light type can be controlled accurately, rapidly and safely, and energy consumption power is little, improves the energy consumption level of pure electric vehicle type, more energy-conservation, design is free etc.; Adopt optical fiber to carry out leaded light simultaneously, because optical fiber can carry out suitable bending, light source can be placed on be convenient to heat radiation, install and the position of maintenance, cause thereby avoided in LED headlamp cooling system must be placed in chip rear the problem that overall structure is bigger than normal and radiating efficiency is not high, in the design of car inner structure, there is high degree of flexibility and strong vibration resistance; Distance-light can not opened simultaneously, in conjunction with optical fiber light-guiding system, by this system, dipped headlights and high beam is shared to a set of laser instrument, saves interior space.The present invention adopts the switching of photoswitch to realize the conversion of dipped headlights and high beam, convenient and swift.
Other advantage of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating below, or can be instructed from the practice of the present invention.The objects and other advantages of the present invention can be passed through description below, claims, and in accompanying drawing, specifically noted structure realizes and obtains.
