Summary of the invention
In view of this, technical problem to be solved by this invention provides a kind of simple to operate, safe and reliable vehicle high-low beam light regulating system that implementation cost is lower.
The objective of the invention is to realize like this:
The far and near 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; Said laser instrument exports photoswitch to after optically-coupled; Said photoswitch will be imported laser and export the dipped headlights illumination optical system high beam lamp optical system of unifying respectively under the control action of controller, realize that car throws light on outward.
Further, said laser instrument is the exciting light sources that blue light is provided.
Further, be provided with the fluorescence transition material that is used for the input blue light is converted into the spectrum that can be used for road lighting before the said dipped headlights illuminator.
Further, be provided with the fluorescence transition material that is used for the input blue light is converted into the spectrum that can be used for road lighting before the said high beam illuminator.
Further, the laser of said laser instrument generation imports the dipped headlights lamp optical system that is used for laser intensity is converted into the light distribution of lower beam illumination requisite space through the optical fiber coupling.
Further, the laser of said laser instrument generation imports the high beam lamp optical system that is used for laser intensity is converted into the light distribution of far lighting requisite space through the optical fiber coupling.
The invention has the advantages that: the present invention utilizes laser as automobile-used light source, has numerous advantages of laser lighting, and is stronger like illumination; The 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 freedom 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 the position of dispelling the heat, installing and keeping in repair; Cause the problem that overall structure is bigger than normal and radiating efficiency is not high thereby avoided in the LED headlamp cooling system must be placed in the chip rear, in the design of car inner structure, have high degree of flexibility and strong vibration resistance; Far and near light can not opened simultaneously, in conjunction with the optical fiber light-guiding system, with dipped headlights and the shared cover laser instrument of high beam, saves interior space through this system.The present invention adopts the switching of photoswitch to realize the conversion of dipped headlights and high beam, and is convenient and swift.
Other advantage of the present invention, target and characteristic will be set forth in specification subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from practice of the present invention, obtain instruction to investigating of hereinafter.Target of the present invention and other advantage can be passed through following specification, claims, and the structure that is particularly pointed out in the accompanying drawing realizes and obtains.
