Technical field
The present invention relates to a kind of automobile-used illumination head lamp system, particularly a kind of laser headlamp spectrum regulating system.
Background technology
Headlamp is claimed " headlight " again, is loaded on automobile head both sides, is used for the illumination of driving at night road; Being out-and-out " heart " for full car light, is the important component part of automobile, and it provides illumination and indication necessary in the running car; At present, traditional automotive lighting often adopts halogen regenerative-cycle headlamp, xenon headlight, and the LED headlight was also more and more universal in the last few years; Except more power saving, life-span are longer; The LED headlight also has many comparative advantages, and from trend, LED replaces halogen or xenon headlight trend of the times comprehensively.Yet no matter adopt which kind of light source, output spectrum is regulated in case can't carry out spectrum after installing by the decision of light source self-characteristic.Reality with the lamp process in, conventional lamp such as xenon headlight are cold white light source, have higher light efficiency, under normal meteorological condition, have good illuminating effect, but wet weather and greasy weather because its penetration power is relatively poor, illuminating effect is had a greatly reduced quality; And halogen tungsten lamp is the warm white light source, and photochromic inclined to one side Huang has higher penetrating power in the greasy weather, but light efficiency and luminous power generally are weaker than xenon headlight during at ordinary times with lamp; The spectrum of LED headlamp then is decided by the performance of its packaged chip and fluorescent material, can not regulate in the use.The output spectrum illumination effect of headlight has considerable influence; And existing car headlamp can't be realized the adjusting of spectrum; Under DIFFERENT METEOROLOGICAL CONDITIONS; Therefore the lighting environment of safety and comfort all need be provided, be badly in need of the regulating system of a kind of simplicity of design, easy to operate and safe and reliable vehicle lights spectrum.
Summary of the invention
In view of this, technical problem to be solved by this invention provides a kind of regulating system of simple to operate, safe and reliable vehicle lights spectrum that implementation cost is lower.
The objective of the invention is to realize like this:
The automobile-used laser head lamp system that spectrum provided by the invention is adjustable; Comprise laser instrument, photoconverter, the illumination optical system controller of unifying; Said laser instrument will expose on the photoconverter with spectrum translation function after will producing one-wavelength laser; Said photoconverter produces the required spectrum of illumination under the switching controls effect of controller, and produces institute's light-dependent type distribution through lamp optical system.
Further, said photoconverter comprises at least two elements with spectrum translation function, and can in light path, freely switch through the mode of mechanical movement.
Further, the core component of said light conversion element is the optical material with fluorescence translation function, can be the host material that is mixed with fluorescent material or light emitting ionic.
The invention has the advantages that: the one-wavelength laser that the present invention adopts photoconverter that laser instrument is produced carries out the spectrum conversion, and this photoconverter can produce the required spectrum of multiple illumination under the switching controls effect of controller, realized the adjusting of laser headlamp spectrum; Satisfied under DIFFERENT METEOROLOGICAL CONDITIONS; The illuminating effect of the output light of headlight utilizes laser as light source, has numerous advantages of laser lighting; Stronger like illumination; The light type can be controlled accurately, rapidly and safely, and is more energy-conservation, design freedom etc.; When regulating output spectrum, because a shared cover lamp optical system can not influence the variation of car light output distribute light type; The adjusting of spectrum is accomplished through the fluorescence light conversion element, does not need the design of light source and light path, and implementation method is simple.
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.
