Abstract
The invention relates to the technical field of illumination, in particular to a headlamp and a light reflection, separation and conversion device for the headlamp. The headlamp comprises a light source assembly and a light projection device, and further comprises the light reflection, separation and conversion device. Light emitted by the light source assembly irradiates the light reflection, separation and conversion device and then is divided into light a and light b. The light a and the light b irradiate the light projection device. A dipped headlamp light distribution pattern with light and dark cut-off lines is formed after the light a passes through the light projection device. According to the headlamp, the light emitted by the light source assembly is all used for irradiating a front area after passing through the light reflection, separation and conversion device and the light projection device, that is, in the scheme, all the light of the light source assembly is effectively utilized except for light inevitably lost in the spread process. Therefore, compared with a traditional headlamp with a shading plate for shading, the light utilization rate of the headlamp is greatly increased.
Description
Technical field
The present invention relates to lighting technical field, be specifically related to a kind of headlamp and be separated conversion equipment for the light reflection of this headlamp.
Background technology
In technical field of automobile illumination, national publication GB7454-87 " automotive headlight uses and light adjustment technology is planned ", GB4599-2007 " headlamp luminous intensity distribution performance " and GB4660-2007 " lamps for vehicle silk bulb front fog lamp " propose clear and definite requirement to the luminous intensity of the far lighting of motor vehicle, lower beam illumination and fog lamp and direction of illumination.
For the dipped headlights of headlamp, require that emitted light must form "cut-off"line clearly, and for the formation of this "cut-off"line, mainly adopting shadow shield to carry out this technology of shading at present, its principle is, the light that light source is launched, by arranging shadow shield, some light is blocked, and then form a light and shade region, form a "cut-off"line in penumbra, so, its illuminated area is made to meet the regulation of relevant criterion.
The formation basic theory of above-mentioned "cut-off"line, although be used among current headlamp widely at present, but it still also exists the technological deficiency that can not avoid, be embodied in the problem of its light utilization efficiency, namely, based on above-mentioned principle, the structure of current automobile dipped headlight normally includes light source and for blocking the irradiant shadow shield of light source, due to the existence of shadow shield, the light portion that light source is penetrated is blocked, and then make the region part that is illuminated darker, and another part is brighter, that is, the light that light source sends a wherein part is blocked plate and blocks, do not participate in illumination work, so make the headlamp of current said structure, its light utilization efficiency is not high.
Due to the problem that upper beam utilization rate is not high, its result directly caused is exactly the waste to light source power, namely, in order to reach certain intensity of illumination, need the light source choosing relatively high power, and choose powerful light source due to needs, also just bring many adverse influences to headlamp, such as be unfavorable for the heat radiation of headlamp, make headlamp volume comparatively large and be inconvenient to install etc.
So, based on above-mentioned, need a kind of headlamp that can improve light utilization efficiency at present badly.
Summary of the invention
The object of the invention is to: for the problem that current headlamp light source utilization rate is not high, provide a kind of and can improve the headlamp of light utilization efficiency and be separated conversion equipment for the light reflection of this headlamp.
