Description
Technical field
The present invention relates to a kind of headlight for vehicles, especially a kind of headlight for vehicles with secondary light conversion.
Background technology
Xenon lamp pearl (abbreviation xenon lamp) and LED light source have become the main illuminating source of headlight for vehicles.Along with the fast development of LED lighting technology, because it has advantages of low power consuming, long service life, be not only widely used in the general lighting field of indoor and outdoor, and be used in gradually automobile lamp industry.LED lamp has been used as in the design of headlamp, taillight and indicator of automobile at present.But all kinds of LED car lights that gone on the market are only merely replaced original incandescent lamp, Halogen lamp LED or HID lamp with LED lamp at present, although the long-life that LED lamp is had (10000 hours), irradiation area have good range, this very needs for automobile illuminator.But, there is following problem in the headlamp with LED light source as automobile result of use: the LED lamp as light source only utilizes common packaging technology, does once encapsulation.Due to LED light source belong to compared with on subsection area, give out, there is the photon beam strong compared with high light, under the relatively high 1m of unit, all there is higher ultraviolet light and blue light, particularly the LED light source after common process is the white light source that blue-light excited YAG fluorescent material converts to, in the process that forms white light, can produce rich blue light phenomenon.
The inventor thinks: all headlight for vehicles are not all considered this feature of LED light source in design now.Because headlight for vehicles is to be excited and produced illumination light efficiency by certain voltage and current by xenon lamp pearl and LED light source, and the light of ejaculation after requiring reflect by snoot reaches the illumination of certain setting in certain distance, ensure that with this driver sees the road conditions in front clearly at night.But the light that xenon lamp pearl or LED light source produce belongs to the spot light that light is too concentrated, although by the reflection processing of snoot, but still there is serious glare phenomenon, owing to requiring to meet certain intensity of illumination in certain distance, therefore to having relatively high expectations of light efficiency, therefore there is relatively strong shortwave blue light ingredient in stronger light source.There is very strong dazzling harm to the driver who goes in the same direction in this light beam that contains stronger blue light ingredient, thereby affects driving at night safety
Therefore, when using LED light source as headlight for vehicles light source, seriously ignored the seriousness of this problem.Excessively bright, especially to include blue light headlamp is not only crossed and can be caused by force the excessive phenomenon of dazzle because of light in the time of two car meetings, and can damage mutually the other side driver's eyes; So propose a kind ofly to eliminate excessive blue light, and can effectively overcome and reduce glare phenomenon and be only the development prospect of headlight for vehicles.
Summary of the invention
Object of the present invention: be intended to propose a kind of blue light headlight for vehicles harm, that there is secondary light transformational structure of eliminating as far as possible.
This headlight for vehicles with secondary light transformational structure, comprises base 1, lamp body 2, lampshade 3, LED lamp group, heat abstractor 9 and lens 6, it is characterized in that: on the interior minute surface of described lens 6, applying one deck YAG yellow phosphor coating 8.
As the further improvement to above-mentioned technology, the interior minute surface of described lens 6 is provided with a stratiform and becomes optical thin film 11.
As the further improvement to above-mentioned technology, described lens 6 is for being mixed with the lenticular body 12 of YAG yellow fluorescent powder.
Described electroluminescent lamp group is LED lamp group, and described LED electroluminescent lamp group is separately positioned on the basin type support 4 and heat abstractor front end face of lampshade 3 inner chambers.
Described electroluminescent lamp group is xenon lamp 13, and this xenon lamp 13 is arranged on the center taking basin type support 4 as reflecting surface.
Described YAG yellow phosphor coating 8 and stratiform become optical thin film 11 by polyacrylic resin or mylar or both mixtures, fluorescent material and the compositions of mixtures of other auxiliary agent on a small quantity.
Described YAG yellow phosphor coating realizes secondary encapsulation by new type water coating process, and the YAG yellow phosphor coating of trace spraying comprises the homogeneous mixture of acrylic resin or polyethylene glycol oxide or both mixtures, labile all-transparent dispersant, deionized water and appropriate fluorescent material.
Described YAG yellow phosphor coating 8 realizes secondary encapsulation by water coating process, and the interior application layer of trace spraying comprises the homogeneous mixture of acrylic resin or polyethylene glycol oxide or both mixtures, labile all-transparent dispersant, deionized water and appropriate fluorescent material.
Described polyacrylic resin or mylar or both mixtures and fluorescent material ratio are 100:0.05～100:4.
Described acrylic resin or polyethylene glycol oxide or both mixtures and fluorescent material ratio are 100:0.5～100:4.
This headlight for vehicles with secondary light conversion proposing according to above technical scheme, owing to taking to set up one deck YAG yellow fluorescence coating or one deck and be mixed with at the internal layer of lens the resin film of YAG yellow fluorescent material, or just in the time of the making of molded lens, directly add appropriate YAG yellow fluorescence powder material, thereby make the light beam that headlight for vehicles sends complete the conversion of secondary light before penetrating lens, thereby cause the low band blue light containing in white light that LED luminescence chip produces or xenon lamp to change into as far as possible the white light less to human eye destructive stimulus.Obvious this technical measures are very useful for improving the result of use of headlight for vehicles and reducing harm.
