Abstract
The invention relates to an automobile LED front fog lens capable of eliminating chromatic dispersion and a chromatic dispersion eliminating method. A halogen tungsten lamp is adopted as a light source of a traditional fog lamp, and the light source is high in temperature, short in service life and poor in lighting effect. The automobile LED front fog lens comprises a lens body (1) which is provided with a luminous surface (2). A sand blasting region (3) is arranged on the edge of the luminous surface (2). The chromatic dispersion eliminating method includes the steps of finding the region which is prone to chromatic dispersion on the lens through simulation analysis, utilizing the sand blasting technology or the etching technology to destroy the surface roughness of the region which is prone to chromatic dispersion on the lens to form the sand blasting region, enabling light rays incident on the sand blasting region to carry out diffuse reflection so that part of light rays which will generate chromatic dispersion can be filtered out. Consequently, the chromatic dispersion effect generating nearby a light and shade cut-off line can be weakened and eliminated. The chromatic dispersion eliminating method is applied to the automobile LED front fog lens.
Description
technical field:
the present invention relates to a kind of method of eliminating the front mist lens of LED automobile of dispersion and eliminating dispersion.
background technology:
according to GB4785 regulation, the photochromic requirement of front fog lamp of automobile is white or yellow, and light belt is photochromic will be consistent as far as possible, to avoid driver to produce vision spinning sensation.
tradition fog lamp adopts halogen tungsten lamp as light source, and this light-source temperature is high, and the life-span is low, and light efficiency is poor.LED light source can improve this kind of situation greatly, can be with low operating temperature, and high light efficiency, continuous firing 10000 hours.
adopt non-spherical lens when take the front fog lamp luminous intensity distribution that LED is light source, because rims of the lens refractive index is larger, easily near "cut-off"line, occur obvious dispersion, affect visual effect.
summary of the invention:
the object of the present invention is to provide mist lens before a kind of LED automobile of eliminating dispersion, be particularly related to LED front fog lamp with bracelet face luminous intensity distribution a kind of solution that alleviates and eliminate near dispersion phenomenon "cut-off"line is provided.
the object of the present invention is achieved like this:
the front mist lens of LED automobile of eliminating dispersion, its composition comprises: lens body, on described lens body, there is light-emitting area, at the edge of described light-emitting area, there is sandblast region.
mist lens before the LED automobile of described elimination dispersion, described lens body is processed by glass or PMMA optical material.
mist lens and eliminate the method for dispersion before the LED automobile of described elimination dispersion, first find out the lens position of easy generation dispersion by simulation analysis; Then adopt sandblast or etching technique, destroy this region lens surface roughness, form sandblast region, make to incide the light generation diffuse reflection in sandblast region, filter out the part light that meeting produces dispersion, thereby weaken and eliminate near the chromatic dispersion effects of the generation of "cut-off"line.
beneficial effect:
1. the present invention only carries out blasting treatment to producing the specific region of dispersion, when eliminating dispersion phenomenon, has guaranteed the clear of "cut-off"line.
2. the present invention is simple in structure, and manufacturing process is easy, greatly reduces exploitation and production cost.
accompanying drawing explanation:
accompanying drawing 1 is the front mist lens arrangement schematic diagram of LED automobile of eliminating dispersion.
the specific embodiment:
embodiment 1:
the front mist lens of LED automobile of eliminating dispersion, its composition comprises: lens body 1, on described lens body, there is light-emitting area 2, at the edge of described light-emitting area, there is sandblast region 3.
embodiment 2:
according to mist lens before the LED automobile of the elimination dispersion described in embodiment 1, described lens body is processed by glass or PMMA optical material.
embodiment 3:
according to the method for mist lens before the LED automobile of the elimination dispersion described in embodiment 1 or 2 and elimination dispersion, first by simulation analysis, find out the lens position of easy generation dispersion; Then adopt sandblast or etching technique, destroy this region lens surface roughness, form sandblast region, make to incide the light generation diffuse reflection in sandblast region, filter out the part light that meeting produces dispersion, thereby weaken and eliminate near the chromatic dispersion effects of the generation of "cut-off"line.
Claims (3)
1. the front mist lens of LED automobile of eliminating dispersion, its composition comprises: lens body, is characterized in that: on described lens body, have light-emitting area, at the edge of described light-emitting area, have sandblast region.
2. mist lens before the LED automobile of elimination dispersion according to claim 1, is characterized in that: described lens body is processed by glass or PMMA optical material.
3. the method for mist lens and elimination dispersion before the LED automobile of elimination dispersion according to claim 1 and 2, is characterized in that: the lens position of first finding out easy generation dispersion by simulation analysis; Then adopt sandblast or etching technique, destroy this region lens surface roughness, form sandblast region, make to incide the light generation diffuse reflection in sandblast region, filter out the part light that meeting produces dispersion, thereby weaken and eliminate near the chromatic dispersion effects of the generation of "cut-off"line.
