Abstract
The invention discloses a kind of automobile LED headlights that illumination good brightness heat dissipation performance is strong, it is related to automobile lamp technical field, and major part includes buckle, buckle washer, heat radiator body, LED substrate, plastic cement light source cover, light source cover upper cover, screw, light source cover lower cover, LED connecting plate, fan fixed screw, radiator fan and rear cover.Core the most is plastic cement light source cover in above-mentioned part, the plastics light source cover of orthodox car LED headlight is all directly to smear fluorescent powder on the surface of light source cover to increase the brightness of illumination, but it is directly not quite similar in the thickness that the shortcomings that surface smearing fluorescent powder is fluorescent powder, cause translucent effect different, the light unshapeliness irradiated, and plastic cement light source cover of the invention is equally added with fluorescent powder, but fluorescent powder can be mixed before light source cover forms together with raw material, achieve the purpose that evenly dispersed, plastics light source cover after molding more effectively improves illumination brightness, and it is used for a long time, defect after will not being scratched the fluorescent powder on light source cover surface as film.
Description
Technical field
The present invention is a kind of automobile LED headlight that illumination good brightness heat dissipation performance is strong, and in particular to automobile lamp technology neck
Domain.
Background technique
The automobile LED headlight illuminace component important as automobile, traditionally the plastics light source cover in automobile LED headlight is all
It is to change brightness and the color of illumination by smearing fluorescent powder on surface to reach ideal effect, but smear fluorescence on surface
Powder is substantially all that the fluorescent powder thickness that will cause on light source cover surface is different, and then leads to brightness, effect and the unevenness of tint of light
Claim, and use for a long time is got off, the fluorescent powder on surface can fall off failure.Other part automobile LED headlight heat dissipation performance is poor, long
Time service easily makes internal generation high temperature and causes to burn.
Summary of the invention
In order to solve problem above, the object of the present invention is achieved like this: a kind of illumination good brightness heat dissipation performance is strong
Automobile LED headlight, which is characterized in that including buckle, buckle washer, heat radiator body, LED substrate, plastic cement light source cover, on light source cover
Lid, screw, light source cover lower cover, LED connecting plate, fan fixed screw, radiator fan and rear cover, the radiator fan pass through fan
Fixed screw is installed in the bottom of heat radiator body；The LED connecting plate is located between radiator fan and heat radiator body；The LED
It totally two pieces of substrate, is fitted in the upper vallecular cavity and lower vallecular cavity that heat radiator body is equipped with respectively；It is inserted by vallecular cavity the LED substrate end
Enter in the hole location being equipped with to LED connecting plate, top then passes through rivet and fixes its position in heat radiator body；The screw is successively
The modeling of relative direction is connected and fixed after light source cover upper cover, plastic cement light source cover and heat radiator body equipped with LED substrate
Glue light source cover and light source cover lower cover；The buckle washer is placed into the groove that heat radiator body root is equipped with；The buckle covers
The root of heat radiator body；The rear cover is fixed by screws in the bottom of heat radiator body.
Preferably, it covers after described equipped with heat release hole.
Preferably, the plastics light source cover is mixed with made of the rubber of fluorescent powder.
The invention has the following advantages:
(1) buckle washer is equipped between buckle and radiator, buckle washer plays the role of limit, fixation to buckle, is not easy
It falls off, but is easy to assemble and disassemble.
(2) LED is arranged in LED substrate, and LED substrate is close in the vallecular cavity that heat radiator body is arranged in, and heat can
It is being distributed in heat radiator body at the first time, then taken away by the radiator fan of bottom.
(3) it is equipped with radiator fan in rear cover of the present invention, is obviously improved heat dissipation performance of the invention, effectively prevent zero internal
Part is burnt because temperature is excessively high, can be prolonged the service life.
(4) plastics light source cover is made of the rubber for being mixed with fluorescent powder, and comparison smears fluorescent powder outside plastics light source cover,
Directly addition fluorescent powder stirs molding to the present invention together in process of production, and such fluorescent powder is evenly distributed on cover, effectively
Ground improves illumination brightness, and required fluorescent powder dosage is less in manufacturing process, reduces manufacturing cost to a certain extent.
(5) plastics light source cover can carry out dismounting and change by screw, can renew according to actual needs or colour changing (different fluorescence
The manufactured light source cover color come out of powder is different).
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings and specific examples.
Figure one is explosive view of the invention.
Specific embodiment
In order to make the technical means, creative features, achievement of purpose and effectiveness of the invention easy to understand, below with reference to tool
Invention is further described in body embodiment.
Referring to figure one, present embodiment uses a kind of following technical scheme: vapour that illumination good brightness heat dissipation performance is strong
Vehicle LED headlight, which is characterized in that including buckle 1, buckle washer 2, heat radiator body 3, LED substrate 4, plastic cement light source cover 5, light source
Cover upper cover 6, screw 7, light source cover lower cover 8, LED connecting plate 9, fan fixed screw 10, radiator fan 11 and rear cover 12, it is described to dissipate
Hot-air fan 11 is installed in the bottom of heat radiator body 3 by fan fixed screw 10；The LED connecting plate 9 is located at radiator fan 11
Between heat radiator body 3；It totally two pieces of the LED substrate 4, is fitted in the upper vallecular cavity and lower vallecular cavity that heat radiator body 3 is equipped with respectively；
4 end of LED substrate is inserted into the hole location that LED connecting plate 9 is equipped with by vallecular cavity, and top then passes through rivet and fixes it scattered
Position in hot ontology 3；The screw 7 sequentially passes through light source cover upper cover 6, plastic cement light source cover 5 and the heat dissipation equipped with LED substrate 4
The plastic cement light source cover 5 and light source cover lower cover 8 of relative direction are connected and fixed after ontology 3；The buckle washer 2 is placed into scattered
In the groove that hot 3 root of ontology is equipped with；Root of 1 set of the buckle in heat radiator body 3；The rear cover 12 is fixed by screw 7
