Background technique
The headlight for vehicles of the prior art mainly has halogen lamp, xenon lamp and LED light, and halogen lamp and xenon lamp will improve brightness
Power must be just improved, and the calorific value for improving lamp body after power will increase, high temperature use big lamp assembly can not for a long time, institute
It to be controlled between 55 ~ 60w with the power of halogen lamp, and the power control of xenon lamp is in 35 ~ 45w or less.
And LED light is to guarantee heat dissipation performance, uses passive and active air cooling heat-removal modalities in the prior art, it is passive to dissipate
The maximum power of heat generally only reaches 20 ~ 24w, and { wick is away from (the distance between two back-to-back lamp bead light-emitting surfaces) in 4 ~ 5mm
When, and use the maximum power of air-cooled LED light that can only accomplish 20 ~ 30w(in wick away from 2 ~ 3mm).Therefore LED light without
The main reason for method raising power is that wick temperature is excessively high, and heat dissipation, which dissipates, not to be come out, and LED lamp is caused to damage, rather than halogen lamp
It is excessively high with the lamp body heating temperature of xenon lamp, its unbearable heat of lamp assembly material is caused, as long as so LED light solves heat dissipation
Problem, so that it may improve performance number 65w or so.
Can all have a hot light decay with the raising of temperature using the LED light of passive and active heat-removal modalities, generally all 10 ~
Between 40%, and liquid cooling mode is to solve the best way of the hot light decay of LED light,
In addition, passively the radiator structure of heat dissipation and active air cooling heat dissipation is excessive used by existing LED, it is big to be placed on again
In lamp assembly, cause installation difficulty high, many vehicles can not be installed, and suitable dress property is influenced.
Utility model content
The purpose of the utility model is to provide a kind of automobile LED headlights, can effectively solve the problems in background technique.
Realizing the technical solution of above-mentioned purpose is: a kind of automobile LED headlight, including the lamp body being installed in lampshade, lamp body
Including lamp holder and LED luminescence component, it is characterised in that: the front end of lamp holder is connected with U-shaped cooling tube, the both ends point of U-shaped cooling tube
Lamp holder is not backed through, and LED luminescence component is mounted in the opening for the U-shaped cooling tube for forward extending out lamp holder.
Further, the LED luminescence component includes circuit board and the LED lamp for being mounted on circuit board two sides.
Further, it is connected and fixed between circuit board and U-shaped cooling tube by welding procedure, one end of the circuit board is in
Arc is simultaneously fitted in the arc end of U-shaped cooling tube, and the arc end of circuit board and the upper and lower end face of two sides and U-shaped cool down
Section fillet weld triangular in shape is respectively formed between pipe.
Further, circuit board is single layer copper sheet, and with a thickness of 0.3 ~ 1mm, LED lamp is welded on the front and back sides of circuit board
On.
Further, the U-shaped cooling tube for forward extending out lamp holder is coated with decorative panel, and LED lamp is to exposing outside dress
Plaque.
Further, the LED headlight further includes the cooling system separately positioned with lamp body, and the cooling system includes water
Row, the water row are provided with inlet and liquid outlet, and the inlet and liquid outlet of water row concatenates U-shaped cooling tube by water pump.
Further, radiator fan is also equipped on the water row.
The utility model has the beneficial effects that
When the utility model is used, start water pump, coolant liquid is delivered in U-shaped cooling tube, is sent out LED by coolant liquid
The heat of optical assembly takes big lamp assembly out of, realizes the high efficiency and heat radiation of LED luminescence component.
The utility model uses the coolant liquid type of cooling, and coolant liquid flows around wick, and wick temperature would not be very high,
Power can increase, and the temperature around the circuit board of the automobile LED headlight of 65w at work is 40 ° or so, can be by hot light
Control decline within 5%, improves the durability of LED headlight；And the automobile LED headlight of existing 20w, 30w circuit at work
Temperature around plate is 110 ° or so, and hot light decay is serious, and product quality is not high.
Because of the blocked up condenser performance that will affect LED luminescence component of circuit board, the circuit board of the utility model is used
Single layer copper sheet, with a thickness of 0.3 ~ 1mm.
Because circuit board is excessively thin, heating conduction will affect, influence to radiate, therefore the circuit board of the utility model and U-shaped are cold
But be connected and fixed between pipe by welding procedure, the upper and lower end face and U-shaped cooling tube of the arc end of circuit board and two sides it
Between be respectively formed section fillet weld triangular in shape, the fillet weld of triangle can effectively improve circuit board and U-shaped cooling tube it
Between contact area, and the relative increase thickness of circuit board improves heat dissipation performance.
The utility model is separately positioned with lamp body by cooling system, reduces the size of lamp body, and the size with halogen lamp connects
Closely, it is wider to fit entrucking type range.
The utility model is also equipped with radiator fan on water row, is realized by radiator fan to the coolant liquid in water row
It is quickly cooled down.
