Technical field
The present invention relates to a kind of high efficiency automotive LED Fog-proof light, belong to automobile anti-fog lamp technical field.
Background technology
At present, automobile anti-fog lamp of the prior art generally adopts incandescent lamp or halogen lamp as light source, this employing incandescent lamp or halogen lamp not only also exist the high problem of energy consumption as the automobile anti-fog lamp of light source, but also it is more weak to there is penetration power, easy damage, the problem that service life is shorter, for addressing this problem, propose the technical scheme adopting LED diode as Fog-proof light light source in the prior art, application number disclosed in Chinese patent literature is " 200910107635.0 ", the light source adopting LED diode as Fog-proof light is just proposed in the technical scheme that denomination of invention is " LED automobile Fog-proof light ", although the energy consumption solving conventional light source in this technical scheme is high, service life is short, the problem that Fog-proof light penetration capacity is weak, but in this technical scheme, in order to reduce the operating temperature of LED diode, have employed and radiator is close in the rear end of LED, and utilize the circulation of radiator water to reduce the operating temperature of LED diode with delivery port by the method that water pipe is communicated with radiator the water inlet on the cavity of radiator.The technical scheme that in existing this employing radiator, water circulation carrys out cooling LED diode temperature not only also exists installs complicated problem, and by needing when mounted to be connected with the water tank of automobile, the water circulation structure of water tank must be changed, therefore can have a certain impact to the performance of automobile; In addition, what this technical scheme adopted is that cooling water car cools, and automobile operationally, and its water temperature is general all at about 85 DEG C, and LED diode will premature aging when 75 DEG C of work.Therefore its cooling effect is unsatisfactory, thus can not give full play to the luminous efficiency of LED diode.Therefore, the result of use of existing automobile anti-fog lamp or not ideal enough.
Summary of the invention
The object of the invention is: provide a kind of energy-conservation, operating efficiency is high, result of use good and high efficiency automotive LED Fog-proof light that is easy for installation, that need not change automobile original structure, to overcome the deficiencies in the prior art.
The present invention is achieved in that a kind of high efficiency automotive LED Fog-proof light of the present invention, comprise lamp box, in lamp box, LED circuit board is installed, LED circuit board is provided with LED light emitting diode, the semiconductor refrigerating plate be made up of semiconductor cold reactor galvanic couple element is provided with at the back side of LED circuit board, the back side of LED circuit board is close in the cold junction face of semiconductor refrigerating plate, the face, hot junction of semiconductor refrigerating plate is provided with heat-conducting plate, heat-conducting plate is provided with rear portion fin, and on heat-conducting plate, be plugged with heat pipe, heat pipe is fixed with top heat dissipation sheet, top heat dissipation sheet is arranged on the top of lamp box, in lamp box, the front of LED light emitting diode is provided with reflector, is provided with convex lens in the front end of reflector.
In above-mentioned high efficiency automotive LED Fog-proof light, lamp box is provided with the power supply galvanostat that can be connected with automobile power source, and LED circuit board is connected with power supply galvanostat by wire with semiconductor refrigerating plate.
In above-mentioned heat-conducting plate, be provided with cavity, and the interior tube chamber of heat pipe is connected with the cavity of heat-conducting plate, in the cavity of heat-conducting plate, heat-conducting liquid is housed.
Above-mentioned heat-conducting liquid is water, distilled water, alcohol or acetone.
Above-mentioned lamp box is provided with mounting bracket.
Above-mentioned LED light emitting diode is the LED light emitting diode of jaundice color light source.
Above-mentioned convex lens are the convex lens of water white transparency or yellow transparent.
Owing to have employed technique scheme, the present invention adopts semiconductor refrigerating plate directly to carry out thermo-neutrality electronic temperature-decreasing to LED circuit board, and on the face, hot junction of semiconductor refrigerating plate, heat-conducting plate is installed, heat-conducting plate arranges rear portion fin and at the top of lamp box, top heat dissipation sheet is installed, be connected with top heat dissipation sheet by the heat pipe of grafting on heat-conducting plate.Like this when LED LED operation in LED circuit board, the cold junction of its semiconductor refrigerating plate directly carries out thermo-neutrality to LED circuit board, and semiconductor refrigerating plate is when cooling, the heat that its hot junction produces is dispersed in air by rear portion fin and top heat dissipation sheet, and when heat-conducting plate heat conduction, heat-conducting liquid in heat-conducting plate cavity is because being evaporated by heating, be cooled after its steam arrives rapidly top heat dissipation sheet place by heat pipe and become liquid form, flow back into again in the cavity of heat-conducting plate, circulation like this, thermo-neutrality can be carried out efficiently to LED circuit board and LED light emitting diode.After tested, high efficiency automotive LED Fog-proof light of the present invention operationally, the operating temperature of its LED circuit board and LED light emitting diode is general below 30 DEG C after thermo-neutrality, and the brightness of list LEDs 5W to 25W power of the present invention is equivalent to the brightness commonly using now Fog-proof light 150W to 750W power; And the penetration power of the light of Fog-proof light of the present invention is the penetration power more than tens times of existing Fog-proof light.Therefore the present invention is adopted effectively can to improve the security of travelling in fog day.So, the present invention compared with prior art, the advantage that the present invention not only has good energy-conserving effect, operating efficiency is high, brightness is high, penetration power is strong, but also have easy for installation, automobile original structure need not be changed, the advantages such as automobile originality energy can not be affected when installing, and the security performance adopting the present invention significantly can improve automobile to travel in the large greasy weather.
