Abstract
The utility model relates to a car LED headlight with high radiating efficiency, which comprises a shell, a light distributor, a reflector, LED light sources and a radiating device. The radiating device includes a heat conducting post, a heat conducting copper tube, a fin unit and an extractor fan, the middle of the cylindrical heat conducting post is fixedly connected with the shell, one end of the heat conducting post extends into the reflector, and the other end of the heat conducting post extends out of the shell. The LED light sources including an upper light source and a lower light source are respectively fixed on the upper portion and the lower portion of one end of the heat conducting post extending into the reflector. The U-shaped heat conducting copper tube with an opening facing the LED light sources is embedded in the heat conducting post. The fin unit is wrapped outside one end of the heat conducting post extending out of the shell, and the extractor fan is arranged on the end surface of one end of the heat conducting post extending out of the shell. The car LED headlight is novel in design, reasonable in structure, high-efficiency in radiating of the LED light sources and has excellent popularizing value and market prospect.
Description
Technical field
The utility model relates to a kind of car headlamp, especially a kind of LED car headlamp of high efficiency and heat radiation.
Background technology
Car headlamp is one of vitals that ensures the automotive safety operation.In recent years, along with the lighting source development of technology, car headlamp experienced one from the incandescent lamp to the Halogen lamp LED again to the evolution of HID lamp, these conventional light source all belong to the glass bulb light fixture of vacuum or inflation, all exist fatal weakness in various aspects such as brightness, life-span, volume, heating degree, colour temperature adjustment and robustnesses.The LED car headlamp is exactly a kind of headlamp of configuration led light source, compares with traditional car headlamp, have the life-span long, energy-conservation, light quality is good, simple in structure, response soon, advantage such as voltage is low, volume is little, become and fallen over each other hot of research and development both at home and abroad.
Yet, have the low problem of car headlamp ubiquity radiating efficiency of using led light source now, directly aggravate the light decay of led light source, cause not only existing the potential safety hazard of driving, and shorten the service life of led light source.
Thereby the heat dissipation technology of existing LED car headlamp awaits to improve and improve.
Summary of the invention
At the deficiencies in the prior art part, the purpose of this utility model provides a kind of LED car headlamp of high efficiency and heat radiation.
For achieving the above object, technical solution adopted in the utility model is: a kind of LED car headlamp of high efficiency and heat radiation, comprise shell, lens, speculum, led light source and heat abstractor, heat abstractor is made up of heating column, heat-conducting copper pipe, fins group and extractor fan, fixedly connected with shell in the middle part of cylindrical heating column, one end stretches in the speculum, and the other end stretches out outside the shell; Two were separately fixed at the position up and down that heating column stretches into an end in the speculum about led light source divided; Heating column inside is embedded with the U-shaped heat-conducting copper pipe of opening towards led light source; The outer surface coating that heating column stretches out shell one end is provided with fins group; The end face that heating column stretches out shell one end is provided with extractor fan.
The beneficial effects of the utility model are: owing to adopt said structure, the heat that led light source produced can be transferred to outside the shell by heating column and heat-conducting copper pipe rapidly, further dispel the heat by fins group and extractor fan again, thereby improve the radiating efficiency of LED car headlamp, effectively alleviate the light decay of led light source, not only improve the safety guarantee of driving, and prolong the service life of led light source.The utility model modern design, rational in infrastructure, possess the characteristics of led light source high efficiency and heat radiation, have excellent generalization values and market prospects.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, also is that specification digest is with scheming.Each label is respectively among the figure: (1) shell, (2) lens, (3) speculum, (4) led light source, (5) heat abstractor, (6) heating column, (7) heat-conducting copper pipe, (8) fins group, (9) extractor fan.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to accompanying drawing, the LED car headlamp of a kind of high efficiency and heat radiation of the utility model, comprise shell 1, lens 2, speculum 3, led light source 4 and heat abstractor 5, heat abstractor 5 is made up of heating column 6, heat-conducting copper pipe 7, fins group 8 and extractor fan 9, fixedly connected with shell 1 in the middle part of cylindrical heating column 6, one end stretches in the speculum 3, and the other end stretches out outside the shell 1; Led light source 3 minutes up and down two be separately fixed at the position up and down that heating column 6 stretches into ends in the speculum 3; Heating column 6 inside are embedded with the U-shaped heat-conducting copper pipe 7 of opening towards led light source 4; The outer surface coating that heating column 6 stretches out shell 1 one ends is provided with fins group 8; The end face that heating column 6 stretches out shell 1 one ends is provided with extractor fan 9.
The above, it only is a kind of preferred embodiment of the utility model, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of the utility model technology any trickle modification, equivalent variations and modification that top embodiment did.
