Description
Technical field
The invention belongs to LED technology field, more particularly to a kind of water-cooling type automobile-used LED headlight that can eliminate glare.
Background technology
LED is the abbreviation of English light emitting diode (light emitting diode), and its basic structure is one piece of electroluminescent
Chip of semiconductor material, with elargol or latex solidified to support, then connect chip and circuit board with silver wire or gold thread,
Then surrounding is sealed with epoxy resin, is played a part of protecting internal core, is finally installed shell.With advantages below：
1st, save：The energy consumption of white light LEDs is only the 1/10 of incandescent lamp, and the 1/4 of electricity-saving lamp；Using super bright high-power LED
Light source, coordinate high-efficiency power, than conventional incandescent economize on electricity more than 80%, brightness is 10 times of incandescent lamp under equal-wattage；
2nd, it is long-lived：Life-span is more than 50 times of traditional tengsten lamp up to more than 50000 hours, can to average family illumination
Call " putting things right once and for all "；
3rd, impact resistance, anti-Lei Liqiang, no ultraviolet (UV) and infrared ray (IR) radiation, no filament and glass shell,
There is no traditional tube fragmentation problem, to human body fanout free region；
4th, solid encapsulation, cold light Source Type is belonged to, it can transport and install very well, can be installed in any miniature and envelope
In the equipment closed, vibration is not afraid of；
5th, it is environmentally friendly, the pollution element such as not leaded, mercury, there is no any pollution to environment, and the assembling parts of LED bulb are non-
Chang Rongyi is dismounted, and can be reclaimed without producer's recovery by other people.
6th, without stroboscopic, pure DC operation, visual fatigue caused by conventional light source stroboscopic is eliminated；
7th, wide-voltage range, global general-use LED is in 85V~264VAC full voltage range constant currents, guarantee life-span and brightness
Do not influenceed by voltage pulsation；
8th, light and may be up to 80lm/w depending on dumping ratio, have a variety of LED colour temperatures optional, colour rendering index is high, and colour rendering is good.
Because the more traditional incandescent lamp of LED has above advantage, in recent years, using LED as the automobile of light source before
Headlight application is gradually extensive, also there is extraordinary application prospect.However, the heat dissipation problem one of great power LED headlight
It is directly the bottleneck that its further genralrlization uses, water cooling radiating type LED headlamp emerging at present has good radiating effect,
But the water-cooling structure of traditional water-cooling type LED headlights is typically more complicated, cost is also higher.In addition, existing automobile-used LED
Headlight there is problems：(1) pollutants such as dust are easily accessible in headlight lampshade, cleaning is very difficult；(2)
Long-term use, pollutant gradually accumulate the illuminating effect that can directly affect car light；(3) can only observe by the naked eye in lampshade
Pollution condition, intellectualized detection means can not be utilized accurately to detect the information such as the smokescope in lampshade；(4) dedusting structure is multiple
It is miscellaneous, in-convenience in use and cost height；(5) non-uniform light, glare is easily produced, the eyes of people feel under the weather, when long
Between using it is also possible to affecting one's power of vision.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide the cooling water pair that a kind of water spray tank using automobile is drawn
LED headlamp is cooled down rapidly, and cost is low and cooling velocity is fast；Expand in the flash ranging that goes out of LED provided with light guide plate and light
Fall apart, effectively eliminate the water-cooling type automobile-used LED headlight that can eliminate glare of glare.
The purpose of the present invention is achieved through the following technical solutions：Before a kind of water-cooling type automobile-used LED that can eliminate glare
Headlight, including lamp body and water cooling plant, the lamp body include lampshade, annular aluminium base and are arranged at more on annular aluminium base
Individual LED, the light emission side of LED light are disposed with light guide plate and light diffusing sheet, and light guide plate and light diffusing sheet are installed successively
In lampshade；The water cooling plant includes metal cooling board and water spray tank；Annular aluminium base is closely connected with metal cooling board,
Water storage cavity is provided with metal cooling board, the exit and entrance of water storage cavity is connected with the water spray tank of automobile respectively；Described lamp body is also
Including smoke inductor and dust extraction fan, smoke inductor is arranged in lamp, and dust extraction fan is arranged at what annular aluminium base was formed
The bottom of cooling chamber.
Further, the position being engaged on described lampshade with dust extraction fan is provided with dedusting opening.
Further, the light guide plate uses the PMMA sheet materials of optical grade, and light guide plate surface is printed on thin with screen printing techniques
Reflective spot close, not of uniform size；Light diffusing sheet is using light diffusion PC or PMMA materials.
The beneficial effects of the invention are as follows：
1st, the cooling water drawn using the water spray tank of automobile is cooled down rapidly to LED headlamp, and simple in construction, cost is low
And cooling velocity is fast；
2nd, go out flash ranging provided with light guide plate and light diffusing sheet in LED so that the light that LED is sent evenly, effectively
Glare is eliminated, reduces injury of the light to human eye；
3rd, the pollution condition in lampshade is detected intelligently, exactly using smoke inductor, when detecting seriously polluted in lampshade,
Automatically turn on dust extraction fan and corresponding dedusting opening and dedusting is carried out to headlight, it is easy to use, can persistently it ensure big before LED
The good illuminating effect of lamp；For being observed compared with conventional macroscopic, improved using the intelligent acquisition mode of smoke inductor in lampshade
The accuracy and reliability of smokescope detection.
