Description

A kind of LED light source headlamp
Technical field
The utility model relates to automotive lighting technical field, be specifically related to a kind of LED light source headlamp.
Background technology
Car headlamp is one of vitals ensureing automotive safety operation.In recent years, progress along with lighting source technology, car headlamp experienced one from incandescent lamp to Halogen lamp LED again to the evolution of HID lamp, yet, these conventional light source all belong to the glass bulb light fixture of vacuum or inflation, in various aspects such as brightness, life-span, volume, heating degree, colour temperature adjustment and robustnesses, all exist fatal weakness.The application of LED technology on automobile is increasingly extensive, now by tail-light, is marched the category of headlight.Compare with traditional incandescent lamp, the headlight that LED makes not only illuminating effect is high, and energy resource consumption is low.In equal illumination situation, it is a greater part of of halogen regenerative-cycle headlamp that High Power LED is worked as the demand of electric weight.Outside joint source, the advantage that is difficult to match in excellence or beauty that LED also possesses a lot of other materials is such as its life-span reaches 10000 hours, basic suitable with the normal service life of a car.Another feature of LED lamp is exactly that irradiation area has range.
Also there are some defects in the LED light source for car headlamp at present, and speculum can not be gone out light reflection well, gives the use of automobile with certain unsafe factor.
Utility model content
For the deficiency existing in prior art, the utility model object is to be to provide a kind of LED light source headlamp, have advantages of that the life-span is long, energy-conservation, light quality is good, simple in structure, response fast, voltage is low, volume is little, and reflecting effect is good, practical.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of LED light source headlamp, comprise aluminum heat-dissipating casing, pcb board, LED light source, the first reflector, the second reflector, the first baffle plate and second baffle, aluminum heat-dissipating casing bottom is provided with pcb board, on pcb board, be provided with LED light source, under LED light source, front side is provided with the first reflector, LED light source upper right side is provided with the second reflector, between LED light source and the second reflector, be provided with the first baffle plate, the first baffle plate front side and the first reflector top are provided with second baffle.
According to above-mentioned a kind of LED light source headlamp, wherein, the first described reflector is ellipsoidal reflector.
According to above-mentioned a kind of LED light source headlamp, wherein, the second described reflector 5 is parabolic reflector.
The utlity model has the advantage that the life-span is long, energy-conservation, light quality is good, simple in structure, response fast, voltage is low, volume is little, and reflecting effect is good, practical.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: a kind of LED light source headlamp, comprise aluminum heat-dissipating casing 1, pcb board 2, LED light source 3, the first reflector 4, the second reflector 5, the first baffle plate 6 and second baffle 7, aluminum heat-dissipating casing 1 bottom is provided with pcb board 2, on pcb board 2, be provided with LED light source 3, 3 times front sides of LED light source are provided with the first reflector 4, LED light source 3 upper right sides are provided with the second reflector 5, between LED light source 3 and the second reflector 5, be provided with the first baffle plate 6, the first baffle plate 6 front sides and the first reflector 4 tops are provided with second baffle 7.
It should be noted that the first described reflector 4 is ellipsoidal reflector.
In addition, the second described reflector 5 is parabolic reflector.
This specific embodiment is by realizing the luminous intensity distribution needing with the light that speculum reflection source (White LED) sends.The LED headlamp of this specific embodiment is used primary event mirror (elliptical reflector), lampshade, these three reflectings surface of secondary reflection mirror (parabolic mirror) to carry out luminous intensity distribution, primary event mirror is provided near the vertical direction of White LED, and the light path of light changed course that White LED is sent is projected to secondary reflection minute surface.Baffle plate has the function (blocking function) that beam shape that headlamp is sent is adjusted.Secondary reflection mirror can reflect light that primary event mirror and lampshade reflect back and part directly from the light of White LED, and finally the light as headlamp radiates away.At this moment, the light of White LED is to be undertaken after 1~3 secondary reflection by these reflectings surface, to headlamp outside, penetrates.In reflecting surface, the shape of secondary reflection mirror is the most complicated.A plurality of reflectings surface, consisting of, is not throw light merely, but can be to necessary position allotment light.
This specific embodiment has advantages of that the life-span is long, energy-conservation, light quality is good, simple in structure, response fast, voltage is low, volume is little, and reflecting effect is good, practical.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
