Description

A kind of LED specular removals headlamp tool
Technical field
The utility model is related to a kind of Vehicular lamps, have more particularly, to a kind of LED specular removals headlamp.
Background technology
The big lamp type of several moneys of preceding mainstream on the market, there is halogen regenerative-cycle headlamp, xenon headlight and LED headlights respectively.Halogen is big The shortcomings that lamp is maximum is luminance shortage, and road lighting effect is not as good as xenon headlight and LED headlights, and service life is also relatively It is short.Present requirement of the people to light source is gradually increased, and halogen regenerative-cycle headlamp can be gradually substituted.Xenon headlight is relative to halogen regenerative-cycle headlamp section Skill degree higher, but cost is higher, high cost, and it is also relatively slow to start speed.The trend developed at present is to use LED headlights, LED headlights belong to emerging energy, and cost is very low, but required technology is very high.2008, Audi used on A4 first LED side-marker lamps, have first turned on the LED headlight epoch.Many manufacturers all start to follow up later, all start using LED side-marker lamps, Europe even starts law-making stipulation now, and for driving safety, all vehicles on sale must all assemble LED side-marker lamps.It excellent Gesture:It generates heat small, more efficient, longer life expectancy, and also plasticity is very strong, can design a variety of different moulding.
Mainstream LED headlights, H4, H7 as disclosed in Chinese patent CN105423217A are mounting groove knot on the market at present Structure is equipped with vertical heat-radiating rod that is, on lamp holder, sets two rectangle mounting grooves in the plane of symmetry of heat-radiating rod to place LED patches. But due to heat dissipation, LED patches can only put several per face, and be about 120 degree per the light emitting angle of LED patch, be produced Raw beam angle has the effect of scattering halation, causes illumination light efficiency uneven, makes one to generate dazzling, influence traffic safety.
Chinese patent CN10544081A discloses a kind of secondary reflection light distribution LED automobile lamp, including car light main body and glass Cover, the glass cover are installed in the car light main body, form space in closed lamp;The car light main body is by car light shell Body, LED light source, heat carrier and primary event face are formed;The lamp body for heat dissipation light distribution integrated shell, the car light shell The inner surface of body is secondary reflection face, and the secondary reflection face is the parabolic surface of evagination;The heat carrier is perpendicular to described Glass cover is set, and is equipped at least one LED light source and close to the primary event face of the LED light source;The LED light source Light-emitting surface center is set in the parabolic surface focus in the secondary reflection face, the primary event face and the LED light source Light-emitting surface surface is vertical, but the shape and size of the primary event body in the patent are specific based on secondary reflection face therein Shape designs, and the light-source system in this patent and signal light are fixed, can not accomplish polynary matching.
Utility model content
The purpose of this utility model is exactly to provide a kind of LED specular removals to overcome the problems of the above-mentioned prior art Headlamp has.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of LED specular removals headlamp tool, including:
Radiator is provided with lamp panel on the outside of radiator, can lamps and lanterns be rapidly secured at lamp body by lamp panel On,
The LED light source on radiator top is arranged on,
The primary event body being arranged at the top of LED light source, by LED light source generate light beam rearrangement into 360 degree entirely dissipate by Light is controlled, is refracted on vehicle lamp body, can realize comprehensive illumination in this way, illumination blind area will not be formed.
As preferred embodiment, the primary event body is conical reflector, and such primary event body is set Uncurrent defect is avoided on meter, as long as can install 2 secondary reflection bodies of halogen bulb can be compatible with this light source.
As more preferred embodiment, the apex angle of the conical reflector is 100 ° -150 °, avoids LED The characteristic of light source angle, after primary event body, light shafts become 360 degree of refractions.
As best embodiment, light-source angle, conical reflector are devised according to the technical standard of halogen bulb Apex angle be 120 ° or 123 °
As preferred embodiment, LED light source is connect with primary event body by glass-tube, in this way by adjusting glass-tube, The distance between LED light source and reflector can be adjusted, due to various headlight various types currently on the market, wherein mainstream There are H1, H2, H3, H4, H7 etc..These are all the models of halogen regenerative-cycle headlamp bubble.The lamp housing shape of each car manufacturer's exploitation, instead Irradiating light beam requirement is different, and in order to more be compatible with each producer's lamp housing size, Pass through above-mentioned technical proposal realizes adjustment distance, from It and can be in different applications.
As preferred embodiment, the LED light source is the LED light source with lens being arranged in array, and is used LED light source is changed to the LED light source with lens on direct radiator top surface, is cancelled and dissipated by traditional cylindricality mounting groove paster structure Hot pin and radiator fan.
Compared with prior art, the utility model has the following advantages:
1st, by traditional cylindricality mounting groove paster structure, it is changed to paster structure on direct radiator top surface.LED light after improvement Source is placed directly against on radiator, can play cooling effect well, so traditional cylindricality heat-radiating rod and radiator fan are eliminated, It is energy saving and improve efficiency.
2nd, traditional LED patches are changed to the LED light source with lens, and lens have the effect of aggregation light source, eliminate by LED light Diverging light caused by source, makes luminous energy all be refracted on reflecting surface, efficiently uses light source, improves light efficiency.In addition, due to list The luminous flux of a LED is small.Single led luminous flux research level is up to 120lm/W at present, Product Level≤60lm/W, and High-power LED will often increase the very big radiator of size, so the LED light source that we design uses LED array design side Method.
3rd, by directly turning to be shot out after traditional light source direct projection to lamp housing, light source is changed to by lens, it is anti-to be first mapped to taper It gathers together, then is refracted on lamp housing on beam, finally turn to be shot out, solve beam angle caused by LED light source and cause Light efficiency it is uneven the phenomenon that.Light source is efficiently used, light decay is few, and light efficiency improves, no beam angle, shadow-free, increases safety coefficient.
