Description
Technical field
The present invention relates to a kind of Vehicular lamps, have more particularly, to a kind of automobile-used LED high photosynthetic efficiency headlamp.
Background technique
The big lamp type of several moneys of preceding mainstream on the market, there is halogen regenerative-cycle headlamp, xenon headlight and LED headlight respectively.Halogen is big
Lamp is maximum the disadvantage is that luminance shortage, and road lighting effect is not as good as xenon headlight and LED headlight, 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 Du Genggao, but higher cost, expense is high, and starting speed is also relatively slow.The trend developed at present is to use LED headlight,
LED headlight belongs to emerging energy, and cost is very low, but required technology is very high.2008, Audi used on A4 first
LED side-marker lamp, has first turned on the LED headlight epoch.Many manufacturers all start to follow up later, all start using LED side-marker lamp,
Europe even starts law-making stipulation now, and for driving safety, all vehicles on sale must all assemble LED side-marker lamp.It excellent
Gesture: small, more efficient, longer life expectancy of generating heat, and also plasticity is very strong, can design a variety of different moulding.
Mainstream LED headlight, 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 patch.
But due to radiating, the every face of LED patch can only put several, and the light emitting angle of every LED patch is about 120 degree, is 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, constitute 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 constituted；The lamp body is 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
The setting of glass cover is equipped at least one LED light source and the primary event face close to 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 design, and the light-source system in this patent and signal light be it is fixed, can not accomplish polynary matching.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of automobile-used LED high photosynthetic efficiencies
Headlamp tool.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of automobile-used LED high photosynthetic efficiency headlamp tool, comprising:
Radiator is provided with lamp panel on the outside of radiator, lamps and lanterns can be rapidly secured at lamp body by lamp panel
On,
The LED light source on radiator top is set,
Primary event body at the top of LED light source is set, by LED light source generate light beam rearrangement at 360 degree entirely dissipate by
Light is controlled, is refracted on vehicle lamp body, can be realized comprehensive illumination in this way, not will form illumination blind area.
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 optimal 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, in order to more be compatible with each producer's lamp housing size, realizes adjustment distance through the above technical solution, from
And it 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 by traditional cylindricality mounting groove paster structure, cancels and dissipating
Hot pin and radiator fan.
Compared with prior art, the invention has the following advantages that
1, 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 heat spreading function well, so traditional cylindricality heat-radiating rod and radiator fan are eliminated,
Energy conservation and improve efficiency.
2, traditional LED patch is 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, is refracted to luminous energy all 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.
3, 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 unevenness phenomenon.Light source is efficiently used, light decay is few, and light efficiency improves, no beam angle, shadow-free, increases safety coefficient.
