Description
Technical field：
A kind of automobile-used LED headlight, belongs to automobile-used headlight, especially automobile headlight.
Background technology：
The advantages of LED illumination has efficient, energy-conserving and environment-protective, fast response time, in each neck in addition to automobile-used headlight
Domain is widely applied, and is the lighting luminaries of current high-quality.LED rarely has application on automobile-used headlight, be exactly because
There is problems with to need to solve on the problems such as facing illumination range, light shape, dazzle, illumination range：
1st, LED illuminator lighting angle is small compared with common light angle in itself, thus area of illumination exist dark space compared with
Greatly, illumination range is small, and light efficiency is low, influences the illumination of vehicle；
2nd, LED illuminator is used for dipped headlight, and illuminator is excessively concentrated, and its range is too small, about 20 meters or so, is unfavorable for car
Illumination, and illuminator excessively concentrate be unfavorable for radiating；
3rd, due to above reason, if LED illuminator conventionally installed, i.e., illuminator using lens axis in
Heart line is arranged in fulcrum bearing, reflector is combined into one and used using two or two reflectors, then the light shape meeting of LED illuminator
It is very poor, harmful light is easily scattered, dazzle is produced, there is potential safety hazard to the driver or pedestrian gone in the same direction.
Goal of the invention：
The problem to be solved in the present invention is not enough aiming at more than and provides a kind of simple in construction, can effectively solve light irradiation
The problems such as journey, light shape, dazzle, illumination range, oneself car lighting, and the car not impacted to others can be met well
Use LED headlights.Its technical scheme is as follows：
It includes illuminator, fulcrum bearing, reflector, lens and shell, and illuminator is arranged in fulcrum bearing, and lens are located at hair
In front of body of light, radiator and fan are installed on the outside of fulcrum bearing.Its key technology is that illuminator is eccentrically mounted relative to lens axis
In in fulcrum bearing, reflector is arranged in fulcrum bearing close to illuminator, in fulcrum bearing the side relative with illuminator perpendicular to
Lens axis is installed and cuts mating plate.
The emitter surface and flat face where reflective bowl bottom.
The reflector is semicircle reflector.
Compared with prior art, the present invention has the advantages that：
1st, illuminator is eccentrically mounted compared to lens axis in fulcrum bearing, and semicircle reflector is arranged on close to illuminator
In fulcrum bearing, so whole illuminator and reflector are all located at the upper half part of optical axis, so whole emergent light is all pointed into optical axis
Lower portion, i.e., the light that whole illuminator is sent will all be pointed into road surface, and illuminator utilization rate reaches maximization.
2nd, the effect for cutting mating plate is that the edge of light is repaired, and does not produce dazzle, makes the edge more neatly and orderly of light,
Do not influence the driver gone in the same direction.Mating plate is cut against optical axis and lens focus position, positioned at illuminator opposite side, by optical axis
The incident photo-electric switch of lower section, only allow the incident light above optical axis by lens, so that in front of the lens outside the convergent point of light
To one using optical axis as boundary on it is dark under bright semicircle irradiated region.When illuminator is placed in above optical axis, the installation site of mating plate is cut
Difference, the utilization rate to incident light is then entirely different, smaller to the cutting quantity of incident light closer to focus, the utilization to illuminator
Rate is bigger, so, cutting best results when mating plate is placed in lens focus position.
3rd, LED illuminator has certain lighting angle, such as its lighting angle of illuminator used when testing is 115
Degree, reflector is installed by existing mode, and the light that illuminator edge is sent will irradiate reflecting surface root less than reflector, so that
Projection light irradiated region is caused to form dark space, influence illumination in connection place with reflected light irradiated region.Emitter surface of the present invention with it is anti-
Flat face where light bowl bottom so that the light-emitting area of illuminator connects with the reflecting surface base plane of reflector, so reflective
The reflecting surface bottom of bowl is in the range of exposures Inner in light face, and projection light and reflected light connection place are not in just dark space.
In this way, obtaining the large area for the free from glare that a semicircular centre is projection light, periphery is reflected light in lens far ahead
Area of illumination, illumination range is appropriate, beneficial to the driver or pedestrian gone in the same direction.
4th, tested using product of the present invention, curtain wall is away from 10 meters before lamp, and its illumination pattern is obvious for semicircle but tangent line, brightness
Height, photographed object and road surface Qing Xi Ming are bright when real road is illuminated.Light-emitting area area is relatively small when the present invention is as high beam, uses
Make light-emitting area area during dipped headlight relatively large.Middle brighter area of illumination is projection area of illumination, is around reflected light irradiated region,
From projection area edge, circle sees that illumination is gradually dimmed outward, is remote bright near-dark when being irradiated to ground, but irradiates and must get over distance light back and forth
Visual attenuation is also bigger, so at a distance with nearby brightness of illumination difference and little, to wider at more than 100 meters before lamp
In the range of have clearly bright radiation response.
5th, in summary, this Vehicle lamp structure is simple so that LED makes automobile-used headlight and is more prone to, the light that LED is sent
Directive property is good, so 20 to 30 watts or so of illuminator can just obtain fabulous radiation response, illumination range is appropriate, meets
Vehicling lighting requirement.Due to this lamp free from glare, even if whole when driving use the car light, in the same direction or opposite traveling
Vehicle all without influence, so as to eliminate the harm of existing high beam, drive a vehicle safer.
