Description

Improved vehicle LED reflection type headlamp

Technical Field

The utility model relates to a modified automobile-used LED reflection formula headlight.

Background

The reflective headlamp is very commonly used on a vehicle, generally an LED lamp is used as a light source, and light emitted by the LED light source is converged and reflected to a road surface under the action of a reflecting bowl to form an illumination surface; because the LED light source is divergent, part of light beams can not irradiate the reflecting bowl (the part of light beams are described as stray light), the stray light irradiates the road surface and is combined with the light beams reflected by the reflecting bowl, so that the road surface irradiation is uneven, and the visual fatigue of a driver is easily caused; in the prior art, a shading method is generally adopted to shade the stray light, so that partial light beam waste is caused.

SUMMERY OF THE UTILITY MODEL

To the weak point that exists in the above-mentioned problem, the utility model provides a modified automobile-used LED reflection formula headlight.

In order to achieve the above object, the present invention provides an improved vehicle LED reflective headlamp, which includes a mounting bracket, wherein the mounting bracket is provided with an LED light source, a reflector and a light-passing plate, and the light-passing plate is used for collecting and refracting light beams that do not irradiate onto the reflector;

through the effect of the light transmitting plate, the light pollution caused by wasted light beams which are not irradiated on the reflecting surface of the reflecting type headlamp part is solved, the wasted light beams which are not irradiated on the reflecting surface of the reflecting type headlamp part are recycled, stray light irradiated on a road surface is orderly arranged, the road surface is irradiated more uniformly, and the visual fatigue of a driver is reduced.

Preferably, the optical surface of the light-transmitting plate is composed of multiple curved surfaces;

in the technical scheme, the path of the light beam passing through the light-transmitting plate is reasonably adjusted by the design of the multiple curved surfaces, so that the illumination surface is more uniform.

Preferably, the light reflecting bowl is divided into an upper chamber and a lower chamber by a partition plate, and the upper chamber and the lower chamber are both internally provided with the LED light source and the light-transmitting plate;

in the technical scheme, the upper chamber and the lower chamber are designed for the reflector, so that the requirement that the automotive LED reflection type headlamp is provided with the independent high beam lamp and the independent dipped headlight is met.

The utility model discloses beneficial effect for prior art does: for the treatment of the stray light of the reflective LED vehicle lamp, the prior art adopts a shading method to cause partial waste of light beams, and meanwhile, the illumination surface is not uniform.

Detailed Description

As shown in fig. 1 to 3, an improved vehicle LED reflection type headlamp according to an embodiment of the present invention includes a mounting bracket 1, the mounting bracket 1 is provided with an LED light source 2, a reflector 4 and a light-transmitting plate 3, and the light-transmitting plate 3 is used for collecting and refracting a light beam that does not irradiate the reflector 4; the optical surface of the light-transmitting plate 3 is composed of multiple curved surfaces, and the path of light beams passing through the light-transmitting plate is reasonably adjusted through the design of the multiple curved surfaces, so that the illumination surface is more uniform; the reflector 4 is divided into an upper chamber 41 and a lower chamber 42 by a partition plate, the upper chamber 41 and the lower chamber 42 are both internally provided with the LED light source 2 and the light-transmitting plate 3, and the upper chamber and the lower chamber are designed to meet the requirement that the automotive LED reflective headlamp is provided with an independent high beam lamp and an independent low beam lamp.

For the treatment of the stray light of the reflective LED vehicle lamp, the prior art adopts a shading method to cause partial waste of light beams, and meanwhile, the illumination surface is not uniform.

When in specific use, the utility model is described with the attached drawings for the convenience of understanding;

as shown in fig. 3, stray light cannot irradiate the inner wall surface of the reflector, the path of the stray light beam is adjusted under the action of the light transmitting plate and irradiates the road surface again, so that the utilization of the stray light is realized, the light utilization rate is improved, and meanwhile, the irradiation of the road surface is more uniform through the adjustment of the stray light path, and the fatigue of a driver can be effectively relieved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
