Description

Vehicle head lamp

Technical field

The utility model is related to vehicle head lamp, and it includes the light for the first quantity being installed on the first printed circuit board (PCB) Source, the light source for the second quantity being installed on the second printed circuit board (PCB), for reflecting the light that the radiation of light source of first quantity goes out The first reflector, the second reflector, cooling element and Gai Jing for reflecting the light that the radiation of light source of second quantity goes out Piece；Wherein the cooling element is T-shaped, with the first arm and the second arm, and wherein second arm is vertical fixed with respect to first arm To, wherein the first arm of the cooling element extends between the first and second reflectors.

Background technology

Common vehicle head lamp be generally based on to its light distribution and the criterion of form that shows it and design. Many vehicle head lamps include light source and reflector, so that based on the lid eyeglass in front of the light source and covering reflector to create The light distribution of certain determination.In some cases, can occur frosting and atomization on lid lens surface so that lowering the lid eyeglass Light transmittance.

In order to solve this problem, according to prior art, some vehicle head lamps include heating element heater, have been all and have covered this Eyeglass warms with defrosting or defogging.Other vehicle head lamps include cleaning element to remove frost and snow from the outer surface of lid eyeglass. These vehicle head lamps are expensive, also easily errors, because they need extra driving member.

Utility model content

Therefore a purpose of the present utility model, which is to provide, belongs to the foregoing vehicle head lamp of that, and it overcomes prior art Shortcoming.

In order to reach this purpose, according to the utility model, it will refer to that the vehicle head lamp of that further develops when starting, This is to be that first and second printed circuit board (PCB) is installed on the two opposite sides of the first arm of the cooling element, and wherein this is cold But the second arm of element in this first and the second reflector rear extension, and the lid eyeglass is in before first and second reflector Extension, wherein being provided with fan in the back side of the second arm of the cooling element to cool down the cooling element, and is wherein free conductance to draw Element is arranged on the fan, and the air guide element is configured to guide the air by fan toward the lid eyeglass.

With according to vehicle head lamp of the present utility model, the heat energy gone out from the radiation of light source of vehicle head lamp be used to keep away Exempt from the frosting of lid eyeglass or atomization.After offer avoids the sane scheme of the frosting of lid eyeglass or atomization, this also allows light simultaneously Source is preferably cooled down, so as to extend the life-span of those light sources.

Preferably, the cooling element can be made up of copper or aluminium.

Advantageously, the air guide element can be made of plastics.

Preferably, each light source is LED/light source.

Brief description of the drawings

, will more clearly specific feature and advantage of the present utility model by the following description.Referring in accompanying drawing Shown in exemplary embodiment (it is not construed as restricted) the utility model is described in more detail, wherein：

Fig. 1 is the sectional view according to vehicle head lamp of the present utility model；

Fig. 2 is the perspective view that Fig. 1 vehicle head lamp is in the part in the state of disintegrating；
