Abstract

The utility model discloses a light-emitting diode (LED) automotive headlamp which comprises a shell body, a lower beam module and an upper beam module, wherein the lower beam module comprises a first reflecting mirror; and the reflecting surface of the first reflecting mirror is a plurality of free-form surfaces which are combined with one another. The LED automotive headlamp solves the technical problem of light distribution of an LED area light source, enables the novel LED area light source to be applied to an automotive headlamp, and gives play to the advantages of energy conservation, long service life, environmental protection, small size, high luminance and the like.

Description

The LED car headlamp

Technical field

The utility model relates to the automotive lighting field of tool, is specifically related to car headlamp.

Background technology

Current car headlamp adopts Halogen lamp LED as illuminating source more, and what adopt on a small quantity is xenon lamp.Halogen lamp LED and xenon lamp all are stereo luminous, and luminous intensity distribution also is the light distributing system that designs according to stereo luminous source.When with LED during as the illuminating source of car headlamp, because LED is that face is luminous, adopt traditional three-dimensional light distributing system can not satisfy the luminous light distribution requirements of face of LED, reduced the optical efficiency of LED.

The utility model content

For this reason, the utility model proposes a kind of new LED car headlamp of at least a portion that can address the above problem, this headlamp improves light distributing system, has fully satisfied the light distribution requirements of LED, realizes that it is energy-conservation, long-lived, environmental protection, little, the brightness advantages of higher of volume.

The utility model provides a kind of LED car headlamp, comprises housing, dipped beam module and distance light module, and described dipped beam module comprises the first speculum, and wherein the reflecting surface of the first reflective mirror is the free form surface of a plurality of combinations.

The form that the reflecting surface of the reflective mirror in the LED car headlamp of the present utility model in the dipped beam module has adopted the multiaspect free form surface to combine has satisfied the higher light distribution requirements of dipped beam module.

Alternatively, described distance light module further comprises the second speculum, and the reflecting surface of described the second reflective mirror is free form surface.

Alternatively, described dipped beam module also comprises led light source, and described the first speculum is at least part of to surround described led light source.Described distance light module also comprises led light source, and described the second speculum is at least part of to surround described led light source.

Alternatively, described dipped headlights and described high beam exterior contour are semicircle.

Because the exterior contour of dipped headlights and high beam all adopts the semicircle form, compares traditional circular contour, volume-diminished half, reduced manufacturing cost.

Description of drawings

By reading hereinafter detailed description of the preferred embodiment, various other advantage and benefits will become cheer and bright for those of ordinary skills.Accompanying drawing only is used for the purpose of preferred embodiment is shown, and does not think restriction of the present utility model.And in whole accompanying drawing, represent identical parts with identical reference symbol.In the accompanying drawings:

Fig. 1 is the structural representation of the utility model LED car headlamp;

Fig. 2 is the perspective view of dipped beam module in the utility model LED car headlamp;

Fig. 3 is the front view of dipped beam module in the utility model LED car headlamp;

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing and concrete embodiment.

The utility model discloses a kind of LED car headlamp, comprise housing, dipped beam module and distance light module, it is characterized in that: described dipped beam module comprises the first speculum, and wherein the reflecting surface of the first reflective mirror is the free form surface of a plurality of combinations.

Described distance light module comprises the second speculum, and the reflecting surface of described the second reflective mirror is free form surface.

Described dipped beam module also comprises led light source, and described the first speculum is at least part of to surround described led light source.Described distance light module also comprises led light source, and described the second speculum is at least part of to surround described led light source.

Fig. 1 shows the structural representation of the utility model LED car headlamp.As shown in Figure 1, the utility model LED car headlamp comprises 3 groups of housing 1,2 groups of dipped headlights and high beams, and described dipped headlights 2 and described distance light module 3 are installed in the housing.Be understandable that described dipped headlights and described distance light module can adopt that any mounting means is installed in the described housing in the prior art, as long as mounting means satisfies the lighting demand of headlamp.

Fig. 2 and Fig. 3 show respectively perspective view and the front view of dipped beam module in the utility model LED car headlamp.As shown in Fig. 2 and Fig. 3, described dipped beam module 2 comprises the first speculum 21 and led light source 4, and the reflecting surface of described the first reflective mirror 21 is free form surfaces of a plurality of combinations.Described the first speculum 21 is at least part of to surround described led light source 4, for example, described led light source can be placed any one focus place of described a plurality of free form surfaces, as long as the light of light source emission can be reflected away.Because the first speculum 21 has the reflecting surface that the free form surface of a plurality of combinations forms, the light of led light source emission can be through a plurality of free form surface reflections, strengthen thus the light intensity that reflects the dipped beam module, thereby satisfied the higher light distribution requirements of dipped beam module.

Fig. 4 and Fig. 5 show respectively perspective view and the front view of distance light module in the utility model LED car headlamp.As shown in Figures 4 and 5, described distance light module 3 comprises the second speculum 31 and led light source 4, and wherein the reflecting surface of the second reflective mirror 31 is free form surfaces.Described the second speculum 31 is at least part of to surround described led light source 4, preferably places the focus place of described free form surface.

Described dipped beam module and described distance light module exterior contour are semicircle.

As shown in Fig. 2 and Fig. 4, the exterior contour of dipped beam module 2 and distance light module 3 all adopts the semicircle form, compares traditional circular contour, volume-diminished half, reduced the shared volume of whole headlamp, also reduced manufacturing cost.

It should be noted that above-described embodiment describes the utility model rather than the utility model is limited, and those skilled in the art can design alternative embodiment in the situation of the scope that does not break away from claims.In the claims, any reference symbol between bracket should be configured to limitations on claims.Word " comprises " not to be got rid of existence and is not listed in element or step in the claim.Being positioned at word " " before the element or " one " does not get rid of and has a plurality of such elements.The use of word first, second and C grade does not represent any order.Can be title with these word explanations.
