Description
Technical field
The utility model relates to a kind of automobile lamp, relates in particular to a kind of LED car light that sends uniform light.
Background technology
Light that automobile LED signal lamp sends is most to be that it visually is bright spot one by one that discontinuous point-like line, this light are reflected to driver or pedestrian, easily the driver is caused dazzlingly, influences traffic safety.Along with the development of automotive engineering, the automobile LED signal lamp technology is also constantly improved, overcome can not uniformly light-emitting shortcoming.The automobile LED car light adopts LED to cooperate optical fiber, LED to cooperate light-guide material, LED to cooperate three kinds of modes of optical unit structure luminous more at present.But also there is shortcoming in these three kinds of modes, and LED cooperates optical fiber mode majority to be applied to indoor atmosphere lamp, like instrument panel lamp, ornament lamp, warning light, but because light-emitting area is limited, seldom is applied on the signal lamp.LED cooperates the light-guide material mode to be well positioned to meet the moulding demand, but strict to the optical characteristics of light-guide material, and cost is higher.It is to realize uniformly light-emitting through refraction, scattering that LED cooperates the optical unit frame mode, but this mode optical texture is complicated, and die manufacturing cost is higher.
The utility model content
Be to solve the deficiency that exists in the prior art, but the utility model provides a kind of LED car light of uniformly light-emitting, it is simple in structure, handsome in appearance, cheap, be easy to through engineering approaches produces in batches.
Be to realize above-mentioned purpose, the LED car light of the utility model, comprise a plurality of spacing settings led light source, be positioned at the lens of led light source top; First plane of refraction that said lens has near led light source reaches second plane of refraction away from led light source; Said second plane of refraction passes through joint group by a plurality of free form surfaces of and corresponding each led light source setting identical with led light source quantity; The scope angle light that each led light source sends forms range of refractive light after the refraction of first plane of refraction, the free form surface refraction that the free form surface that the boundary rays warp of this range of refractive light is corresponding with this led light source is adjacent.
As the qualification to the utility model, first plane of refraction has the mirror shape that matches with the vehicle body curve.
As the qualification to the utility model, said first plane of refraction is a curved surface.
As the qualification to the utility model, first plane of refraction is the plane.
As to aforesaid way qualification, the curvature of each free curved surface of said composition second plane of refraction is identical.
As the qualification to the utility model, described free form surface is a frosting.
Adopt as above-mentioned technical scheme, the light that led light source sends is after the free form surface refraction corresponding with it, and the light that is positioned at the free form surface middle part is comparatively intensive; And the light that is positioned at curved edges is comparatively sparse; Make the boundary rays warp free form surface adjacent free form surface refraction corresponding of range of refractive light, sparse light is remedied, finally form the effect of even bright dipping with this led light source; Can not cause the driver dazzling, the generation that avoids traffic accident.Its overall structure is simple, handsome in appearance, cheap, be easy to the characteristics that through engineering approaches is produced in batches.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify:
Fig. 1 is the utility model embodiment one overall structure sketch map;
Fig. 2 is the lens structural representation;
Fig. 3 is the principle of luminosity figure of structure shown in Figure 1;

Among the figure: 1, led light source; 2, lens; 3, first plane of refraction; 4, free form surface.
The specific embodiment
Embodiment one
In the LED Vehicle lamp structure by the utility model embodiment shown in Figure 1, it comprises the led light source 1 and the lens 2 that is positioned at led light source 1 top of six spaced sets.Lens 2 has near first plane of refraction 3 of led light source 1 and away from second plane of refraction of led light source 1; First plane of refraction 3 is the plane; Second plane of refraction passes through joint group by six identical free form surfaces 4 of curvature and becomes (as shown in Figure 2), and free form surface 4 be a frosting, and the equal led light sources 1 of correspondences of each free form surface 4, each free form surface 4 be positioned at led light source 1 directly over, the central lines of the two.
Explain as follows in the face of the operation principle of present embodiment structure down:
As shown in Figure 3, led light source 1 sends a branch of scope angle light, and the angular range of this light is α; It is the range of refractive light of β that light forms angle through certain distance through first plane of refraction, 3 generations refraction for the first time; Refraction for the second time takes place in the free form surface 4 through second plane of refraction then, is free form surface owing to produce the face of refraction for the second time, has realized dispersing of birefringence scope light; And then it is comparatively intensive to form the light that is positioned at the free form surface middle part; And the light that is positioned at the free form surface both sides is comparatively sparse, at this moment, because the free form surface adjacent free form surface refraction corresponding of the boundary rays warp of range of refractive light with this led light source; (range of refractive light reflects through the place of passing through mutually of adjacent two free form surfaces shown in figure); Make this boundary rays after refraction, the sparse light on adjacent free form surface both sides is remedied, finally make the whole uniform light shape that forms.
Embodiment two
By shown in Figure 4, in the present embodiment, led light source 1 is a plurality of; Overall structure is provided with (like light for vehicle) along the vehicle body curve; It all can see the light that led light source 1 sends in order to guarantee rear view of vehicle, side, and first plane of refraction 3 is a curved surface, and is provided with along the vehicle body curve; Accordingly; Second plane of refraction of being made up of a plurality of free form surfaces has and first plane of refraction, 3 corresponding curve trends, so that the light that led light source 1 sends forms the boundary rays of range of refractive light after 3 refractions of first plane of refraction, warp reflects with these led light source 1 corresponding free form surface 4 adjacent free form surfaces.
