Abstract
A car lamp light distribution mirror capable of uniformly emitting light is used for preventing a car lamp from glaring and improving traffic safety. The technical scheme includes that the light distribution mirror comprises an inner light distribution cover and an outer light distribution cover which sequentially cover the outside of a light source, the inner light distribution cover is provided with a Fresnel lens, and the inner side of the outer light distribution cover is provided with refraction stripes. Light is refracted for three times by the aid of decorative patterns on sides of the inner light distribution cover and the outer light distribution cover, so that a signal lamp achieves the light-emitting effect of a surface light source. Compared with a traditional car lamp light distribution mirror, the car lamp light distribution mirror capable of uniformly emitting light is simple in structure, low in cost, attractive in appearance and soft in light emission, avoids glaring light, improves visual comfort, leads the lamp to be more eye-catching after being turned on, and can effectively avoid traffic accidents.
Description
Technical field
The utility model relates to a kind of vehicle lamp light-distributing mirror, and particularly a kind of lens that is applicable to body of a motor car external signal lamp belongs to automobile technical field.
Background technology
Body exterior signal lamp (comprising back-up lamp, steering indicating light, Brake lamp, side-marker lamp etc.) is the signal of interest device of automobile, and its illumination effect directly affects traveling security.Even, soft for the bright dipping that makes light fixture, traditional automobile signal light is provided with the light refraction decorative pattern on reflecting surface, lens, and purpose is to change the propagation path of light through refraction, thereby improves the visual effect of light fixture.But the visual effect of sort signal lamp is unsatisfactory, looks during lamp luminescence to remain bright spot one by one, is similar to spot light; Can not obtain even, the soft light effect that goes out; When the light of this light source was injected in other driver's eyes, easy generation was dazzle the eyes, and influences traffic safety.
Adopt light guide techniques can process the automobile signal light of planar light extracting, but this light fixture difficulty of processing is big, cost is high, also is difficult at present accepted by people.
The utility model content
The purpose of the utility model be to overcome prior art deficiency, provide a kind of simple in structure, with low cost, the emitting uniform vehicle lamp light-distributing mirror.
The said problem of the utility model is realized by following technical scheme:
A kind of emitting uniform vehicle lamp light-distributing mirror is formed with outer light distributing cap by covering on the outside interior light distributing cap of light source successively, and said interior light distributing cap is a Fresnel Lenses, and the medial surface of said outer light distributing cap has the refractive power striped.
Above-mentioned emitting uniform vehicle lamp light-distributing mirror, the medial surface of said interior light distributing cap is provided with the Fresnel Lenses decorative pattern, and lateral surface is provided with the sphere decorative pattern of protrusion.
Above-mentioned emitting uniform vehicle lamp light-distributing mirror, the refractive power striped that is provided with on the medial surface of said outer light distributing cap is the vertical bar decorative pattern, lateral surface is the light face.
The Fresnel Lenses decorative pattern of light distributing cap medial surface is directional light with the anaclasis that light source sends in the utility model utilization; The sphere decorative pattern of light distributing cap lateral surface carries out birefringence to directional light in utilizing; Make divergence of beam; Vertical bar decorative pattern through outer light distributing cap medial surface reflects light for the third time at last, makes signal lamp reach the light effect that of area source.
Compare with traditional vehicle lamp light-distributing mirror, the utility model is simple in structure, with low cost, and it is not only handsome in appearance, and bright dipping is soft, and blinding free light has improved the euphorosia degree, and more eye-catching after light fixture is lighted, the generation that can effectively avoid traffic accident.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the shape of the Fresnel Lenses decorative pattern of interior light distributing cap medial surface;
Fig. 3 is the shape of the sphere decorative pattern of interior light distributing cap lateral surface;
Fig. 4 is the shape of the vertical bar decorative pattern of outer light distributing cap medial surface.
Each label is among the figure: 1, outer light distributing cap; 2, interior light distributing cap; 3, light source.
The specific embodiment
Referring to Fig. 1, the utility model is made up of with interior light distributing cap 2 outer light distributing cap 1, and the medial surface of outer light distributing cap 1 has the refractive power striped; Interior light distributing cap 2 is the Fresnel Lenses light distributing cap.Some groups of Fresnel Lenses decorative patterns are arranged on the Fresnel Lenses light distributing cap medial surface, the sphere decorative pattern of some groups of protrusions is arranged on the lateral surface of minute surface; The refractive power striped that is provided with on the said outer light distributing cap medial surface is the vertical bar decorative pattern, and lateral surface is the light face.
The bright dipping principle of the utility model: the Fresnel Lenses decorative pattern is collected the light that light source sends, and is refracted as directional light, and the sphere decorative pattern carries out birefringence to directional light, and diffused light once more through the refraction for the third time of vertical bar decorative pattern, reaches the light effect that of face.
As can beappreciated from fig. 1, the light that light source 3 sends becomes scattered light after two-layer light distributing cap refraction, and radiation direction has no rule, looks similarly to be to send from lens, promptly has the visual effect of area source.
Use the car light of this lens can obtain evenly to go out light effect, whole lamp is handsome in appearance, and more eye-catching with respect to vehicle and pedestrian after lighting, bright dipping is soft, and blinding free light improves the euphorosia degree, the generation that avoids traffic accident.
The utility model is simple in structure, be easy to through engineering approaches produce in batches, cheap.
