Abstract
The utility model relates to a lens discloses a lens for LED car light, including the lens main part, there is a sunken hemisphere incident surface lens main part bottom, lens main part top is the bellied emitting surface of three ellipsoid that the axis is parallel, lens main part side is the arc plane of reflection. The utility model has the advantages of make LED luminous even, shine the angle big.
Description
Technical field
The utility model relates to lens, especially relates to the LED car light that a kind of LED of making is luminous evenly, irradiating angle is big and uses lens.
Background technology
Car light is automobile " eyes ", and it has two kinds of basic functions: illumination and decoration.The light of car has comprised night flight or navigation side-marker lamp, signal lamp, fog lamp, night flight or navigation illuminating lamp etc., and the quality of their use and state of the art directly has influence on the safety of driving.LED is because its energy-efficient characteristic is replacing the use of former incandescent lamp bulb in car light.In the LED lighting engineering, generally adopt the combined formation led light source of cold light source and convex lens.At present, the lens that adopted are all comparatively thick big, mainly stress the optically focused effect; This light fixture luminous energy attenuation is relatively large; It is in order to reach stronger optically focused purpose, forms center light according to the strong and more weak hot spot in edge, certainly will cause user available field of view less and the illumination sudden change is more obvious.And for being applied on the car light, it requires, and luminous intensity is even, irradiating angle is big.Therefore, present employing cold light source and the combined formation led light source of the convex lens requirement that can't satisfy car light.
Summary of the invention
For overcoming above-mentioned shortcoming, the utility model purpose is to provide the LED car light that a kind of LED of making is luminous evenly, irradiating angle is big to use lens.
The utility model is realized through following technical measures; A kind of LED car light is used lens, comprises lens body, and the hemisphere face plane of incidence of a depression is arranged at said lens body bottom; Said lens body top is provided with the protruding exit facet of three ellipsoids, and said lens body side is a curved reflecting surface.
As a kind of optimal way, the ellipsoid on two limits, said lens body top is higher than middle ellipsoid and is symmetrical structure.
As a kind of optimal way, reflective membrane is posted or scribbles on said reflecting surface surface.
The preferred light transmittance of said lens body is greater than 93% optical glass lens or PMMA lens.
The utility model disperses the some light that LED sends to inject in the lens body by the plane of incidence; Middle stronger light is gone out from the less ellipsoid flat fire of center of top; The light on two limits from the top the bigger ellipsoid flat fire in two limits go out; The light of side through the reflecting surface reflection after also from the top the bigger ellipsoid flat fire in two limits go out, thereby whole light is evenly dispersed, reach the effect that luminous intensity is even, irradiating angle is big.
Description of drawings
Fig. 1 is the vertical section structural representation of the utility model embodiment;
Fig. 2 is the plan structure sketch map of the utility model embodiment.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is done further explain.
Like Fig. 1, Fig. 2; A kind of LED car light is used lens; Comprise the optical glass lens main body, the hemisphere face plane of incidence 4 of a depression is arranged at the lens body bottom, and the lens body top is the protruding exit facet of three ellipsoids of parallel axes; Wherein the ellipsoid 2 on two limits is higher than middle ellipsoid 1 and is symmetrical structure, and said lens body side is the curved reflecting surface 3 that scribbles reflective membrane.
More than be that the utility model LED car light is set forth with lens; Be used for helping to understand the utility model; But the embodiment of the utility model is not restricted to the described embodiments; Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection domain of the utility model.
Claims (4)
1. a LED car light is used lens; Comprise lens body; It is characterized in that: the hemisphere face plane of incidence of a depression is arranged at said lens body bottom, and said lens body top is provided with the parallel protruding exit facet of three ellipsoids, and said lens body side is a curved reflecting surface.
