Abstract

The utility model discloses a kind of light lens and its LED, including lens body, the body bottom portion is provided with for arranging the containing cavity of light source, it is characterised in that, the lateral wall of the body is reflecting surface, the reflecting surface is in plaited surface, at the top of the containing cavity centered on face, the median plane adopts Fresnel lens structure, the body extension is provided with cubic pyramid convex cosmetic stricture of vagina, this reflection from lens face is designed for mixed light using plaited surface, improves optical quality, eliminates macula lutea；Using Fresnel lens structure form, using the advantage of Fresnel Lenses, angle can be done little, while reducing the thickness of core, reduce the cycle of injection mo(u)lding, substantially increase production efficiency, production cost is reduced, and using cubic pyramid convex cosmetic stricture of vagina, the clear lines that is recessed is seen as from front, exquisite appearance, it is high-end and atmospheric.

Description

A kind of light lens and its LED

Technical field

This utility model is related to lighting field, more particularly to a kind of light lens.

Background technology

It is extremely difficult that existing COB lens do low-angle, and when particularly light-emitting area is larger, central ray is difficult to draw in Accomplish low-angle, and the slightly smaller lens of angle（Less than 24 °）, the thickness of product remains high, the grammes per square metre of the whole product for being Very big, injection mo(u)lding is difficult, and the cycle is long.

Utility model content

The purpose of this utility model is to provide a kind of low-angle, center thin light lens, and using the lens LED, to solve the problems, such as to propose in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme：

A kind of light lens, including lens body, the body bottom portion are provided with for arranging the containing cavity of light source, described The lateral wall of body is reflecting surface, and the reflecting surface is in plaited surface, at the top of the containing cavity centered on face, the median plane adopts Fresnel lens structure, the body upper end-face edge are provided with extension, and the extension is provided with cubic pyramid convex cosmetic stricture of vagina.

Preferably, the lens body is transparent PC materials.

A kind of LED, including light source and the light lens described in claim 1, the light source are arranged on the lens sheet The accommodating intracavity of body.

Compared with prior art, the beneficial effects of the utility model are：This reflection from lens face is designed for mixing using plaited surface Light, improves optical quality, eliminates macula lutea；Using fresnel（Fresnel Lenses）Version, using the excellent of Fresnel Lenses Angle can be done little by point, while reducing the thickness of core, reduce the cycle of injection mo(u)lding, substantially increase production effect Rate, reduces production cost, and using cubic pyramid convex cosmetic stricture of vagina, is seen as the clear lines that is recessed from front, and exquisite appearance is high End air.

Specific embodiment

Below the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described reality Apply the example only a part of embodiment of this utility model, rather than the embodiment of whole.Based on the embodiment in this utility model, The every other embodiment obtained under the premise of creative work is not made by those of ordinary skill in the art, belongs to this reality With novel protected scope.

Fig. 1 and Fig. 2, a kind of light lens, including lens body 1 are referred to, 1 bottom of the body is provided with for arranging light The containing cavity 11 in source 6, the lateral wall of the body is reflecting surface 2, and the reflecting surface 2 is in plaited surface, at the top of the containing cavity Centered on face 3, the median plane 3 adopts Fresnel lens structure, 1 upper end-face edge of the body to be provided with extension 4, the extension Portion 4 is provided with cubic pyramid convex cosmetic stricture of vagina 5, and this reflection from lens face 2 is designed for mixed light using plaited surface, improves optical quality, disappears Except macula lutea；Median plane 3 adopts fresnel（Fresnel Lenses）Version, using the advantage of Fresnel Lenses, can be by angle Do little, while reducing the thickness of core, reduce the cycle of injection mo(u)lding, substantially increase production efficiency, reduce production Cost；Using cubic pyramid convex cosmetic stricture of vagina 5, the clear lines that is recessed is seen as from front, exquisite appearance is high-end and atmospheric.

Preferably, the lens body 1 is transparent PC materials.

A kind of LED, including light source 6 and light lens of the present utility model, the light source 6 are arranged on the lens body In 1 containing cavity 11, the LED for applying this utility model lens can accomplish low-angle, and hot spot is uniform.

Although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art comes Say, which still can be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered Row equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. all should It is included within protection domain of the present utility model.
