Abstract
The utility model relates to a LED ball bubble lamp lens, which comprises a lens body, the upper portion of lens body wholly is the drum type, and the top surface outside -in of lens body reduces gradually, and the top surface of lens body is stupefied face, open at the top surface center of lens body has circular recess A, circular recess A's cross section diameter is followed up crescently down. The utility model discloses the light that divides the light source into two directions is dealt with differently, handles big angle direction with central light to the light ratio that improves big angle direction is heavy, thereby it is heavy to handle the light ratio that reduces little angle direction with border light total reflection.
Description
Technical field
The utility model relates to field of illuminating lamps, particularly relates to a kind of LEDbulb lamp lens.
Background technology
At present, LEDbulb lamp is that the refraction of scioptics and total reflection realize, but due to the light ratio in wide-angle direction heavy less, center light is more, well can not reach the effect of wide-angle bulb lamp.
Utility model content
The utility model aims to provide a kind of LEDbulb lamp lens, carries out total reflection process, realize wide-angle and send light the light that LED light source sends.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of LEDbulb lamp lens, comprise lens body, and the top entirety of described lens body is in drum type, and the end face ecto-entad of lens body reduces gradually, and the end face of lens body is stupefied; The end face center of described lens body has circular groove A, and the cross-sectional diameter of described circular groove A increases from the bottom up gradually.
Preferably, the bottom surface on described top connects ground floor lens, the waist of described ground floor lens is toward evagination, the cross section of described ground floor lens is circular, there are circular groove B in the bottom surface central authorities of described lens body, and circular groove B from inside to outside diameter increases, and the bottom of described circular groove B is arranged in ground floor lens, circular groove B bottom surface is the curved surface of evagination, described ground floor lens and top dead in line.
Preferably, the bottom surface of described ground floor lens connects second layer lens, the waist of described second layer lens is toward evagination, the cross section of described second layer lens is circular, the end face of described second layer lens is the bottom surface of ground floor lens, the maximum gauge of second layer lens is less than the maximum gauge of ground floor lens, described second layer lens and the dead in line of ground floor lens.
Further, one section of side of described circular groove B opening part is the curved surface of indent.
Further, described lens body bottom peripheral edge is equidistantly provided with four assembly walls.
Compared with prior art, the utility model has following beneficial effect:
Light light source being divided into both direction processes respectively, by central ray process to wide-angle direction, thus improves the light ratio weight in wide-angle direction, and boundary rays processes through total reflection thus reduces the light ratio weight in low-angle direction.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is boundary rays by the light path schematic diagram of ground floor lens in the utility model and the bright dipping of second layer lens;
Fig. 3 is the light path schematic diagram of central ray by lens body top bright dipping in the utility model;
In figure: 1-top, 2-circular groove A, 3-ground floor lens, 4-second layer lens.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, disclosed in the utility model, a kind of LEDbulb lamp lens, comprise lens body, and top 1 entirety of lens body is in drum type, and the end face ecto-entad of lens body reduces gradually, and the end face of lens body is stupefied; The end face center of lens body has circular groove 2, the cross-sectional diameter of circular groove 2 increases from the bottom up gradually, preferably, the bottom surface on top 1 connects ground floor lens 3, the waist of ground floor lens 3 is toward evagination, the cross section of ground floor lens 3 is circular, there are circular groove B in the bottom surface central authorities of lens body, circular groove B from inside to outside diameter increases, the bottom of described circular groove B is arranged in ground floor lens 3, circular groove B bottom surface is the curved surface of evagination, described ground floor lens 3 and top 1 dead in line.Preferably, the bottom surface of ground floor lens 3 connects second layer lens 4, the waist of second layer lens 4 is toward evagination, the cross section of described second layer lens 4 is circular, the end face of described second layer lens 4 is the bottom surface of ground floor lens 3, the maximum gauge of second layer lens 4 is less than the maximum gauge of ground floor lens 3, second layer lens 4 and ground floor lens 3 dead in line.Further, one section of side of circular groove B opening part is the curved surface of indent, and lens body bottom peripheral edge is equidistantly provided with four assembly walls.
As shown in Figure 1, 2, 3, during use, light source is placed in immediately below lens body, preferably light source is located in lens body bottom groove, light source can rotate arrangement by many surface-mounted LED light sources and be formed, the light that light source sends is divided into central ray and boundary rays, after the top 2 of central ray scioptics body is tightened up, prism facets through end face is totally reflected away, improve the light ratio weight in wide-angle direction, boundary rays is totally reflected process to wide-angle direction by ground floor lens 3 and second layer lens 4, decreases the light ratio weight in low-angle direction.Boundary rays total reflection process to wide-angle direction, is decreased the light ratio weight in low-angle direction, enhances wide-angle direction light proportion greatly by central ray process by the utility model.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
