Abstract
The utility model relates to the technical field of lenses, in particular to an LED secondary optical lens, which is composed of an incident end and a refractive end which are molded integrally, wherein the refractive end is arranged above the incident end, the surface of the refractive end is a non-spherical surface camber, and the refractive end exposes to the incident end to form a boss. The utility model can effectively increase condensation effect, increase lighting effect, and meet requirements of road design mounting standards to irradiation range.
Description
Technical field:
The utility model relates to the lens technologies field, relates in particular to a kind of LED secondary optical lens.
Background technology:
The high-power LED light source street lamp is a kind of emerging energy-saving and environmental protection street lamp, is usually used in the urban construction.This street lamp generally uses the LED secondary optical lens to carry out optically focused and leaded light, according to the distribution curve flux of the angle design LED secondary optical lens of different high-power LED light source emergent lights, to increase optical reflection, promotes the light effect that of led light source.Existing LED secondary optical lens, spotlight effect is not ideal enough, can not satisfy the street lamp requirement.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, and a kind of LED secondary optical lens is provided, and this LED secondary optical lens can effectively improve spotlight effect, improves light efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of LED secondary optical lens, and it is made up of integrated incident end and refraction end, and the refraction end is positioned at incident end top, the surface of described refraction end is a non-spherical surface, and the refraction end protrudes the incident end and forms boss.
Described incident end is the planar lens shape.
The right-hand member of described incident end is provided with raised line, and the left end of incident end is provided with the groove that adapts with raised line.
The utility model beneficial effect is: LED secondary optical lens described in the utility model is made up of integrated incident end and refraction end, the surface of refraction end is a non-spherical surface, the refraction end protrudes the incident end and forms boss, adopt this special distribution curve flux design, effectively improve spotlight effect, improve light efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the B-B cutaway view of Fig. 2.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figures 1 to 4, a kind of LED secondary optical lens, it is made up of integrated incident end 2 and refraction end 1, and refraction end 1 is positioned at incident end 2 tops, and the surface of described refraction end 1 is a non-spherical surface, and refraction end 1 protrudes incident end 2 and forms boss 3.Described incident end 2 is the planar lens shape.
The right-hand member of described incident end 2 is provided with raised line 4, the left end of incident end 2 is provided with the groove 5 that adapts with raised line 4, the groove 5 of an above-mentioned LED secondary optical lens and the raised line 4 of another above-mentioned LED secondary optical lens can be halved together, therefore can be applicable to the assembly unit of a plurality of above-mentioned LED secondary optical lens, satisfy the illumination Design requirement of street lamp.
LED secondary optical lens described in the utility model adopts above-mentioned special distribution curve flux design, the emergent light of high-power LED light source is injected incident end 2, enter refraction end 1 again, in refraction end 1, finish optically focused effect to emergent light, can effectively improve spotlight effect, improve light efficiency, can satisfy of the requirement of highway layout installation code range of exposures.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
