Abstract

The utility model relates to the technical field of a lens, in particular to an LED secondary optical lens. The LED secondary optical lens is composed of an incidence end, a base body end and a refraction end which are formed in an integral manner. The base body end is arranged between the incidence end and the refraction end, the surface of the refraction end is a non-spherical curved surface, the front and rear sides of the refraction end are protruded over the base body end to form a lug boss curved surface, and the left and right sides of the refraction end are indented into the base body end to form a groove curved surface. The LED secondary optical lens can effectively improve the light condensing effect and light efficiency, and can satisfy the requirements of road design installation standards for the irradiation range.

Description

The LED secondary optical lens

Technical field:

The utility model relates to the lens technologies field, relates in particular to the 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: the LED secondary optical lens, it is made up of integrated incident end, matrix end and refraction end, the matrix end is between incident end and refraction end, the surface of described refraction end is a non-spherical surface, the both sides, front and back of refraction end are protruded the matrix end and are formed the boss curved surface, and the recessed matrix end in the left and right sides of refraction end forms the groove curved surface.

Described matrix end is the planar lens shape.

Described incident end is the planar lens shape.

Four jiaos of described matrix end is rounding.

The utility model beneficial effect is: the surface of the refraction end of LED secondary optical lens described in the utility model is a non-spherical surface, the both sides, front and back of refraction end are protruded the matrix end and are formed the boss curved surface, the recessed matrix end in the left and right sides of refraction end forms the groove curved surface, 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 another visual angle structural representation of the present utility model;

Fig. 3 is a vertical view of the present utility model;

Fig. 4 is the A-A cutaway view of Fig. 3;

Fig. 5 is the B-B cutaway view of Fig. 3.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

Extremely shown in Figure 5 as Fig. 1, the LED secondary optical lens, it is made up of integrated incident end 3, matrix end 2 and refraction end 1, matrix end 2 is between incident end 3 and refraction end 1, the surface of described refraction end 1 is a non-spherical surface, the both sides, front and back of refraction end 1 are protruded matrix end 2 and are formed boss curved surface 4, and the recessed matrix end 2 in the left and right sides of refraction end 1 forms groove curved surface 5.Described matrix end 2 is the planar lens shape.Described incident end 3 is the planar lens shape.Four jiaos of described matrix end 2 is rounding, makes things convenient for the setting-in of this LED secondary optical lens.

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 3, enter refraction end 1 through matrix end 2 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.
