Abstract

The utility model discloses an LED illumination lens which is characterized in that a three-dimensional mechanical structure of a single lens optical unit of the lens is in mirror symmetry in one direction, the two asymmetric sides of the lens are used for achieving asymmetric deflection of most energy of an LED light source, the lens optical unit is composed of an upper optical hook face, a connection structure and a lower optical hook face, the LED light source sends out light energy from the lower optical hook face (3), the gradient of one asymmetric side of the upper optical hook face is small, the gradient of the other side of the upper optical hook face is large, and light energy is deflected to the side with large gradient. The LED illumination lens has the advantages that lamp efficiency is high, and the LED illumination lens can be diversely applied to different lamps.

Description

A kind of LED illuminating lens

Technical field

The utility model relates to field of semiconductor illumination, is specifically related to a kind of LED illuminating lens.

Background technology

LED is as a kind of novel environment friendly light source, is being applied in more and more widely that TV is backlight, in general illumination, automobile lighting.At present, illuminating optical lens product is all that symmetrical luminous intensity distribution distributes with dealer's conventional lenses, and on the light fixture that is arranged on a kind of structure that can only be single, applicable illuminated field composition and division in a proportion is limited to.In addition, all LED light sources all can be installed corresponding lens, could obtain necessary light distribution requirements, and light fixture optical energy utilization efficiency is lower.

Summary of the invention

In order to address the deficiencies of the prior art, the utility model provides a kind of LED illuminating lens, can realize the asymmetric deflection of the most of energy of LED light source, and requires accurate distribution light energy according to road illumination standards.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LED illuminating lens, it is characterized in that: the three-dimensional machinery structure of the single lens optical unit of described lens in one direction mirror image is symmetrical, the asymmetrical both sides of described lens are used for realizing the asymmetric deflection of the most of energy of LED light source, described optics of lens unit is by upper optical surface, syndeton, lower optical surface three parts form, described LED light source sends light energy from lower optical surface 3, described upper optical surface is less in an asymmetrical N-Side surf gradient, larger at an other side slope degree, the larger side of the gradient is exactly a side of light energy deflection.

The beneficial effects of the utility model are: the utility model lens have advantages of that Luminaire efficiency is high, can variation apply to different lamps.
