Embodiment Construction

[0018] The invention will now be described with reference to the accompanying drawings

[0019] figure 1 A perspective view showing an LED optical lens according to an exemplary embodiment of the present invention, as figure 1 shown. It consists of LED light source 1, LED light source beam front incident surface 2, LED light source beam front exit surface 3, side incident surface (4), LED light source left and right side total reflection beam control surface 5, LED light source front and rear side beam total reflection control Surface 6 and side exit surface 7. Part of the light beam emitted by the LED light source is refracted and regulated through the front incident surface 2 of the LED light source beam and the front exit surface 3 of the LED light source beam, and the other part of the light beam emitted by the LED light source mainly passes through the side incident surface 4, Left and right side beam total reflection control surfaces 5, front and rear side beam total r...

Abstract

The invention discloses an LED-based beam shaping lens, which is characterized in that it consists of an LED light source 1, an LED beam incident surface 2, an LED beam exit surface 3, an LED left and right side beam control surface 4, and an LED front and rear side The beam control surface 5 is composed. Part of the beam emitted by the LED is regulated through the beam incident surface 2 and the beam exit surface 3 , and the other part of the beam emitted by the LED is mainly regulated through the side beam total reflection control surface 4 and the side beam total reflection control surface 5 . The microstructure is mainly used to generate a rectangular spot distribution pattern.

Description

Technical field [0001] The invention relates to an LED-based light beam shaping lens. The optical lens can output all spherical light beams emitted by LED chips as rectangular light beams. Background technique [0002] Under the theme of the era of environmental protection and energy saving, the new light source—high-power LED lighting is becoming more and more popular in the world. The new darling of the high-power LED lighting industry brings new advantages to traditional lighting fixtures with its unique quality, environmental protection, energy saving, and long life. A great revolution in human history. [0003] As a product of a new application field, LED new light source has its own excellent quality, but it still has its limitations and parts that need to be improved in the field of lighting to replace traditional sodium lamps and fluorescent lamps. Due to its small size and small light-emitting surface, it is difficult to control the light transmission process of th...
