Embodiment Construction

[0014] The invention will now be described with reference to the accompanying drawings

[0015] 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 beam front incident surface 2, LED beam front exit surface 3, side incident surface 4, LED left and right side total reflection beam control surface 5, LED front and rear side beam total reflection control surface 6, side exit surface 7 composition. The central beam emitted by the LED is refracted and regulated through the beam incident surface 2 and the beam exit surface 3. The beam incident surface 2 is mainly used to homogenize the light in the X direction and re-modulate the energy; while the exit surface 3 is mainly used for the center light Homogenization or energy regulation is carried out in the Y direction, and the large-angle light emitted by the LED is mainly transmitted through the side incide...

Abstract

The invention discloses a light beam shaping lens based on an LED. The light beam shaping lens is characterized by comprising an LED light source 1, an LED light beam incident plane 2, an LED light beam emergent plane 3, an LED lateral sideway light beam control plane 4, and an LED longitudinal sideway light beam control plane 5, wherein one part of the light beam sent by the LED is adjusted through the light beam incident plane 2 and the light beam emergent plane 3; the other part of the light beam sent by the LED is primarily controlled by the sideway light beam total reflection control plane 4 and the sideway light beam total reflection control plane 5. The micro-structure provided by the invention is mainly applied to the generation of a pattern with distributed rectangular light spots.

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...
