Description
Technical Field

Background
The LED module is as a current illuminator commonly used, by the wide use in each illumination, and the LED module generally includes LED lamp pearl and optical lens, can see out through LED's theory of operation, because LED lamp pearl is to emitting light all around, so only partial light can see through one deck and receive light lens, and partial light can shine on the panel beating surface of receiving light lens still. The surface of the existing metal plate is subjected to sand blasting and oxidation treatment, so that the surface is not smooth and the reflectivity is low. Therefore, the part of the light rays are not reflected to a layer of light-receiving lens again through multiple reflections. Even if the part of light is reflected to a layer of light-receiving lens, most part of the light is lost in the reflection process, and the lost part is finally diffused inside the module in a thermal mode, so that the module is easy to overheat, the luminous energy efficiency is influenced, and the part of light is lost and cannot be utilized. A certain distance exists between the fly-eye lens and the lenticular lens. Therefore, in the process that light rays pass through the fly-eye lens and reach the double-convex lens, part of the light rays can still irradiate the inner wall surface of the double-convex lens fixing metal plate, and the reflectivity of the inner wall surface facing the light rays is low, so that the light ray utilization rate is low.
For example, CN202122635676.6, its patent application number discloses a lighting device, which comprises a housing, and an LED array, a collimating system and a condenser lens sequentially disposed in the housing, wherein a fly-eye structure or an optical diffusion structure is integrally formed on a light-emitting surface of the condenser lens. The compound eye structure or the optical diffusion structure is integrally formed on the light-emitting surface of the condenser lens, so that the functions of condensing and homogenizing light on the same optical part are realized. The design not only saves the cost of the fly-eye lens optical piece/the optical diffusion sheet, but also reduces the position for installing the fly-eye lens/the optical diffusion sheet, reduces the volume of the lighting device, avoids the loss efficiency of light rays passing through an optical interface, has the optical effect of the fly-eye lens/the optical diffusion structure and improves the efficiency of an optical system. But there can be the distance between this structure collimating lens array and the light source, because the inner wall reflects light to make partial light lose the reflectivity low owing to the reflection, so this partial light will lose, thereby reduced the light efficiency, simultaneously because the light that the light source sent can't reflect away after blocking to reflect to the base plate, thereby cause the light loss, thereby reduce the light efficiency.
