Design and die processing of LED lens
Apr 18, 2018

1. first depends on the light source (high power LED), different brands of large power LED (such as CREE, Lumileds, Seoul, OSRAM, 100 million light, Ai Disen, Chang Sen source, etc.), its chip structure and packaging mode, light characteristics and so on will be different, resulting in the same lens with different specifications of the brand LED when the difference in the clubhouse Therefore, we need to develop targeted (mainstream brand oriented), so as to achieve the desired results.

2. the design and optical simulation of optical design software (such as Code V, ZEMAX, TracePro, ASAP, LighTools, etc.) and mechanical modeling software (such as Pro/E, UG, SOLIDWORKS, etc.) are carried out and the corresponding optical lenses are continuously optimized.

3.LED lens itself is a precision optical accessory, so its accuracy is very high for the mold, especially for the optical surface machining accuracy of the lens to reach 0.1 M. In general, the machining of such high precision die must have the following equipment: ultra precision machining machine (such as PRECITECH NANOFORM 350), CNC integrated machine, precision grinding machine, precision milling machine, drilling machine, CNC precision spark machine, surface profilometer, interferometer and so on.

4. die is the optical mold kernel. First of all, we must choose the special mold kernel steel (such as the Swedish S136 mirror steel) to finish the rough embryo through heat treatment to 55 degrees, and then process it with a super precision machine after the nickel plating on the rough embryo.
