Design points of LED lenses

led lens is a product used on LED lights to increase its strength, but how was it designed?
1. It mainly depends on the light source (high-power LED), and different brands of high-power LED will have differences in chip structure, packaging methods, light characteristics, etc., and then form the same lens. When different standard brands of Led Lighting Lens are used, there will be differences. Therefore, targeted development (guided by mainstream brands) is required to meet actual needs.
2. Use optical design software to design and simulate optical running, and design corresponding optical aspherical surfaces.
3. The LED Lens itself belongs to precision optical components, so it requires extremely high precision in the mold, especially in the processing accuracy of the lens optical surface, which needs to reach 0.1 μ m. Lens bias needs to reach 3 degrees μ Within m. The processing of such high-precision molds generally requires the following equipment: ultra precision machining machines
4. The precision component of the mold lies in the optical core, which mainly uses specialized core steel to complete the initial embryo, nickel plating, and then uses an ultra precision machining machine to perform non spherical skill machining on the curved surface.
