WebAug 2, 2024 · The material of the lens is assumed to be PMMA (Polymethyl Methacrylate) with a refractive index of n = 1.49. It is assumed that the LED light source emits 100 lm light energy and 1.0 million rays were used for simulation. The lighting unit is 5 m away from the target surface. 3.1. Design with Ideal Lambertian LED Although LEDs are far more efficient than incandescent lamps in terms of lumens emitted per watt supplied, the emitters can only handle a small number of watts. As a result, LED lumens must be carefully managed to reach their intended target. The optical components comprise an important part of the overall … See more There is no single metric that can fully describe the optical performance of a given lens. To specify an optimal lens for a given application, lighting designers need … See more Ensuring the lens is optimally sized in relation to the LED also has an important bearing on performance.
