Traditionally, approximate Lambertian models are widely used in designing the light-emitting diodes (LED) arrays in spite of their errors compared with the experimental data. But now a novel LED optical model for uniform illumination system has been proposed, in which the curvefitting technique is used to reduce the inherited errors and modify those previous models. The points from the curve of the LED light intensit... Hits: 4694 Download times: 253 View Full Text    Download reader
