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 intensity are adopted, and a spline curve is designed for fitting, which obtains the revised mode. To verify its feasibility, we apply the new model in a 4×4 array design. The results show that compared with the approximate Lambertian, the light intensity distribution produced by the fitting model is more uniform and intense, as is expected.展开更多

文摘Optical models directly effect the irradiance distribution of observed surface. 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 intensity are adopted, and a spline curve is designed for fitting, which obtains the revised mode. To verify its feasibility, we apply the new model in a 4×4 array design. The results show that compared with the approximate Lambertian, the light intensity distribution produced by the fitting model is more uniform and intense, as is expected.
