Abstract
According to the characteristics of current COB package structural, as well as related research results, a novel COB package structure for LED module is proposed based on matrix free-form lenses and spray technology. By encapsulating matrix free-form lenses, the total reflection angle on the air-silicone interface is avoided and a specific light distribution is achieved. In order to achieve uniform illumination on the target surface, differential equations are created by Snell equation and the law of conservation of energy based on the intensity distribution of the light source. Numerical method is applied to solve the equations and 3D model is created from the calculated results. The structure is simulated by Tracepro. From the result of simulation, the uniform illumination on the target surface is achieved and the optical efficiency of the structure higher than 90%.关键词
