中文摘要：
以自主研发的一体化封装LED为模型,使用光学模拟软件TracePro对该模型的配光进行仿真。为了优化该模型的光强分布及出光率,对比分析了不同反光杯张角及透镜形状对LED配光性能的影响。仿真结果表明：反光杯张角及透镜形状对LED的光强分布及出光率均有较强影响。45°反光杯张角有着较好的光强分布。添加透镜可以提高出光率,扁平透镜可以达到较高的出光率。45°反光杯张角加半球形透镜在光强分布与出光率上取得均衡。
英文摘要：
Using the optical software TracePro,the light distribution of our self-developed integration package of LED is simulated.In order to optimize the light distribution and extraction of the model,the different shapes of lens and inclination of reflectors were analyzed.The results of simulation show that there is a strong impact on light distribution with different lens and reflectors.There is an uniform light distribution with the 45° reflector.The light extraction will be improved by lens,meanwhile the flat lens can achieve a higher light extraction.The 45° reflector with hemispherical lens can achieve a balance between light distribution and extraction.
