Abstract
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.
