Abstract: High-power high-brightness light-emitting diode (LED) for its energy-saving,environmental protection, long life and other outstanding performance penetrate gradually into modern lighting. LED experts predict that half of the 21st century LED lighting will be gradually developed as the main products of the power light. However, LED lighting is still facing several big challenges: light-emitting efficiency, color rendering index, structure of thermal and so on.
High temperature on the LED light-emitting enormous impact on the quality and service life, from the design that prevent the overheating is the most challenging tasks. Therefore, the use of computer-aided analysis combined with experimental methods to simulate the working performance of LED lump becomes increasingly important.
