In this thesis, two innovative driving modes are proposed to improve the thermal effect when turning on LEDs. The traditional driving mode will induce two shortcomings. The first one is the initial state with radiant power drop dramatically, and make the light maintenance is above 0.98. The second one is driving with heat accumulating state which leads to low efficiency, and the enhancement of optical power can up to 7.5%. The innovative driving mode can conquer the obstacle which traditional driving modes have. With the driving mode, the efficiency of LEDs can perform better and the emitting property can be more stable.
