Thermal effects in LED arrays were investigated as a function of LED power, size, and spacing. For high power LEDs, the increase injunction temperature due to a high driving current plays an important role in LED performance, e.g. conversion efficiency, optical degradation, etc. Since the maximum driving power that determines LED brightness is limited by the critical junction temperature, thermal influence from adjacent LEDs in an array has to be also taken into account carefully. The relationship between maximum allowed driving power and LED BLU design parameters are discussed along with other factors to be concerned.
