摘要: (LEDs) to improve both the heat dissipation and substrate light-absorbing problems encountered in conventional A1GaInP/ GaAs LED samples. Especially, this LED samples can be accomplished without additional dicing process. It was found that the peak-spectral wavelength of the AlGaInP LED with an electroplated copper substrate exhibited only about 3 nm shift at 400mA, corresponding to a similar to30degreesC rising in the junction temperature. However, the junction temperature increased to 110degreesC easily for the AlGaInP/GaAs LED sample under a current injection of 400 mA. This indicates that the joule heating is less pronounced for the high-power AlGaInP/mirror/Cu LED sample where the metallic substrate provides a good heat sink.
