摘要	The principle of self-heating effect of AlGaInP micro-LED cells was analyzed. By analyzing the temperature distribution of each cell with square-circle electrode, the relationships of the internal quantum efficiency vs. anode current and the lattice device temperature vs. anode voltage were got. Under 2.2 V driving voltage, the thermal impedance of each layer was calculated and the effective thermal impedance was obtained as 96.7C/W. After adding heat-sink to the device, the thermal impedance of the device with heat-sink structure was as low as 30.6C/W in ideal condition. The results show that the thermal performance can be improved obviously with the designed heat-sink structure.
