Abstract: In many investigations on LEDs, the radiant power-current characteristic of LED has been drawing for high currents without giving any mathematical equation between them. The radiant power-current variation of LED can be expressed with a formula. In this study the thermal effect on radiant power of LED at pulsed high currents has been formulated and a mathematical equation has been derived between current amplitude and radiant power of LED. This equation has been examined by drawing theoretical and experimental variations on the same graph. In addition, the effect of instantaneous resistance-current variation of LED on its radiant power-current characteristic has been shown.
