Abstract	With the use of the capacitance, estimation techniques for the carrier concentration of the light-emitting diodes (LEDs) are introduced in this paper. The proposed model relates the carrier concentration to the forward current, the thermal resistance of the heatsink, the LED device, the device package, and the other physical parameters of the device (such as the bandgap energy, series resistance, and ideality factor), coefficients for the current, and temperature effect on the apparent capacitance altogether. It could provide a framework for analyzing LED devices. The estimation methods consist of simple procedures for electrical measurements, which are easy for LED device manufacturers and system designers to follow. The proposed model has been tested with LED devices, with reasonably good agreement between theoretical and practical results.
