Abstract

Monitoring the thermal regime of the high power LEDs used in lighting applications and in optical communications is nowadays a must. The paper presents our studies and experimental results concerning the transient, continuous and pulsed regimes of high power LEDs, based on a method for temperature measurement that makes use of the protection diode embedded in the LED package. The method proved to be consistent with the exponential law describing the transient regime and with the mathematical relation between continuous and pulsed regimes, qualifying thus as a potential monitoring tool for LED-based systems.
