Computer modeling of transient processes in LED modules

Abstract

In this paper, a theoretical analysis and a practical study of the transient processes occurring when the LED modules are switched on are carried out. Light-emitting diode (LED) modules are a parallel, serial or mixed connection of individual light-emitting diodes in a discrete or integrated design. The non-uniformity of the voltage drop at the moment of switching on series-connected LEDs or series-connected LED cells containing parallel-connected LEDs is shown. This may be the reason for a short-term electrical breakdown of their p-n junctions. The obtained results can be useful for predicting the durability and reliability of LED devices.
