Abstract

The subject of the paper is focused on novel utilization of super-efficient light-emitting diodes (LEDs) as measuring sources of optical radiation when the determined current pulses are used to drive them. The relationships between input electrical pulse parameters, such as the amplitude and duty factor, and output optical power are studied. Results of LEDs dynamics analysis and experiments made on representative elements are reported. An especially designed generator was used to obtain standard rectangular current pulses needed to evaluate LEDs optical responses.
