Abstract

The variation of high-power LEDs in performance from manufacturer to manufacturer. However, Information provided may not be sufficient in determining concise switching properties of these LEDs at certain biased mode. This has caused switching problems and performance limitations depending on the manufacture type. This paper demonstrates the rising and falling edge transient effects for a number of different LEDs using MATLAB CAD tool. By biasing these LEDs with external clock pulse, effects such as exponential decay were observed at some pulse edges as output. Therefore, highlights via experiment of the problems seen in edge transients and proposition as to why they occur were documented in this paper.
