A simple method for determining the optimal operating point of an LED

Achieving optimal performance of an LED luminaire or LED backlight design requires numerous trade-offs. Understanding an LED’s power transfer characteristics empowers intelligent choices regarding cost, power consumption, and weight. While most LED datasheets publish pertinent data that can be used to make these decisions, data may not be formatted in a way that is readily applicable to the chosen application. Optimal performance requires finding pertinent information from manufacturer’s LED datasheets and utilizing methods to capture, reformat and analyze the data.
