THERMAL DESIGN
The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is
crucial for the end product to be designed in a manner that minimizes the thermal resistance from the solder point to
ambient in order to optimize lamp life and optical characteristics.
