TYPICAL SPATIAL DISTRIBUTION
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.
