Electrical Characteristics (T
Thermal Design
The maximum forward current is determined by the thermal re-
sistance 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.
