Electrical Characteristics (T
Thermal Design
The maximum forward current is determined
by the thermal resistance between the LED
junction and ambient. Given an existing
thermal resistance of 12°C/W between the
junction and the solder point, 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.
