XLAMP® XP-C LED
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.
