9 Thermal Measurements
The power supply assembly was installed into the lamp socket base and the
temperature of the LNK306DN SOURCE pin was measured, while the room ambient
temperature was 25 °C. The power supply was driving the three load LEDs (delivering
3 watts).
These results indicate that additional heatsinking may be required for example by
arranging the LED heatsink to contact the top of the SO-8C package of U1.
