1. Keeping LEDs Cool Gets More Manageable Through Simulation
LEDs require careful temperature regulation which is accomplished by a heat sink; use simulation to control costs, size and shape of the heat sink
Using a 3D model, electrothermal analyses predict self-heating, current crowding and forward voltage – performance indicators of LEDs

The 3D geometry of the LED lighting device is composed of an internal LED module, a heat sink and a cap.
Simulation results of air domain inside the cap shows temperature variations.
