3.5 Thermal design of LED-based luminaire
From the thermal design point of view, typical LED-based luminaire consists of an LED light source, a printed circuit board (PCB) and a cooling system. The LED light source incorporates semiconductor die (active part), optics, casing, and heat slug which is used to withdraw the heat away from the die. Heat slug is soldered to the PCB (mostly metal core PCB – MCPCB).
Figure 3.5.1 shows simplified setup of typical LED luminaire being simulated with basic input/output parameters.
