Thermal analysis of the LED-heatsink system.

Calculation thermal resistance of heatsink. Selection of parameters of the components of the system:
- LEDs,
- material of PCB (MCPCB),
- thermal interface material (TIM).

Our goal is to accelerate the process of pre-calculation of the thermal system LED-heatsink.
