If you have known the MCPCB design process, you may understand LED product manufacturing very very easy.
Because the designing way is the same, the Primitive purpose is decrease the temperature.
With only three components, LED, MCPCB and heat sink, the thermal design of an LED system should be straightforward.
Low Thermal Resistance is very important to MCPCB design
Three part components were not just assembly to together, MCPCB design companies must consider MCPCB low thermal resistance.
All it requires is that the pathway has low thermal resistance.
In theory this can be accomplished by selecting materials with high thermal conductivity and is, indeed, one of the reasons why most heat sinks are made of aluminium.
MCPCB thermal resistance and Thermal conductivity
Thermal conductivity, which has units of W/MK, is a simple material constant that refers to the ability to transfer heat by conduction with a high number being preferable.
