How do you get rid of the heat?
LED Heat dissipation principle: The heat dissipation to 3 modes: conduction, convection and radiation.
Conduction: the way of heat from the higher part of the object along the body to the lower part of the temperature;
Factors affecting heat transfer:
1. heat sink material
2. heat dissipation structure;
3. Shape and size of heat conducting material.
The closer the material sticks, the faster the heat transfer, and if the two materials only touch a little bit, the heat conduction will be blocked, and this is the thermal resistance. At this point, we can heat the material between the materials so that the heat passes well.
