Thermal grease (also known as heat paste, heat-conducting silicone, heat-conducting heat paste, wafer cooling paste) is a viscous fluid substance that is filled with incomplete flat and smooth surfaces between the components, which have a greater heat Conductivity, can effectively enhance the cooling effect of components.
LED thermal management:
LED is developed for lighting energy because of its high performance and significant energy saving potential.
Since the total amount of light generated by a single LED is much lower than that of other lighting sources, it is necessary to increase the forward current and the number of LED groups to increase the total output of light.
However, both of these solutions will increase the junction temperature and reduce the performance of LED.
As the operating temperature increases, the intensity of light decreases, the lifetime decreases, and the light color changes.
LED thermal management:
- Ambient air temperature
- Thermal path between LED and radiator
- LED performance
Sheen's thermal series products meet the key factors in the thermal path between the LED and the radiator
Using the correct heat sink can significantly reduce the junction temperature that has a profound effect on LED life
