What are the performance requirements for LED heat dissipation substrate materials?

The LED heat dissipation substrate is a heat dissipation part used in LED lamps, and its performance requirements mainly include thermal conductivity, electrical insulation, mechanical strength and processability.


The LED heat dissipation substrate is a heat dissipation part used in LED lamps, and its performance requirements mainly include thermal conductivity, electrical insulation, mechanical strength and processability.

First of all, thermal conductivity is one of the important performance indicators of LED heat dissipation substrate. Due to the high working temperature of the LED, it is necessary to quickly conduct heat out through the heat dissipation substrate to ensure the working stability and life of the LED. Therefore, the heat-dissipating substrate has a high thermal conductivity and can efficiently conduct heat to the heat sink or the external environment.

Secondly, the LED heat dissipation substrate needs to have good electrical insulation performance. Since LED lamps need to be connected to the circuit, the heat dissipation substrate must have good electrical insulation performance to prevent safety problems such as short circuit or electric shock caused by current passing through.

In addition, the LED heat dissipation substrate also needs to have high mechanical strength. In the installation process, the heat dissipation substrate needs to bear a certain pressure and pressing force, so it needs to have sufficient mechanical strength to prevent deformation or cracking.

Finally, the processability of the LED heat dissipation substrate is also an important performance indicator. Due to the different shapes and sizes of LED lamps, the heat dissipation substrate needs to be cut, punched, bent and other processing according to actual needs, so as to facilitate the assembly and installation of the lamps.

In summary, the performance requirements of the LED heat dissipation substrate material include thermal conductivity, electrical insulation, mechanical strength and processability. These performance indicators will directly affect the heat dissipation effect, safety and reliability of LED lamps. Therefore, when selecting the heat dissipation substrate material, it is necessary to comprehensively consider these performance indicators according to the specific application requirements to ensure the performance and life of the LED lamp.
