Abstract: LEDs have about 75% of input energy, due to thermal losses, and therefore to increase the quantum yield of light devices, the presence of effective heat-removing constructions is necessary. The article deals with the materials, which are used to design printed circuit boards with high heat dissipation. Here are the results of modeling of the constructions based on Metal Core PCB (MCPCB) FR-4, polyimide and heat-conducting ceramic insulators.
Keywords: led, pcb, material, thermal conductivity
