Silicone wires are widely used in LED lighting fixtures, and some friends will be confused at this time. Why do you need silicone wires for LED as a cold light source?
Silicone wires are widely used in LED lighting fixtures, and some friends will be confused at this time. Why do you need silicone wires for LED as a cold light source?
This is actually related to the energy conversion of the LED. The reason why the LED heats up is that the applied energy is not fully converted to light energy, but partly to heat energy.The indicator light is only 100lm/W, and the electro-optical conversion efficiency is about 20% to 30%.That is, about 70 percent of electricity is converted to heat.This heat, if not dissipated for a long time, will keep the temperature high.Therefore, ordinary LEDs are equipped with radiators, although the radiator can prevent excessive temperature, but the overall use temperature is still a high level for a long time, when the life of ordinary PVC electronic wires will be significantly shortened or not usable, it must be replaced with silicone wires.
The advantages of silicone wires, or silicone high-temperature wires, over ordinary PVC electronic wires are mainly reflected in the temperature resistance. Silicone wires can withstand low temperatures down to 60 degrees and high temperatures up to 200 degrees.Normal PVC electronic wires are generally kept at a low temperature of zero and at a high temperature of up to 70 degrees.In addition, the silicone wire has some flame retardant, radiation resistance, aging resistance, ozone resistance, water proof and other characteristics. It is softer than ordinary PVC wire and is flexible.
