Someone might tell you that LEDs do not give off heat. It is not really true.
Generally, all light sources produce heat, LEDs are no exception. You can say that there is no heat in the beam but for LED device itself, does generate heat, it just not emit as much heat as other sources of light.
An efficient-designed LED system, 95% of the energy is converted into light and only 5% is wasted as heat. Prolonged heat affects LED’s light output and shorten the useful life of many LED systems. In general, the cooler the environment, the higher efficient an LED’s will be. Obviously, control the temperature of an LED is one of the most important aspects of optimum performance of LEDs. Thus most LED manufacturers are striving to get unique heat sink material to absorb greatly the heat produced by the LED and dissipate it into the surrounding environment to make LED products perform as successfully as expectation.
Perhaps, you are going to invest in an LED automotive fixture for your car recently, this simple tip might help you to get a suitable efficient LED products.
