LED is a light-emitting diode (Light Emitting Diode), which is a common electronic device that emits energy through the recombination of electrons and holes.

Energy saving is the most prominent feature of LED lamps. Its energy consumption is one-tenth that of incandescent lamps and one-fourth of that of energy-saving lamps. The service life of LED lamps is as long as 10 years or 40,000 hours. In fact, the problem lies in the heat dissipation capacity of LED lamps. Although the life expectancy of the light-emitting device of the LED lamp is very long, the performance of the lamp holder and the heat dissipation design of the circuit board is uneven.

In order to convert alternating current into direct current, the circuit board of the LED lamp needs to be equipped with an electrolytic capacitor, which has a structure similar to a battery and is therefore prone to failure at high temperatures.

Especially for bulb-type LEDs, heat is more likely to accumulate in socket parts, causing malfunctions. Even though the LED itself has a long life, if the board part fails, it won't power up and it won't emit light.

There is an interesting phenomenon in the heat dissipation of China LED outdoor luminaires. If the temperature of the heat sink of the LED lamp is not high, it does not mean that the heat dissipation is well controlled, because it may be that the internal heat is not conducted out. If the temperature of the heat sink of the LED lamp is high, it should not be taken lightly, because the internal temperature of the LED lamp may be higher at this time.

Heat dissipation has become a big problem affecting the selection and use of LED lamps. As a solution, it is best to choose LED lamps with heat resistance. Although this will further increase the cost, it can guarantee a long service life and achieve cost sharing. In the long run, the cost will be lower than using ordinary lamps. Or LED lamps without heat resistance.
