Is It Normal for Car LED Lights to Get Very Hot When in Use?

[McReese]

If the temperature exceeds 60 degrees Celsius, it is abnormal and indicates a heat dissipation issue. Below this temperature, it is considered normal. Introduction to the Heating Principle of Car LED Lights: Car LED lights use light-emitting diodes as the light source. During operation, only 25% of the electrical energy is converted into light energy, while the remaining electrical energy is entirely transformed into heat energy. When accumulated in an enclosed space, the heat builds up, causing the LED lights to become increasingly hot. Therefore, car LED lights must be used in conjunction with heat dissipation devices. Causes and Solutions for Overheating of Car LED Lights: If an infrared thermometer detects that the temperature of the headlight cover exceeds 60 degrees, it indicates that the LED lights are overheating due to poor heat dissipation in the lighting system. This issue can be resolved by spraying nano-radiation coating on the surface of the light body to enhance its heat radiation capability or by installing additional fans.
