Can led headlights melt plastic?
The temperature in the headlight mainly depends on the following aspects: the material and current of the bulb, the heat dissipation structure of the headlight housing, and the condensing radiation device in the lamp. Generally, the bulbs used in car headlights are halogen bulbs. The light bulb is ignited by electric current
If the base of the headlight is made of plastic, it is generally at 150 degrees, if it is steel, then there is no need to consider this issue.
Can led headlights melt plastic? What material is the lamp housing made of? If it is plastic, the phenolic plastic (bakelite) will not melt, but the carbonization temperature will be 400-500 degrees. The good thing is that ABS is softened at about 200 degrees and the melting temperature is above 300 degrees. The second use of recycled plastics, the surface finish is poor The kind; the softening temperature is also about 200 degrees. The melting temperature is between 200-400 degrees depending on the material. Others are also useful polyamines. The melting temperature of polyenes is 300-400 degrees. Polyamines will not melt but only carbonize temperature. Above 300 degrees. However, when the headlights are on, 80% of the heat is reflected to the outside (the reflective surface is good, and the lampshade is free of dirt). Don't worry about light bulbs that are not too powerful.
Temperature is related to heat dissipation. The LED itself can work at a very low temperature. Some high-power LEDs can often reach more than 100 degrees Celsius when working. However, high temperature has an impact on the life of the LED, so the lower the temperature, the better.
