What happens to the LED street light source?

At present, LED street lamps have been widely used, and now more and more roads advocate the replacement of traditional incandescent lamps and high-pressure sodium lamps with LED street lighting. However, the weather in summer is hot year by year, and LED street lights always face the test of high temperature heat dissipation. What if the LED street light source does not heat well?

 

1, life expectancy is reduced

For LED street lights, heat dissipation is a top priority. If the heat is not good, it will have a series of adverse effects on the use of street lamps. For example, an LED light source converts electrical energy into a light source, but not all electrical energy can be converted into a light source, which is subject to a conservation law. If it is extra power, it may be converted into heat.

If the LED heat dissipation structure is not designed properly, it will not be able to quickly eliminate excess heat, which will cause a large amount of heat to the LED street lamp, resulting in a shortened life of the LED street lamp.

2. Material quality is declining

If the LED street light source is overheated and cannot remove the heat, these materials will be repeatedly subjected to high temperature oxidation, resulting in a decline in the quality of the LED light source.

3, electronic device failure

The temperature of the LED street light source gradually rises, and the greater the resistance, the more current will be generated, so that more and more heat will be generated. As a result, the LED light source will cause electrons due to overheating. The component is damaged, resulting in a malfunction.

4, the deformation of the luminaire material

In fact, we will encounter many such things in life. For example, when an item encounters too hot temperature, it will appear slightly deformed, and the LED street light source is the same.

There are many materials composed of LED light sources. When the temperature rises, the size of thermal expansion and contraction of each part will be different, so it is possible to cause the spacing between the two original parts to be too small, and then squeeze each other to cause deformation and damage.

LED street light source is still very necessary to dissipate heat. In the future, the technology of LED light source heat dissipation will be more mature, so that LED lamps can get rid of the trouble of heat dissipation.
