Today, I would like to share with you the influence of LED lamps on the heat dissipation of lamps. The main points are as follows:
1, The most direct impact-poor heat dissipation directly lead to reduced service life of LED lamps
Since LED lamps convert electric energy into visible light, there is a conversion problem, which cannot convert 100% of electric energy into light energy. According to the law of energy conservation, excess electric energy is converted into heat energy. If the heat dissipation structure design of LED lamps is not reasonable, this part of heat energy can not be eliminated quickly. Then due to the small size of LED packaging, LED lamps will accumulate a lot of heat energy, resulting in reduced life.
2, cause material quality decline
Usually electronic equipment used for a long time, part of the material will be easy to oxidize. As the temperature of LED lamps rises, these materials are repeatedly oxidized at high temperature, which will cause the quality decline, and the life be shortened. At the same time, because of the switch, the lamp caused many thermal expansion and cold contraction, so that the strength of the material was destroyed.
3, overheating causes the failure of electronic devices
This is a common problem of semiconductor heat source, when the LED temperature rises, the electrical impedance increases, resulting in an increase in current, increasing current leads to the rising heat , so reciprocating cycle, more heat will be caused, will eventually cause electronic components overheating and damage, causing the electronic failure.
4. The material of lamps and lanterns is deformed due to overheating
LED lamps are composed of a number of parts, different parts of which are made of different materials. The size of these materials is different from that of thermal expansion and cold contraction. When the temperature rises, some materials will expand and bend because of overheating. If the space between adjacent parts is too small, the two can squeeze, which can damage the parts in serious cases.
The poor heat dissipation of LED lamps will produce so many problems. The problems of these components will lead to the decline of the performance of the entire LED lamps and shorten their life. Therefore, LED heat dissipation technology is an important technical problem. In the future, while improving LED energy conversion rate, LED heat dissipation structure should be designed more effectively, so that LED lighting lamps could get rid of the trouble of heat dissipation.
