Background technique

LED bulb lamp is a new type of energy-saving lamp that replaces traditional incandescent lamps. It is superior to traditional lighting products in terms of luminous principle, energy saving and environmental protection. With the rapid development of LED lighting technology, the energy-saving effect of LED bulb lamps has reached a very high level.

It is the general trend for products to replace traditional lighting products.

In recent years, LED research and development, production and application have developed rapidly. A lot of practice shows that the basic reason why the LED cannot increase the input power is that the LED will emit a lot of heat during the working process, which will cause the junction temperature of the tube core to rise rapidly. The higher the input power, the greater the heating effect, and the increase in temperature will cause Changes and attenuation of device performance until failure.

According to the principle and basic method of heat transfer, there are three main methods of heat transfer: conduction, convection, and radiation. The traditional LED heat sink conducts heat through the heat dissipation fins. This method has poor heat dissipation effect, which leads to an increase in product temperature and affects the service life. .
