[0002] With the development of science and technology, the application of LED lamp is more and more extensive. The main performance of current LED lamp includes luminous characteristic, electrical characteristic, heat dissipation characteristic etc. Among them, the luminous characteristic is influenced by the electrical characteristic of LED lamp, that is, the power component and rectification component in driving circuit. Good driving circuit setting can not only reduce the frequency flicker when LED lamp is used, ensure the stability of LED lamp light emission, but also reduce the heat dissipation of LED lamp, prolong the service life of LED lamp.

[0003] In the working process of LED, 10% to 20% of electric energy is converted into light energy, and the rest is converted into heat energy. Therefore, heat dissipation is one of the key problems restricting the wide application of LED.

If the heat gathered in the lamp body of LED lamp cannot be discharged in time, the working performance of the above power component and rectification component will be affected. Therefore, heat dissipation is one of the key problems restricting the wide application of LED. Based on this, the case is born. CONTENT OF THE UTILITY MODEL
