What is the driving principle of led incandescent lamp?

LED (Light Emitting Diode) is a semiconductor light emitting diode. It is made of a semiconductor with a p-n structure. When current flows through the p-n structure, electrons and holes meet and combine at the opposite positions of the p-n structure, releasing light energy. This principle of luminescence is called electron-hole relativity.

The driving principle of LED incandescent lamp is to convert DC power into high-frequency AC power, and then convert AC power into DC power through the rectifier circuit of LED incandescent lamp. This can effectively reduce the thermal effect of LED incandescent lamp and prolong its service life. It is also necessary to use current limiting elements in the driving circuit to ensure that the LED incandescent lamp works in the best state.
