In the daily use process of fluorescent lamp LED lamp holder, there is a very important parameter, that is its power. For this parameter, many friends are not very clear. Below, we can take a look at the introduction given by professional manufacturers, I believe you will be able to understand clearly.

The voltage and current of the fluorescent lamp LED lamp holder after rectification are not sine waves, and although the voltage before rectification is a sine wave, the current is not a sine wave. So the whole system is a non-linear system with screw caps. The original power factor is defined for a linear system, and the input and output voltage and current are required to be sinusoidal with the same frequency, otherwise Cosφ cannot be used. But in a non-sinusoidal system, since voltage and current are not sine waves, there is no phase angle that can be said. Therefore, the power factor in the nonlinear system must be defined from the beginning.
