Led fluorescent tubes have two important parameters. Careful friends, you should know to know:
1. Power factor (PF): The power factor is the cosine of the phase difference between voltage and current. Because both current and voltage are wave patterns, one is a sinogram and the other is a cosine diagram; since the two waveforms differ by 1/4 cycle (ie: 90 degrees), a PF value is formed, in order to increase the PF value, A correction circuit is added to the power supply, so the power cost of the PF value is relatively high. The PF value without the PF correction circuit is generally around 0.6, and the basic PF circuit can reach about 0.9 or even higher.
When the PF value is low, it will pollute the power grid of the entire power supply system. When the PF value is low, the utilization rate of the power generation equipment to the power grid becomes lower. Therefore, the state has PF value requirements for some power-intensive equipment. There is no clear requirement for 50W or less. The national requirement is that the PF value is greater than 0.6.
2, conversion efficiency: popular speaking is the ratio of output power and input power, for example: 10W of electric power is consumed by a lamp, but only 8W of electric power is used to illuminate (also called: useful work), also With 2W of electric power, the heat is lost on the power supply device (also called: no work), then the power conversion efficiency of this lamp is 80%.
