What is the reason for the low power factor of LED street lamp?
What you said is not too clear, the general LED is to drive the switching power supply, switching power supply method of improving power factor is to increase the power factor correction circuit, power factor correction circuit is more than 50W, can play a role. The LED street light power is generally more than 100W, if the power factor is low, it can only show that its driving power supply, there is no power factor correction, or is not done well. Well done, it should be more than 0.95There is no power correction circuit for the driving power of the first paragraph
