FAQ

How is the rated current of the LED street lamp holder?

The rated power of the lamp cap is divided by the input voltage and then divided by the power factor.

Do you think it is expensive to install LED street lamp with WIFI function?

The cost will be much higher, and it will involve control and network problems.

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

Excuse me, LED experts. How many watts do LED street lights usually have on the roads?

Choose different power or combinations according to the width of the road, the density of the street lights and the required illuminance

How many watts are the street lights?

This comes from the needs of the road. Generally 8 meters below the design of the use of 250W or so street lights, more than 8 meters designed to use 400W high-pressure sodium lamp.

LED technical requirement of street lamp 100W

(5) the environmental temperature of LED street lamp should be -20 to +50 centigrade, and other special requirements such as temperature, humidity and corrosiveness of the local environment should be satisfied.(6) the power factor is greater than or equal to LED 0.95 lamps, lamp power supply efficiency is more than 95%.(7) the working voltage range of LED street lamp is from 85V to 265V (in this voltage range, LED lamps can still work normally).(8) LED street lamp has surge suppression performance (against lightning stroke), the input over-voltage protection, when the voltage is restored to normal, can resume work.
