Q:What's the reason why the LED street lights don't work?

The LED lamp power is waterproof power, bad to change new power protection function is not perfect, directly affect the quality of fault phenomenon LED lamp 2, bad part there are several possibilities: 1), such as LED lighting power supply for multi-channel constant output, which may be a group of bad, 2) is LED chip is not good, or is the LED lamp cooling caused by bad burn LED chip.

Q:How to determine the power of LED street light?

It is difficult to determine the power of the LED street lights used on a particular section of the road, but it can be estimated from the street lights seen

Q:Does the LED street lamp 80W or 100W need to be compensated by a single light capacitor?

Capacitor compensation is reactive power compensation or power factor compensation. The power system of electric equipment in use will produce reactive power, and is usually inductive, it will make use of the capacity of power efficiency, and by increasing the capacitance of the way properly in the system can be improved.

Q:Do ballast ballasts need to be used for starting the LED street lamp?

LED requirements are constant current power supply, some can also use switching power supply, but the cost is relatively high

Q:What are the advantages of LED road lights?

Safe and reliable, long service life. Low calorific value, no heat radiation, cold photoelectric, safe touch, precise control of light type and luminous angle, light and soft color. The average life span is 50 thousand hours. The service life of the LED lamp can be more than 8 years, and the maintenance cost of the lamp can be greatly reduced, and the frequent change of the lamp is avoided.

Q:How big wires should fifteen LED street lights require?

Yes, you need to know what the power value is for each or 15 street lights

Q:Who knows LED street lamp warm white light and positive white light have what difference, how should choose?

Because the light intensity of the human eye light is higher than that of the warm white light, the naked eye will feel that the white light is brighter than the warm white one.

Q:How to calculate the radiation area of solar LED street lamp

The LED lamp has not been able to present the luminaire's illumination curve so that the LED lamp can not be used in industry at large. It is said that LED is at a slightly far distance, and its illumination is greatly decreased.

Q:What is the LED lamp light?

LED (Light, Emitting, Diode) light emitting diode is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.

Q:Solar street lamp, 60 watt LED lamp holder, with large battery

Total lighting time per night (temporarily indicated by H);60W the lamp cap is divided by the battery's rated voltage to draw the current (temporarily indicated by A)The number of days required for continuous wet days (temporarily indicated by T);Battery to prevent overcharge and over discharge, generally charged to 90%, discharge more than 20%, take 70% calculation, formula for:Battery capacity = 70% (A*H*T).
