Q:How much solar panels do you need to make a 15W LED solar street lamp?

According to your work time and the continuous rainy days, and then calculate the power: LED * * working time of continuous rainy days = depth of discharge battery (AH) battery discharge depth / sunshine time / silicon solar panel power = charging efficiency

Q:How to detect the leakage of LED street lamp poles?

You can use a multimeter, remember to clear it first. Cut to the voltage of the gear, and then one end of the ground, one end of the lamp pole (to measure the exposed part of the metal), to see whether the pointer or digital data to the amount to know; there is a volume to the data, there is leakage.

Q:How is the minimum illuminance of LED street lights Emin obtained? How to calculate?

If you want to measure the value, I can only say that the approximate, because the illuminance value on a point value, the actual measurement is the target area is divided into small areas of uniform, center to measure each region with the value of the measured value, there is a minimum value.

Q:What are the main uses of LED street lamps?

Street lights must be used on highways, such as roads, highways, urban roads, parks and so on

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

If the power is the same, the brightness of the white and warm white light should be the same.

Q:What is the reason that the longer the wire pulls on the LED street lamp, the lower the voltage?

Wires have resistances. The longer the wires or wires, the smaller the resistance, the greater the resistance.

Q:400W high pressure sodium lamp can replace 150WLED lamp? Luminous flux?

Yes, and under the current technical conditions, the life expectancy of HPS is much longer than that of LED street lamps

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

LED has higher light efficiency, and can reduce the power configuration properly. It can be selected in the 50%-80% of the sodium lamp as appropriate

Q:The power consumption of a street lamp?

A power rating of 200 watts of street light, operating at rated voltage 500 hours of power consumption
