Q:What is the difference between the brightness and illuminance of LED street lights and the brightness and illumination of ordinary high-pressure sodium lamps?

There are differences, LED lights brightness and illumination will be greater, Zhongshan Ming inter lighting is specializing in the production of lightsAnd other outdoor lamps.

Q:Is there any national standard for surface coating of LED street lamp?

Yes, there is no specific standard in our country at present, as long as you can wear the standard of corrosion prevention!

Q:Please use LED lamp beads with other lamp beads is not the same?

It is nonsense, misleading, the landlord said principle two lights are the same, just as there is a single lamp, open circuit protection, but can not reverse voltage higher than the manufacturer's logo. For street lights, open circuit protection is integrated into the drive circuit,

Q:How high should the installation height of the LED street lamp be?

In order to avoid glare, you can choose the f (d) (E), the installation height of street lights should not be less than 4.5m. The distance between the poles of the street lamp can be 25 to 30m, and the distance between the lamp posts entering the curve should be reduced appropriately.

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:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program

If there are 10 or so parallel units. Each unit of parallel =0.18x60=10.8KW, 16mm - 25mm - copper or aluminum wire. Light controlled single-phase AC contactor 100A.

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:How can a LED street lamp protect against lightning strikes?

One is the external lightning protection system, and the other is the internal lightning protection system, which complement each other and complement each other.

Q:LED good or low frequency electrodeless lamp?

There are three reasons why the Lantern Festival should be replaced by LEDA: making LED material is more expensive, not very environmentally friendlyTwo: LED decay is serious, that is to say after a period of time to reach a brightness brightness beforeThree: LED heat dissipation is not goodThese three points will cause LED to be replaced

Q:Why is the higher the current, the lower the light efficiency?

Because the higher the current, according to Ohm's law, of course, the power will also increase, while the luminous efficiency is the total luminous flux / total power
