Q:Does the LED street lamp need lightning protection?

Electrical appliances need lightning protection. The outer frame of the street lamp itself is equivalent to the lightning rod, as long as the inner line is insulated from the outer housing.

Q:Does the LED street lamp work well with a single light source or with integrated light sources?

Conditional words, of course, a single point is better, so that the light is not so obvious, and in tandem, bad 1, the whole string will not be bright

Q:LED street lamp warranty for several years, how long is the service life?

The price is more expensive, but the price is very high, customers are satisfied with the purchase

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

Import the IES file of lamp into DIALux software, and then set up the height, elevation angle, installation interval and so on

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:What are the types of LED street lights?

Gaoyou City long street lamps and lanterns factory, the production of various road lamp poles and high-power LED lamps.Rural generally consider using 20~50W between the line. Rural road width 3~5MI hope to cooperate with you in the street light project

Q:What is the maximum power of a LED street lamp at present?

If it is integrated, this power can be achieved.

Q:Road light is one of LED. How much is it?

The price of street lamp should be based on the caliber, height, wall thickness, shape of lamp, power source of light source and choice of chip driver.

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

The life of LED street lights is much higher than that of high pressure sodium lamps, which are generally replaced by LEDLuminous flux comparison, it must be high sodium light, but the light efficiency of sodium lamp utilization is not high, many light is invalid, but also poor color rendering, LED generally do white light, see clearly, bright

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

The reason is simple, because the current increases, the power of the lamp increases greatly, but the relative luminous flux increases not in proportion. That is, power increases faster than light flux increases. So if you increase the current, the light will decrease. But the brightness will increase.
