Q:How many watts are the street lights?

Power ranging from fifty to several thousand, as well as mercury vapor lamps, sodium lamps, LED lights and the like

Q:Led streetlights power down half, through what?

In order to save the power consumption, LED street lamps design the power of the first half of the night and the latter half of the night power, and the power drop of the LED street lamp is realized by the controller,

Q:What should I pay attention to when buying street lamps?

Attention should be paid to the service life of LED street lamps. LED lamp life is relatively long, but affected by environmental factors such as light, LED lamp, life is affected, in the purchase of LED Street must understand clearly marked by the light LED lamp manufacturers and service life, good quality, light small, relatively long, the price will be high.

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:How much is the price of the LED street lamp?

Tens to hundreds of dollars range, this depends on what you focus on the LED street lights? Guoqiang photoelectric cost-effective lamps

Q:LED lamp with air leakage to help the thunder?

There is no air leakage with LED lights for the role of lightning protection. The function of the switch of leakage air breaker is to work by current. To enable the street circuit with lightning protection function, must use a surge protector, installation and circuit breaker in parallel. It works by limiting the overvoltage and cutting off the circuit as long as the voltage exceeds the set point to protect the electrical equipment.

Q:Why solar energy centralized power supply street lamp must be supplied by AC LED lamp?

1: DC transmission distance is limited, the pressure drop is very high2: DC voltage - protection switch, controller parts and other technologies immature or cost slightly higher3: DC wiring voltage is not very high, but the street lamp power is not small, the current will be very high, the cable cost

Q:Why does fog cause fog when the LED street lamp is aging?

Specializing in the production of outdoor lighting facilities and all kinds of street lamps, LED lights, is the production of outdoor lighting and sales of high-quality outdoor lighting, street lamps and engineering facilities of professional manufacturers. Main production: landscape lamp, lamp, road lights, garden lights, LED lights, solar lights, LED lights, lawn lamp, underground lamp, electrodeless lamp, lifting lamp, lighting engineering, and related accessories business.

Q:The power supply of LED street lamp has no influence on the grounding power. The possibility that the power supply will burn out is not big enough

The ungrounded words are easy to produce static electricity is not good for the lamp and IC.

Q:Features of LED street lamps

LED street lamp is different from conventional, LED light source adopts low voltage DC power supply, by the high white GaN based blue LED and yellow synthesis, has the advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in the road. Cover can be made, high temperature up to 135 degrees, low temperature resistance up to -45 degrees. 1, the characteristics of its own - one-way light, without the proliferation of light, to ensure the efficiency of light.
