FAQ

Pole 25 meters high, 100 meters in diameter required W
You have to use the 250W light. 8-10, see what you choose lamp plate.
Why high pole lamp control switch to the specified time to advance light
Is the old lamp light source lamp, unlike the current LED light power immediately lights, lamp needs time to preheat, light up slowly, so need to ensure optimal brightness light requirements in time.
How to select suitable driving power for LED street lamp
LED street lamp driver. Working outdoors, poor environment, the temperature variation of four seasons a year, the summer sun, winter cold, but also accept the rainstorm, lightning shock, so all kinds of tolerance need to be considered.
How about the high pole lighting radius 40m
Lamp: generally refers to a new type of lighting device more than 15 meters of steel column type lamp and high power combined lamp frame. It is composed of a lamp holder, lamp, electric rod and base parts. Head shape according to user requirements, the surrounding environment, and specific lighting needs; inside the lamp by floodlights and cast light lamps, lamp using NG400 high pressure sodium lamp, lighting the radius of 60 meters.
What's in the lamppost of the LED street light? What is the function?
LED street lamp has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp will be the best choice for energy saving reconstruction.
What's in the lamppost of the LED street light? What is the function?
Light emitting diodes (LightEmittingDiode, abbreviated as LED) is a semiconductor pn junction formed with weak electricity can light high efficiency solid-state light source based on the forward bias voltage and the injected current, injected into the P region of the hole and injected into the N region electron in diffusion into the active region after radiation and emit a photon, electric can be directly converted into light energy.
LED lamp configuration with traditional lamp compared advantage?
There is not a kind of ah, LED energy saving, environmental protection, small decline. Good but generally high pole lamp lumens, with lamp and light, do you want to compare LED and sodium lamp? LED has a relatively long life, about two times that of sodium lamps
