How about the high pole lighting radius 40m
- The rod body is generally cylindrical single structure, steel plate rolled, height of 25-40 meters to 25 meters above the new lighting device 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 and the surrounding environment, and specific lighting needs; inside the lamp by the light and light source, generally uses the high pressure sodium lamp and metal halide lamp. Lighting, radius of 60 meters. The rod body is generally cylindrical single structure, steel plate rolled, the height is 15-40 meters.s
To achieve the following functions of LED lights, what knowledge do you need to use?
- On the LED lamp lamp not appropriate. Pole 35 meters, the height is very high, or install lamp, yellow 1000W, yellow light through fog and strong, suitable for wharf, airport, border and other places need light and strong.s

- More than enough, we're producing LEDs
What is in the lamppost of the LED street light?
- 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.s
How much illumination can the 200 Watt LED projector reach 30 meters?
- Generally speaking, LED light projection angle 120~180 degrees, 200W LED lamp in the 30 meters position, the projection area in the ground should be about more than 100 square meters, the higher the lumen of the light, the more bright the ground. Perhaps this involves some calculations and the specifications of the lamp itself.s
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.s
What's on the lamppost of the LED street light? What is the function?
- LED street lamp poles are: cross flow source, the role of the current stability, so that the light effect to achieve a stable effect, as well as variable pressure.s
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 lampss
