Q:Pole 25 meters high, 100 meters in diameter required W

Single disc high pressure sodium lamp 12*400 watts or LED12*200 watts can

Q: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.

Q:Why high pole lamp control switch to the specified time to advance light

Should be the time control switch failure, it is recommended to ask manufacturers to deal with.

Q:How to select suitable driving power for LED street lamp

The power of the driving power is left with the proper allowance and the hard quality is required.

Q:How much is a minimum price of 20 meters high pole lamp? How much is the general price?

Hello, just said that LED as long as 2500 yuan, is not in line with the current market, belongs to defective products.Our LED lamp 240W price of 3600 yuan / lampAs for high-pressure sodium lamp, the whole lamp is not 200 yuan, the price is about 800 yuan.

Q:What's in the lamppost of the LED street light? What is the function?

LED street lamp with the conventional high-pressure sodium street lamp is different, the light source of high power LED lamp with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in city road lighting. The outer cover can be made of PC tube, with a high temperature resistance of 135 degrees. Low temperature resistance up to -45 degrees

Q: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.

Q:35m lamp (18 light 2) to put much LED light? To meet the diameter of 200M

The white light projection lamp 1000W is suitable for being installed in the football field, the leisure square, etc., and the advantage of the white light is that the distortion is not yellow, but the illumination range is wide and the transmittance is good. And the LED lights, light efficiency, energy saving, environmental protection, expensive, high-power LED lights installed, heat dissipation technology can not pass, in such a high place is still not appropriate. I hope it works for you. Shengda street lamp dedication.

Q: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

Q: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.
