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?

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.

Q: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.

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

A high pole lamp power, there are some low power courtyard street lamp, a power voltage, there are low, are prone areas in lightning, so the constant current drive, not only good performance, but also can be good heat dissipation, anti lightning, anti rain.

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

Luminous flux, high luminous efficiency, color rendering, but too expensive, in recent years, will not decline. However, it can increase the luminous flux of the product, thereby reducing the cost of replacing incandescent lamps.

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: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: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?

LED lamp wall traditional street lighting area, good lighting effect, light source, uniform illumination, glare, easy control and maintenance.

Q:How much illumination can the 200 Watt LED projector reach 30 meters?

Look at the optical parameters of the 200WLED projector
