Q: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.

Q:To achieve the following functions of LED lights, what knowledge do you need to use?

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

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 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.

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?

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.

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: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?

Look at the optical parameters of the 200WLED projector
