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 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

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

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 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.

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

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: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?

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.
