- Q:How much is a minimum price of 20 meters high pole lamp? How much is the general price?
- In fact, that's what we usually call energy-saving lamps, LED lights.Different power LED lights, the price is not the same.Resulting in price differences and different processes, different appearance, material, comparative advantages and competitive advantages, as well as new shortcomings of neon and LED lightsCompared to the neon lights and LED lights, the latest LED technology comes into comparison, not what information you see in the network before.
- Q:How to select suitable driving power for LED street lamp?
- LED street lamp driver. Working outdoors, poor environment, the temperature variation of four seasons a year, the summer sun, winter cold, but also accept the rainstorm, lightning shock, so all kinds of tolerance need to be considered.
- Q:How much illumination can the 200 Watt LED projector reach 30 meters?
- There was a beam of lightAn ultra narrow beam of 30 metersProgressive illumination
- 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:What's on 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: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:How about the high pole lighting radius 40m
- Lamp: generally refers to a new type of lighting device more than 15 meters 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 requirements, the surrounding environment, and specific lighting needs; inside the lamp by floodlights and cast light lamps, lamp using NG400 high pressure sodium lamp, lighting the radius of 60 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:What is in the lamppost of the LED street light?
- The cross flow source acting on the current steady light effect reached stable effect and pressure welcome to Yangzhou Henghui lighting equipment Co., Ltd. cooperation the company specializing in the production of LED street lamp solar street traffic signal lamp and high power LED
- 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.
