Q:What are the main uses of LED street lamps?: Street lights must be used on highways, such as roads, highways, urban roads, parks and so on

Q:What are the advantages of LED road lights?: Conducive to environmental protection. LED light for all solid body, shock resistance, impact resistance is not easy broken, no pollution.

Q:How many kinds of power do LED street lights have? How much brightness can it replace the high pressure sodium lamp? What kind of power does the general main road need?: Generally have 20W, 30W, 50W, brightness can be replaced by 100W, 150W, 200W power high-pressure sodium lamp 30W~50W power is enough for a common trunk road.

Q:Does the LED street lamp need a starter?: LED light is not a starter, is a constant current source module, is 220V city power rectifier, with constant current circuit to each LED lamp power supply; LED lights can be connected in series, and then parallel. There is also not constant current, but in each series of branch current limiting resistors, to consider the range of voltage fluctuations, select the current resistance resistance value and power.

Q:How many lights can a high-power LED lamp be at least W?: At present the market street lamp lens material for the improvement of optical materials, transmittance is more than 93%, high temperature -38 +90, anti ultraviolet UV ` etiolating rate for 30000 hours without change. It has a very good application prospect in the new city lighting. Dimming for depth, and colors and other features are not subject to dimming.

Q:What heat sink is best for LED street lamp radiator?: Is natural heat dissipation, what is called natural heat dissipation, that is, rely on the lamp's own radiator to dissipate heat, and now most of the market is fin type heat sink, this advantage lies in the cost point, passive heat dissipation time. However, the disadvantage is that the heat dissipation is very slow, far less than the high-power heat dissipation requirements. Good service life is less than 2 years. But recently, the market has a kind of through-hole type heat radiation lamp, break the traditional heat dissipation concept, increased the heat dissipation surface, let the air form convection. The cooling effect is remarkable. You should be interested in discussing LED lighting technology, so you can leave a contact. I'm technical. Hope to be adopted

Q:The width of the road is 20 meters, the distance of the street lamp is 25 meters, and the number of tiles is led. How much is the pole?. How to calculate?: General road light source is about 250W,If you use LED, there are enough 72---108W, but the earlier to buy more expensive lights, in terms of long-term interests, LED to energy-saving much more cost-effective.The lamp pole is 7----12 meters high and the distance is 30----45 meters.Zhejiang Yao Liang lighting specializing in the production of various types of outdoor lights.

Q:LED street lights generally use how many W, how much density is more appropriate?: 100W or so, the distance is about the same as ordinary street lights!

Q:How to maintain the LED street lamp?: LED is best used within 3 months of its original packing condition to prevent the stent from rusting. When the LED bag is opened, it should be used as soon as possible. At this time the storage temperature is 5 degrees -30 degrees centigrade and the relative humidity is below 60%.

Q:How to choose the power of solar street lamp?: Disadvantages: the distance of energy saving lamp is short and the illumination can not be satisfied. Energy-saving lamp light generally 10-20%, energy-saving lamp life in about 8000 hours, the maintenance cost is high; the main comments: energy-saving lamp suitable for commercial lighting, Home Furnishing lighting and plant lighting, not suitable for road lighting. 2, street lamp energy-saving cabinet, the energy-saving equipment mainly through the reduction of the overall voltage of the line, to achieve the purpose of energy saving.
