Q:What role does the light controller and driver play in the LED street light component?: At present, the pulse drive chip is powered by a high frequency pulse generator output interface to the LED lamp. Because the pulse signal frequency is very high, so the human eye can not feel the LED strobe, so this method meets the visual needs, and on the one hand, effectively save the power output. Also, the frequency of this type of chip can generally be controlled by an external interface. However, the current frequency of this type of chip is generally in the range of 100KHz~500KHz. So the current drive capability is only suitable for low power applications. However, I believe that in the near future will be elevated to high-power LED driver occasions.

Q:Is the price of the street lamp factory in led the same?: LED lights for their respective products factory price countries has not been unified, now rely on market regulation and macro-control and their purchase of LED street customer awareness of the product, the key is led lamps factory enterprise conscience.

Q:What are the components of a LED street lamp?: Street lamp pole, support arm, lamp (constant current power supply, light emitting system)

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:What are the standards for LED street lights?: Generally not too high standards, the whole system is a combination, but the material is different

Q:How much is the price of the LED street lamp?: Photovoltaic street lamp environmental protection, safety, long life, can be made according to user requirements.

Q:How to judge the light type of LED street lamp?: It will be tested by a large distributed photometric tester,

Q:How to select suitable driving power for LED street lamp: LED lamp driving power supply for outdoor work, 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:Is there any difference between intelligent street lamp and intelligent LED street lamp?: The difference is that the light source of the latter has been defined as LED. The light source of the former is not defined and can be a variety of light sources.

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.
