Q: LED street lamp burning black what reason?: For example, when testing, due to the power supply instability caused by instantaneous high voltage, or misoperation caused by large current, static electricity will only occur somewhere above the chip black.

Q: How to judge the light type of LED street lamp?: Either for the manufacturer to provide, or to do their own spectral analysis, the naked eye is not visible

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?: Symmetrical lamp, rod 10 meters high25 illuminance, (10*1.414*2) *10*25/90=77WTherefore, it is recommended to install LED lamp 70~100W30 illumination, 100-120WThe above is based on quality chip light source calculation

Q: What are the parts of a LED street lamp?: Solar energy is one of the most direct the most clean energy, solar energy is a huge amount of renewable energy, each day to reach the earth's surface radiation can be approximately equal to 2.5 millions of barrels of oil, can be said to be inexhaustible. The LED spectra of almost all concentrated in the visible light spectrum, so high luminous efficiency, is generally believed that energy-saving lamp energy-saving 4/5 is a great initiative, but also energy-saving energy-saving lamp LED than 1/4, this is a great reform of solid light source. Solar LED lighting integrates the advantages of solar energy and LED.

Q: What are the prospects for the development of intelligent LED street lamps?: LED Street overall environment tends to be stable, but due to the change of government, corruption and other objective factors, this year LED Street speed was significantly lower than expected, the growth rate slowed down, showing the situation, the market is more rational. According to the Chinese LED lighting industry market outlook and investment strategy planning analysis report "shows prospective", in recent years, Chinese LED lamp market penetration (installation number) on the rise, more than 7% in 2011, reaching 11% in 2012, 2013 LED street market penetration is about 19%. In 2015, China's LED street lamp market reached 23 billion yuan, the overall market penetration of China's LED road lighting products will exceed 45%, and the market space is enormous.

Q: What qualifications does LED street lamp product need? Do you need 3C certification?: 3C certification is called "mandatory product certification system", it is the governments to protect consumers' personal safety and national security, enhance product quality management, in accordance with the laws and regulations the implementation of a product conformity assessment system.

Q: Street lights and signal circuit connections: 1, the characteristics of the LED street lamp - unidirectional, without light diffused lightingEnsure efficiency; page 2, LED street lamp has unique two optical design, will be LED street lightingFurther improve the area required to save energy lighting efficiency; illumination; page 3, LED light source efficiency has now reached 100lm / W, but there is still much room for development, for 250LM / W reasonsThe luminous efficiency of high pressure sodium lamp is only increased with the increase of power; therefore, the enterprise list, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamp; (overall light efficiency is theoretically practicallyOver 250W high pressure sodium lamp is more efficient than LED.

Q: LED lights at home after the power cut slightly bright, and the original street lights related, street lights LED lights, street lights off, led pass, how to solve?: LED lights turn off the light: 1, the switch is cut off the zero line, you can change the line.

Q: What's the reason for the flash of LED street lights?: That's ok:1, the other 18 pull a pair of power lines.2, the front 18 lights closed, leaving only the back 18 can be confirmed.3, the first 18 and the latter 18 do not start at the same time.

Q: How many watts are the street lights?: This comes from the needs of the road. Generally 8 meters below the design of the use of 250W or so street lights, more than 8 meters designed to use 400W high-pressure sodium lamp.
