Q: I have just entered the line, I would like to know what the main quality of LED street lighting?: Think there are three reasons, one is the lamp cooling effect, two lamp quality, three is the quality of driving power, the other I do not know, I was in Guangzhou to do the LED lamp power supply, but also good, let me happy is a 100 R & D team. Hope to adopt

Q: How much is a full set of solar street lamps?: Independent research and development, production of solar LED street lamps, solar street lamps, solar energy, wind energy complementary street lamps. In the design, R & D - production of solar LED street lamp broke the three big problems of solar streetlight common (high power, LED decay quickly, no power output) seriously affect the cost and efficiency of the lamp. The cost is greatly reduced and the service life is increased. More distant after-sales service and quality guarantee, so that the promotion of solar street lamps, energy-saving work further. The following is the design of solar street side of the company: the overall design basically takes into account all aspects; the design method is currently the most common photovoltaic component peak wattage selection design and battery capacity selection design by the design idea of comparative science; wind resistant design from the battery assembly support and pole two to do the analysis, comparison and analysis comprehensive; surface treatment technology is the most advanced by the whole structure is simple and beautiful; street lamp; after the actual operation proves that the link between good matching.

Q: What are the prospects for the development of intelligent LED street lamps?: Before 2015, LED Street will remain around 50% compound annual growth rate, by 2015, LED road lighting lamps in the field (mainly for street lights and tunnel lamp) the overall penetration rate reached 46%, the next two years will add more than 30 million LED street lights and tunnel lamp. These favorable expectations have brought greater potential for development of LED street lamps.

Q: Is there any difference between intelligent street lamp and intelligent LED street lamp?: LED light is generally used as a light source, there is no difference between open and close appliances intelligent streetlights.

Q: Do constant current LED power supply for street lamp power supply? Is it better to use LED constant voltage power supply?: General is constant current power, street light is not clear, but 90% are constant current power.

Q: What is the reason that the longer the wire pulls on the LED street lamp, the lower the voltage?: Wires have resistances. The longer the wires or wires, the smaller the resistance, the greater the resistance.

Q: What are the specifications of LED street lamps?: The integrated specifications go up from 30W to one specification per 10WSingle from 28 onwards, each 14W for one specificationModules from 30W onwards, each 30W for one specification

Q: What's the reason for the flash of LED street lights?: Should be the power line station, power supply to a startup, behind the low voltage, so the lights flashing.

Q: What is the problem of flashing LED street lights on the side of the road?: If all the lights of the LED are flashing, it is likely that the supply current and current are not normal

Q: What is the starting current of the LED street lamp for 220V and 30W?: Unlike an energy-saving lamp, LED needs to be started with a high voltage, but normally lit, of course, the lighting current will be slightly larger, mainly because the capacitor is usually used for filtering
