Q:What's the reason that the LED street lights flash out?

In addition, there may be LED damage. Among them, LED short-circuit, resulting in the number of LED series to reduce, LED voltage at both ends of low, low beyond the power output voltage range, at this time the power will protect, there will be flash phenomenon.

Q:How much is the power supply voltage of street lamp LED?

220V AC through the LED power, converted to DC 35V voltage supply to the chip, LED chip can only withstand DC 35V voltage!

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:Do ballast ballasts need to be used for starting the LED street lamp?

LED requirements are constant current power supply, some can also use switching power supply, but the cost is relatively high

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 is the price of the LED street lamp from 30W to 60W? What are the advantages of the LED street lamp?

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:The design idea of LED intelligent energy-saving street lamp

I do street power supply, single road constant flow, character ratio is very high

Q:What are the after-sales service of solar LED street lamps?

Solar LED street before construction to do a good job of understanding and good view field field survey and field wiring error on the construction drawings on location, to prevent buildings or trees blocking the sun solar lights and solar battery check is good, prevent LED lamps installed on the back after work in the process of transportation and reinstall the check whether there is damage

Q:What is the LED lamp light?

LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good.

Q:The power supply of LED street lamp has no influence on the grounding power. The possibility that the power supply will burn out is not big enough

The ungrounded words are easy to produce static electricity is not good for the lamp and IC.
