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 many watts are the street lights?

Small common 60 watt city street mercury lamp, sodium lamp 110 and 220.

Q:Is there any national standard for surface coating of LED street lamp?

Yes, there is no specific standard in our country at present, as long as you can wear the standard of corrosion prevention!

Q:How many lights can a high-power LED lamp be at least W?

At this stage of the rural minimum power lights are 20W, 40W, is mainly based on the width of pavement, street lamps light efficiency, light cloth density, the installation height of the future, the light effect is improved, the minimum power may be smaller than the current lights, high power LED lamps, small power can do big to about 80LM/W. Power can do about 90LM/W street.

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 many watts does the LED street light have?

And some businesses, in order to reduce costs, use hundreds of 0.5W small power LED. However, the small power LED light is very serious, its decline to 80% of the life of only 1000 hours. So, as the need for long-term use of lamps is not allowed by this small power LED, with high power LED (usually above 30W), the light will be better.

Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program

611 lights should be divided into at least 10-20 parallel units.

Q:What do you pay attention to when choosing LED street lamps?

Second, LED street lamp protection level (dustproof, waterproof level, generally want to reach IP65 or more)Third, LED lamp shell material and heat dissipation performance should choose reliable.

Q:What is the principle of constant current power supply in LED street lamps?

Inductors, coils, transformers, these inductors are switching power components, one of the main characters,The role is to assume load or pressure, isolation, filtering and so on.All other components, resistors, capacitors, and protective elements are used.

Q:LED good or low frequency electrodeless lamp?

LED is the light produced by hole migration. Electrodeless lamp is an electromagnetic field to excite gas particles. Judging from the current technology, LED is not mature, so electrodeless lamp is better
