Q:What is the difference between the brightness and illuminance of LED street lights and the brightness and illumination of ordinary high-pressure sodium lamps?

There must be a difference... Normally。 A 100W LED street lamp, as long as done well, solve the problem of heat dissipation. The light distribution is good and can be equated to a 250W high pressure sodium lamp

Q:What's the reason why the LED street lights don't work?

Fault phenomenon 1, all LED does not light 1), if the reason is: city power protection switch trip, hit it, and if the power is not bright, generally LED drive power failure,

Q:In the solar street lighting system, who is the LED driver connected to? How to choose the LED driver power?

It is based on a few strings and a few beads to choose, of course will also consider the power, are generally mounted to the lamp holder, but now generally used one of the cross flow controller

Q:How much is the price of a LED street lamp?

The price involves many aspects, generally, for main roads around 120W 1100~1300 are normal; for the auxiliary road around 60~80w 500~800 prices are.

Q:How many volts is the wind power streetlight led?

The difference between LED street lamp and conventional high-pressure sodium lamp street lamp is that the light source of high-power LED street lamp adopts low voltage direct current power supply and high efficiency white light diode synthesized by GaN based power blue LED and yellow phosphor

Q:How much is the LED street lamp with six meter pole?

The light pole is about 1000. Look what kind of lamp holder you want. There are 200 to eight hundred or nine hundred

Q:How can I get the LED street light?

General LED exports are mostly indoor lighting and display, LED street lamps are relatively small. Export products are to be certified, I do not know where you are going to export, as Japan began in July 1st, lamps began to need PSE certification, and the other is at least 3C certification. Without certification, you can only pay for it. There is no right to import and export, but also to find the mouth agent company, and very troublesome.

Q:Solar LED street lighting industry prospects really so good?

All may be bad, and the solar street lamp power is low, can not meet the lighting requirements. It is better to use the LED directly to connect the city power, and the savings of solar panels and batteries are less than the direct payment of the electricity, and the stability is better, and the maintenance is reduced.

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 light is still very serious, uneven quality, used for a long time, as black as under the lamp
