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

No specific standards, the main anti-corrosion can be

Q:How many LED lights are there in the downtown area, W?

Depends on the width of the road, the normal is 250W metal halide lamp, there are 400W.. Used at intersections,

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

The LED lamp power is waterproof power, bad to change new power protection function is not perfect, directly affect the quality of fault phenomenon LED lamp 2, bad part there are several possibilities: 1), such as LED lighting power supply for multi-channel constant output, which may be a group of bad, 2) is LED chip is not good, or is the LED lamp cooling caused by bad burn LED chip.

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:What is the heating temperature at the LED street lamp?

You ask this question is not clear, good heat dissipation, low temperature, poor heat dissipation, the general surface temperature is best not more than 70 degrees, each LED street lamps are not the same

Q:LED technical requirement of street lamp 100W

(5) the environmental temperature of LED street lamp should be -20 to +50 centigrade, and other special requirements such as temperature, humidity and corrosiveness of the local environment should be satisfied.(6) the power factor is greater than or equal to LED 0.95 lamps, lamp power supply efficiency is more than 95%.(7) the working voltage range of LED street lamp is from 85V to 265V (in this voltage range, LED lamps can still work normally).(8) LED street lamp has surge suppression performance (against lightning stroke), the input over-voltage protection, when the voltage is restored to normal, can resume work.

Q:Who knows the relationship between the number and weight of LED street lamp

The relationship between the number of LED light weight and beads, the strength of your life,Can not get a formula, a single lamp can be 1W, or 100WThe relation between street light weight and street lamp power can still be obtained, only at presentDie casting space aluminum cooling, about 100W, about 20 pounds

Q:Is the LED courtyard light a LED street light?

Secondly, the garden lamp grounding should be careful and serious, grounding wire should be set, along the courtyard lights into a network, and not less than 2, in order to ensure that short circuits, reduce accidents.After the circuit has been connected, it can be officially used for inspection and ensure safety. If the lamp doesn't work, you need to continue to check the circuit.This is the use of city power LED street lights, Zaozhuang Jetion photoelectric solar lamp, there are also suitable for scenic spots, residential areas, villas style, it does not need such a complex process

Q:Does the LED street lamp need a starter?

LED light is not a starter, is a constant current source module, is 220V city power rectifier, with constant current circuit to each LED lamp power supply; LED lights can be connected in series, and then parallel. There is also not constant current, but in each series of branch current limiting resistors, to consider the range of voltage fluctuations, select the current resistance resistance value and power.

Q:Solar street lamp, 60 watt LED lamp holder, with large battery

This is calculated according to the number of days of continuous illumination under the condition that there is no solar charge.
