Q:How to use ZigBee intelligent LED street lamp

Because every time there is a street lamp, through the method of adding repeaters, ZigBee can now add more than 60 thousand devices for a city should not be a problem, if more street number more than 60 thousand, can be divided into several pieces respectively. In general, the distance from each repeater is about 70 meters, and it will be better if there is no blocking outside, and hundreds of meters are no problem at all. If the effect is not good, you can add a repeater in the middle to resolve it.

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:How is the minimum illuminance of LED street lights Emin obtained? How to calculate?

Minimum illumination Emin, if you go to calculate or use lighting software (DIALux) simulation, you can get the minimum illumination Emin, how to simulate this? This is not clear

Q:How much is the LED street lamp?

This side needs to provide the lamp post caliber, wall thickness, height, in addition, Kazakhstan needs to provide light source size and lamp cap style, so as to accurately quote the price.

Q:How to judge the light type of LED street lamp?

Either for the manufacturer to provide, or to do their own spectral analysis, the naked eye is not visible

Q:How many kinds of power do LED street lights have? How much brightness can it replace the high pressure sodium lamp? What kind of power does the general main road need?

There are 50 watts, 100 watts, 150 watts, and others with 60708090120 watts. They usually use 90-150 watts.

Q:What is the function of the microcontroller on the LED street lamp?

Can be used to adjust the light, can also be used to determine the timing of the street lights, the key depends on what the microcontroller peripherals, and then use procedures to achieve peripheral functions

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 is the LED lamp light?

LED (Light, Emitting, Diode) light emitting diode is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.

Q:The cold white light LED lamp beads or warm white beads?

And neutral white LED light source skin tone is more natural. Therefore, the choice of neutral white better.
