LED Solar Street Light of CNBM



FAQ:WHAT'S THE ADVANTAGES OF CNBM?

1.CNBM is a state-owned company under jurisdiction of central goverment , one of  Fortune 500 .Just because of this ,we can get more support and resources from our government.So ,it is realiable .


2.CNBM's solar  products are high-qualified with TUV,UL,VDE,CE,ISO certificates. Our products ranges top in China.

3.Just as I mentioned in attahment ,we signed 500MW project with Urkan under the witness of our chairman Xi Jinping ,CNBM has ability to meet your large quantity needs,Our annual capacity is 1GW.

4.We can offer you a competitive price .Because you are our potential and valued customer .

5.We ,CNBM ,has our own factory :CNBM JETION SOLAR .We can also customize according to customers' need . You can google our factory .

Q:Solar street lamp, 60 watt LED lamp holder, with large battery
Total lighting time per night (temporarily indicated by H);60W the lamp cap is divided by the battery's rated voltage to draw the current (temporarily indicated by A)The number of days required for continuous wet days (temporarily indicated by T);Battery to prevent overcharge and over discharge, generally charged to 90%, discharge more than 20%, take 70% calculation, formula for:Battery capacity = 70% (A*H*T).
Q:How to identify LED street lamps do well or not?
Overall, 1 lumens per watt lamp (what is the value of the lamp lumens not) are now generally more than 85LM.2, the light distribution curve of the lamp is how, now popular is bat wing light effect.
Q:Solar LED street lamp, how much is a set of solar street lamps wholesale price?
Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.
Q:What is the price of the LED street lamp from 30W to 60W? What are the advantages of the LED street lamp?
LED lamp with directional light, low power consumption, good drive performance, fast response speed, high seismic capacity and long service life, environmental protection and other advantages of gradually into people's vision, the world has become a new generation of energy-saving light source, so the advantages of substitution of traditional light, LED lamp will become the best choice for energy saving road lighting. LED street lamp, that is semiconductor lighting lamp, uses light-emitting diode as light source. Because it is a solid cold light source, it has the characteristics of environmental protection, no pollution, less power consumption, high light efficiency and long service life.
Q:Why is the higher the current, the lower the light efficiency?
Because the higher the current, according to Ohm's law, of course, the power will also increase, while the luminous efficiency is the total luminous flux / total power
Q:Do you know the assembly process of the LED street lamp?
The lead out line of the lamp cap is welded with the input end of the power supply, and the two power lead wires of the palm and the white are welded at the output end of the power supply.
Q:What are the benefits of a modular LED street lamp?
LED modular lamp benefits: first heat better, beads scattered, heat accumulation is relatively small, the heat dissipation requirements will be lower;
Q:Can the LED power supply be used as street light power supply?
Pay attention to 2 aspects:Relevant parameters should be met! Such as power, voltage, current, etc.Street lighting power should be waterproof, anti lightning and grounding.
Q:What is the active power of LED street lamp? What is the relationship between input voltage and current and power?
When the alternating current through the load resistor, and the resistance of the AC voltage and AC current through the resistor is the same phase, and between them the phase angle phi = 0 degrees, while the active power consumption in the resistive load, power grid to supply energy. When the alternating current through the pure inductance load, phase AC voltage on the advanced phase of current 90 degrees and the angle between them phi = 90 DEG, produce reactive power in inductive load, power supply of electric energy in the inductor for temporary storage and magnetic energy back to the grid into electricity such a periodic cycle, results for grid is not energy, so that the "reactive power", but "reactive power" and "reactive current" still exist. When alternating current through pure capacitance load, also similar to this, but the phase AC voltage on the lag phase of current 90 degrees and the angle between them phi = - 90 degrees.
Q:Does LED street lights save electricity?
But if using white light LED for lighting, not only light efficiency, and long life (continuous work time of more than 10000 hours), almost no maintenance. At present, the German company Hella LED developed using white light aircraft reading a street lamp; the Australian capital Canberra has used the white LED lighting lamp; city traffic management in China is also white LED to replace the early order of traffic lights. It is foreseeable that in the near future, white light LED will enter the family to replace the existing lighting. LED light source with the use of low-voltage power supply, low energy consumption, strong applicability, high stability, fast response time, no pollution to environment, color light etc., although the price is compared with the existing lighting equipment is expensive, it will inevitably replace the existing lighting device.
