Q:What happens if the LED street is ungrounded? Is it a big problem?
The LED itself is very sensitive to lightning surge currents, which can cause damage to the human body by electrostatic touch and burn chips or leads. Therefore, the street lighting circuit must be grounded.
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:In the solar street lighting system, who is the LED driver connected to? How to choose the LED driver power?
LED drive power is generally installed in the solar street lamp holder
Q:What heat sink is best for LED street lamp radiator?
What is the external force of heat, force, that is to say, with the use of external heat, fan in the lamps or using superconducting tube, water-cooled, and so on, the advantage of active heat dissipation, efficiency has been improved, but the structure is complicated, the cost is increased, and the service life of the cooling equipment is generally not too long, less than 2 years is basically finished.
Q:What is the starting current of the LED street lamp for 220V and 30W?
But the influence is very small, so it can be considered as the starting current is the rated current, and the rated current = power / voltage = 30/220 = 0.136A
Q:Why does a LED street lighting system come with a phase light?
Because the LED light current is in the Ma level and slightly leaks, the current will shine.
Q:What are the components of the LED street lamp holder structure?
The surface of the lamp has been treated with UV resistance and corrosion resistance, and the overall lamp meets the IP65 standard. The outer cover can be made of PC tube, and the temperature can be up to 135 degrees.
Q:What are the necessary tests for the factory inspection of the LED street lamp?
One is to use open mold, the overall shell heat dissipation, the first type of heat dissipation problem is not solved, the second type of higher cost, as for other fans, heat pipes, heat conduction membrane, and the heat is deceptive.
Q:The design idea of LED intelligent energy-saving street lamp
Sound control is not recommended...The timing control circuit can be added in the driving power source to adjust the current supply of the LED light source to realize intelligent dimming.The advantages of this approach are relatively easy to implement and low cost.
Q:LED street lights generally use how many W, how much density is more appropriate?
100W or so, the distance is about the same as ordinary street lights!
