Q: What is the grade of protection for Mega LED road lamp holder?: Protection level. First mark numbers indicate contact protection and foreign object protection level. Second mark numbers indicate waterproof protection grade. General: IP65, the highest level is IP68. Siu Chang street protection grade is IP65, can also be customized to do IP68.

Q: The power consumption of a street lamp?: Also consider ballast power dissipation

Q: What is the active power of LED street lamp? What is the relationship between input voltage and current and power?: When the AC current is over load, the AC voltage added to the load generates a phase difference with the AC current through the load, and the concept of power factor is derived from it. People produce and live electricity from the grid, which provides alternating current of 50Hz or 60Hz. As AC load, there are three types of resistance, inductance and capacitance.

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: Does the LED street lamp 80W or 100W need to be compensated by a single light capacitor?: Traditional high-pressure sodium lamp street lamp end voltage is low, use compensation capacitor, otherwise the voltage is too low, it is difficult to start. LED street lamps rarely use capacitive compensation, because now LED street lamps are using wide voltage drive power, and some start voltage is below 100V, can be lit normally.

Q: How much is the LED street lamp?: Should not be cheap, power 200W or so, the main driver expensive

Q: What are the 6 main disadvantages of LED street lights? What are the 6 major disadvantages?: 1 single LED power low. In order to obtain high power, more than one parallel connection is needed.TwoLow color rendering index.It is a technical problem that the color displayed by LED radiation is not true of incandescent lamp, and it should be analyzed from the spectral distribution.

Q: LED lights at home after the power cut slightly bright, and the original street lights related, street lights LED lights, street lights off, led pass, how to solve?: LED lights turn off the light: 1, the switch is cut off the zero line, you can change the line.

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: What is the reason for the low power factor of LED street lamp?: The LED street light power is generally more than 100W, if the power factor is low, it can only show that its driving power supply, there is no power factor correction, or is not done well.Well done, it should be more than 0.95.
