Q:What is the active power of LED street lamp? What is the relationship between input voltage and current and power?
Here, we define the phase angle advance as positive, and the phase angle lag as negative. The actual load is resistance, inductance, capacitance inductance capacitance of three types of complex, composite after referred to as "impedance", written in mathematical is: Z= R+j. where R is the resistance impedance, XL inductance, XC capacitance. If > 0, known as the "perceptual load"; conversely, if < 0 called capacitive load. Alternating current through the inductive load, the phase voltage of the alternating current phase advance; alternating current through the capacitive load, the lag phase alternating current AC voltage; electrical engineering definition of the power factor angle phi angle of power factor angle phi Cos phi is called the cosine value of power factor. For resistive load, the voltage and current of the phase difference of 0 degrees, therefore, the power factor of the circuit is 1 of the maximum; and pure inductance circuit, voltage and current phase difference of 90 degrees, and is a leading current voltage; in pure capacitance circuit, voltage and current phase difference is - 90 degrees. The current leading voltage. In the latter two circuits, the power factor is zero. For a general load circuit, the power factor is between 0 and 1. By mathematical impedance Z=, R+, J, if XL = XC, then Z= R, that is, impedance Z becomes a pure resistor, power factor is equal to 1.
Q:What are the 6 main disadvantages of LED street lights? What are the 6 major disadvantages?
Light LEDAfter a period of illumination, the light intensity of LED will be lower than that of the original light
Q:What happens if the LED street is ungrounded? Is it a big problem?
If a lamp holder is expensive, it should be sold for ten thousand yuan. If it is not damaged by grounding, it will be more harm than good.
Q:Who knows LED street lamp warm white light and positive white light have what difference, how should choose?
If the power is the same, the brightness of the white and warm white light should be the same.
Q:I have just entered the line, I would like to know what the main quality of LED street lighting?
I am a technician of LED power supply company, and I have been working for several years.
Q:How much is the LED street lamp with six meter pole?
A little better. The price for the end customer is about 10 dollars a watt.The price of the lamp post is not fixedIn general, if the pole shape is nothing special,6 meters pole may be about 400-600.This answer is recommended by the questioner
Q:Does the LED street lamp 80W or 100W need to be compensated by a single light capacitor?
Capacitor compensation is reactive power compensation or power factor compensation. The power system of electric equipment in use will produce reactive power, and is usually inductive, it will make use of the capacity of power efficiency, and by increasing the capacitance of the way properly in the system can be improved.
Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program
611 lights should be divided into at least 10-20 parallel units.
Q:What is the principle of constant current power supply in LED street lamps?
Inductors, coils, transformers, these inductors are switching power components, one of the main characters,The role is to assume load or pressure, isolation, filtering and so on.All other components, resistors, capacitors, and protective elements are used.
Q:How to judge the light type of LED street lamp?
It will be tested by a large distributed photometric tester,
