Q:Low voltage LED lamp string resistance is how to count, there is no formula?
If you direct the transformer to the LED lamp power supply, the life of the LED lamp will be affected, far less than the nominal value.
Q:Rated voltage of LED lamp string
When normal luminescence, each LED voltage drop is more than 2 volts, the current is about 15mA, to use 220V direct current should be connected in series with nearly one hundred led, or in the LED circuit series resistance, so that the series circuit current is about 15ma.
Q:How do you connect the LED lights?
Connect the first LED positive pole to the negative electrode of the second LED and then connect the first LED negative pole with the second LED positive pole to the power supplyConnect the positive pole of each LED with the positive pole of the positive electrode, and then connect to the power supply. This is the parallel connection
Q:What is the principle of the LED series?
Led 2 polar tube inside chip oscillator circuit, and the general appearance led 2 polar tube without distinction, only connected to the power supply of two kinds of color turns light, 1 seconds, I bought the 5MM red, blue autoflash. From the appearance of the series, but not necessarily in series
Q:What's the price of the LED light string?
The power supply is also the most important factor affecting the price of LED panel light. The power is not good, directly affect the LED panel lamp life. UL power supply performance is relatively stable. The price is about 53 yuan, TUV power supply price is about 33, and other CE power supply.
Q:What's the average luminous current of an ordinary LED lamp string?
General LED patch to 0.2W, 0.5W, 0.2W lamp current is 60mA, 0.5W beads 150mA,
Q:Who knows how the controller of outdoor LED lights can be protected against water?
If you don't have a shell, it's an open controller, so you can make a waterproof plastic lid and make it waterproof at the front of the O loopYou can refer to the LED waterproof flashlight for inspiration!
Q:Led full-color light string and how to control wiring
Three line full color exposure lamp data signal two, the controller needs two wire negative electrode control, GND signal connected to the DAT surface
Q:How much is the voltage across the 20 LED lamps in series?
LED lighting general LED lamp belt voltage, conventional specifications are 12 volts and 24 volts, if it is 12 volts, that voltage is 420 volts, if it is 24 volts, that is 840 Volts
Q:How does the LED light string flash?
Because of the special volt ampere characteristics, LED can not use constant voltage driving mode, but is driven by cross flow. The direct drawback of cross flow drive, however, is heat. So people invented the drive mode of pulse drive. For example, 0.5 seconds per second, so that the amount of heat in the LED is reduced by half. Then turn the frequency up to 100 times per second, lighting for 0.005 seconds each time. At this point, the power of the LED is not the same, and people do not feel blinking. What's more, in this driving mode, an approximate cross flow drive (that is, the current is not necessarily precise) can be simplified, which simplifies the drive circuit (the precise cross flow source is very complex)
