- Q:How much is the voltage across the 20 LED lamps in series?
- Each LED is about 3V, and the 20 series is 60V
- Q:Why are there three lines for the controller of the LED light string? What are they?
- Common positive (red line +) is the positive pole for each street lampThree road cycling (blue line) this four lines are respectively connected with the four colors of LED tube anode side run. When the positive pole is connected to the common cathode, remember that the resistor must be connected first to connect to the positive electrode of the LED tube. The bright output (white) is the word to make it bright
- 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)
- Q:What is the connection distance of the LED light string?Be specific
- LED light string connection distance: in general, the 3528 series of LED lights belt, its connection distance is the longest 20 meters, 5050 series of LED lights string, the longest connection distance is 15 meters
- Q:LED lights string broken, how to repair?
- As an emergency treatment, you can also short-circuit the open circuit of the LED lights. Used to restore normal work.
- Q:How do you connect the LED lights?
- Connect the bottom edge of the triangle symbol to the high voltage and the sharp angle to the low voltage. The bottom edge of the next LED is connected with a sharp angle
- Q:What is the principle of the LED series?
- When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
- Q:The top LED lights always burn the bulb in series
- If the regulator is powered, it is necessary to lower the voltage
- 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: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.
