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:What are the power connections for the LED light string?
LED lamp string power connection method: LED light string, general voltage is DC 12V, so need to use switching power supply, power supply according to the size of LED light string and connection length to decide
Q:Led full-color light string and how to control wiring
Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK
Q:The number of lights in the LED string
15 lights, 30 lights, and 60 lights refer to the LED band. How many LED components are welded per meter length?
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:LED lights string broken, how to repair?
LED lights string broken: you can check one by one, which is bad, which change.
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's the average luminous current of an ordinary LED lamp string?
If it is parallel, how much is the number of parallel to you, such as your distribution of LED lamp lights inside the 12 series and 8 (0.2W), then use the current is 60X8=480mA
Q:220vled water lamp string how to connect, that is, 220 of the electricity
The time of the water lamp is controlled by adjusting the capacity value of the capacitor.
Q:Why are there three lines for the controller of the LED light string? What are they?
The LED pipe positive string is connected with 4-5 1K2W resistance strings, and the other end of the resistor is connected with the common positive pole of the controller. LED tube controller's direct bright output (Huang Xian), if the LED tube brightness is not too bright, minus a resistor. Remember not to short-circuit, short-circuit, burn out the controller. The less string LED, the more resistance string.
