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?
65 of the LED tubes are connected with 3-4 resistors. One end of the resistor is connected to the positive electrode of the LED, and the other end of the resistor is connected to the common anode of the controller. The blue wire is attached to the negative electrode of the LED tube.
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:I want to do a string of LED lights that can use batteries. About 55 or so. The lights are 5MM blue. How can I work? Urgent urgent!!
If it is a general common blue LED working current is 20 mA, voltage of about 2.5V can be lit, the battery power can be used in parallel, the benefits of this connection is one of the damage does not influence the normal operation of other LED. And each LED string to a current limiting resistor, LED protection lamp, prolong life, calculation formula of the resistance for V / 0.02A=: voltage current resistance: 3V, battery powered =3 / 0.02=150. You want to supply 55 LED batteries to work together, the total current is up to 0.02x55=1.1A, i.e. 1AH (ah) capacity of the battery can work 1 hours or so.
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: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: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
A simple circuit based on resistance current limiting can only be adjusted with current resistance.
Q:Low voltage LED lamp string resistance is how to count, there is no formula?
In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.
Q:Who knows how the controller of outdoor LED lights can be protected against water?
You can use the plastic wrap, mouth down, so even if again under the rain is not bad. Or glue the entire controller to the point where the water is likely to enter the water.
