FAQ

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
LED lights string broken, how to repair?
Connect the electricity. Can be shorted one by one. It's shining. This is just short of bad beads.
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
The top LED lights always burn the bulb in series
If the regulator is powered, it is necessary to lower the voltage
Hanging on the tree string lights, each one is 10 meters long, with a controller, I asked the factory with the AB protection, but the manufacturers say that only do the general anti rain, no water, even the rain stop, I want to use plastic wrap, don't know? Which expert can give advice and advice? emergency
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!
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)
What are the power connections for the LED light string?
If you do not want to use a power to control each LED lamp string, can switch power to buy a relatively large power for the total power supply, then put all LED light on the input power (all parallel wire size is not enough, can also extend) unified by the total power switch.
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.
