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?
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: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?
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 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: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
Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK
Q:What is the connection distance of the LED light string?Be specific
When the installation must be installed according to the manufacturer's requirements, do not let the LED lamp string overload operation. I use the Zhongshan Greenman, which has detailed instructions, easy connection
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 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)
