Q:Why are there three lines for the controller of the LED light string? What are they?
The four cycles are green, blue and white, and the answer is almost the same as that on the top. But the three colors are strung together
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:Rated voltage of LED lamp string
When normal luminescence, each LED voltage drop is more than 2 volts, the current is about 15mA, to use 220V direct current should be connected in series with nearly one hundred led, or in the LED circuit series resistance, so that the series circuit current is about 15ma.
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:220vled water lamp string how to connect, that is, 220 of the electricity
On the way of C1, R1, L1, R2 varistor, the primary power supply filter circuit, can input the instantaneous pressure filter, C2, R2, C4, C3 step-down circuit, L2 varistor and filter circuit is composed of rectifier, the filter, which can effectively protect the LED by high pressure breakdown.
Q:What's the average luminous current of an ordinary LED lamp string?
General LED patch to 0.2W, 0.5W, 0.2W lamp current is 60mA, 0.5W beads 150mA,
Q:The color temperature of LED light string
Generally speaking, the color temperature is not an indicator of the LED band, but many foreign customers will make a special request because of the use of the environment.
Q:Low voltage LED lamp string resistance is how to count, there is no formula?
Diode products cannot be calculated by resistors.
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:Led full-color light string and how to control wiring
Three line full color exposure lamp data signal two, the controller needs two wire negative electrode control, GND signal connected to the DAT surface
