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

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: 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's the average luminous current of an ordinary LED lamp string?: If the lamp light current series is their rated current,

Q: Performance and characteristics of LED lamp string: 1.LED light string is good. The colors are red, yellow, green, blue, white, warm white and so on;2.LED lamp has the advantages of convenient installation, after one-time injection waterproof, waterproof grade IP65, installation of plastic card, do not need any accessories, you can direct the word in the hole and fixed installation;

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: 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!!: You can use the 4~6V battery, through the 4W, 2~3 Europe (6V with 3 Euro, 4V with 2 Euro) current limiting resistor, to the LED lamp power supply. The parameters of each lamp are: 3V, 20MA, in parallel (polarity). If you don't quite understand, you can also ask a science and engineering student (preferably a teacher) to help.

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.
