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: How do you connect the LED lights?: A series of even parallel. Are not clear, boss, you want to use LED do what?There is a gap, which is the positive pole of the LED (usually the long foot is short and the foot is negative)

Q: 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: 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.

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: 220vled water lamp string how to connect, that is, 220 of the electricity: The triode acts as a switch in the circuit, and when the circuit is through, the left LED is first lit. The base is connected with a capacitor to connect the collector of the next triode.

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: 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: 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: 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: How much is the voltage across the 20 LED lamps in series?: LED lighting general LED lamp belt voltage, conventional specifications are 12 volts and 24 volts, if it is 12 volts, that voltage is 420 volts, if it is 24 volts, that is 840 Volts
