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: 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?: LED lamp can string together end to end, with more than 24 fluorescent lamp series, bulb lamp with 5X1W5 lamp series, and 6 series and 14.

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: 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: In general, 1210 specifications of the band is 60 LED per meter, 5050 specifications of the band is 30 LED per meter, the special has 60 LED per meter.

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: Example: if I want to do a 40 head low voltage lamp string, do 10 lights, 1 loop, transformer is 150MA, then how can I calculate the resistance? The grid is 60 Hz of China's power grid! Give a formula, and then count the examples. What is it?! Thank you: Diode products cannot be calculated by resistors.

Q: What's the price of the LED light string?: The LED panel lamp has 4 aluminum substrates on each side and has 2 aluminum substrates on each side. 600x600 is about 1.5 yuan each.

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
