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: How do you connect the LED lights?: Connect the first LED positive pole to the negative electrode of the second LED and then connect the first LED negative pole with the second LED positive pole to the power supplyConnect the positive pole of each LED with the positive pole of the positive electrode, and then connect to the power supply. This is the parallel connection

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: Different LED number of LED light band price is different, and this is also to distinguish LED lamp belt price is an important factor.

Q: Section LED lantern, no controller, can shine principleTwo now reduced brightness string string: 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: 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: LED lights string broken, how to repair?: LED lights string broken: you can check one by one, which is bad, which change.

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?: Don't know what kind of LED, if it is ordinary bright LED words, according to different colors, the rated voltage between 3.6-3.8V (current allowable level <20mA), you can be calculated according to the amount of estimates, as long as the control current should not exceed 20MA no problem

Q: What are the power connections for the LED light string?: This advantage can be centralized control, inconvenience is unable to achieve a single LED light string lighting effect and switch control, which specific way can be measured by their own. I use the LED lamp string is Zhongshan Greenman with total power and parallel connected to
