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 bottom edge of the triangle symbol to the high voltage and the sharp angle to the low voltage. The bottom edge of the next LED is connected with a sharp angle

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: There are grades of waterproof and dustproof, and the methods from 0 to 9. are different!I think you should use, can prevent the rain, and shallow water immersion!This is easy to handle. When the controller is made, if it has a shell, touch 703 glue at the joint! General circuits are frequently usedIn fact, many LED production plants have LED filling glue and waterproof!

Q: How does the LED light string flash?: LED because of its special structure, frequent startup does not reduce its service life, but high temperature can significantly shorten its life. So cooling is important for LED.

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: 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: 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.

Q: What's the price of the LED light string?: The power supply is also the most important factor affecting the price of LED panel light. The power is not good, directly affect the LED panel lamp life. UL power supply performance is relatively stable. The price is about 53 yuan, TUV power supply price is about 33, and other CE power supply.

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
