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

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

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:The top LED lights always burn the bulb in series: If the regulator is powered, it is necessary to lower the voltage

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:220vled water lamp string how to connect, that is, 220 of the electricity: On the way of C1, R1, L1, R2 varistor, the primary power supply filter circuit, can input the instantaneous pressure filter, C2, R2, C4, C3 step-down circuit, L2 varistor and filter circuit is composed of rectifier, the filter, which can effectively protect the LED by high pressure breakdown.

Q:The color temperature of LED light string: Light source temperature is different, light color is also different:The color temperature is below 3300K, the color is red, and gives a warm feeling. There is a sedate atmosphere and a warm feeling.The color temperature is in the middle of 3000--6000K, and there is no obvious visual psychological effect in this hue, and there is a refreshing feeling. It is called neutral color temperatureColor temperature exceeds 6000K, light color slants blue, give a person with cool feeling, commonly referred to as cool color temperature.

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: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: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;
