Q: The top LED lights always burn the bulb in series: If it is a constant current drive, there is a special adjustment element to adjust the current.

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: If you don't have a shell, it's an open controller, so you can make a waterproof plastic lid and make it waterproof at the front of the O loopYou can refer to the LED waterproof flashlight for inspiration!

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: 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 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: 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: The 1.LED light string is led by a light emitting diode packaged in an imported chip;The design of light angle 2.LED lamp string of the larger angle angle of >120 degrees, uniform mixed color, no color;3.LED lamp string selected LED dedicated constant voltage power supply mode, circuit design for constant current circuit, the work performance is very stable, so as to ensure normal life >5 hours;

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: If you direct the transformer to the LED lamp power supply, the life of the LED lamp will be affected, far less than the nominal value.

Q: What is the connection distance of the LED light string?Be specific: LED light string connection distance: in general, the 3528 series of LED lights belt, its connection distance is the longest 20 meters, 5050 series of LED lights string, the longest connection distance is 15 meters

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.
