Q:LED lights string broken, how to repair?: Connect the electricity. Can be shorted one by one. It's shining. This is just short of bad beads.

Q:What is the connection distance of the LED light string?Be specific: When the installation must be installed according to the manufacturer's requirements, do not let the LED lamp string overload operation. I use the Zhongshan Greenman, which has detailed instructions, easy connection

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:The number of lights in the LED string: 15 lights, 30 lights, and 60 lights refer to the LED band. How many LED components are welded per meter length?

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: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: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:Performance and characteristics of LED lamp string: 1.LED lamp string can handle perforation lamp string processing;2.LED lights string may through seven colors and full-color controller to achieve colorful jump, gradient, monochrome, full-color, fluttering and other effects.

Q:Section LED lantern, no controller, can shine principleTwo now reduced brightness string string: LED string:Light emitting diodes, referred to as LED, are made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.

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: In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.
