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

The connection distance is 15 meters. If the connection distance is exceeded, the LED light string is easy to heat, and the service life of the LED light string will be affected during use

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:What's the price of the LED light string?

Frame and bottom plateLED panel light frame and bottom plate according to different material, its heat dissipation performance is not the same priceThere are differences. The price of the 6063 aluminum profile is about 50-80 yuan (the specifications are different and the prices are different).

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: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:Why are there three lines for the controller of the LED light string? What are they?

The four cycles are green, blue and white, and the answer is almost the same as that on the top. But the three colors are strung together

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.
