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: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:The top LED lights always burn the bulb in series

Do not know what kind of drive you are, try to reduce the current of LED, do not exceed the rated operating current of LED on the line. The method of reducing current is related to drive circuit, and the current limiting method is different for different circuits.

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

The LED panel lamp has 4 aluminum substrates on each side and has 2 aluminum substrates on each side. 600x600 is about 1.5 yuan each.

Q:The color temperature of LED light string

Generally speaking, the color temperature is not an indicator of the LED band, but many foreign customers will make a special request because of the use of the environment.

Q:How do you connect the LED lights?

LED lamp can string together end to end, with more than 24 fluorescent lamp series, bulb lamp with 5X1W5 lamp series, and 6 series and 14.

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:What are the power connections for the LED light string?

LED lamp string power connection method: LED light string, general voltage is DC 12V, so need to use switching power supply, power supply according to the size of LED light string and connection length to decide
