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?

General LED patch to 0.2W, 0.5W, 0.2W lamp current is 60mA, 0.5W beads 150mA,

Q:LED lights string broken, how to repair?

LED lights string broken: you can check one by one, which is bad, which change.

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:Section LED lantern, no controller, can shine principleTwo now reduced brightness string string

When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

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

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

This advantage can be centralized control, inconvenience is unable to achieve a single LED light string lighting effect and switch control, which specific way can be measured by their own. I use the LED lamp string is Zhongshan Greenman with total power and parallel connected to

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: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.
