Q:How much is the voltage across the 20 LED lamps in series?

Each LED is about 3V, and the 20 series is 60V

Q:What's the average luminous current of an ordinary LED lamp string?

If it is parallel, how much is the number of parallel to you, such as your distribution of LED lamp lights inside the 12 series and 8 (0.2W), then use the current is 60X8=480mA

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:Led full-color light string and how to control wiring

Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK

Q:The color temperature of LED light string

Refers to a standard blackbody heating, the temperature rises to a certain degree when starting from the color red - Orange - red - white - blue, gradually changed, a light source and the blackbody with the same color, we will at the time of the absolute temperature blackbody called the color temperature of the light source.

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

Common positive (red line +) is the positive pole for each street lampThree road cycling (blue line) this four lines are respectively connected with the four colors of LED tube anode side run. When the positive pole is connected to the common cathode, remember that the resistor must be connected first to connect to the positive electrode of the LED tube. The bright output (white) is the word to make it bright

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;
