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:The top LED lights always burn the bulb in series

A simple circuit based on resistance current limiting can only be adjusted with current resistance.

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

Led 2 polar tube inside chip oscillator circuit, and the general appearance led 2 polar tube without distinction, only connected to the power supply of two kinds of color turns light, 1 seconds, I bought the 5MM red, blue autoflash. From the appearance of the series, but not necessarily in series

Q:Rated voltage of LED lamp string

You are the light string and see how much you a lamp, the lamp voltage for LED in 3.0-3.4V, for intermediate values of 3.2V, N=220/3.2=68.75 so many beads. In fact, we are in terms of LED is a DC device, there is no voltage rating, mainly to see his current value, the work must be steady flow. The power 0.06W LED current is 20MA, the power 0.2W LED current is 60MA, the power is 0.3W, the LED current is 100MA, the power is 1W, the high power LED current is 300-350MA, and so on in turn, ah, I=P/U

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:How does the LED light string flash?

What kind of light? What about the flash?If you are talking about the pulse drive mode of LED, then it is for heat dissipation and energy saving.

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: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

Diode products cannot be calculated by resistors.

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.
