Abstract
A LED strip comprises at least three colors of LEDs and at least three signal lines, and an LED with one color is connected between every two signal lines; it further includes control components with the same number as the signal lines, and the control components are connected to one end of the signal lines; tit further includes a control system coupled with the control components and used for sequentially and circularly outputting two groups of control signals, thereby sequentially and circularly driving the two control components, and the total number of control signals output by the control system is not less than the number of LED colors.
Claims13
A light emitting diode (LED) strip, wherein said strip comprises at least three LEDs with different colors and at least three signal lines, and an LED with one color is connected between every two signal lines;
- and
- wherein, the LED strip further comprises control components with a same number as said signal lines, and said control components are respectively connected at one end of said signal lines;
- and
- wherein the LED strip further comprises a control system coupled with said control components and used for outputting two groups of control signals, and a total number of said control signals output by said control system is not less than a number of LED colors;
- wherein each group of said control signals comprises a first signal and a second signal;
- and wherein said first signal is a Pulse Width Modulation (PWM) signal with a duty ratio of 0 to 100%, and said second signal is a PWM signal with a duty ratio of 0 or 100%;
- two groups of said control signals are output to two corresponding control components to turn on the LED/LEDs connected between two signal lines that are connected to the two corresponding control components;
- the at least three LEDs are driven to turn on one after another in cyclic sequence.
A light emitting diode (LED) strip color modulation method, wherein at least three control components are respectively coupled to a control system and signal lines with a same number as said control components, and an LED of one color is connected between every two signal lines;
