Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lighting strips lack individual control over LEDs, resulting in monotonous lighting effects and are limited by data loss and voltage fluctuations, restricting their length and application in long-distance cascade connections.
Innovation Solution
The LED lighting strip employs a serial-parallel connection for power and serial communication protocol, allowing for easy control and regulation of each LED, enabling long-distance cascade connections and diverse lighting effects by using multiple LED modules connected in parallel and series on conductive lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If through-hole LEDs or surface-mounted LEDs are used with serial connection, then single-color or multiple-color LED lighting strips can be provided, but individual control of single LEDs is not possible and lighting effect is monotonous
Solution Approach 1:
The LED lighting strip is divided into multiple independently controllable LED modules, where each module contains at least two LED lighting beads. This segmentation allows individual control of each LED module while maintaining the ability to create diverse lighting effects across the entire strip.
Solution Approach 2:
The patent implements dynamic control capability by enabling individual addressing of LED modules through the serial communication protocol. This allows the lighting system to transition from static, monotonous lighting to dynamic, individually controllable lighting effects.
2Length of stationary object
If power carrier solutions are adopted, then LED lighting strips can be manufactured, but data loss from voltage fluctuation and cascade connection stages limits the length and feasibility for long-distance cascade connection
Solution Approach 1:
The patent introduces a dedicated communication conductive line as an intermediary for data transmission, separate from the power-supplying conductive lines. This intermediary channel transmits control signals and data without being affected by voltage fluctuations in the power lines, enabling reliable long-distance cascade connection.
Solution Approach 2:
The patent segments the electrical connections into separate functional pathways: power-supplying conductive lines for electrical power delivery and a communication conductive line for data transmission. This segmentation allows the communication signals to remain stable and loss-free even over long distances with multiple cascade connection stages.
3Adaptability or versatility
If LED modules are connected in parallel on power-supplying conductive lines with series connection of LED lighting beads, then power supply flexibility is improved, but manufacturing and installation complexity increases
Solution Approach 1:
The patent designs LED modules with standardized multi-functional terminals that can simultaneously handle power input, power output, and communication signal transmission. This universal interface design simplifies manufacturing and installation by allowing the same modular component to be used in various power supply configurations without requiring different connection methods.

AI summary
A light-emitting diode (LED) lighting strip includes conductive lines and LED modules. The LED module includes LED lighting beads electrically connected with the conductive lines and arranged orderly on the conductive lines to form a strip. One of the conductive lines is a communication conductive line, and the remaining three are power-supplying conductive lines. On the communication conductive line, the LED lighting beads are connected in series. On the power-supplying conductive lines, the LED modules are connected in parallel, and the LED lighting beads of each LED module are connected in series. The LED lighting strip adopts an arrangement of serial-parallel connection for power and serial connection for signal to achieve various application solutions for different power supply voltages, and as a consequence, a serial communication protocol is adopted to control each of the LED lighting beads of the LED lighting strip, in order to realize diversification of lighting effect.
