Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED strips face issues with voltage instability and brightness reduction due to series connections, and operational failure due to open circuits, while parallel connections lead to increased current load and voltage drops, affecting overall performance.
Innovation Solution
A system with a main controller and sectional controllers, each equipped with voltage reduction modules, stabilizes power supply and controls LED strips independently, ensuring stable voltage and brightness even if individual units fail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If LED units are connected in series, then voltage can be supplied to each LED unit, but the supply voltage drops rapidly and becomes unstable as the number of LED units increases
Solution Approach 1:
The LED strip system is divided into multiple independent segments, each with its own control circuit. The controller is segmented into multiple channels, each independently controlling a group of LED units. This segmentation allows voltage stabilization at each segment level, preventing cumulative voltage drop across the entire strip.
Solution Approach 2:
The patent transitions from a single-dimensional series connection to a multi-dimensional control structure where LED units are arranged in parallel groups, each group controlled by a separate channel. This dimensional change from linear series to hierarchical parallel-series structure enables independent voltage management for each group.
2Reliability
If LED units are connected in parallel, then stable voltage can be supplied to each LED unit and failure of one unit does not affect others, but the current load increases causing voltage drop
Solution Approach 1:
The parallel-connected LED units are grouped into segments, with each segment controlled by a separate channel of the controller. This segmentation reduces the current load on each individual power supply path while maintaining parallel connection benefits for reliability and independent operation.
3Adaptability or versatility
If the number of parallel-connected LED strips increases, then more LED units can be controlled independently, but the current load of the entire system increases causing voltage drop
Solution Approach 1:
The controller is divided into multiple independent channels, each capable of controlling a group of LED strips. This channel-based segmentation allows independent control of different LED groups while distributing the total current load across multiple independent power paths, preventing system-wide voltage drop.
Solution Approach 2:
The patent introduces a multi-channel control dimension, where each channel operates independently to control specific LED groups. This adds a control dimension that allows selective activation and independent management of different LED segments, reducing overall system current load while maintaining control versatility.

AI summary
A system for controlling, and capable of sectionalized voltage stabilization of, RGB or RGBW light-emitting diode (LED) strips includes a main controller and a plurality of sectional controllers. The main controller can connect with more than one sectional controller at the same time. Each sectional controller is provided therein with a voltage reduction module and can be coupled in parallel, and supply electricity stably, to a plurality of LED strips (which may be RGB or RGBW LED strips). The main controller is configured to receive and process an externally input operation signal and output a main control signal. Each sectional controller is configured to receive and analyze the main control signal and control the ON time, current, and light emission interval of each corresponding LED strip according to the corresponding instruction in the main control signal in order to effect various changes in light.
