Solution Overview
Problem
Users face difficulties in accurately controlling LED strip illumination modes from a distance, as existing controllers lack effective wireless control solutions for RGB lamp strips.
Innovation Solution
A radio frequency-based RGB lamp strip controller with an input module, radio frequency receiving module, control module, and color adjustment module, enabling wireless control of the lamp strip's color and mode through a radio frequency terminal, including a MOS transistor for color adjustment and a single-chip microcontroller for signal processing, along with a reverse protection circuit for voltage stabilization and a power converter for safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional controller is used for LED strips, then the controller can be placed close to the lamp strip, but the user cannot accurately manipulate the controller within a relatively long distance (e.g., ten meters) to change the illumination mode
Solution Approach 1:
The patent replaces the mechanical/physical connection between controller and lamp strip with a radio frequency wireless communication system. The RF receiving module receives control signals wirelessly from remote terminals, eliminating the need for direct physical proximity while maintaining reliable control through digital signal transmission and protocol processing.
2Reliability
If the power supply is reversely connected, then the circuit may be damaged, but adding protection circuits increases device complexity
Solution Approach 1:
The patent introduces an intermediary protection circuit between the power input and the main circuit components. This protection circuit includes reverse connection detection functionality that prevents damage to the controller and lamp strip when power is reversely connected, while maintaining relatively simple circuit implementation through dedicated protection modules.
