Innovation Solution
A system and method that utilize a switch connected to a line voltage sampling module, a switch action judging module, and a dimming control module to sample and recognize switch actions, allowing for efficient dimming and state reset control of multiple lamps by outputting control instructions to adjust or restore the initial lighting state, eliminating the need for manual synchronization and memory reinitialization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If switch dimming lamps with memory function are controlled by the same switch, then dimming control is achieved, but dimming asynchrony occurs due to detection difference or interference of each lamp
Solution Approach 1:
The control system continuously monitors the switching state of each lamp and provides feedback to the central controller. The controller adjusts the dimming signals based on this feedback to ensure all lamps synchronize their dimming states, resolving the asynchrony issue while maintaining control versatility
Solution Approach 2:
A single switch controller is designed to manage multiple lamps simultaneously, providing universal control capability. The controller can issue dimming commands to multiple lamps through a standardized interface, achieving versatile control without requiring separate controllers for each lamp
2Reliability
If lamps with memory function are used, then lighting state can be remembered, but complex operations are required to restore synchronization and initial states
Solution Approach 1:
The control system automatically detects when lamps are out of synchronization and initiates restoration operations without user intervention. The system self-manages the complex state restoration process, eliminating the need for users to perform manual synchronization operations while preserving memory functionality
Solution Approach 2:
The system pre-configures restoration sequences and stores initial lighting states in memory. When restoration is needed, the system executes pre-programmed sequences that automatically return lamps to synchronized initial states, simplifying user operations while maintaining reliable state memory
3Reliability
If all dimming states are cycled to restore initial lighting state, then proper lighting state can be restored, but user time is wasted and convenience is reduced
Solution Approach 1:
The system pre-stores initial lighting states and restoration sequences in memory. When restoration is required, the system directly retrieves and executes the pre-configured restoration sequence, instantly returning lamps to initial states without requiring users to cycle through all dimming states, thus eliminating time loss while ensuring reliable restoration

AI summary
The present invention discloses a system and method using a switch to realize light fixture dimming and state restoration. The system comprises a switch, a line voltage sampling module, a switching operation determination module and a dimming control module. The switch connects to at least one light fixture. The line voltage sampling module samples a rectified line voltage output and outputs a corresponding voltage level signal according to the size of the sampled line voltage. The switching operation determination module identifies and determines a current switching operation on the basis of the voltage level signal and the duration thereof, and outputs a corresponding control instruction to the dimming control module on the basis of the current switching operation. The dimming control module, on the basis of the control instruction, regulates the lighting state of each light fixture or controls each light fixture to return to its initial lighting state. By identifying and determining switching operations to realize light fixture dimming and state restoration control, the invention can realize a regular dimming function, and can quickly restore the light to a preset initial lighting state. The adjustment process is simple and efficient, and dimming time is greatly reduced.
