Light Source Control Set for Brightness Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light control switches, such as rotate type and simple on/off switches, lack the ability to fine-tune light brightness and require re-adjustment each time the lamp is turned on, failing to maintain the desired brightness level.
Innovation Solution
A control set comprising an electronically connected control module, adjustable power switch, control chip, and storage unit that generates and stores fine tuning signals to gradually adjust lamp brightness, with a timing unit setting a preset effective period for maintaining the last brightness setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotate type switch is used for fine tuning light brightness, then the brightness can be adjusted, but the brightness cannot be fixed and requires re-adjustment each time the lamp is turned on
Solution Approach 1:
The patent implements a feedback mechanism where the control module detects the brightness adjustment state and stores it in memory. When the power switch is turned on, the system retrieves the previously stored brightness setting and automatically restores it, creating a closed-loop feedback system that maintains brightness settings across power cycles without requiring manual re-adjustment
Solution Approach 2:
The system performs self-service by automatically remembering and restoring the last brightness setting without user intervention. The control module autonomously manages the brightness retention function by storing settings in memory and automatically applying them upon power-on, eliminating the need for users to manually adjust brightness each time the lamp is turned on
2Device complexity
If a simple on/off switch is used, then the device complexity is low, but it cannot be used for fine tuning light brightness
Solution Approach 1:
The patent makes the simple on/off switch multi-functional by integrating it with a control module that can detect both the power state and the brightness adjustment state. The switch not only controls power on/off but also serves as an input for brightness adjustment, allowing a single component to perform multiple functions without increasing physical complexity
Solution Approach 2:
The control module acts as an intermediary between the simple on/off switch and the brightness adjustment function. It translates the basic on/off switch input into both power control and brightness control signals, enabling fine-tuning capability while keeping the physical switch structure simple
3Measurement precision
If the brightness is gradually increased to preset brightness and then decreased, then the brightness control precision is improved, but the time required for adjustment increases
Solution Approach 1:
The system performs preliminary action by pre-calculating and storing the optimal brightness sequence in memory. When brightness adjustment is needed, the control module retrieves the pre-stored sequence and executes it automatically, eliminating the need for real-time calculation and manual adjustment, thus reducing adjustment time while maintaining precision
Solution Approach 2:
The patent changes the control parameter from real-time manual adjustment to pre-stored brightness sequences. The control module uses stored brightness level data and timing information to automatically execute the brightness adjustment sequence, transforming the adjustment process from a real-time interactive parameter change to an automated playback of pre-defined parameters
Data Source
AI summary
A control set for adjusting the light source is provided. The control set includes a control module. The control module includes a control chip and a storage. The control chip controls the brightness of the lamp. The storage connected with a timing unit and stores a fine tuning signal. The fine tuning signal stored in the storage is generated and output to the adjust signal by turning off and turning on the adjustable power switch, the timing unit sets a preset time period in which the fine tuning signal maintains effective, and the fine tuning signal controls the lamp to have a brightness the same as the brightness when the lamp is turned off last time, or the brightness of the lamp is gradually increased to the preset brightness and then decreased.
