Solution Overview
Problem
Existing lighting systems lack efficient control over correlated color temperature (CCT), which is crucial for achieving desired lighting conditions in various environments, as they often rely on manual adjustments and lack intuitive user interfaces for dynamic CCT changes.
Innovation Solution
A wall controller with a user input interface, communication interface, and control circuitry that allows users to set and adjust CCT levels, providing real-time feedback and enabling communication with lighting fixtures to control LED arrays, thereby dynamically adjusting the color temperature based on user input and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED-based lighting fixtures are used to replace incandescent and fluorescent bulbs, then energy efficiency and light quality are improved, but control complexity increases due to the need for electronic control circuitry
Solution Approach 1:
The patent introduces a wall controller as an intermediary device that simplifies the user interface for controlling LED lighting fixtures. The wall controller includes a display showing a visual representation of the lighting fixture and allows users to interactively adjust CCT by manipulating the visual display, thereby hiding the underlying control circuitry complexity from the user while maintaining precise control over the LED fixtures' color temperature
2Ease of operation
If manual adjustments are used for CCT control, then device complexity is reduced, but ease of operation and ability to achieve desired lighting conditions deteriorates
Solution Approach 1:
The patent employs color changes in the visual representation displayed on the wall controller to indicate different CCT levels. The display shows a visual representation that changes color or appearance based on the current color temperature setting, allowing users to intuitively understand and adjust the lighting conditions without dealing with complex technical parameters. This makes CCT control as simple as adjusting visual appearance while providing precise control over the actual lighting output
3Loss of information
If real-time feedback is provided to users, then ease of operation is improved, but device complexity increases due to additional sensors and processing
Solution Approach 1:
The patent implements a feedback mechanism where the wall controller's display continuously shows the current CCT level through visual representation. The system receives CCT control inputs from the user, processes them, and immediately reflects the changes in the visual display. This closed-loop feedback provides users with real-time information about the lighting conditions without requiring complex additional sensors, as the feedback is achieved through processing and display of control signals already present in the system
Data Source
AI summary
A wall controller that is used for controlling CCT is disclosed. A user input interface allows a user to provide a CCT parameter by pressing a button, entering a value, or the like. The user output interface can provide the user with an indication of a CCT level, which may represent an actual or current CCT level, a maximum or minimum CCT level setting, or the like for an associated lighting fixture. The communication interface facilitates communications with the associated lighting fixture. The control circuitry is configured to receive user input via the user interface; send a signal based on the user input toward the lighting fixture via the communication interface; and control the user output interface to provide the indication of the CCT level. The signal based on the user input may be indicative of an increase or decrease in CCT level, a specific CCT level, or the like.
