Multi-mode Solid-state Lighting Panel for Illumination and Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid-state lighting panels lack the ability to provide both general illumination and communicate information effectively, as they typically serve only one function without additional functionality.
Innovation Solution
A multi-mode solid-state lighting panel system that includes multiple solid-state light emitters and a controller capable of switching between illumination and communication modes, using first and second color emitters to convey messages and images, with the ability to receive input signals from environmental sensors or central controllers to dynamically adjust lighting configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If solid-state lighting panels are used for general illumination only, then illumination effectiveness is improved, but functional versatility deteriorates
Solution Approach 1:
The lighting panel is designed to perform multiple functions: general illumination and information communication. The controller enables the panel to switch between illumination mode and communication mode, allowing the same device to serve both purposes without requiring separate systems.
Solution Approach 2:
The lighting panel is divided into multiple independently controllable light emitter groups. Each group can be selectively activated to provide either illumination or communicate specific information, enabling the panel to simultaneously perform illumination and communication functions or switch between them as needed.
2Adaptability or versatility
If multiple color emitters are added for communication capability, then functional versatility is improved, but device complexity increases
Solution Approach 1:
The same light emitter array serves dual purposes: producing white light for illumination and producing colored light for communication. The controller manages the emitters differently based on the desired function, eliminating the need for separate communication devices.
Solution Approach 2:
The system changes the operational parameters of the light emitters to achieve different functions. By adjusting which emitters are activated and their intensity levels, the system produces either white illumination light or colored communication signals using the same physical components.
3Loss of information
If dynamic lighting configurations are implemented for communication, then information conveyance is improved, but control complexity increases
Solution Approach 1:
The system receives input signals that trigger specific communication responses. The controller interprets these signals and activates appropriate light emitter patterns to convey information back, creating a feedback loop that enables bidirectional communication between the system and users.
Solution Approach 2:
The lighting panel transitions from static illumination to dynamic communication by selectively activating different groups of light emitters in response to input signals. The controller manages these dynamic changes in light patterns to convey various types of information.
