Lighting Apparatus Frame Buffer for Communication Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting apparatuses that modulate light according to an illumination pattern, such as a moving image, experience user discomfort due to interruptions in the reception of the image caused by communication environment deterioration.
Innovation Solution
A lighting apparatus with a receiver, light modulator, storage, and detector that stores frames of the illumination pattern and uses stored frames to continue modulation when an interruption occurs, ensuring a natural and continuous light output by switching between normal and storage modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the lighting apparatus uses real-time reception of illumination patterns, then the light modulation responds quickly to changes, but communication interruptions cause user discomfort
Solution Approach 1:
The system pre-accumulates a plurality of frames of illumination pattern data in a buffer before they are needed for light modulation. This preliminary storage of data ensures that when communication interruptions occur, the lighting apparatus can continue modulating light using the buffered frames without sudden stoppages or changes, thereby maintaining reliability while still enabling quick response during normal operation.
2Reliability
If the lighting apparatus stores multiple frames in buffer, then interruption comfort is improved, but device complexity increases
Solution Approach 1:
The lighting apparatus automatically manages the buffer of illumination pattern frames through its control unit, which handles the accumulation, selection, and utilization of buffered frames without requiring external intervention or complex manual management. The system self-regulates by detecting communication status and autonomously switching between using real-time received frames and buffered frames, thereby maintaining reliability while keeping the management process integrated and relatively simple.
3Reliability
If the lighting apparatus uses stored frames during interruption, then user comfort is maintained, but information freshness decreases
Solution Approach 1:
The system ensures continuous light modulation by switching to buffered frames when communication is interrupted, maintaining the useful action of illumination without interruption. The control unit monitors communication status and seamlessly transitions between real-time and buffered frame usage, ensuring that the light output remains continuous and smooth, thereby prioritizing the continuity of the lighting function over the timeliness of the illumination pattern during interruption periods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces user discomfort by maintaining a natural light output even during communication interruptions, as the lighting apparatus uses stored frames to modulate light, preventing sudden changes or stoppages in the illumination.
Implementation Method 1
a light source; a light modulator which, every time the receiver receives a frame among the frames, modulates light emitted from the light source
Data Source
AI summary
A lighting apparatus includes: a light modulator which modulates light emitted from a light source, using frames received by a receiver; an illuminator which emits the modulated light; and a controller. The controller periodically performs a storage control which continues for a predetermined period of time and in which, every time the receiver receives a frame, the received frame is stored into a storage. When a detector detects an interruption in the reception of the frames at the receiver, the light modulator modulates the light emitted from the light source, sequentially using two or more consecutive frames stored into the storage.
