Adaptive Interior Illumination System Using Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current illumination systems in interior spaces lack the ability to dynamically adjust light spectrum based on the type of object being illuminated, potentially affecting user comfort and eye health, as they do not differentiate between cool and warm visible spectrums effectively.
Innovation Solution
An illumination system comprising at least one first light-emitting diode for cool visible spectrum and one second light-emitting diode for warm visible spectrum, an infrared light source, and an imager that captures images to categorize objects and generate illumination signals to either or both LEDs based on object type, allowing for adaptive lighting adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light source is used for illumination, then the device complexity is reduced, but the ability to adapt to different object types and optimize user comfort is limited
Solution Approach 1:
The illumination system is segmented into multiple independent LED modules, each capable of emitting different color temperatures (cool white, warm white, neutral white). This segmentation allows the system to selectively illuminate different object types with appropriate光谱 characteristics while maintaining modular device architecture that manages complexity.
Solution Approach 2:
The system dynamically adjusts the illumination spectrum by activating different LED modules based on real-time object detection results. The processor dynamically selects which LEDs to activate based on object category, enabling adaptability without requiring a completely static complex system design.
2Illumination intensity
If multiple light-emitting diodes with different spectrums are used, then the illumination quality and user comfort are improved, but the device complexity increases
Solution Approach 1:
Multiple LEDs with different spectral characteristics are merged into a single integrated illumination assembly controlled by one processor. The cool white LEDs, warm white LEDs, and neutral white LEDs are combined in one system that detects objects and selectively activates appropriate LED groups, providing high illumination quality while consolidating control functions.
Solution Approach 2:
The illumination system achieves multi-functionality by using a single assembly of LEDs that can provide different color temperatures for different object types. The same hardware infrastructure serves multiple illumination purposes (reading, dining, viewing) through spectral selection rather than requiring separate dedicated lighting systems.
3Ease of operation
If the illumination system continuously monitors and adjusts based on object type, then user comfort and eye health are optimized, but the energy consumption and processing requirements increase
Solution Approach 1:
The system uses periodic action by activating the imaging assembly and object detection functions only when needed to identify an object, then maintaining the selected illumination state. The processor periodically reassesses the scene to detect object entry or category changes, rather than continuously monitoring all parameters, thus optimizing user comfort while managing energy consumption.

Function Achieved in This Case

AI summary
An illumination system includes at least one first light-emitting diode that is configured to project a first light within a cool visible spectrum and at least one second light-emitting diode that is configured to project a second light within a warm visible spectrum. An imaging assembly includes an infrared light source that is configured to project an infrared light and an imager that captures an image of a reflection of the infrared light from a surface of an object. A processor is configured to extract a 2-dimensional (“2D”) representation of the object from the image, identify and categorize the object, and generate an illumination signal to at least one of the at least one first light-emitting diode or the at least one second light-emitting diode based on the category of the object to illuminate the object.
