Segmented Lighting Device for Biological Rhythm Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices are inadequate in addressing the biological needs of individuals, as they fail to provide discreet and variable lighting that effectively supports the sleep-wake rhythm, and their installation is often expensive and complex, requiring sufficient room height and offering limited color and radiation options.
Innovation Solution
A lighting device with at least two light source groups, where one group's illumination area lies entirely in the first hemisphere and the other in a second half-space, allowing for indirect and direct lighting, with overlapping illumination areas enabling dynamic color mixing and dimming to adapt to biological needs, and can be installed simply and cost-effectively as a pendant or floor lamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting devices are used to provide high light intensity and focused illumination, then good viewing conditions are achieved, but the lighting does not adapt to biological needs and is perceived as intense external influence
Solution Approach 1:
The lighting device is segmented into multiple light source groups (first light source group for indirect lighting, second light source group for direct lighting) that can be independently controlled. This segmentation allows different lighting modes to be activated separately, enabling adaptation to biological needs while maintaining visual comfort through indirect lighting options.
Solution Approach 2:
Different light source groups provide different lighting qualities - the first light source group provides soft indirect lighting by illuminating ceiling elements, while the second light source group provides direct focused lighting. This local quality differentiation allows the system to adapt to various biological needs and usage scenarios.
2Adaptability or versatility
If backlit luminous ceiling is used to simulate artificial sky, then biological needs are well addressed, but installation is expensive and complicated requiring sufficient room height
Solution Approach 1:
The invention extracts the essential function of indirect lighting from the complex backlit ceiling system. Instead of requiring a fully backlit ceiling structure, the first light source group provides indirect lighting by illuminating ceiling elements, achieving the biological rhythm support function with a simpler, more installable configuration.
Solution Approach 2:
The lighting device uses standard LED light sources and common mounting structures (pendant or floor lamp configurations) that are inexpensive and easily replaceable, eliminating the need for expensive custom-built backlit ceiling installations while maintaining the core functionality.
3Adaptability or versatility
If backlit luminous ceiling is used for dynamic lighting, then biological needs are addressed, but installation requires sufficient room height and offers limited color options
Solution Approach 1:
The lighting device is divided into independent light source groups that can be controlled separately, enabling dynamic lighting scenarios without requiring a backlit ceiling structure. This segmentation allows flexible installation in various room heights while maintaining dynamic lighting capabilities.
Solution Approach 2:
The lighting device provides multiple functions - indirect lighting, direct lighting, and dynamic color control - in a single universal unit that can be installed in different room configurations. This multi-functionality eliminates the need for specialized backlit ceiling installations while achieving the same dynamic lighting effects.
4Adaptability or versatility
If multiple light source groups with overlapping illumination areas are used, then color mixing and dimming options are expanded, but device complexity increases
Solution Approach 1:
The device is segmented into distinct light source groups with different functions (indirect and direct lighting), each controllable independently. This segmentation provides color mixing capabilities through coordinated control of the groups while keeping the overall device structure manageable and not overly complex.
