Adjustable Luminaire Module for Variable Ceiling Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination devices lack the ability to provide adjustable and variable illumination patterns, which limits their flexibility in illuminating different-sized rooms and surfaces effectively, especially in retrofitting existing fixtures.
Innovation Solution
The development of adjustable illumination devices equipped with light-emitting elements (LEEs) and optics that allow for adjustable positioning relative to a housing, enabling independent control of direct and indirect illumination by varying the distance, angle, and rotation of luminaire modules, thereby optimizing light distribution across ceilings and walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional illumination devices are used, then the device structure is simple, but the illumination pattern is fixed and cannot be adjusted for different room sizes
Solution Approach 1:
The patent applies the dynamics principle by making the luminaire module positionable and rotatable relative to the housing. The module can be moved to different positions and rotated to different angles, transforming a static illumination device into a dynamic one that can adapt its illumination pattern to different room sizes and configurations.
Solution Approach 2:
The patent segments the illumination device into a housing and a separate luminaire module. This modular segmentation allows the luminaire module to be independently positioned and rotated, enabling adjustable illumination patterns while keeping the overall device structure relatively simple and manageable.
2Area of stationary object
If the luminaire module is positioned close to the ceiling, then the indirect illumination coverage is limited, but the direct illumination intensity is high
Solution Approach 1:
The patent uses dynamics by allowing the luminaire module to be positioned at variable distances from the ceiling and rotated at different angles. This dynamic adjustment capability enables optimization of both the illuminated area and uniformity of light distribution, resolving the trade-off between coverage area and illumination uniformity.
3Adaptability or versatility
If existing fixtures are retrofitted with fixed illumination devices, then installation is simple, but the illumination cannot be customized for different applications
Solution Approach 1:
The patent applies dynamics by enabling the luminaire module to be positioned and rotated, providing customizable illumination patterns for different applications while maintaining relatively simple operation through mechanical adjustment mechanisms suitable for retrofitting existing fixtures.

AI summary
Illumination devices with adjustable optical elements configured to provide a variable illumination pattern of an area are described. The adjustable optical elements of the illumination devices can be traversed relative to a surface (e.g., a ceiling of a room) to vary the light distribution and/or intensity to the surface.
