Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low and high bay luminaires inefficiently illuminate elongated spaces, creating 'hot spots' and glare above eye level, with inadequate vertical and horizontal surface illumination uniformity, and requiring multiple mounting points.
Innovation Solution
Orientation specific optics and mechanical mounting devices are used to direct light efficiently onto vertical and horizontal surfaces, reducing glare and improving uniformity by using lenses and LED light sources that can rotate and be controlled wirelessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional luminaires are used to illuminate elongated spaces, then light is emitted in all directions, but this creates hot spots and glare above eye level while leaving vertical surfaces inadequately illuminated
Solution Approach 1:
The patent applies local quality by using orientation-specific optics that direct light differently in different directions. The luminaire emits concentrated light beams at specific angles (e.g., 30 degrees from horizontal) to illuminate vertical surfaces at eye level, while reducing light emission in directions that cause glare. This creates non-uniform light distribution tailored to specific spatial zones - bright vertical surfaces at eye level, dimmer areas above and below, and controlled horizontal illumination.
Solution Approach 2:
The patent employs asymmetry through orientation-specific optics that create asymmetric light patterns. Instead of omnidirectional emission, the luminaire produces asymmetric beam patterns with concentrated illumination at specific angles directed toward vertical surfaces. The light distribution is asymmetric with respect to the horizontal plane, providing enhanced vertical surface illumination while minimizing glare in upward directions.
2Area of stationary object
If luminaires are mounted high to cover large areas, then coverage area increases, but vertical surface illumination at eye level becomes insufficient
Solution Approach 1:
The patent applies dimensionality change by transitioning from vertical downward illumination to include horizontal and upward components. The orientation-specific optics redirect light beams at angles (e.g., 30 degrees from horizontal) to reach vertical surfaces that would be inaccessible to purely downward-directed light. This adds a horizontal dimension to the illumination pattern, enabling high-mounted luminaires to effectively illuminate vertical surfaces at eye level across large coverage areas.
3Stability of the object's composition
If multiple mounting points are used for luminaires, then mounting stability improves, but installation complexity and cost increase
Solution Approach 1:
The patent extracts the orientation-control function from the mounting structure itself. Instead of using complex multi-point mounting mechanisms to achieve proper orientation, the luminaire incorporates integrated orientation-specific optics that inherently emit light in the correct directions. This allows simple single-point suspension mounting while maintaining proper illumination patterns, separating the mounting function from the orientation-control function.
