Orientation Specific Luminaire with Rotating Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current luminaires in elongated spaces, such as aisleways, inefficiently distribute light, creating 'hot spots' above eye level and resulting in glare and uneven illumination, with existing designs unable to uniformly illuminate both horizontal and vertical surfaces effectively.
Innovation Solution
The implementation of orientation-specific optical lenses over LED light sources, coupled with a mechanical orientation mounting device that allows for horizontal rotation and single-point attachment, to direct light more efficiently towards targeted areas on both horizontal and vertical surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional luminaires are mounted above elongated spaces, then light is emitted toward the floor below, but light levels are excessively high above eye level and insufficient at eye level, creating hot spots and glare
Solution Approach 1:
The patent applies local quality by using multiple light sources with different orientations (vertical and horizontal LEDs) to create different light distribution patterns in different spatial zones. Vertical LEDs illuminate the floor area, while horizontal LEDs illuminate the vertical rack faces, ensuring each region receives appropriate illumination without excessive intensity that causes glare
Solution Approach 2:
The patent employs asymmetry by positioning light sources and using asymmetric optical elements (lenses and reflectors) that direct light preferentially toward specific zones. The optical elements are designed to asymmetrically distribute light intensity, concentrating illumination at eye level (3-7 feet) while reducing intensity above this range, thereby eliminating hot spots and glare
2Ease of manufacture
If luminaires are suspended from structure above by cables or chains, then mounting is simplified, but multiple mounting points are required which increases installation complexity
Solution Approach 1:
The patent applies universality by designing a mounting structure that can function in multiple ways: it provides both structural support and orientation adjustment capabilities. The single mounting point incorporates adjustable mechanisms that allow the luminaire to be positioned and angled correctly without requiring multiple fixed mounting points, thereby simplifying installation while maintaining proper light distribution
3Use of energy by moving object
If planar LED light sources are used, then energy efficiency is improved, but light distribution uniformity on vertical and horizontal surfaces is poor
Solution Approach 1:
The patent applies segmentation by dividing the lighting function into multiple independent light sources with different orientations and optical characteristics. Instead of relying on a single planar LED array, the system uses vertically oriented LEDs for floor illumination and horizontally oriented LEDs for rack face illumination, with each segment optimized for its specific target surface, thereby achieving uniform light distribution while maintaining energy efficiency
Solution Approach 2:
The patent employs dimensionality change by transitioning from a two-dimensional planar LED arrangement to a three-dimensional configuration with light sources oriented in multiple directions (vertical and horizontal). This spatial arrangement allows simultaneous illumination of both horizontal floor surfaces and vertical rack faces, improving light distribution uniformity across different planes while preserving the energy efficiency of LED technology

Data Source
AI summary
Orientation specific lensed optics disposed over a light source of a luminaire illuminates vertical and horizontal surfaces regardless of the luminaire form. The luminaire is coupled to a mounting device and the mounting device is free to rotate about its vertical axis to align the luminaire with other like luminaires and/or room geometry while the mounting device is coupled to a structure above by a single point of attachment.
