Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing low and high bay luminaires inefficiently distribute light, creating 'hot spots' and glare above eye level, failing to uniformly illuminate vertical and horizontal surfaces in elongated spaces, and requiring multiple mounting points.

Innovation Solution

Orientation specific optics and mechanical mounting devices are used to direct light efficiently to vertical and horizontal surfaces, allowing a single-point attachment and reducing glare by aligning luminaires with space geometry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional luminaires are mounted above elongated spaces, then light is emitted toward the floor, but light distribution becomes inefficient with hot spots above eye level and insufficient illumination at eye level

Engineering Contradiction:

Improvelight distribution uniformityVSAvoidenergy waste

Core Design Contradiction:

Illumination intensityVSLoss of energy

Solution Approach 1:

The patent applies local quality by using orientation-specific optics with different optical characteristics for different regions. The luminaire includes a first portion with first optics directed at a first vertical surface and a second portion with second optics directed at a second vertical surface, allowing each region to have optimized light distribution tailored to its specific illumination needs and viewing angles.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent employs asymmetry through orientation-specific optics that have asymmetric light distribution patterns. The optics are designed to direct light preferentially in specific directions based on the luminaire's orientation relative to vertical surfaces, creating non-uniform light distribution that is optimized for the specific application rather than symmetric distribution in all directions.

Inventive Principle:

Principle #4Asymmetry

2Object-affected harmful factors

If conventional luminaires are used, then light is emitted in all directions, but glare is generated above eye level

Engineering Contradiction:

Improveglare reductionVSAvoidlight distribution balance

Core Design Contradiction:

Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent converts the potentially harmful effect of direct light emission into beneficial reflected illumination. By directing light at strategic angles toward vertical surfaces and utilizing reflection, the system transforms what would be direct glare into indirect, diffused illumination that reduces glare while maintaining effective lighting levels.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of operation

If multiple mounting points are used for luminaires, then stable support is achieved, but installation complexity increases

Engineering Contradiction:

Improveinstallation simplicityVSAvoidmounting structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies universality through a universal mounting interface that accommodates different luminaire orientations and configurations. The orientation-specific optics are designed to work with a standardized mounting system that can adapt to various installation scenarios, allowing the same basic mounting structure to serve multiple functions and orientations without requiring complex custom solutions for each case.

Inventive Principle:

Principle #6Universality (Multi-functionality)
