Lighting Assembly with Patterned Diffusers for Uniform Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
A significant portion of electricity is consumed by lighting, and existing lighting solutions do not efficiently address changing lighting needs or provide uniform illumination.
Innovation Solution
The use of multiple lighting devices with patterned diffusers, each positioned to direct at least 50-95% of emitted light into specific rectangular, square, hexagonal, or octagonal areas on an illumination surface, minimizing light overlap and ensuring uniform coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple lighting devices are used to improve illumination coverage, then the uniformity of illumination is improved, but the device complexity increases
Solution Approach 1:
The illumination task is segmented into multiple discrete lighting devices, each responsible for a specific geometric area (rectangle, square, hexagon, or octagon). Each device contains a light source with an optical element that segments and directs light into its designated zone, ensuring uniform coverage without overlap while reducing the complexity of controlling each individual device.
2Loss of energy
If lighting devices are positioned to direct light into specific areas, then energy efficiency is improved, but the precision of light distribution control increases
Solution Approach 1:
Each lighting device is configured with local quality - its optical elements are specifically designed and positioned to direct light into a particular geometric area with defined boundaries. The optical elements (lenses, reflectors, or diffusers) are tailored to each device's location and orientation, providing precise control over light distribution while maximizing energy efficiency by directing light only where needed.

AI summary
There is provided a lighting assembly comprising a plurality of lighting devices, each of which comprises a patterned diffuser having optical features. Each of the lighting devices is positioned such that if they are illuminated, at least 50, and in some cases 75 or more, percent of light emitted from each of the lighting devices will contact an illumination surface within an area of a defined shape (e.g., square, rectangular, hexagonal, octagonal, etc.), the respective shapes each sharing at least one boundary with another shape. Also, methods of lighting comprising illuminating lighting devices positioned in such a way.
