Multi-view lighting units for directional brightness control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional architectural lighting systems cannot create different lighting experiences for viewers at various locations, as the brightness and color appear uniform to all viewers regardless of their position, limiting the ability to provide personalized or dynamic lighting effects.
Innovation Solution
A multi-view architectural lighting system that uses multi-view lighting units capable of individually controlling brightness and color in different directions, allowing for distinct lighting experiences for different viewers by mapping light directions to viewing locations and using a controller to manage the appearance of each light unit from various angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional direct-view or indirect-view lighting is used, then the lighting system is simple and easy to implement, but all viewers at different locations see the same uniform lighting experience
Solution Approach 1:
The patent segments the lighting system into multiple independently controllable light sources arranged in arrays, where each light source can be individually controlled to emit light in specific directions. This segmentation enables different viewing zones to receive different lighting patterns from the same physical lighting system, resolving the contradiction between lighting experience differentiation and system complexity.
Solution Approach 2:
The patent implements local quality by making each light source emit light with specific directional characteristics tailored to particular viewing zones. Each light source can have different intensity, color, or temporal patterns directed toward different spatial locations, allowing the same lighting system to provide customized lighting experiences for viewers at different positions without requiring completely separate lighting systems for each zone.
2Adaptability or versatility
If light sources transmit light uniformly in all directions, then the lighting system is easy to manufacture and install, but it cannot provide differentiated lighting content for different viewing locations
Solution Approach 1:
The patent employs dynamic control of light emission characteristics, where each light source can dynamically adjust its emission pattern, intensity, and color based on the desired viewing zone. This dynamic capability allows the lighting system to adapt to different viewing locations and provide zone-specific lighting content without requiring physically different fixtures for each location, thus maintaining ease of manufacture while achieving viewing zone specificity.
3Adaptability or versatility
If multiple lighting systems are used to provide different lighting experiences for different viewers, then lighting content differentiation is achieved, but system complexity and cost increase significantly
Solution Approach 1:
The patent achieves universality by designing a single lighting system that can simultaneously serve multiple viewing zones with different lighting patterns. The same array of light sources can dynamically configure different lighting patterns for different spatial locations, eliminating the need for multiple separate lighting systems. This multi-functionality resolves the contradiction by providing lighting pattern differentiation through a unified, adaptable system rather than through proliferation of separate systems.

AI summary
A multi-view architectural lighting (MVAL) syste m i n c l u d e s one or more multi-view lighting units ("MV lights") in which the apparent brightness and color of each MV light is individually and simultaneously controllable for different viewing angles. The MV lights can be pointed in arbitrary directions and installed in arbitrary locations in 3D space with respect to one another, consistent with the structure of a building, etc. This enables a lighting designer to create differentiated lighting experiences for different viewers based on their viewing angle with respect to the MV lights. A calibration system maps viewing locations to emitted light directions for each MV light. Using this information, the appearance of each M V l i g h t from a given viewing location relative to that MV light is set by adjusting the light (e.g., typically color and intensity, etc.) emitted in the corresponding direction/directions.
