Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices either provide static, everyday light or colored light with lower color rendering index, making them unsuitable for both normal lighting and entertainment purposes, lacking the ability to produce dynamic and entertaining light while maintaining suitable illumination characteristics.
Innovation Solution
A system comprising a plurality of luminaires capable of generating polychromatic light, arranged in an array and controlled by a computerized device to produce combined light with selected characteristics, including varying dominant wavelengths and spectral opponency to reduce melatonin suppression, while recreating lighting scenarios from memory or external sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lighting devices provide static light for everyday use, then illumination suitability is improved, but entertainment value deteriorates
Solution Approach 1:
The lighting device transitions from static to dynamic operation by enabling individual control of multiple luminaires through a computerized device. Each luminaire can independently vary its dominant wavelength and intensity over time, allowing the system to adapt between everyday illumination and entertainment modes. This dynamic control resolves the contradiction by making the lighting system flexible enough to serve both purposes sequentially.
2Adaptability or versatility
If conventional lighting devices provide colored light for entertainment, then entertainment value is improved, but color rendering index deteriorates
Solution Approach 1:
The system applies different spectral characteristics to different luminaires within the same system. Individual luminaires can emit light with dominant wavelengths optimized for specific purposes (e.g., wavelengths that render colors accurately versus wavelengths that create entertaining visual effects). This local differentiation allows the system to provide both high CRI illumination and entertaining colored light simultaneously or sequentially in different spatial zones.
3Loss of energy
If conventional lighting devices provide dimmer lights, then energy consumption is reduced, but suitability for normal lighting deteriorates
Solution Approach 1:
The system changes the spectral parameters (dominant wavelength) of the light sources rather than simply reducing intensity. By varying the dominant wavelength of individual luminaires, the system can create entertaining visual effects at lower overall intensity levels, reducing energy consumption while maintaining visual interest. Additionally, the computerized control allows selective dimming of specific luminaires while maintaining full intensity of others, preserving adequate illumination where needed.

AI summary
A lighting system including a plurality of luminaires capable of generating polychromatic light having a dominant wavelength in the visible spectrum and arranged into an array and a computerized device electrically coupled to the plurality of luminaires so as to selectively operate each individual luminaire to produce source light varying with each other and with time. The computerized device operates the luminaire such that each luminaire emits a source light, the source lights combining to form a combined light having selected characteristics. Each of the plurality of luminaires may be operable to emit light having increased spectral opponency, thereby reducing melatonin suppression. The source lights, when perceived directly, recreate a lighting scenario having varying lighting characteristics.
