Lighting System Reducing Physioneural Compression via Temporal Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting systems experience reduced perceived brightness due to physioneural compression, where the human eye integrates visual information from multiple cone cells, leading to decreased brightness perception.
Innovation Solution
A lighting system comprising multiple light sources emitting light within specific wavelength ranges corresponding to long, medium, and short cone cells, with a controller alternating their operation to maintain a duty cycle shorter than the visual cortex's response time but longer than the physioneural cells', thereby reducing physioneural compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources emitting different wavelengths are used simultaneously, then color rendering is improved, but perceived brightness is reduced due to physioneural compression
Solution Approach 1:
The patent applies periodic action by sequentially activating different light sources at different times rather than simultaneously. The controller activates first and second light sources in alternating sequences with durations shorter than the visual cortex response time but longer than physioneural cell response time. This temporal separation prevents physioneural compression while maintaining color rendering through sequential wavelength stimulation.
2Loss of information
If light is emitted to stimulate multiple cone cell types simultaneously, then color information is enriched, but brightness perception is compressed
Solution Approach 1:
The patent segments the stimulation of different cone cell types into separate temporal intervals. Instead of stimulating long, medium, and short cone cells simultaneously which causes compression, the system activates light sources targeted at specific cone cell types in sequence. Each light source stimulates a specific cone cell type during its activation window, preventing physiological compression while preserving color information through temporal segmentation.
3Illumination intensity
If conventional lighting systems operate continuously, then illumination is maintained, but energy consumption increases
Solution Approach 1:
The patent employs periodic action with duty cycles shorter than the visual cortex response time to maintain illumination while reducing energy consumption. The light sources are activated in periodic sequences rather than continuously, leveraging the persistence of visual perception to maintain illumination appearance while significantly reducing actual energy consumption during the off-periods between activations.

AI summary
A system for generating light with reduced physioneural compression. The system includes a first light source operable to emit light within a first wavelength range corresponding to a first photoreceptor and a second light source operable to emit light within a second wavelength range corresponding to a second photoreceptor. The system includes a controller functionally coupled to each of the first light source and the second light source. The controller is configured to alternately operate one of the first light source and the second light source with a duty cycle that is less than a response time of the visual cortex, but greater than a response time of physioneural cells, optionally including a latency between operation of light sources. The system may further include a third light source corresponding to a third photoreceptor.
