Solution Overview
Problem
Conventional lighting systems primarily emit visible light and fail to provide wavelengths beneficial for vitamin D production and cell activation, lacking ultraviolet and infrared components essential for human health.
Innovation Solution
The development of an LED lighting apparatus incorporating light emitting diodes and wavelength converters that emit white light, ultraviolet light for vitamin D production, and specific wavelengths for cell activation, including peak ranges of 286-304 nm, 400-420 nm, and 685-935 nm, to mimic sunlight's benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting systems are used to provide visible light, then illumination function is achieved, but wavelengths beneficial for vitamin D production and cell activation are not provided
Solution Approach 1:
The patent combines multiple LED chips with different emission wavelengths (violet LED at 405nm, blue LED at 465nm, red LED at 630nm, and infrared LED at 850nm) into a single integrated lighting apparatus. This merging approach enables the system to provide comprehensive spectral coverage including visible light for illumination, ultraviolet for vitamin D production, and infrared for cell activation, all within one unified device structure.
Solution Approach 2:
The lighting apparatus is designed to perform multiple functions simultaneously: it provides illumination through visible light emission, promotes vitamin D synthesis through ultraviolet emission, and stimulates cell activation through infrared emission. This multi-functional design allows a single device to address diverse human health needs without requiring separate specialized equipment for each function.
2Adaptability or versatility
If LED lighting apparatus includes multiple light emitting units with different wavelengths, then additional health benefits are provided, but device complexity increases
Solution Approach 1:
The patent integrates four distinct LED light emitting units (violet, blue, red, and infrared) into a single compact apparatus. By merging these different wavelength sources together, the system achieves comprehensive health benefits including illumination, vitamin D production, and cell activation without requiring separate standalone devices for each function.
Solution Approach 2:
The lighting apparatus is segmented into multiple independent light emitting units, each responsible for specific wavelength emission. This segmentation allows each LED unit to be optimized for its specific function while maintaining overall system integration. The modular structure facilitates easier manufacturing, maintenance, and potential customization of individual components.
