Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting devices do not efficiently promote biological functions such as ATP production, collagen synthesis, and anti-inflammation, as they do not effectively cover the ATP action spectrum and cytochrome c oxidase absorption peaks.
Innovation Solution
A light emitting device incorporating a LED chip emitting blue light, a red wavelength conversion material, and a near-infrared phosphor with a specific composition (CaAl(12-x-y)Ga y O 19 :xCr 3+< ) that converts light to optimize the emission spectrum to cover a significant portion of the ATP action spectrum, with a peak intensity ratio and full-width-half-maximum (FWHM) tailored for high efficiency biomodulation.

Engineering Contradiction Analysis
1Productivity
If conventional phosphors are used in LED devices, then the device structure is simple, but the efficiency for promoting ATP production and biological functions is insufficient
Solution Approach 1:
The patent uses a composite phosphor system combining CaAlSiN3:Eu2+ red phosphor and CaAl(12-x-y)GalyO19:xCr3+ near-infrared phosphor with the LED chip. This composite material approach creates a multi-wavelength emission spectrum that simultaneously targets both the red light absorption peak (620-670 nm) and near-infrared cytochrome c oxidase absorption peaks (740-820 nm), thereby significantly enhancing ATP production efficiency while managing the complexity through systematic material selection
Solution Approach 2:
The patent optimizes specific parameters of the near-infrared phosphor including composition ratios (x and y values in CaAl(12-x-y)GalyO19:xCr3+), particle size distribution (0.1-10 μm), and concentration (1-20 wt%) to maximize the emission intensity at 740-820 nm wavelength range. These parameter adjustments ensure the near-infrared emission efficiently matches the cytochrome c oxidase absorption spectrum, thereby improving biological function promotion while maintaining manufacturable specifications
2Productivity
If the light spectrum is optimized to cover the ATP action spectrum, then the biomodulation function is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent defines specific parameter ranges for the near-infrared phosphor composition CaAl(12-x-y)GalyO19:xCr3+ where 0 < x ≤ 0.5 and 0 < y ≤ 0.5, with the near-infrared phosphor comprising 1-20 wt% of the total phosphor mixture. These parameter specifications balance the need for optimized ATP action spectrum coverage with manufacturable tolerance ranges, allowing production while maintaining enhanced biomodulation efficiency
Solution Approach 2:
The patent assigns different functional roles to different phosphor components: CaAlSiN3:Eu2+ provides red light emission (620-670 nm) for one absorption peak, while CaAl(12-x-y)GalyO19:xCr3+ provides near-infrared emission (740-820 nm) for cytochrome c oxidase absorption. This local quality differentiation allows each phosphor to be optimized for its specific wavelength range, achieving comprehensive ATP spectrum coverage through coordinated local optimizations rather than requiring uniform precision across all components
