Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LED light emitting devices are used, then basic lighting function is provided, but light biomodulation function for enhancing human health and ATP production is not achieved
Solution Approach 1:
The patent applies parameter changes by precisely controlling the compositional parameters (x and y values) of the near-infrared phosphor material CaAl(12-x-y)GayO19:xCr3+ to achieve specific emission characteristics. By adjusting these compositional parameters, the phosphor emits light with peak wavelength of 740-820 nm and FWHM of 90-110 nm, which optimally matches the ATP action spectrum for biological effects while maintaining high conversion efficiency from blue LED excitation.
Solution Approach 2:
The patent employs composite materials by combining blue LED chips with the specifically formulated near-infrared phosphor CaAl(12-x-y)GayO19:xCr3+ to create a hybrid light emitting system. This composite structure integrates the high-efficiency blue light emission of LEDs with the wavelength-converting properties of the phosphor material, producing final light that covers both the blue region (400-470 nm) and near-infrared region (740-820 nm) necessary for comprehensive light biomodulation effects.
2Adaptability or versatility
If near-infrared phosphor is added to LED device, then light biomodulation function is achieved, but device structure becomes more complex
Solution Approach 1:
The patent applies merging by integrating the near-infrared phosphor conversion layer directly onto the blue LED chip structure, combining multiple functions (blue light emission, near-infrared conversion, and biomodulation effect) into a single integrated device. This eliminates the need for separate light sources or complex optical systems, achieving light biomodulation functionality through a unified phosphor-converted LED structure.
3Illumination intensity
If broad emission spectrum is used, then coverage of ATP action spectrum is achieved, but intensity in specific bands becomes diluted
Solution Approach 1:
The patent applies parameter changes by precisely controlling the compositional parameters (x and y values) of the near-infrared phosphor material CaAl(12-x-y)GayO19:xCr3+ to achieve specific emission characteristics. By adjusting these compositional parameters, the phosphor emits light with peak wavelength of 740-820 nm and FWHM of 90-110 nm, which optimally matches the ATP action spectrum for biological effects while maintaining high conversion efficiency from blue LED excitation.
