Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting devices lack the ability to adapt to their environments, resulting in inefficient energy use due to light absorption rather than reflection, and fail to optimize for changing environments, necessitating the need for adaptive lighting systems that can tailor light emissions to match environmental colors.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If current lighting devices emit fixed spectrum light, then device structure is simple, but energy efficiency is poor due to light absorption by environment
Solution Approach 1:
The lighting device dynamically adjusts its spectral output by selectively activating different LED chips (e.g., blue LED with yellow phosphor, green LED, red LED) based on environmental conditions detected by the color sensor. This dynamic adaptation allows the system to optimize energy efficiency by emitting light spectra that reflect off surfaces rather than being absorbed, while maintaining a relatively simple overall device structure through integrated control circuitry.
Solution Approach 2:
The system incorporates a color sensor that continuously monitors the environmental color and provides feedback to the control circuit. The controller processes this feedback and adjusts the intensity and spectral composition of different LED chips accordingly. This closed-loop feedback mechanism enables real-time optimization of energy efficiency without requiring complex mechanical adjustments, resolving the contradiction between simple structure and high energy efficiency.
2Adaptability or versatility
If lighting device uses multiple LED chips with different wavelengths, then adaptability to environment improves, but device complexity increases
Solution Approach 1:
The lighting device achieves environmental adaptability by integrating multiple LED chips (blue, green, red) with different phosphor materials into a single multifunctional unit. The control circuit selectively activates specific LED-chip combinations based on the detected environmental color, allowing one device to perform multiple spectral functions. This approach provides high adaptability while avoiding the complexity of having separate lighting devices for different environments.
Solution Approach 2:
The system merges multiple LED chips with distinct wavelength characteristics and phosphor materials into a single integrated lighting module. The control circuit combines the output of these different light sources in varying proportions to match environmental colors. This merging strategy achieves high environmental adaptability while maintaining a compact, unified device structure rather than requiring multiple separate lighting devices.
3Illumination intensity
If lighting device emits high intensity light to overcome absorption, then brightness is sufficient, but power consumption increases
Solution Approach 1:
The system changes the spectral parameters of the emitted light by selectively activating different LED chips and adjusting their intensity ratios. Instead of uniformly increasing the intensity of all LEDs to overcome absorption, the control circuit optimizes the spectral composition to match the environmental reflectance characteristics. This parameter optimization achieves sufficient perceived brightness while minimizing power consumption by emitting only the necessary wavelengths at appropriate intensities.
