1Illumination intensity
If manual adjustments are used to optimize lighting spectrum for different scenes and objects, then lighting quality can be optimized, but the system becomes impractical for varying conditions
Solution Approach 1:
The lighting system automatically senses scene characteristics using an integrated sensor and autonomously adjusts the lighting spectrum without requiring manual user input. The controller processes sensor data and modifies light output parameters based on detected scene properties, enabling the system to serve itself and adapt to varying conditions automatically.
Solution Approach 2:
The system incorporates a sensor that continuously monitors scene characteristics and feeds this information back to the controller. The controller uses this feedback to dynamically adjust the lighting spectrum, creating a closed-loop control system that optimizes illumination quality based on real-time scene conditions without manual intervention.
2Adaptability or versatility
If multiple light sources are used to illuminate a scene, then lighting coverage and flexibility improve, but system complexity increases
Solution Approach 1:
The patent combines multiple light sources with different spectral characteristics into a single integrated lighting system. By merging LED modules with distinct emission spectra (e.g., warm white, cool white, colored LEDs) under one control architecture, the system achieves versatile lighting coverage while managing complexity through unified control of the combined light sources.
Solution Approach 2:
The lighting system is designed with multi-functional light sources that can perform multiple roles. The same LED modules used for illumination also serve as sensing references, and the controller handles both sensing coordination and lighting control functions, reducing overall system complexity while maintaining adaptability across different lighting scenarios.
