Solution Overview
Problem
Existing electrically operated optical display devices for creating artificial sky light lack dynamic realism and fail to accurately replicate the colors and intensity of a real-life sky, leading to a less immersive experience.
Innovation Solution
The system incorporates a diffuse light generation system and a collimated light generation system, controlled by electrical circuitry that determines the color and intensity of a real-life sky to create a more realistic virtual sky scene, using a determination system that can adaptively sense and replicate the color, intensity, and angle of the real-life sky light and sun light components in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a static artificial sky light is used, then the device structure is simple, but the dynamic realism and accuracy of color reproduction are poor
Solution Approach 1:
The patent implements dynamic adjustment of light color temperature and intensity through electrical circuitry that receives real-time sky condition data and modifies the output light characteristics accordingly. This allows the artificial sky light to adapt to changing environmental conditions, improving color accuracy and realism while managing system complexity through programmed control rather than mechanical complexity
Solution Approach 2:
The determination system measures actual sky light characteristics and feeds this information back to the optical display device, which then adjusts its output to match the measured conditions. This closed-loop feedback mechanism enables precise color and intensity reproduction of real-time sky conditions, resolving the contradiction between simplicity and accuracy
2Adaptability or versatility
If the device replicates real-time sky conditions, then the realism is improved, but the response time and adaptability are reduced
Solution Approach 1:
The determination system continuously monitors sky conditions and pre-processes the data to determine appropriate light output parameters before significant changes occur. This preliminary detection and processing enables the system to respond proactively to changing sky conditions, reducing perceived response time while maintaining accurate adaptation to real-time environmental variations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a highly realistic virtual sky scene with uniform color and intensity, closely mimicking the appearance of a real sky, enhancing the immersive experience and reducing inconsistencies between the artificial and natural sky views.
Implementation Method 1
A portion of the collimated light beam is scattered by the diffuse light generator by Rayleigh scattering as blue, diffuse light to provide an artificial skylight component
