False Window Unit Simulating Sunlight Directionality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional false window units lack the ability to enhance the perception of reality by accurately simulating the experience of natural sunlight and its directional changes, leading to a less immersive experience.
Innovation Solution
A false window unit comprising a window frame, an image display device, a light source that simulates sunlight, and a light-blocking member, which together create a realistic simulation of outdoor landscapes and sunlight patterns by adjusting light intensity and color temperature based on captured shooting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source emits light simulating sunlight through the window frame opening, then the perception of reality is enhanced, but the light becomes too uniform and lacks the directional characteristics of natural sunlight
Solution Approach 1:
The light source is divided into multiple independent light emitting units arranged at different positions and angles. Each unit can be controlled independently to simulate the directional characteristics of natural sunlight, resolving the contradiction between providing sufficient illumination and maintaining proper light directionality.
Solution Approach 2:
Different regions of the light source emit light with different characteristics (intensity, angle, color temperature) to match the local quality of natural sunlight at different positions in the window. This creates realistic directional light patterns while maintaining overall illumination effectiveness.
2Illumination intensity
If the light source emits light in all directions to maximize illumination, then the indoor space is well-lit, but the realistic simulation of sunlight is compromised
Solution Approach 1:
The light emitting units are configured to dynamically adjust their illumination patterns, switching between wide-angle and directional modes. This allows the system to provide comprehensive indoor lighting coverage while maintaining accurate sunlight simulation characteristics when needed.
Solution Approach 2:
The light source simulates the periodic movement and changing intensity of natural sunlight throughout the day. Different light units are activated in sequences that mimic sunrise, noon, and sunset patterns, providing both adequate illumination and realistic sunlight simulation at different times.
