Solution Overview
Problem
Existing lighting techniques and air conditioning systems with integrated lighting functions fail to provide a natural view that simulates changes in sunlight due to wind or time, and they do not effectively integrate air circulation and lighting for the purpose of enhancing spatial perception.
Innovation Solution
The proposed solution involves an air conditioner and lighting device configuration that includes a housing with an inlet, outlet, and illumination opening, a blower in the airflow path, a first light source, a light emitter with a light incident portion and a first light emission portion simulating natural light, and at least one light extractor that emits secondary light towards the space outside the housing, all of which are integrated with a control system to manage light emission states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a lighting device emits light simulating a sky to improve spaciousness, then the spaciousness of the space is improved, but the naturalness of the view is insufficient
Solution Approach 1:
The lighting device is divided into multiple light sources with different functions: a first light source for sky simulation, a second light source for sunlight simulation, and extractors for directional light emission. This segmentation allows each component to contribute to different aspects of naturalness while maintaining overall spaciousness.
Solution Approach 2:
Different regions of the lighting device emit different types of light with specific characteristics. The extractor emits light in specific directions to simulate sunlight angles, while other regions provide diffuse sky simulation. This local differentiation enhances the naturalness of the view without compromising the overall spacious effect.
2Adaptability or versatility
If air circulation and lighting functions are integrated, then device functionality is improved, but the ability to simulate natural light changes is insufficient
Solution Approach 1:
The lighting device dynamically adjusts light emission characteristics based on operational modes. The controller switches between different light sources and emission patterns to simulate natural light changes associated with different air circulation conditions, enhancing both functionality and naturalness.
Solution Approach 2:
The integrated device performs multiple functions: air circulation, sky simulation, sunlight simulation, and directional lighting. The light extractor serves both air circulation purposes and directional light emission, demonstrating multi-functionality that enhances natural light simulation capability.
3Reliability
If light extractors are provided around the light emitter, then natural light simulation is improved, but device complexity increases
Solution Approach 1:
The light extractor is integrated with the air circulation system, merging lighting functionality with existing structural components. This combining approach reduces overall device complexity by eliminating separate lighting structures while maintaining natural light simulation capability.
