Artificial Skylight Lighting System for Dynamic Indoor Emulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indoor environments, such as office spaces, often lack access to natural light, leading to a disconnection from the dynamic and varied lighting conditions found outdoors, which are essential for emotional and biological well-being, and conventional lighting systems fail to replicate the immersive and natural lighting experiences of outdoor environments.
Innovation Solution
A lighting system comprising an artificial skylight and functional general lighting devices, positioned in close proximity, with a controller that renders dynamic light scenes mimicking the temporal sequences of outdoor lighting conditions, including variations in intensity and color temperature, to create an immersive and natural lighting experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional static lighting devices are used in indoor environments, then the lighting system is simple and easy to control, but it cannot replicate the dynamic and varied lighting conditions of outdoor environments, leading to a disconnection from natural light cycles
Solution Approach 1:
The patent applies dynamics by replacing static lighting devices with dynamic lighting systems that can change their output over time. The lighting device includes a controller that adjusts the light output based on simulated outdoor light cycles, creating temporal variations in intensity and color temperature to replicate natural lighting conditions.
Solution Approach 2:
The patent utilizes parameter changes by varying multiple lighting parameters including intensity, color temperature, and temporal patterns. The controller adjusts these parameters to simulate different times of day, weather conditions, and seasonal variations, enabling the lighting system to adapt to different environmental contexts.
2Adaptability or versatility
If light transmitting structures such as skylights or windows are installed to increase daylight access, then the feeling of well-being is improved, but the installation cost increases and privacy and safety issues arise
Solution Approach 1:
The patent applies copying by creating an artificial representation of natural light conditions through a controllable lighting device. Instead of installing physical skylights or windows that expose occupants to external environmental factors, the system copies the essential characteristics of natural light (intensity, color temperature, temporal patterns) to provide similar benefits without the associated risks.
3Adaptability or versatility
If artificial skylights or displays showing natural elements are used, then the feeling of well-being may be improved, but they draw attention to the indoor environment and have the opposite effect
Solution Approach 1:
The patent applies local quality by providing immersive lighting experiences in specific localized areas rather than throughout the entire space. The lighting device creates focused zones of natural light simulation that can be activated as needed, allowing occupants to experience natural lighting conditions without being constantly reminded of the artificial environment.

AI summary
A lighting system comprises a lighting arrangement (153) and a controller for controlling the lighting arrangement. The lighting arrangement comprises an artificial skylight (161-163) and a functional general lighting device (166,168) for providing horizontal light. The functional general lighting device comprises a horizontal luminous surface. The functional general lighting device is positioned in parallel and adjacent to the artificial skylight. A spacing between the functional general lighting device and the artificial skylight does not exceed the width of the artificial skylight. The controller is configured to control the artificial skylight and the functional general lighting device to render different light effects of a dynamic light scene. The dynamic light scene specifies a temporal sequence of light effects for each of a plurality of lighting devices, including the artificial skylight and the functional general lighting device.
