Transom Light Arrangement for Glare-Free Ceiling Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional illumination systems in internal spaces often create glare and uneven lighting, as artificial light sources are typically mounted in the ceiling or side walls, differing from natural light sources, which can lead to discomfort and inefficient use of light.
Innovation Solution
A transom light arrangement featuring a light source mounted on or in a transom, with a screen structure, directing light upwardly to illuminate a spatial region above the horizontal plane, avoiding glare and ensuring homogeneous ceiling illumination through adjustable emission angles and optical units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If artificial illumination is mounted in the ceiling or side walls, then the internal space can be illuminated, but glare and uneven lighting occur
Solution Approach 1:
The light source is repositioned from traditional ceiling or side wall locations to a transom window location, utilizing the upper horizontal plane dimension. Light is directed upward onto the ceiling surface, which then acts as a secondary diffuse light source, eliminating direct glare while providing homogeneous illumination throughout the space.
Solution Approach 2:
The ceiling surface serves as an intermediary element between the light source and the working plane. Light from the transom-mounted source illuminates the ceiling, which then diffuses the light downward, creating indirect illumination that avoids glare while maintaining even light distribution across the room.
2Illumination intensity
If light is directed upwardly to illuminate the ceiling, then homogeneous illumination is achieved, but light distribution control becomes complex
Solution Approach 1:
Optical units with varying emission angles are employed to control light distribution. By adjusting the emission angle parameter of the optical units, the system can adapt light distribution to different ceiling heights and room configurations without increasing overall system complexity, achieving homogeneous illumination through parameter optimization rather than structural complexity.
