Low-glare Lighting Device with Hidden Light Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems, such as ceiling spotlights, cause glare and discomfort by projecting direct light that exceeds room luminance, making environments less pleasant for observers.
Innovation Solution
A device with translucent body and hidden lighting units that emit light indirectly through the body, providing soft, pleasant illumination without direct lines of sight to the light sources, ensuring the luminance ratio of the device to the room luminance is less than or equal to one.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If direct lighting is used to illuminate a room, then the illumination intensity is high, but the observer is dazzled by the light source exceeding room luminance
Solution Approach 1:
The patent introduces a translucent body as an intermediary between the light source and the observer. The light source illuminates the translucent body, which then diffuses the light to illuminate the room. This mediator prevents direct line of sight between the observer and the light source, eliminating glare while maintaining high illumination intensity through the diffused light.
Solution Approach 2:
The patent extracts the light source from direct view by placing it inside or behind the translucent body. The light source is separated from the observer's direct line of sight, allowing the illumination function to be maintained while the harmful glare effect is removed by taking out the light source from the observer's direct perception.
2Object-affected harmful factors
If the light source is hidden to eliminate glare, then the glare is reduced, but the lighting device complexity increases
Solution Approach 1:
The patent merges the light source with the translucent body by placing the light source inside or directly behind the translucent body. This combination creates a unified structure where the light source and the diffusing element work together as one integrated component, simplifying the overall device while achieving hidden light source functionality.
Solution Approach 2:
The translucent body serves multiple functions simultaneously: it acts as a diffuser to eliminate glare, as a housing to contain the light source, and as a structural element of the lighting device. This multi-functionality reduces the need for separate components, thereby reducing device complexity while achieving the hidden light source effect.
