Ceiling Spotlight System for Flexible Workplace Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems for workplaces, such as ceiling lights and floor lamps, are inflexible and impractical for regularly changing work environments, as they require reconfiguration or reinstallation, which can be undesirable and inefficient.
Innovation Solution
A light emitter system that generates a stream of visible light on a ceiling, using an LED light source and optics to create a homogeneous luminance pattern, allowing for flexible and adaptive illumination of workspaces without the need for physical reconfiguration, and can be used on ceilings that are not suitable for traditional light installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ceiling lights are used to illuminate workplaces, then illumination of workstations is achieved, but flexibility is reduced as they require rehung, realigned and configured for regularly changing workplaces
Solution Approach 1:
The lighting system uses movable and adjustable light emitters that can be dynamically repositioned and reoriented to illuminate different workplaces. The system transitions from static ceiling fixtures to dynamic, reconfigurable lighting units that adapt to changing workspace arrangements without requiring permanent installation or complex reconfiguration.
Solution Approach 2:
The light emitters are designed as universal units that can serve multiple workplaces and functions. Each emitter can be positioned and oriented to illuminate different areas, making the lighting system versatile for various workplace configurations and eliminating the need for dedicated lighting fixtures for each specific workspace.
2Illumination intensity
If floor lamps are used to illuminate individual workplaces, then good illumination of individual workplaces is achieved, but room usability is impaired and they are perceived as annoying
Solution Approach 1:
The system transitions from horizontal placement of floor lamps to vertical suspension of light emitters from the ceiling. This dimensional change allows the lighting units to be positioned above workplaces without occupying floor space, thereby maintaining room usability while providing focused illumination. The light emitters hang in the vertical dimension, eliminating the need for floor-standing fixtures.
3Ease of operation
If ceiling lights are used to illuminate workplaces, then workplaces can be illuminated and lights are relatively unobtrusive, but flexibility is reduced as they have to be rehung, realigned and configured
Solution Approach 1:
The lighting system uses movable and adjustable light emitters that can be dynamically repositioned and reoriented to illuminate different workplaces. The system transitions from static ceiling fixtures to dynamic, reconfigurable lighting units that adapt to changing workspace arrangements without requiring permanent installation or complex reconfiguration.
4Reliability
If traditional light installations are used, then stable illumination is achieved, but structural support requirements increase and maintenance becomes more difficult
Solution Approach 1:
The system replaces heavy mechanical ceiling installations with lighter, suspended light emitters that can be supported by simpler structures. The light emitters are designed to be hung from the ceiling using minimal structural support, eliminating the need for complex mounting mechanisms while maintaining stable illumination through controlled positioning and orientation.
