Segmented Light Modules for Personalized Illuminance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems in open areas, such as offices or factories, struggle to provide personalized lighting for specific areas without affecting the illuminance of surrounding spaces, making it difficult for individuals to adjust lighting levels independently without disturbing others.
Innovation Solution
A lighting system comprising multiple independently adjustable light modules per source, where a controller selects and adjusts light modules based on position relationships and lighting distributions to tailor illuminance to specific areas, allowing for personalized lighting without affecting neighboring areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed light sources are used for general lighting in open areas, then the lighting system is simple and stable, but it is impossible to achieve personalized lighting for specific areas without affecting surrounding spaces
Solution Approach 1:
Each light source is divided into multiple independently controllable light modules, where each module can be selectively adjusted or turned off. This segmentation enables personalized lighting control for specific areas without affecting surrounding spaces, while maintaining the overall simplicity of the fixed light source structure.
Solution Approach 2:
The lighting system transitions from fixed, static light output to dynamically adjustable light modules. Each light module can be independently controlled to change its output level or be switched off, allowing the system to adapt to different personal lighting needs while maintaining structural stability.
2Adaptability or versatility
If additional lamps are used to enhance illuminance for a specific work place, then personalized lighting can be achieved, but the device complexity and energy consumption increase
Solution Approach 1:
Instead of adding external light sources, the existing light sources are segmented into multiple controllable modules. This allows energy to be concentrated on specific areas by activating only the necessary light modules, rather than illuminating the entire open area, thus reducing overall energy consumption while achieving personalized lighting.
Solution Approach 2:
The invention extracts and isolates the specific light modules needed for personalized lighting from the overall lighting system. By selecting and controlling only the relevant light modules rather than using additional lamps, the system achieves area-specific lighting control with reduced energy consumption.
3Adaptability or versatility
If multiple light modules are used per light source for directional control, then personalized lighting for target areas can be achieved, but the device complexity increases
Solution Approach 1:
Each light source is divided into multiple light modules with different lighting directions. This segmentation provides directional control capability for illuminating different areas, while the modular design allows for systematic management of the increased complexity through independent control of each module.
Solution Approach 2:
Different light modules within the same light source are designed with different lighting directions to suit different local requirements. This local quality approach allows each module to be optimized for its specific function while maintaining overall system coordination, managing complexity through functional differentiation.

AI summary
The present invention proposes a method, apparatus, controller and system for controlling illuminance. Specifically, the system comprises at least one light source, each of the at least one light source comprising a plurality of light modules and each of the plurality of light modules being adjustable independently; and a controller configured to control the illuminance of a target area in the lighting system. One or more light modules associated with the illuminance of the target area are selected from the at least one light source based on the position relationship between the at least one light source and the target area and a lighting distribution of each of the at least one light source. Then, at least one of the selected one or more light modules is adjusted to meet a certain requirement for the illuminance of the area. As a result, personalized lighting for an open area is effectively achieved.
