Multi-Output Light Fixture with Segmented Emitters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures are one-dimensional and lack the flexibility to provide multiple light outputs tailored to specific needs, such as varying brightness and color temperature, which is essential in healthcare settings where different lighting modes are required for examinations, ambient lighting, and focused reading.
Innovation Solution
A light fixture system comprising a primary and secondary lighting unit, each with multiple light emitters and a lens, connected via a driver and communication network to provide independent and adjustable light outputs, allowing for flexible lighting solutions by converging light on a specific area and incorporating sensors and control components for occupancy and daylight adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional single-output light fixtures are used, then the device complexity is low, but the adaptability and versatility are insufficient for different lighting needs
Solution Approach 1:
The light fixture is divided into multiple independent light output sections, each with its own controllable light emitters and optical characteristics. This segmentation allows different zones to provide different lighting modes (ambient, task, accent) simultaneously, resolving the contradiction by making the fixture adaptable without requiring entirely separate fixtures for each function.
Solution Approach 2:
The light fixture is designed to perform multiple lighting functions within a single device structure. By integrating multiple light output sections with different controllable characteristics into one fixture, it achieves universal applicability for various lighting needs (reading, ambient, task lighting) without increasing the number of separate fixtures, thus managing complexity while enhancing versatility.
2Adaptability or versatility
If multiple light emitters with independent control are added, then the lighting flexibility and customization are improved, but the device complexity increases
Solution Approach 1:
The light fixture incorporates dynamically controllable light emitters that can adjust their output characteristics (intensity, color temperature, direction) in real-time. This dynamic control allows the fixture to adapt to different lighting scenarios on demand, providing flexibility without requiring permanent physical reconfiguration or overly complex mechanical systems.
Solution Approach 2:
The invention utilizes controllable light emitters whose electrical parameters (current, voltage, frequency) can be modified to change light output characteristics. By controlling electrical parameters rather than physical structure, the system achieves high flexibility in light output customization while keeping the physical device structure relatively simple and manageable.
3Productivity
If multiple light outputs are provided in a single fixture, then the productivity and functionality are enhanced, but the manufacturing complexity increases
Solution Approach 1:
The fixture is designed with modular segmented components that can be manufactured separately and assembled systematically. This segmentation allows for standardized manufacturing of individual light output sections, making the overall manufacturing process more manageable despite the enhanced functionality, thus resolving the contradiction between productivity enhancement and manufacturing ease.
4Adaptability or versatility
If conventional one-dimensional lighting is used, then the installation simplicity is maintained, but the functional versatility for specific applications is limited
Solution Approach 1:
Different sections of the light fixture are designed with locally optimized characteristics tailored to specific lighting functions (e.g., directional spotlights for task lighting, diffuse outputs for ambient lighting). This local quality approach allows each part of the fixture to excel at its specific function while the overall system remains integrated, providing application-specific versatility without requiring completely different fixtures for each application.

AI summary
A light fixture includes a housing having an upper wall, a first side wall, and a second side wall at least partially defining an interior and a bottom opening. A mounting tray is positioned in the interior and releasably connected to the housing. A first light emitter is connected to the mounting tray and has a first light output. A second light emitter is connected to the mounting tray and has a second light output. A third light emitter is connected to the mounting tray and has a third light output. A lens is connected to the housing. The light fixture can be optionally connected to a secondary light fixture and used to control light outputs from both fixtures.
