Medical Lighting Device with Movable Frame for Monitor Reflection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lighting devices for medical treatment rooms, such as operating theatres, create issues with reflections on monitors due to bright illumination, compromising the view of medical personnel using endoscopic cameras and other modern medical equipment.
Innovation Solution
A lighting device with a support frame that can be moved to switch between direct and indirect illumination units, allowing medical professionals to adjust lighting conditions manually to suit the needs of different procedures, using a controller to activate or deactivate the illumination units based on the position of the support frame relative to the operating area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple lamps shine on the operating area at different angles to enhance illumination, then the illumination intensity is improved, but reflections on monitor screens increase and compromise the viewing of images
Solution Approach 1:
The lighting device is divided into multiple independent illumination units (first illumination unit with direct lighting, second illumination unit with indirect lighting) that can be selectively activated. This segmentation allows different lighting modes to be used for different surgical scenarios, resolving the contradiction between needing bright illumination and avoiding screen reflections.
Solution Approach 2:
The support frame is designed to be movable relative to the operating area, and its position automatically triggers switching between different illumination units. This dynamic adaptation allows the lighting system to respond to changing surgical needs, providing direct illumination when bright lighting is required and indirect illumination when monitor viewing is prioritized.
2Illumination intensity
If bright illumination is provided to illuminate the operating area, then the visibility of the surgical procedure is improved, but the viewing of images on monitors is compromised
Solution Approach 1:
The first illumination unit provides localized direct illumination focused on the operating area, while the second illumination unit provides diffuse indirect illumination that reduces screen reflections. This local quality differentiation allows the system to provide bright lighting where needed without compromising overall monitor viewing quality.
Solution Approach 2:
The system changes the lighting parameters by switching between direct and indirect illumination modes. The movable support frame triggers parameter changes in illumination type based on surgical needs, allowing transition from high-brightness direct lighting to lower-reflection indirect lighting.
3Stability of the object's composition
If a fixed lighting device is installed on the ceiling, then the installation stability is improved, but the ability to adjust lighting conditions for different procedures is reduced
Solution Approach 1:
The support frame is designed with movable components that allow the illumination units to be repositioned relative to the operating area. This dynamic capability enables adjustment of lighting conditions for different surgical procedures while maintaining stable installation through the fixed mounting structure.
Solution Approach 2:
The lighting device incorporates multiple illumination units with different lighting characteristics (direct and indirect) that can be selectively used for different surgical scenarios. This multi-functionality allows a single fixed installation to adapt to various lighting requirements across different procedures.

AI summary
The present invention provides a lighting device (1) for a medical treatment room, comprising: a support frame (2) configured to be mounted to a wall or to a ceiling of the medical treatment room; a first illumination unit (8) provided on the support frame (2) and configured to provide direct illumination of an operating area (O) in the treatment room; and a second illumination unit (10) provided on the support frame (2) and configured to provide indirect illumination of the operating area (O). The support frame (2) is articulated for movement of the first and second illumination units (8, 10) relative to the operating area (O). The lighting device is characterised in that movement of the support frame (2) is adapted to activate and deactivate the first and second illumination units (8, 10). Thus, the lighting device (1) includes a control unit configured to switch the first and second illumination units (8, 10) on and/or off when the support frame (2) is moved relative to the operating area (O).
