Dome Gimbal Orchestral Light Fixture for Toolless Aiming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orchestra shell light fixtures are aesthetically unappealing due to yoke mounting, limited in functionality with fixed focus, and interfere with other equipment, generating heat and noise, making them uncomfortable for musicians.
Innovation Solution
A snag-free dome gimbal light fixture allowing rotation in three axes with tool-less adjustment, minimizing height to avoid equipment interference and providing comfortable, safe, and flexible lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light fixtures are yoke mounted to allow rotation, then functionality is improved, but aesthetic appearance deteriorates and interference with other equipment increases
Solution Approach 1:
The light fixture employs a dome gimbal mechanism that enables dynamic rotation and tilting movements while maintaining a compact, aesthetically pleasing form factor. The gimbal structure allows the light to pivot in multiple axes without requiring a bulky yoke mounting, thus achieving both functionality and aesthetic appeal.
Solution Approach 2:
The light fixture components are nested within a compact dome structure, where the gimbal mechanism is integrated inside the dome housing. This nesting approach minimizes the overall footprint and eliminates the need for external yoke mounting structures, thereby improving aesthetics while preserving rotational capabilities.
2Shape
If light fixtures are recessed to improve appearance, then aesthetic appearance is improved, but functionality is limited to fixed focus and profile size increases
Solution Approach 1:
The recessed light fixture incorporates a dome gimbal mechanism that provides dynamic adjustment capabilities including pan, tilt, and rotate movements. This dynamic structure allows the light to be positioned at various angles while remaining recessed into the shell, thus maintaining aesthetic appearance while achieving full functionality.
Solution Approach 2:
The fixture achieves three-dimensional adjustment capability (pan, tilt, rotate) within a recessed mounting configuration. By utilizing the dome gimbal's multi-axis rotation, the light can be positioned in multiple dimensions without protruding excessively, thus maintaining a clean aesthetic while providing versatile adjustment options.
3Volume of moving object
If light fixtures are made compact to reduce interference, then interference with equipment is reduced, but adjustment capability may be compromised
Solution Approach 1:
The dome gimbal mechanism incorporates tool-less adjustment features with hand-operated knobs that allow users to easily pan, tilt, and rotate the light fixture without requiring tools. The self-contained design integrates all adjustment mechanisms within the compact dome structure, making the small fixture easy to operate and adjust while maintaining its compact size.
4Illumination intensity
If traditional lights are used, then lighting function is provided, but heat generation makes musicians uncomfortable and noise from cooling fans is generated
Solution Approach 1:
The fixture transitions from traditional high-heat lighting sources to LED technology, fundamentally changing the thermal parameters of the light source. LEDs generate significantly less heat than traditional incandescent or halogen lights, thereby eliminating the discomfort for musicians while reducing or eliminating the need for cooling fans and associated noise.

AI summary
An innovative light fixture for use with acoustical shells is disclosed. The fixture incorporates a dome gimbal to allow rotation front-to-back and left-right around a horizontal axis and a third axis of rotation around a vertical axis. The dome configuration allows for a low profile and toolless adjustment allows stage side aiming by hand.
