Single Support Wheel Gobo Assembly for Compact Light Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projecting light fixtures face challenges in creating diverse light effects due to limited space and focal area capabilities, making it difficult to accommodate multiple beam shaping objects, which are essential for generating various light effects while maintaining a compact and easy-to-handle design.
Innovation Solution
A projecting light fixture with a single support wheel featuring multiple gobo wheels and a beam shaping plate, where each gobo wheel is rotatable to position its beam shaping object in the light beam, allowing for various light effects by blocking and shaping the light beam with both gobo and plate beam shaping objects, controlled by a unit to rotate the gobo wheels relative to the plate beam shaping objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple beam shaping objects are provided to create diverse light effects, then the variety of light effects is improved, but the space requirements and device complexity increase
Solution Approach 1:
The single support wheel serves multiple functions by carrying multiple gobo wheels, each with different beam shaping objects. The rotation mechanism allows any gobo wheel to be positioned in the light beam, enabling diverse light effects without requiring separate support structures for each gobo wheel, thus reducing overall device complexity while maintaining versatility
Solution Approach 2:
Multiple gobo wheels that would traditionally require separate support structures are merged onto a single support wheel. The beam shaping plate with multiple plate beam shaping objects is also integrated into the same focal plane area. This consolidation reduces the number of components and simplifies the overall device structure while preserving the ability to generate multiple light effects
2Adaptability or versatility
If multiple beam shaping objects are provided to create diverse light effects, then the variety of light effects is improved, but the space requirements increase
Solution Approach 1:
Instead of arranging multiple beam shaping objects in different spatial locations along the optical path (one-dimensional arrangement), the invention arranges them in the focal plane area where they can be selectively positioned through rotation. This dimensional change allows multiple objects to coexist in a compact area without interfering with each other's function, reducing the overall space requirements while maintaining the ability to generate diverse light effects
3Ease of operation
If the light fixture is made compact, then the ease of handling is improved, but the space available for multiple beam shaping objects is reduced
Solution Approach 1:
The invention uses rotation mechanisms to dynamically position different gobo wheels and plate beam shaping objects into the light beam as needed. This dynamic arrangement allows a compact fixture to accommodate multiple beam shaping objects by bringing them into the focal plane area only when required, rather than requiring all objects to be simultaneously accessible in static positions, thus maintaining both compactness and functionality

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the generation of a wide range of light effects with reduced space requirements, comparable to fixtures with two support wheels, allowing for dynamic and static light patterns, including Moiré effects, while maintaining a compact and user-friendly design.
Implementation Method 1
The at least one source light beam passing through one of the gobo wheels is at least partly blocked by the gobo beam shaping object of said one gobo wheel and the corresponding plate beam shaping object facing said one gobo wheel
Implementation Method 2
A control unit of the light fixture is configured to rotate each of the gobo wheels with its gobo beam shaping object relative to the beam shaping plate around the gobo wheel axis
Implementation Method 3
The single support wheel is rotatable around its support wheel axis such that one of the plurality of gobo wheels is placed with its gobo beam shaping object in the at least one source light beam
