Annular Gobo Segments for Compact Lighting Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lighting apparatuses face challenges in providing multiple light effects simultaneously due to spatial constraints, as each effect requires specific positioning of light forming elements within the optical system, limiting the ability to combine features like effect wheels and framing systems in projecting devices.
Innovation Solution
A light effect system that integrates a moving head lighting fixture with a light effect wheel comprising annular gobo segments and animation segments, allowing rotation and positioning within the light beam to create dynamic patterns, reducing spatial requirements and enabling combination of effects like animation and gobo patterns at the focal point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate light forming elements (effect wheel and framing system) are used to create different light effects, then the variety of light effects is improved, but the spatial requirements and device complexity increase
Solution Approach 1:
The patent combines the effect wheel and framing system into a single integrated unit where the effect wheel is positioned within the light beam path and framing blades are arranged around the same light source. This merging allows multiple light effects (animation, gobo patterns, framing) to be achieved from one compact assembly rather than requiring separate devices, thereby reducing spatial requirements while maintaining effect variety
Solution Approach 2:
The integrated light forming unit serves multiple functions simultaneously: the effect wheel creates animation and gobo effects when positioned in the light beam, while the framing blades provide framing effects around the same light source. This multi-functionality allows a single device to replace multiple separate light effect devices, reducing overall system complexity and space occupation
2Volume of moving object
If effect wheel and framing system are integrated into a single device, then space occupation is reduced, but the positioning precision and optical quality may deteriorate
Solution Approach 1:
The integrated unit is segmented into distinct functional components: the effect wheel with its rotation mechanism is separated from the framing blades, which are mounted on a separate rotation mechanism. This segmentation allows each component to be independently positioned and adjusted within the light beam path, ensuring that despite the compact integration, each element can achieve its required positioning precision without interfering with the other components
Solution Approach 2:
The effect wheel is positioned in the focal plane of the optical system where it can be precisely focused, while the framing blades are arranged in a different spatial dimension around the light source. This dimensional separation allows both components to coexist in the integrated unit without compromising their respective positioning precision or optical quality

AI summary
The present invention relates light forming means for modifying a light beam. The light forming means comprises a number of annular gobo segments arranged partially around the center of the light forming means and each of the annular gobo segments has an angular extent allowing the light beam to be enclosed by the annular gobo segment. The light forming means comprises also an annular animation segment forming an annular segment of the light forming means, wherein the angular extent of the animation segment is at least twice as big as the annular extent of at least one of the annular gobo segments. The present invention relates also to a light effect system and illumination device comprising such light forming means.
