Light Effect System Radial Actuation for Compact Multi-Effect Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lighting apparatuses face challenges in providing multiple effects simultaneously due to spatial constraints, as typical optical systems can only focus on a limited area, making it difficult to integrate both effect wheels and framing systems effectively.
Innovation Solution
A light effect system that allows multiple light forming means to be positioned in the same plane, with each element capable of radial movement into and out of the light beam and continuous rotation around a rotational point outside the beam, preventing overlap and enabling more effects without increasing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light forming means are integrated into the same system to provide multiple effects, then the versatility and effect options are improved, but the spatial requirements and device complexity increase
Solution Approach 1:
The patent combines multiple light forming means (effect wheels, framing systems, gobos) into a single integrated system that shares common optical paths and mechanical support structures. This merging approach allows multiple effects to be achieved within one fixture rather than requiring separate fixtures for each effect type.
Solution Approach 2:
The light forming means are designed with multi-functionality, where each component can serve multiple purposes. For example, the system can switch between creating framed light beams, animated patterns, and gobo projections using the same basic optical infrastructure, reducing the need for dedicated components for each effect.
2Volume of moving object
If multiple light forming means are positioned in the same plane to enable integration, then the space requirements are reduced, but the risk of overlap and interference between elements increases
Solution Approach 1:
The light forming means are designed to move dynamically within the same plane rather than being fixed in static positions. Effect wheels can rotate in and out of the optical path, framing blades can open and close, and gobos can be inserted or removed. This dynamic positioning allows elements to share space without permanent overlap or interference.
Solution Approach 2:
While multiple light forming means are positioned in the same plane, they utilize additional dimensional freedom through rotation and angular movement. Elements can pivot around rotational points outside the beam path, allowing them to enter and exit the optical path without colliding with other components, effectively using rotational dimension to resolve spatial conflicts.
3Reliability
If light forming means rotate around a rotational point outside the light beam, then the beam path is kept clear and overlap is prevented, but the mechanical complexity of the rotation mechanism increases
Solution Approach 1:
The rotational points for the light forming means are positioned outside the light beam path, effectively extracting the mechanical rotation centers from the optical path. This separation allows the beam to travel through clear space while the mechanical complexity is confined to external mounting structures, reducing interference between optical and mechanical systems.
4Adaptability or versatility
If effect wheels and framing systems are integrated into the same optical system, then the number of effects is increased, but the focusing capability is compromised due to limited focal area
Solution Approach 1:
The optical system is designed with dynamic focusing capabilities that can adjust between different focal points depending on which light forming means is active. The system can shift focus to accommodate effect wheels at different positions in the optical path, maintaining sharp images whether framing blades are open or closed, or whether gobos are inserted or removed.

AI summary
The present invention relates to a light effect system for forming a light beam. The light effect system comprises a first light forming means adapted to form at least a part of the light beam where at least a first actuator is adapted to rotate the first light forming means around a first rotational point and around an first axis substantially parallel to the central axis of the light beam. At least a second actuator is adapted to move the first light forming means in relation to the light beam, such that first rotational point is moved in an area outside the light beam and radially in relation to the central axis of the light beam.
