Stage Lighting Accessory Tubular Element Omnidirectional Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stage lighting fixtures with multi-source solid-state sources primarily generate visible effects only when observed frontally, and animations or graphics are not visible from the side, and cannot be displayed when no light beam is projected, limiting the creation of innovative scenic effects.
Innovation Solution
An accessory for stage lighting fixtures comprising a hollow tubular element with a light emission surface that can be coupled to the head of the light fixture, allowing for additional degrees of freedom in managing scenic effects, enabling effects to be seen from all angles, including when no light beam is projected, through independently controllable light modules and strategically placed through openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light fixture uses multi-source solid state sources to generate projected beams, then the light intensity and beam projection capability are improved, but the visibility of graphic effects and animations is limited to frontal observers only
Solution Approach 1:
The invention divides the light emission function into two separate components: the original light fixture head for beam projection and the added tubular accessory for omnidirectional graphic effects. This segmentation allows each component to specialize - the head maintains high-intensity beam projection while the tube provides 360-degree visible animations, resolving the contradiction between beam intensity and multi-angle visibility
Solution Approach 2:
The invention transitions from two-dimensional frontal display to three-dimensional omnidirectional display by adding the tubular element that emits light in all radial directions. This dimensional change allows graphic effects to be visible from any angle around the fixture, not just from the front, thereby improving adaptability while maintaining beam projection capability
2Object-affected harmful factors
If the projector is switched off to avoid projecting light beams, then the harmful light beam projection is eliminated, but the graphics and animations become invisible even to frontal observers
Solution Approach 1:
The invention merges the tubular accessory with independent light emission capability to the light fixture head. This combination allows the system to operate in multiple modes: the tube can provide visible animations independently when the beam projector is off, or both can operate together. The tube's light emission surface ensures graphics remain visible from all angles regardless of beam projection state, eliminating the harmful effect while preserving visual output
Solution Approach 2:
The tubular element acts as an intermediary light emission component that bridges the gap between beam projection and graphic display functions. It can independently generate visible animations through its light emission surface without requiring the main projector to be active, serving as a mediator that maintains visual output while avoiding unwanted beam projection
3Adaptability or versatility
If the light fixture is designed to produce animations surrounding the scene when switched off, then the scenic versatility is improved, but the device complexity increases
Solution Approach 1:
The tubular accessory is designed with multi-functionality: it can emit light for graphic effects in all directions, it can be controlled independently from the beam projector, and it can operate in multiple modes (alone or with the beam). This universal design achieves high scenic versatility without requiring complex integration, as the tube is a relatively simple additive component that enhances functionality while maintaining structural simplicity

Function Achieved in This Case
