Multi-lamp Stage Light with Independent Rotation and Wiring Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stage lighting fixtures can only produce single lighting effects and have limited directional capabilities, restricting their ability to achieve variable and omnidirectional lighting effects, as they typically consist of a single light source that can only project light in one direction or rotate around a fixed axis.
Innovation Solution
A multi-lamp stage light with a base, support frame, and lamp units connected via multiple rotation shaft mechanisms, allowing each lamp unit to be driven independently by its corresponding driving apparatus, enabling simultaneous or differential rotation around different axes, and featuring a U-shaped support frame with notches and containing chambers for omnidirectional light projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light source is used in a stage lighting fixture, then the structure is simple, but only a single lighting effect can be produced and light can only be projected in one direction
Solution Approach 1:
The lighting fixture is divided into multiple independent lamp units, each with its own light source and control. This segmentation allows each lamp unit to be independently controlled to produce different lighting effects and directions, thereby achieving diverse lighting effects without requiring complex optical elements for each effect.
Solution Approach 2:
The patent introduces rotational freedom for lamp units around a central axis, adding a dimensional aspect to light projection. By enabling lamp units to rotate and project light in multiple directions (not just fixed directions), the system achieves omnidirectional lighting capability, effectively adding spatial dimensionality to the lighting effects.
2Adaptability or versatility
If multiple lamp units are provided with independent driving apparatus, then each lamp unit can be controlled individually for omnidirectional projection, but the device complexity and control line management become challenging
Solution Approach 1:
Multiple control lines for different lamp units are merged and routed through a common hollow rotating shaft structure. This consolidation allows control lines to share a common pathway, simplifying the overall control system architecture and reducing the complexity of managing multiple independent control routes while still enabling individual lamp control.
Solution Approach 2:
The hollow rotating shaft acts as an intermediary structure that facilitates the passage of control lines from the stationary base to the rotating lamp units. This intermediary mechanism enables control signals to be transmitted to individually controllable lamp units without creating tangled control lines, as the shaft provides a structured, organized pathway for all control connections.
