Sliding Effect Module for Stage Lighting Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stage lighting effect adjustment systems restrict the angular adjustment of stage lights due to the fixed position of the effect module, which prevents the effect sheet from switching into the light path at certain angles, limiting the range of light angle adjustment and resulting in incomplete stage effects.
Innovation Solution
A lighting effect adjustment system with a sliding effect module, where the effect module is independently slidable between the focusing and light output modules, allowing the effect sheet to be switched into the light path at any position, eliminating interference with the magnification module and enabling full-angle prism or frosting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the effect module is fixed on the focusing module, then the structure is simple, but the effect sheet blocks the magnification module when the gap is small, preventing stage effects from switching in at certain angles
Solution Approach 1:
The patent segments the effect module from the focusing module, making them independent movable units. The effect module can slide independently along the light path between the focusing module and light output module, allowing it to be positioned separately from the focusing module. This segmentation enables the effect sheet to switch in and out of the light path without being constrained by the focusing module's position, thus resolving the conflict between structural simplicity and light angle adjustment versatility.
Solution Approach 2:
The patent introduces dynamic positioning capability for both the effect module and magnification module along the light path. Both modules can be independently moved to adjust their positions, allowing the system to adapt to different lighting angles and effects. This dynamic arrangement replaces the fixed positioning, enabling the effect sheet to be properly positioned relative to the light path regardless of the magnification module's position, thereby expanding the light angle adjustment range.
2Ease of operation
If the effect sheet is switched in directly above the focusing lens, then the beam effect is achieved, but the effect sheet occupies the magnification module's motion space, shortening the angle adjustment range
Solution Approach 1:
The patent extends the positioning capability from a single fixed position (directly above the focusing lens) to a continuous range of positions along the light path. By allowing the effect module to slide independently between the focusing module and light output module, the system transforms the effect sheet positioning from a one-point solution to a multi-position solution, enabling effect sheet insertion at various locations depending on the magnification module's position and the desired lighting angle.
3Measurement precision
If the magnification module is moved close to the focusing module, then the angle adjustment is precise, but the effect sheet is blocked and cannot switch into the light path
Solution Approach 1:
The patent makes both the effect module and magnification module dynamically positionable along the light path. When the magnification module is moved close to the focusing module for precise angle adjustment, the effect module can independently slide to an appropriate position to ensure the effect sheet is not blocked and can switch into the light path. This dynamic independence resolves the conflict between achieving precise angle adjustment and maintaining effect sheet switching capability.
