Solution Overview
Problem
Stage light fixtures emit a light beam with decreasing luminosity as the projection distance increases, and existing technologies cannot adjust luminosity or quality effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the beam is projected at a long distance, then the projection range is improved, but the luminosity decreases
Solution Approach 1:
The first optical assembly is positioned upstream of the diaphragm to preliminarily enlarge or concentrate the light beam before it reaches the diaphragm. This preliminary action optimizes the beam characteristics at the source, allowing the beam to maintain higher luminosity over longer projection distances by pre-adjusting its concentration uniformity
Solution Approach 2:
The system changes the concentration uniformity parameter of the light beam by adjusting the first optical assembly. This parameter change allows the beam to be selectively enlarged or concentrated, optimizing luminosity distribution to maintain intensity at long projection distances while expanding the beam's reach
2Illumination intensity
If the first optical assembly is added to optimize luminosity, then the beam quality is improved, but the device complexity increases
Solution Approach 1:
The first optical assembly positioned upstream of the diaphragm serves multiple functions: it enlarges the beam, concentrates the beam, and optimizes concentration uniformity. This multi-functionality allows a single component to achieve multiple optical optimization goals without proportionally increasing system complexity
Solution Approach 2:
The first optical assembly acts as an intermediary element between the light source and the diaphragm. It mediates the beam characteristics by selectively enlarging or concentrating the light before it reaches the diaphragm, optimizing luminosity and quality without requiring complex modifications to the existing light source or diaphragm structures
