Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light devices for stage and architectural lighting lack the ability to produce varied and dynamic light effects with ease, often requiring complex systems for fine adjustments and limited flexibility in beam orientation and aperture.
Innovation Solution
A wide-aperture light device with a reflector system surrounding the emitter system, allowing for relative displacement between the two, enabling modification of the light beam's trajectory and aperture angle, and featuring a drive mechanism for precise control of the reflector system's position, which can be actuated by a screw and nut or rack and pinion system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex system with multiple mirrors and adjustable components is used to achieve varied light effects, then the adaptability and versatility of light effects are improved, but the device complexity increases
Solution Approach 1:
The reflector system is divided into multiple independent reflective surfaces (first reflector, second reflector, third reflector) that can be adjusted separately. Each reflector can be positioned and oriented independently to create different light beam configurations, allowing varied light effects without requiring a completely complex integrated system.
Solution Approach 2:
The patent employs movable and adjustable reflectors that can be repositioned along optical paths and rotated to different angles. The first reflector can move along the first optical path, the second reflector along the second optical path, and the third reflector is adjustable in orientation. This dynamic adjustability enables a wide range of light effects while maintaining relatively simple individual components.
2Adaptability or versatility
If multiple reflectors and optical components are arranged to create varied beam orientations, then the adaptability of beam direction is improved, but the ease of operation deteriorates
Solution Approach 1:
The optical system is segmented into distinct reflector components (first, second, and third reflectors) with independent adjustment mechanisms. This segmentation allows each reflector to be optimized for specific functions while maintaining independent controllability, making the overall system easier to operate through modular adjustment rather than requiring complex coordinated control of a single integrated system.
3Device complexity
If a fixed reflector system is used to maintain structural simplicity, then the device complexity is reduced, but the adaptability of light effects deteriorates
Solution Approach 1:
The patent transforms a potentially fixed reflector system into a dynamic one by introducing movable and adjustable reflectors. The first reflector can translate along its optical path, the second reflector can move along its path, and the third reflector can be rotated. These dynamic capabilities enable the simple reflector structures to adapt to various light effect requirements without increasing overall system complexity significantly.
Solution Approach 2:
The reflector system is designed with multi-functional capability through the arrangement of multiple reflectors that can be adjusted to perform different functions. The same basic reflector components can create various beam orientations, apertures, and light patterns by changing their positions and angles, making the system universally applicable to different lighting effects without requiring specialized components for each effect.
