Multiple Focus Point Light Relay Lens Optical Train
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stage lights typically have only a single focus location, limiting their ability to project multiple effects with both gobos and color wheels in focus simultaneously, which results in out-of-focus issues and reduced visual quality.
Innovation Solution
A stage light system with multiple focus points and image planes, utilizing a movable relay lens to relay images between planes, allowing multiple optical elements such as gobos and color wheels to be precisely in focus, and incorporating a motorized control system for precise positioning and integration of effects within the optical train.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single focus location is used in stage lights, then the device complexity is reduced, but the visual quality and ability to project multiple effects in focus deteriorates
Solution Approach 1:
The patent divides the single focus location into multiple focus locations (first focus location and second focus location) along the optical path. This allows different optical elements (gobo and color wheel) to be positioned at different focus locations, enabling both to be in focus simultaneously when projected, thereby resolving the contradiction between device complexity and visual quality.
2Manufacturing precision
If multiple optical elements are positioned at different focus locations, then the ability to project multiple effects in focus is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a relay lens system as an intermediary component between the first and second focus locations. The relay lens receives light from the first focus location and projects it to the second focus location, enabling precise positioning of multiple optical elements at different focal planes while managing the complexity through a well-defined optical intermediary.
3Manufacturing precision
If gobos and color wheels are both in focus, then the visual effects quality is enhanced, but out-of-focus issues and moire patterns occur when only single focus is available
Solution Approach 1:
The patent segments the optical path into distinct focus locations, placing the gobo at the first focus location and the color wheel at the second focus location. This spatial segmentation allows both elements to be precisely in focus simultaneously, eliminating the out-of-focus conditions that cause moire and aliasing artifacts in single-focus systems.

AI summary
A lamp unit with a relay lens that allows two different focus points. Two different optical altering elements are hence simultaneously in focus. The elements can be taken in and out of focus to allow different effects.
