Illumination Device with Independently Movable Diffractor Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing entertainment lighting systems, such as moving head light fixtures, are limited in creating independent and adjustable light beams, as they often produce twin beams with dependent characteristics like intensity, color, divergence, and size, which cannot be controlled independently.
Innovation Solution
An illumination device featuring a light source and a light beam diffractor with independently movable diffractor sections, allowing for the creation of two independently controlled light beams that can be combined or separated, enabling new light effects and zoom techniques by rotating and positioning the diffractor sections relative to the light beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light source with a prism apparatus is used to create twin beams, then two light beams can be generated, but the characteristics (intensity, color, divergence, size) of the twin beams cannot be controlled independently
Solution Approach 1:
The light beam diffractor is divided into a first diffractor section and a second diffractor section that can be moved independently relative to the light beam. Each section processes a portion of the light beam separately, enabling independent control of beam characteristics such as direction, size, and divergence for each resulting beam while maintaining a relatively simple overall structure.
2Ease of operation
If diffractor sections are made movable to enable independent beam control, then beam direction and size can be adjusted, but the device complexity increases
Solution Approach 1:
The diffractor sections are made movable relative to the light beam, allowing dynamic adjustment of beam characteristics. The first and second diffractor sections can be positioned at different locations and angles to independently control beam direction, size, and divergence, providing operational flexibility without requiring overly complex mechanisms.
