Pyramid UV IR Filter Redirects Heat in Stage Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stage lighting systems face inefficiencies as they produce significant heat alongside light, with previous solutions failing to effectively redirect non-visible UV/IR energy away from the light source, causing it to be reflected back and requiring additional space and heat management.
Innovation Solution
A pyramid-shaped radiation filter is angled relative to the light beam's axis, and a two-dimensional wedge or cone-shaped filter using glass pieces redirect non-visible light energy into different directions, preventing it from returning to the light source and isolating heat from optical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a UV/IR filter is used to reject non-visible light, then the light output is cleansed of non-visible components, but the rejected energy passes back to the lamp causing heat management issues
Solution Approach 1:
The patent converts the harmful reflected energy back to a beneficial direction by using a reflective surface positioned at a specific angle. The energy that would normally be rejected and cause heat problems is instead reflected away from the lamp housing, converting a harmful effect into a safe redirection of energy flow.
Solution Approach 2:
The patent introduces an intermediary reflective surface between the filter and the lamp housing. This intermediary element intercepts the rejected energy and redirects it away from the lamp, preventing direct exposure while maintaining the filtering function.
2Object-affected harmful factors
If an angled filter is used to redirect energy away from the lamp, then heat exposure is reduced, but the device requires more space and additional heat management infrastructure
Solution Approach 1:
The patent merges the filtering function and the energy redirection function into a single integrated component. The filter is positioned and angled to simultaneously perform wavelength selection and energy redirection, eliminating the need for separate components and reducing overall device complexity.
Solution Approach 2:
The patent uses angular positioning in a different dimensional orientation to achieve energy redirection. By adjusting the angle of the filter relative to the lamp axis, the system redirects energy in a spatial dimension that avoids the lamp housing without requiring additional linear space or complex infrastructure.
3Productivity
If a pyramid-shaped filter is used to reflect light in multiple directions, then energy is divided into different directions, but the filter becomes more complex in structure
Solution Approach 1:
The patent segments the filter into multiple reflective surfaces arranged in a pyramid shape, with each surface responsible for reflecting energy in a specific direction. This segmentation allows efficient energy distribution while maintaining a relatively simple structure based on basic geometric planes.
Solution Approach 2:
The patent employs an asymmetric pyramid shape rather than a symmetric design, allowing different facets to reflect energy in optimized directions based on the specific lighting requirements. This asymmetric configuration improves energy distribution efficiency while avoiding the complexity of highly symmetric multi-component systems.
