Solution Overview
Problem
Traditional recording stage lighting systems using LED panels fail to accurately project the color spectrum, leading to inaccurate lighting and high costs, and often cause reflections and decreased contrast ratios due to diffusion materials.
Innovation Solution
A system comprising a support structure with multiple light sources, a perforated layer with a more reflective inward face and a less reflective outward face, and an optional diffusing layer, which adjusts light emission profiles based on background image data to provide accurate and efficient lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED panels are used to illuminate actors, then lighting coverage is improved, but color accuracy deteriorates and cost increases
Solution Approach 1:
The patent introduces a perforated layer as an intermediary component between the LED light sources and the actors. This layer with its specific aperture arrangement modifies the light spectrum to improve color accuracy while maintaining the broad coverage provided by the LED panels.
Solution Approach 2:
The perforated layer applies local quality modification by selectively allowing certain wavelengths of light to pass through its apertures while blocking others, thereby improving color accuracy in specific spectral regions without compromising overall illumination coverage.
2Illumination intensity
If LED panels are used to illuminate actors, then lighting coverage is improved, but cost increases
Solution Approach 1:
The perforated layer serves multiple functions simultaneously: it acts as a spectral filter for color accuracy, a diffuser for uniform lighting, and a cost-effective alternative to expensive specialized LED panels. This multi-functionality reduces overall system cost while maintaining performance.
Solution Approach 2:
The patent changes the parameters of the lighting system by introducing a perforated layer with specific aperture sizes and distributions, which modifies the light output characteristics to achieve better color accuracy and reduce costs compared to traditional LED panels.
3Stability of the object's composition
If diffusion materials are used to improve lighting, then uniformity is improved, but reflections and decreased contrast ratios occur
Solution Approach 1:
The perforated layer provides local quality control by creating controlled light paths through its apertures, which reduces unwanted reflections while maintaining uniformity. The specific aperture arrangement allows light to pass through in controlled directions, minimizing reflective harmful factors.
Solution Approach 2:
The patent converts the potentially harmful reflective properties of diffusion materials into a benefit by using the perforated layer's aperture structure to control light directions. The apertures are designed to allow light to pass through while blocking reflective paths that cause harmful effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides cost-effective, accurate lighting with improved contrast ratios and reduced reflections, allowing for precise illumination of specific stage areas while minimizing light wastage and enhancing image capture.
Implementation Method 1
The inward face of the perforated layer includes a surface layer that is more reflective than a surface layer of the outward face of the perforated layer
Implementation Method 2
an outer reflectance of the outward face of the perforated layer is less than 20% for the at least one wavelength of projected light
Implementation Method 3
the diffusing layer reflects at least a portion of projected light that is reflected from the inward face of the perforated layer

AI summary
The systems herein include a support structure and multiple light sources mounted to the support structure. The light sources are configured to project light onto a recording stage to light a specified video scene that is to be recorded on the recording stage. These systems also include a perforated layer that includes an arrangement of apertures. The perforated layer has an inward face directed toward the lighting sources and an outward face directed toward the recording stage. The inward face of the perforated layer includes a surface layer that is more reflective than the surface layer of the outward face of the perforated layer. These systems also include a controller that modifies the light emission profile of the light sources, including changing color balance, brightness, time dependence, and/or spatial variation over the light emissive surface of the light sources. Various other apparatuses and recording stage devices are also disclosed.
