Existing visual media lighting systems face challenges in achieving high-quality, portable, and efficient soft lighting that can adapt to various physical space requirements and changing set conditions, particularly in terms of light quality and efficiency, which are not adequately met by current LED luminaires.
Innovation Solution
The development of LED light source edge-lit light guide panels with high flux, optical grade, and binned LEDs, along with modular and portable designs, remote phosphor LEDs, and advanced control systems, allows for flexible and efficient soft lighting solutions that can be easily set up and reconfigured to achieve desired lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If large incandescent lights with translucent silks or white boards are used to create soft base light, then soft lighting effect is achieved, but the system requires large footprint, much manpower, time, and supporting equipment
Solution Approach 1:
The patent divides the lighting system into modular LED panels that can be independently positioned and configured. Each panel contains multiple LED modules with diffusers, allowing the system to be segmented into manageable units rather than requiring large monolithic light sources with extensive supporting equipment.
Solution Approach 2:
The patent replaces the mechanical system of large incandescent lights with silks and white boards with an optical system using LED panels with integrated diffusers. This substitution eliminates the need for physical diffusing materials and complex mechanical arrangements, achieving soft light through optical design rather than mechanical construction.
2Illumination intensity
If large incandescent lights are used to create soft base light, then soft lighting effect is achieved, but significant amounts of power are consumed and air-conditioning is often required to cool stages
Solution Approach 1:
The patent changes the fundamental parameter of light source technology from incandescent to LED. This parameter change results in dramatically reduced power consumption and heat generation while maintaining the ability to produce soft lighting effects through optical design and diffuser integration.
3Use of energy by stationary object
If fluorescent lights are used to reduce power requirements, heat, footprint and weight, then energy efficiency is improved, but color temperature and color rendering characteristics do not meet visual media lighting expectations
Solution Approach 1:
The patent applies local quality by using individual LED modules with specific color temperatures and characteristics in different locations within the panel array. This allows optimization of color rendering in specific areas while maintaining overall energy efficiency, rather than relying on the uniform but inadequate color characteristics of fluorescent lights.
4Use of energy by stationary object
If current LED luminaires are used, then power consumption and heat generation are reduced, but light quality and efficiency do not satisfy visual media lighting professionals
Solution Approach 1:
The patent uses composite structures combining LED light sources with integrated diffusing materials and optical elements. This composite approach maintains the energy efficiency of LEDs while achieving the high light quality and uniformity required for visual media lighting, resolving the contradiction between energy efficiency and light quality.

AI summary
Improved soft lighting systems for the arts, media, and entertainment industry are disclosed. In certain aspects, the systems employ one or more edge-lit LED light guide panels using high flux, optical grade, and/or binned LEDs to produce higher quality, uniform, diffused soft visual media light. In further preferred aspects the systems are modular and portable, and have light guide panels that may be axially tilted in horizontal and vertical directions to independently direct the soft light emanating from each of the panels to achieve the desired soft lighting set up.
