Illuminated Panel With Adjustable LED And Diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting fixtures fail to replicate the benefits of natural sunlight, limiting its availability to only certain occupants in a building, as traditional windows and skylights are restricted to exterior walls and ceilings, and existing LED systems do not effectively mimic the appearance or adjustability of natural lighting.
Innovation Solution
A system comprising a frame with a light source, diffuser, and front panel, utilizing white or multi-colored LEDs with adjustable power circuitry to create a uniform and depth-appearing light, resembling windows or skylights, with options for adjustable CCT and CRI, and a shroud to enhance the traditional appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional windows and skylights are used to admit sunlight, then natural lighting benefits are achieved, but exterior access is required which limits availability to certain occupants only
Solution Approach 1:
The patent uses LED light sources with adjustable CCT and CRI to copy the spectral characteristics of natural sunlight, creating artificial light that mimics the benefits of daylight without requiring actual windows or skylights. This allows any room to receive natural-like lighting regardless of exterior access.
Solution Approach 2:
The system employs adjustable CCT (color temperature) and CRI (color rendering index) parameters in the LED lighting to replicate different aspects of natural sunlight. By varying these parameters, the artificial light can match the spectral properties of daylight at different times, providing versatile natural lighting benefits to all occupants.
2Illumination intensity
If conventional lighting fixtures are used, then illumination is provided, but the appearance and adjustability of natural lighting cannot be replicated
Solution Approach 1:
The patent implements adjustable CCT and CRI parameters in the LED lighting system, allowing dynamic modification of light characteristics to match natural sunlight at different times of day. This provides both adequate illumination and the adaptability of natural lighting, resolving the limitation of conventional fixed-spectrum fixtures.
3Adaptability or versatility
If LEDs are used to mimic natural light, then artificial lighting can be provided without exterior access, but the visual appearance and depth perception of traditional windows are not achieved
Solution Approach 1:
The patent introduces a diffuser panel as an intermediary between the LED light source and the viewer. This diffuser scatters the light to create a uniform glowing appearance that mimics the visual effect of natural light passing through a window, providing depth perception and aesthetic quality without requiring actual exterior access.
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
Enables the creation of a visually convincing and adjustable artificial lighting system that mimics natural light, providing the benefits of sunlight to all room occupants without the need for exterior access, enhancing productivity and ambiance.
Implementation Method 1
The light source when controlled to the 'on' state illuminates the diffuser, which diffuses the light source in such a way as to appear approximately uniform over its surface
Implementation Method 2
The light from the diffuser passes through the front panel, providing the visual impression of depth to the light source
