Trimless Recessed Light Fixture With Aperture-Covering Diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional recessed lighting fixtures require additional decorative trim elements to cover the ceiling aperture, creating an unfinished appearance and additional hardware, which is visually unappealing.
Innovation Solution
A trimless recessed light fixture design utilizing an outermost diffuser lens that provides illumination and covers the ceiling aperture, eliminating the need for additional trim elements by integrating LEDs and an optical stack to redirect light through the diffuser lens, creating a smooth, continuous illumination effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional recessed lighting fixtures use separate trim pieces to cover the ceiling aperture, then the aperture is covered and a finished appearance is achieved, but the fixture becomes more complex with additional hardware and visual clutter
Solution Approach 1:
The patent combines the trim function and illumination function into a single integrated diffuser lens assembly. The outermost diffuser lens serves dual purposes: it diffuses light to provide illumination while simultaneously covering the ceiling aperture to create a finished appearance. This merging eliminates the need for separate trim pieces, reducing device complexity while maintaining the desired aesthetic outcome.
Solution Approach 2:
The diffuser lens is designed to perform multiple functions: light diffusion, aperture coverage, and aesthetic finishing. By making the diffuser lens universal and multi-functional, the patent eliminates the need for additional specialized trim components, thereby reducing overall fixture complexity while achieving the same visual效果的.
2Shape
If traditional recessed lighting fixtures include separate trim pieces, then the aperture edges are covered, but the fixture requires additional hardware and assembly steps
Solution Approach 1:
The patent merges the trim coverage function with the illumination diffuser into a single integrated component. The outermost diffuser lens is designed to extend outward to cover the ceiling aperture edges while simultaneously providing light diffusion. This integration eliminates the need for separate trim pieces and reduces assembly complexity, making manufacturing and installation easier.
3Shape
If traditional recessed lighting fixtures use multiple components including trim and baffles, then the aperture is covered, but the fixture lacks a smooth continuous illumination appearance
Solution Approach 1:
The patent combines the trim coverage function with the illumination diffuser into a single integrated component. The outermost diffuser lens is designed to extend outward to cover the ceiling aperture edges while simultaneously providing light diffusion. This integration eliminates the need for separate trim pieces and reduces assembly complexity, making manufacturing and installation easier.
Solution Approach 2:
The diffuser lens is designed with specific local properties: it is translucent to diffuse light evenly while extending outward to cover the aperture edges. The optical stack and light guide are positioned to ensure uniform light distribution across the entire diffuser surface, creating a smooth continuous illumination appearance without visible hardware or abrupt transitions.
4Shape
If traditional recessed lighting fixtures include visible hardware and trim, then the aperture is covered, but the overall fixture appearance is cluttered and less aesthetically pleasing
Solution Approach 1:
The patent combines the trim function and illumination function into a single integrated diffuser lens assembly. The outermost diffuser lens serves dual purposes: it diffuses light to provide illumination while simultaneously covering the ceiling aperture to create a finished appearance. This merging eliminates the need for separate trim pieces, reducing device complexity while maintaining the desired aesthetic outcome.
Solution Approach 2:
The diffuser lens is designed to be translucent, allowing it to evenly distribute and soften the light output while maintaining a uniform appearance. The optical stack and light guide are positioned to ensure uniform light distribution across the entire diffuser surface, creating a smooth continuous illumination effect that enhances visual appeal and eliminates visible hardware.
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 solution achieves a visually seamless, illuminated appearance without visible hardware, providing uniform light coverage over the ceiling aperture while maintaining a finished look.
Implementation Method 1
an optical stack which collects light output from the LEDs and both illuminates and redirects the light through the outermost diffuser lens
Implementation Method 2
This outermost diffuser lens provides the appearance of smooth continuous illumination output along its entire surface
Data Source
AI summary
The present disclosure is directed towards an LED based trimless recessed light fixture wherein the outermost diffuser lens of the recessed fixture provides illumination and extends outward covering the entire ceiling aperture. No additional decorative trim elements or baffles are required and the diffuser lens both illuminates and covers the ceiling aperture to provide a smooth illuminated unitary appearance. This outermost diffuser lens is illuminated from above by a illumination system which includes a ring support on which the LEDs may be mounted, along with an optical stack which collects light output from the LEDs and both illuminates and redirects the light through the outermost diffuser lens. This outermost diffuser lens provides appearance of smooth continuous illumination output along its entire surface and while also covering aperture edges formed in the ceiling for the recessed fixture.
