Bendable Reflective Canopy Luminaire Kit Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side-lit luminaires are complex and costly, requiring pre-assembly before transportation, which complicates storage and transportation and results in high packaging costs due to their multi-component design.
Innovation Solution
A kit for assembling a luminaire with a bendable reflective canopy and frame sections that allow for easy assembly by the end user, providing an indirect lighting effect without the solid state lighting elements blocking the light path, enabling efficient storage and transportation as a kit rather than a pre-assembled luminaire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional side-lit luminaires are designed with multiple components to achieve indirect lighting, then the lighting effect is improved, but the device complexity and transportation cost increase
Solution Approach 1:
The patent merges the reflective canopy and frame into a single integrated component structure. The frame sections form the perimeter of the light exit window and the reflective canopy is positioned within this frame, creating a unified assembly that provides both structural support and indirect lighting function through a single component rather than multiple separate parts.
2Reliability
If conventional side-lit luminaires are pre-assembled before transportation, then the lighting performance is ensured, but the packaging cost and storage space requirements increase
Solution Approach 1:
The luminaire is segmented into modular frame sections that can be easily assembled by end users. The frame comprises multiple sections that define the perimeter of the light exit window, allowing the product to be transported in a compact disassembled state and then quickly assembled on-site, reducing packaging volume while maintaining assembly reliability.
3Illumination intensity
If solid state lighting elements are arranged in a dense pattern to avoid darker areas, then the illumination uniformity is improved, but the luminous flux exceeds the required amount and costs increase
Solution Approach 1:
A reflective canopy is introduced as an intermediary element between the solid state lighting elements and the light exit window. The canopy reflects light from the LED array, redirecting it towards the light exit window and improving illumination uniformity across the exit area. This allows the use of fewer LED elements while achieving the desired uniformity, as the reflective canopy distributes the light more evenly across the light exit window.

Function Achieved in This Case
The solution simplifies the luminaire design, allowing for efficient packaging and transportation, reducing costs and environmental impact while maintaining luminous efficiency and providing both direct and indirect lighting effects.
Implementation Method 1
a bendable reflective canopy extending between a pair of opposing edge portions... at least a part of its luminous output is redirected by the bendable reflective canopy towards the light exit window

AI summary
Provided is a kit for assembling a luminaire comprising a bendable reflective canopy and a plurality of frame sections which define a frame and a light exit window of the luminaire. The frame sections include a pair of opposing side sections with an engagement member and side sections. The reflective canopy comprises a pair of opposing edge portions, each edge portion engaging with one of the engagement members when assembling the luminaire. The opposing side sections are spaced by the further side sections such that the reflective canopy is bent when the edge portions are engaged with the engagement members so as to cause the reflective canopy to arch over the light exit window. Solid state lighting elements are mounted on one of the side sections such that at least a part of the light emitted is redirected by the arched reflective canopy towards the light exit window.
