Indirect Lighting Structure with Reflective Wall and Profile Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous structures, such as false ceilings and slabs, often suffer from non-homogeneous light diffusion and visibility of defects due to the distance and distribution of light sources, leading to aesthetic issues.
Innovation Solution
A luminous structure with interconnected walls and a profile that houses light means, where one wall diffuses light and the other reflects it, using oblique slots to direct light for indirect lighting, ensuring homogeneous diffusion and concealing defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light means are fixed directly to the bottom of the frame with a tablecloth diffuser, then the structure is simple to manufacture, but homogeneous light diffusion cannot be ensured and defects become visible
Solution Approach 1:
The frame is segmented into multiple profiles with slots, and the light means are distributed across these profiles rather than concentrated at the bottom. This segmentation allows each profile to contribute to homogeneous light diffusion across the entire visible surface, eliminating the non-uniform distribution caused by bottom-mounted lights.
Solution Approach 2:
A reflective wall is introduced as an intermediary element between the light means and the diffusing tablecloth. The reflective wall redirects light from the slots to illuminate the tablecloth from multiple angles, ensuring homogeneous diffusion while keeping the light sources hidden within the profile slots.
2Manufacturing precision
If the tablecloth is placed close to the light sources, then the structure is compact, but defects in the tablecloth become visible and light diffusion is non-homogeneous
Solution Approach 1:
Different regions of the tablecloth receive light from different profiles and angles via the reflective wall. This creates local variations in illumination that mask defects in specific areas, as no single defect is uniformly illuminated from all angles as would occur with direct bottom lighting.
Solution Approach 2:
The lighting system transitions from a single-plane bottom illumination to a multi-dimensional approach where light travels from horizontal slots, reflects off the vertical reflective wall, and then illuminates the tablecloth from multiple angles. This dimensional change in light paths ensures homogeneous diffusion and hides defects.
3Illumination intensity
If light means are distributed across the bottom surface, then light coverage is improved, but the structure complexity increases and installation becomes more difficult
Solution Approach 1:
The profiles serve multiple functions: they provide structural support for the frame, contain the light means within their slots, and position the light sources at optimal locations for reflection. This multi-functionality reduces the need for additional components and simplifies installation while achieving comprehensive light coverage.

AI summary
The invention relates to a lighting structure (1) including two walls (2, 3) interconnected by at least one profile member (4), and lighting means (7). The profile member (4) defines, with said walls (2, 3), a closed inner space (5). One of the walls (3) is capable of spreading the light emitted by the lighting means. The structure (1) is characterized in that the other wall (2) has at least one surface (20) capable of reflecting the light emitted by the lighting means, and in that the profile member (4) comprises at least one slot (6) in which the lighting means (7) are housed. Said slot (6) has an opening (60) in the inner space (5) and is arranged such that the light, leaving the profile member (4), is directed towards the surface (20) capable of reflecting the light.
