Angled T-Bar Lighting for Lateral Wall Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing T-bar lighting systems for dropped ceilings are limited to downward lighting, failing to focus light on specific areas like walls without significant space occupation or visual obtrusiveness, and often generate heat that burdens air-conditioned spaces.
Innovation Solution
An asymmetrical and angled T-bar with a built-in lighting source that shines light laterally, using high-intensity LEDs and a diffuser to direct light at desired angles, while incorporating a heat sink to manage heat transfer and minimize visual impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional downward lighting is used in T-bars, then the lighting structure is simple and easy to manufacture, but the light cannot be focused on specific areas like walls or artwork
Solution Approach 1:
The patent applies asymmetry by positioning the lighting source off-center within the T-bar structure and angling it at a specific orientation (e.g., 45 degrees) rather than symmetrically downward. This asymmetric configuration enables the light to reach lateral surfaces like walls and artwork while maintaining integration within the standard T-bar framework, thus improving adaptability without substantially increasing complexity.
Solution Approach 2:
The invention transitions from purely vertical downward lighting to multi-directional lighting by introducing angular orientation. The lighting source is positioned and angled to emit light in multiple dimensions - both downward and laterally - allowing illumination of vertical surfaces and artwork while remaining integrated within the horizontal T-bar structure.
2Illumination intensity
If spotlights are used to focus light on specific points, then light can be directed at walls or artwork, but the spotlights occupy more space and become visually obtrusive
Solution Approach 1:
The patent merges the lighting function with the structural T-bar by integrating the lighting source directly into the T-bar assembly. This combination eliminates the need for separate spotlight fixtures, reducing space occupation and visual obtrusiveness while maintaining the capability to focus light on specific areas through angular positioning and reflective surfaces.
Solution Approach 2:
The invention uses reflective surfaces and angular positioning to create multiple light paths from a single compact source, effectively 'copying' the light distribution pattern of multiple spotlights while using only one integrated source, thereby reducing space and visual clutter.
3Ease of manufacture
If conventional T-bar lighting is used, then the structure is simple, but heat generated by the lighting burdens the air-conditioned space
Solution Approach 1:
The patent extracts the heat management function from the basic T-bar structure by incorporating dedicated heat sinks and thermal management components. These extracted heat management elements are integrated into the T-bar assembly, allowing the structure to remain relatively simple while effectively removing heat from the air-conditioned space through conductive and convective pathways.
4Adaptability or versatility
If lighting is integrated into T-bars, then the lighting is concealed and unobtrusive, but the light cannot be focused laterally on walls or artwork
Solution Approach 1:
The patent employs asymmetry in the housing design, creating an angled or directional light path through asymmetric positioning of the light source and use of reflective surfaces. This asymmetric configuration enables lateral light projection onto walls and artwork while maintaining the concealed integration within the T-bar, with the asymmetric elements being simple geometric modifications rather than complex mechanisms.

AI summary
A housing is located at least partially beneath a rest shelf of a T-bar or other support for ceiling tiles. A spine extends up from the rest shelf. The housing includes an opening with a centerline which extends at least partially laterally. A light source such as an LED within a recess of the housing shines out of the opening along the centerline in an at least partially lateral direction. A diffuser is preferably provided spanning this opening. The housing preferably includes a front wall opposite a rear wall, with the rear wall larger than the front wall and with the opening in the housing extending between lower portions of the rear wall and lower portions of the front wall. Heat transfer fins on an upper surface of the rest shelf and upper end of the spine are preferably provided to assist in heat dissipation.
