Busbar Profile Opening for Shadow-Free Indirect Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar systems for lighting modules create shadowing effects when attempting to deflect light upwards for indirect lighting, preventing uniform indirect illumination.
Innovation Solution
A busbar system with a support profile that has an opening on one side to accommodate a lighting element with a light source and optical element, allowing light to be emitted upwards without shadowing, and featuring a power supply line within the profile for secure power distribution, enabling independent control of indirect lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a support profile with open cross-section is used to support lighting modules for direct downward lighting, then direct lighting is achieved, but the support profile causes shadowing that prevents uniform indirect lighting when light is redirected upwards
Solution Approach 1:
The support profile is segmented by introducing openings that divide the solid structure into sections, allowing light to pass through the profile rather than being blocked by it. This segmentation eliminates the shadowing effect while maintaining the structural integrity needed for supporting lighting modules.
Solution Approach 2:
The opening in the support profile acts as an intermediary element that allows upward-directed light to pass through the profile without being blocked. This intermediary structure enables uniform indirect lighting by mediating between the light source and the ceiling surface.
2Adaptability or versatility
If additional structures are added on top of the support profile to enable upward light emission, then indirect lighting is possible, but the device complexity increases
Solution Approach 1:
The support profile is designed to perform multiple functions: it provides mechanical support for lighting modules, enables direct downward lighting through its open cross-section, and simultaneously enables indirect upward lighting through integrated openings. This multi-functionality eliminates the need for separate additional structures.
Solution Approach 2:
The opening for upward light emission is merged directly into the support profile structure itself, rather than being a separate component. This integration combines the support function and the light emission function into a single unified structure, reducing overall device complexity.
3Ease of manufacture
If the lighting element is integrated into the support profile through an opening, then space is saved and cleaning is facilitated, but the light source must be positioned precisely to avoid gaps that could allow dirt ingress
Solution Approach 1:
The lighting element is designed with specific local qualities: its outer surface is shaped to match the opening geometry, creating a flush fit that prevents gaps. This local adaptation ensures that the integrated design maintains both ease of manufacture and protection against dirt ingress.

AI summary
The conductor rail system has a support profile (2) for supporting a lamp module, where the support profile has a transverse section that is opened in a direction (u). A disposal of light is provided in the direction, where the light is generated by the lamp module. A lamp element (4) is provided with a light source for a light disposal in another direction (o).
