Lighting Apparatus Wire Routing via Segmented Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conductive wires connecting functional modules in lighting apparatuses often pass through light source cavities, reducing light efficiency due to interference with optical paths.
Innovation Solution
The lighting apparatus design separates the accommodating cavity into a light source cavity and a via cavity, with the conductive wire passing through the via cavity and a via hole, avoiding the light source cavity to prevent interference, and includes a functional module mounted in an installation cavity for detection, indicating, or warning functions.

1Reliability
If conductive wires are routed through the light source cavity to connect functional modules, then electrical connectivity is achieved, but light transmission is obstructed and light efficiency is reduced
Solution Approach 1:
The accommodating cavity is divided into two separate cavities: a light source cavity for housing the light source module and a via cavity for routing conductive wires. This segmentation allows electrical connectivity and light transmission to occur in separate spatial zones, eliminating mutual interference while maintaining both functions independently.
Solution Approach 2:
The conductive wires are extracted from the light source cavity and relocated to the via cavity. By removing the wires from the optical path area, the light source cavity remains clear for optimal light transmission, while the via cavity provides a dedicated channel for electrical connections to the functional module.
2Illumination intensity
If the accommodating cavity is separated into light source cavity and via cavity, then light efficiency is improved, but device complexity increases
Solution Approach 1:
The inner housing simultaneously performs multiple functions: it forms the wall between the light source cavity and via cavity, provides mounting surfaces for both the light source module and functional module, and creates the installation cavity. By merging these functions into a single component, the overall device complexity is reduced despite the cavity separation.
Solution Approach 2:
The inner housing is designed as a multi-functional component that provides structural separation, mounting support, and cavity formation. This universal component approach consolidates what could have been multiple separate parts, maintaining manufacturing simplicity while achieving the required cavity segmentation for optimal light efficiency.
