Lighting Apparatus With Integrated Limit Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting apparatuses lack ease of installation and detachment, particularly in commercial environments, and require complex wiring solutions, which complicates flexibility and safety in assembly and maintenance.
Innovation Solution
A lighting apparatus design featuring a limit switch, wiring box, and base holder with a terminal connector, where the light source module triggers the limit switch to enable power supply only when correctly installed, using elastic springs for assembly simplification and multiple fixing columns for secure attachment, and a reflector cup for adjustable illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wiring solutions are used for lighting apparatus installation, then electrical connection is achieved, but installation complexity and time increase
Solution Approach 1:
The lighting apparatus is divided into modular components (light source module, base holder, wiring box) that can be independently installed and connected. The limit switch is integrated into the base holder as a separate module, allowing for simplified wiring where the light source module simply needs to be connected to the base holder rather than requiring complex hardwired connections.
Solution Approach 2:
The limit switch automatically detects when the light source module is properly installed and triggers the power supply connection without requiring manual intervention. The system self-activates when the module is inserted, eliminating the need for manual switch operation or complex wiring configurations.
2Adaptability or versatility
If fixed lighting apparatus installation is used, then stable electrical connection is achieved, but flexibility for module replacement decreases
Solution Approach 1:
The electrical connection system transitions from a static fixed wiring arrangement to a dynamic plug-and-play system. The limit switch lever moves between disconnected and connected positions based on module installation status, allowing the system to adapt between different operational states while maintaining reliable connections when installed.
Solution Approach 2:
The base holder with integrated limit switch serves multiple functions: it provides mechanical support for the light source module, establishes electrical connection through the terminal connector, and controls power supply activation through the limit switch. This multi-functional design allows for easy module replacement while maintaining reliable connections.
3Object-affected harmful factors
If manual power switch is used, then power control is achieved, but safety risk of electrical shock increases
Solution Approach 1:
The limit switch automatically controls power supply activation based on the installation status of the light source module. When the module is properly installed and triggers the lever, power is automatically supplied without requiring manual intervention, eliminating the need for separate power switches and reducing electrical shock risks from manual handling of live components.
Solution Approach 2:
The limit switch is positioned and configured to prevent power supply activation before the light source module is properly installed. The lever remains in a position that blocks electrical connection until the module is correctly positioned, preventing accidental activation and electrical shock hazards during installation or maintenance.
4Device complexity
If complex wiring box design is used, then complete electrical connection is achieved, but device complexity increases
Solution Approach 1:
The limit switch is integrated directly into the base holder structure, merging the switching mechanism with the mounting structure. The terminal connector is also integrated into the base holder, combining multiple electrical connection functions into a single unified component rather than requiring separate wiring boxes and switches.
Solution Approach 2:
The base holder serves as a multi-functional component that provides mechanical mounting, electrical connection through the terminal connector, and power control through the integrated limit switch. This consolidation eliminates the need for separate complex wiring structures while maintaining complete and reliable electrical connections.

AI summary
A lighting apparatus includes a limit switch, a wiring box, a base holder and a light source module. The wiring box is for disposing the limit switch and for receiving a power wire connected to an external power. The base holder having a terminal connector electrically connected to the wiring box. The base holder has an opening for inserting a lever of the limit switch. The light source module is installed into the base holder. The light source module triggers the lever of the limit switch to turn on power supply to the light source module via the power wire and the terminal connector.
