Luminaire Locking Element for Modular LED Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED light sources in luminaires are difficult to replace due to protection requirements against electrostatic discharge and high voltages, necessitating specialized personnel for safe handling and installation.
Innovation Solution
A lamp design featuring a centrally positioned locking element that can be moved between locking and release positions, allowing for easy detachment and secure attachment of multiple LED modules, ensuring safety and ease of replacement without the need for individual locking mechanisms for each LED.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED light sources are protected within luminaires against electrostatic discharge and high voltages, then safety and reliability are improved, but ease of replacement deteriorates as specialized personnel are required
Solution Approach 1:
The luminaire is divided into modular components: a carrier element that remains fixed in the luminaire and lamp modules that can be easily exchanged. The locking element on the carrier element secures multiple lamp modules simultaneously, allowing safe protection of high-voltage components while enabling simple replacement of individual LED modules without requiring specialized personnel.
Solution Approach 2:
A locking element acts as an intermediary mechanism between the carrier element and lamp modules. This locking element can be moved between a locking position (securing modules safely) and a release position (enabling easy removal), thus mediating between the need for safe protection and ease of replacement.
2Adaptability or versatility
If multiple LED modules are arranged one behind the other on a carrier element, then lighting performance and versatility are improved, but device complexity increases making replacement more difficult
Solution Approach 1:
The locking element on the carrier element is designed with multi-functionality to interact with all lamp modules arranged one behind the other. A single locking element can secure multiple modules simultaneously, and a single release action can detach all modules at once. This universal locking mechanism simplifies the replacement process despite having multiple modules, maintaining versatility while reducing replacement complexity.
3Reliability
If individual locking mechanisms are provided for each LED element, then security against accidental detachment is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
Multiple individual locking mechanisms are merged into a single locking element on the carrier element. This single locking element interacts with all lamp modules simultaneously, providing security against accidental detachment for all modules at once. The locking element can be moved to a locking position that secures all modules or a release position that allows easy removal of all modules, thereby combining multiple functions into one simple mechanism.
