Luminaire Light Source Module Mechanical Clamping Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible light source boards in luminaires suffer from poor structural stability due to adhesive fixation, which is prone to failure under environmental factors like temperature and humidity.
Innovation Solution
A light source module comprising a light source board, a heat dissipating component, a first sleeving component, and a second sleeving component, where the second sleeving component presses the light source board onto the mounting base portion through the first sleeving component, providing a secure clamp that avoids pressure on the illuminators and ensures stable light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive fixation is used to attach the flexible light source board, then the structure is simple and easy to manufacture, but the structural stability deteriorates due to adhesive failure under environmental factors
Solution Approach 1:
The patent replaces the chemical adhesive bonding system with a mechanical clamping system using a clamp component. The clamp has a clamping cavity that mechanically secures the flexible light source board between the clamp and the heat dissipating component, eliminating reliance on adhesive bonds that fail under environmental factors like temperature and humidity.
2Reliability
If the light source board is firmly fixed to ensure stability, then the structural stability improves, but the illuminators may be damaged due to excessive pressure
Solution Approach 1:
The clamp component is designed with a clamping cavity that provides localized, distributed pressure across the flexible light source board. This allows firm fixation for stability while avoiding concentration of force on specific points where illuminators are located, thus preventing damage to the illuminators while maintaining overall structural stability.
