Light Module Base and Connectors for Heat Dissipation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting apparatuses face inefficiencies in both electrical connection and heat dissipation due to the need for radial forces on electrical contacts, which complicate the structure and can lead to instability.
Innovation Solution
The use of a base made of high-dissipative material, such as aluminum, with removable first connectors featuring insulating elements and rotation locking mechanisms, allows for efficient heat transfer and stable electrical connections without radial pressures, accommodating various light source configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If radial forces are applied to electrical contacts to maintain thermal contact, then heat dissipation is improved, but electrical connection stability deteriorates
Solution Approach 1:
The base is divided into functionally distinct zones: a heat dissipation zone with high thermal conductivity material for thermal contact, and an electrical connection zone with insulating material for stable electrical contacts. This segmentation allows each zone to optimize its specific function without interfering with the other.
Solution Approach 2:
Different regions of the base have different material properties tailored to their specific functions. The heat dissipation region uses materials with high thermal conductivity, while the electrical connection region uses materials with high electrical insulation properties. This local differentiation resolves the contradiction by providing appropriate material characteristics in each location.
2Temperature
If radial forces are applied to electrical contacts, then thermal contact is maintained, but device complexity increases
Solution Approach 1:
The base integrates multiple functions into a single component: it provides structural support, thermal dissipation, and electrical insulation. By combining these functions in one element rather than using separate components, the design reduces overall structural complexity while maintaining effective thermal contact.
3Temperature
If radial forces are applied to electrical contacts, then thermal contact is maintained, but manufacturing difficulty increases
Solution Approach 1:
The base is pre-designed and pre-assembled with the light source and optical components before installation. The rotational locking mechanism is pre-configured to automatically maintain proper contact pressure during installation, eliminating the need for complex post-installation adjustments or specialized assembly tools.
4Temperature
If rotational locking mechanisms are used to fix the base, then heat exchange surface contact is improved, but electrical contact stress is eliminated
Solution Approach 1:
The base is divided into functionally distinct zones: a heat dissipation zone with high thermal conductivity material for thermal contact, and an electrical connection zone with insulating material for stable electrical contacts. This segmentation allows each zone to optimize its specific function without interfering with the other.
Solution Approach 2:
Different regions of the base have different material properties tailored to their specific functions. The heat dissipation region uses materials with high thermal conductivity, while the electrical connection region uses materials with high electrical insulation properties. This local differentiation resolves the contradiction by providing appropriate material characteristics in each location.
