LED Lamp Heat Sink Globe Flow Path Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting lamps face inefficiencies in heat dissipation due to the lack of a heat transfer flow path between the heat sink and the globe, which restricts air flow and hampers effective heat transfer.
Innovation Solution
A lighting lamp design featuring a heat sink with a first heat transfer flow path on its outer peripheral surface and a globe with a corresponding second heat transfer flow path, where the globe's protrusions and concave sections match the heat sink's fins and concave areas, creating a continuous path for heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional heat sink configuration without flow paths is used, then the structure is simple, but heat dissipation efficiency is poor due to restricted air flow
Solution Approach 1:
The globe is segmented with multiple protrusions that create distinct flow paths, dividing the air flow into multiple channels to enhance heat transfer efficiency while maintaining manufacturing feasibility through modular design
Solution Approach 2:
The globe incorporates a porous structure with flow paths that allow air permeation, enabling efficient heat dissipation while maintaining structural integrity and simplicity in manufacturing
2Ease of manufacture
If the globe is made smooth without protrusions, then manufacturing is easier, but heat transfer area is reduced and heat dissipation is less effective
Solution Approach 1:
The globe uses curved protrusions and concave portions instead of sharp edges, maintaining manufacturability while increasing surface area for heat transfer and improving air flow dynamics
3Device complexity
If no flow path is formed on the globe, then the structure is simpler, but air flow from LED heat emission does not reach the inner area of the heat sink, reducing heat transfer efficiency
Solution Approach 1:
The protrusions on the globe act as intermediaries that guide and channel air flow from the external environment into the inner area of the heat sink, ensuring efficient heat transfer while maintaining structural simplicity
