Modular Ceramic LED Light Source Module for Independent Cooling and Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lighting devices have a one-piece LED light source circuit structure, making them costly and inconvenient to maintain, as replacing a single damaged light source chip requires replacing the entire circuit, and the cooling efficiency is low due to the packaging of LED chips on circuit boards.
Innovation Solution
A modular light source design featuring a support member, a light source mounting member, and a lens member, where the light source mounting member is made of ceramic with a bearing surface for the LED component, and a sealant is used to create a sealed space, allowing for independent replacement of modules and improved cooling through protruding structures and clamping connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If LED light source circuit modules have a one-piece structure, then the structure is simple, but when one light source chip is damaged the whole LED light source circuit needs to be replaced resulting in high cost and inconvenient maintenance
Solution Approach 1:
The patent divides the LED light source circuit into multiple independent circuit boards, each carrying one or more light source chips. These circuit boards are independently replaceable modules connected to the housing. When a light source chip is damaged, only the specific circuit board module needs to be replaced rather than the entire circuit, thereby reducing maintenance cost and improving repair convenience while maintaining structural simplicity through modular design.
2Device complexity
If LED chip is packaged on a circuit board and then the circuit board is brought into contact with a cooling structure, then the structure is simple, but the cooling efficiency is low affecting service life and luminous efficiency
Solution Approach 1:
The patent segments the cooling function by providing each circuit board module with an independent cooling structure. The cooling structure includes a cooling cavity formed in the housing and a heat dissipation component in contact with the circuit board. This modular cooling approach allows each LED module to be cooled independently, significantly improving cooling efficiency and thereby enhancing service life and luminous efficiency without overly complicating the overall structure.
