Solution Overview
Problem
Existing COB LED lighting systems require effective cooling solutions beyond heat sinks and fans, as they generate significant heat, and existing liquid cooling systems are complex or require additional components like heat sinks.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If COB LED modules are used for high-power illumination, then lighting efficiency and versatility are improved, but heat generation increases requiring complex cooling systems
Solution Approach 1:
The invention extracts the heat dissipation function from the traditional heat sink structure and relocates it to a separate water-cooled plate system. The cooling plate with internal water channels is detached from the LED module housing, allowing heat to be removed through liquid circulation rather than passive air cooling, thereby solving the heat generation problem while maintaining high lighting power
Solution Approach 2:
Water is introduced as an intermediary cooling medium between the heat source (LED modules) and the external environment. The water circulates through channels in the cooling plate, absorbing heat from the LED modules and transporting it to the radiator, where it is dissipated to the surroundings, effectively mediating the heat transfer process
2Temperature
If traditional heat sink cooling is used, then cooling function is provided, but device complexity and space requirements increase
Solution Approach 1:
The invention merges multiple functions into the cooling plate: it serves as both a thermal management component (with internal water channels for heat dissipation) and a structural mounting platform (with threaded openings for securing LED modules). This integration reduces the number of separate components needed and simplifies the overall cooling system architecture
Solution Approach 2:
The cooling plate is designed with multi-functionality: it provides thermal cooling through water circulation, structural support for LED modules through threaded mounting openings, and potential electrical connection pathways. This universal design reduces device complexity by eliminating the need for separate heat sinks, mounting brackets, and electrical connection components
3Temperature
If COB LED modules are permanently screwed to housing with heat sink, then stable cooling is achieved, but ease of repair and replacement deteriorates
Solution Approach 1:
The invention segments the cooling system into modular components: the cooling plate with water channels is separated from the LED modules, and the LED modules are mounted on the cooling plate using removable threaded fasteners rather than permanent bonding. This segmentation allows individual LED modules to be easily removed and replaced while maintaining stable thermal contact with the cooling plate
