Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED downlights have complex structures due to separate heat-dissipating designs and drive boxes, making them difficult to produce efficiently.
Innovation Solution
An LED heat-dissipating downlight design featuring an enclosure body with a heat-dissipation material accommodating both the light source and driving boards, where the light source board is thermally contacted to the enclosure body for heat dissipation, eliminating the need for a separate heat sink and drive box, and incorporating a ring plate made of transparent or translucent material for light distribution and remote control functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate heat-dissipating design and drive box are used, then heat dissipation function is achieved, but device structure becomes complicated
Solution Approach 1:
The patent combines the heat-dissipating function and drive box accommodation into the enclosure body itself. The enclosure body is made of heat dissipation material and internally contains both the driving components and provides thermal pathways to transfer heat from the LED light sources, eliminating the need for separate heat sinks and drive boxes while maintaining effective heat dissipation.
2Temperature
If separate heat-dissipating design and drive box are used, then heat dissipation function is achieved, but production efficiency decreases
Solution Approach 1:
The patent integrates multiple functions into a single enclosure body structure that serves as both the housing and the heat dissipation system. By making the enclosure body itself the heat dissipation component and incorporating the drive box within it, the number of assembly steps is reduced and automated production becomes more feasible, thereby improving production efficiency while maintaining effective heat dissipation.
