Solution Overview
Problem
Conventional light emitting assemblies face inefficiencies in heat dissipation, leading to uneven light emission distribution and increased temperature at the top, which can reduce light emission efficiency, and often require bulky heat sinks that increase production costs.
Innovation Solution
A light emitting assembly with air passages between plates to facilitate heat dissipation, where the plates are angled to allow air flow and are made of thermally conductive materials, enhancing natural convection and maintaining uniform temperature across the assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat sinks or heat pipes are used for heat dissipation enhancement, then heat dissipation efficiency is improved, but the assembly becomes bulky and heavy and production costs increase
Solution Approach 1:
The patent combines the light emitting source mounting plate with the heat dissipation function by integrating air passage structures directly into the plate design. The plate serves dual purposes: supporting light emitting sources and facilitating heat dissipation through built-in air flow channels, thereby eliminating the need for separate heat sinks or heat pipes.
Solution Approach 2:
The mounting plate is designed to perform multiple functions simultaneously: structural support for light emitting sources, heat conduction from the sources, and heat dissipation through integrated air passages. This multi-functional design replaces what would traditionally require separate components.
2Temperature
If air flows from bottom to top through the plate, then heat dissipation occurs, but the air temperature increases along the flow path reducing dissipation efficiency at the top
Solution Approach 1:
The patent segments the air flow path into multiple independent passages arranged in parallel between the mounting plate and the cover plate. This segmentation allows different air streams to flow simultaneously at different heights, preventing the progressive heating problem that occurs in single vertical flow paths and maintaining more uniform heat dissipation across the entire plate surface.
Solution Approach 2:
The patent transitions from a single vertical heat dissipation path to a three-dimensional network of multiple parallel air passages. By distributing heat dissipation across multiple spatial dimensions and creating a multi-layered airflow structure, the system achieves more uniform temperature distribution and prevents the progressive heating effect.
3Temperature
If the plate temperature is high at the top, then heat dissipation is reduced, but this causes uneven light emission distribution
Solution Approach 1:
By dividing the heat dissipation system into multiple parallel air passages, the patent creates multiple independent cooling zones that correspond to different regions of the mounting plate. This segmentation ensures more uniform temperature distribution across the plate surface, which directly translates to uniform light emission from all light emitting sources.
