Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamp structures suffer from poor heat dissipation, high cost, and inconvenient assembly due to the placement of the driver within an aluminum alloy heat dissipation body, which leads to malfunctions and difficulty in disassembly and reassembly.
Innovation Solution
A lampshade fixing structure featuring an aluminum substrate with LED lamp beads, a lampshade peripherally arranged, positioning bosses, L-shaped notches, and a limiting seat for secure connection, along with a separate driving power supply box and improved heat dissipation design, allowing for stable assembly and easy driver replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the driver is located in the aluminum alloy heat dissipation body, then the heat dissipation structure is integrated, but the heat dissipation effect is poor and the driver temperature is high causing malfunctions
Solution Approach 1:
The patent divides the lamp structure into separate functional modules: the driver is housed in an independent plastic shell (forming a driver assembly), while the aluminum substrate serves solely for heat dissipation and LED mounting. This segmentation allows the driver to be isolated from excessive heat while maintaining structural organization.
Solution Approach 2:
The driver is extracted from the heat dissipation body and placed in a separate location within the lampshade assembly. The aluminum substrate is dedicated only to heat dissipation, while the driver assembly is positioned separately and connected via wiring, thereby removing the driver from the high-temperature environment.
2Temperature
If the aluminum alloy heat dissipation body is used, then heat dissipation is provided, but the cost is high and the heat dissipation effect is not necessarily good
Solution Approach 1:
The patent replaces expensive aluminum alloy heat dissipation bodies with a more economical plastic shell for the driver housing. The heat dissipation function is achieved through a simpler aluminum substrate specifically designed for thermal management of LEDs, while the driver housing uses cost-effective plastic materials.
3Strength
If the driver is installed by welding, then the connection is strong, but the disassembly and assembly is inconvenient
Solution Approach 1:
The driver assembly is segmented into a removable unit housed in its own shell, connected to the main lamp body through electrical connections rather than permanent welding. This allows the driver to be easily detached and replaced without damaging the lamp structure.
Solution Approach 2:
The connection method transitions from static welded joints to dynamic, reversible electrical connections. The driver assembly can be inserted and removed from the lampshade, enabling easy maintenance and replacement while maintaining reliable electrical contact during operation.
4Stability of the object's composition
If the lampshade is connected with the aluminum alloy heat dissipation body by threaded connection, then the assembly is secure, but the structure is complex and disassembly is difficult
Solution Approach 1:
The lampshade and driver assembly are merged into a more integrated configuration where the driver housing forms part of the lampshade structure. The positioning notches and limiting seats create an integrated fixing mechanism that simplifies the overall assembly while maintaining security.
