Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional heat sinks in lamps have a complex structure with poor integrity, making them difficult to assemble and resulting in unstable heat dissipation performance, which affects the efficiency of heat transfer as lamp power increases with the development of high-performance lighting.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional heat sink structure is used, then the heat dissipation function is provided, but the structure is complex with poor integrity making assembly difficult and stability poor
Solution Approach 1:
The patent combines the heat sink with the bracket into an integrated structure. The bracket serves dual functions as both a mounting component and a heat dissipation component, eliminating the need for separate heat sink structures. This merging resolves the contradiction by providing stable heat dissipation through the integrated design while simplifying the overall structure and improving assembly integrity.
2Ease of manufacture
If a traditional heat sink is fixed with complicated structure, then heat dissipation is achieved, but it is not easy to assemble and fins are easy to damage
Solution Approach 1:
By integrating the heat sink with the bracket, the patent creates a single unified component that is easier to manufacture and assemble. The integrated structure eliminates multiple assembly steps and reduces the risk of damaging delicate fins during assembly, while maintaining structural stability through the unified design.
Solution Approach 2:
The bracket-heat sink integration is designed as a modular component that can be separately manufactured and then installed as a complete unit. This segmentation approach allows for optimized manufacturing of the integrated structure while simplifying the assembly process compared to traditional separate components.
3Power
If lamp power increases for high-performance lighting, then lighting performance improves, but heat generation increases requiring better heat dissipation
Solution Approach 1:
The patent converts the harmful heat generated by high-power lighting into a beneficial feature by using the bracket-heat sink structure to actively dissipate the heat. The heat dissipation function is integrated into the mounting structure itself, turning the heat management challenge into an opportunity to demonstrate the effectiveness of the integrated design.

AI summary
A lamp includes a housing, a heat sink, a light source and at least a bracket. The heat sink is disposed within the housing. The light source is connected with the heat sink. The bracket is disposed within the housing, and the bracket includes a main body and a first fixing portion arranged along the outer edge of the main body. The main body of the bracket connected to a side surface of the heat sink is connected to the housing through the first fixing portion to dispose the heat sink in the housing. When the bracket is fixedly connected to the inner wall of the housing, the heat sink can be firmly installed inside the housing and it is not easy to loosen during use, so that the heat sink can continuously and stably dissipate for the lamp.
