LED Explosion-Proof Lamp Coupling Structure for Hazardous Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional explosion-proof lamps have limited projection ranges, leading to blind spots in hazardous environments, necessitating multiple lamps and costly connection sets for serial connections, which are also unappealing in appearance.
Innovation Solution
A LED explosion-proof lamp coupling structure featuring holding sets with protruding connection portions, connection units with sealing rings and anchor members, and adjustable fastening systems that allow for secure and angled connections of multiple lamps, hiding fastening elements for an improved aesthetic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple explosion-proof lamps are connected in series to eliminate blind spots, then the illumination coverage is improved, but the number of connection sets required increases, leading to higher cost and more complex structure
Solution Approach 1:
The patent integrates the connection function directly into the lamp body by designing a connection dock that is built-in rather than separate. The connection dock includes coupling structures (male and female coupling portions) that are integrated into the lamp housing, eliminating the need for separate connection sets. This merging of the connection function into the lamp body reduces the number of components and simplifies the overall structure while maintaining the ability to connect multiple lamps in series for expanded illumination coverage.
2Reliability
If conventional connection sets are used to connect explosion-proof lamps, then the connection reliability is improved, but the appearance becomes unappealing and consumer desirability decreases
Solution Approach 1:
The patent extracts the connection function from separate external connection sets and embeds it directly into the lamp body through the connection dock design. The male and female coupling portions are integrated into the lamp housing, so the connection mechanism is no longer an external accessory but an inherent part of the lamp structure. This extraction and integration of the connection function eliminates the unsightly appearance of separate connection sets while maintaining connection reliability through the built-in coupling structures.
3Area of stationary object
If more connection sets are required to connect additional lamps, then the illumination coverage is improved, but the installation complexity and time increase
Solution Approach 1:
The patent segments the connection function into modular male and female coupling portions that are integrated into each lamp body. Each lamp is self-contained with its own connection dock, allowing for modular assembly. This segmentation enables simple plug-and-play connection between lamps without requiring complex assembly procedures or multiple separate connection sets, thereby reducing installation time and complexity while still allowing multiple lamps to be connected for expanded coverage.

AI summary
A LED explosion-proof lamp coupling structure to couple at least two LED explosion-proof lamps includes at least two holding sets, at least two LED lighting elements, and at least one connection unit. Each holding set includes a body, a protruding connection portion located on an upper end of the body, a chamber located in the body, and at least one first coupling portion located at one end of the body and communicating with the chamber. Each first coupling portion includes a hole communicating with the chamber and a positioning seat located on chamber and abutting the hole. Each LED lighting element is connected to the protruding connection portion. The connection unit includes a connection tube connected to each first coupling portion and at least one first fastening set to fasten the connection tube to the positioning seat. Thus the holding sets can be coupled with each other.
