Removable Mounting Plate Junction Box for Driver Heat Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED lighting systems require drivers to convert high-voltage AC power to low-voltage DC power, leading to inefficiencies and fire risks due to heat generation and potential sparks, and existing junction boxes can be difficult to use.
Innovation Solution
A junction box design featuring a removable mounting plate with parallel mounting slots and a divider, allowing pre-installation of drivers outside the enclosure, and a compartmentalized structure for high-voltage connections, along with a lid for access and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers are installed inside the junction box enclosure, then the electrical connections are protected, but the installation and configuration process becomes difficult and time-consuming
Solution Approach 1:
The junction box is segmented into a removable mounting plate and a base enclosure. The mounting plate can be detached from the base, allowing drivers to be pre-installed on the plate outside the enclosure, then the plate is reattached to complete the installation. This segmentation resolves the contradiction by enabling easy installation while maintaining protected electrical connections.
2Reliability
If drivers are installed inside the junction box, then the electrical connections are protected, but the time required for installation increases
Solution Approach 1:
The mounting plate is designed to allow drivers to be pre-installed and configured outside the junction box enclosure before the plate is attached to the base. This preliminary action reduces installation time while ensuring the electrical connections remain protected within the enclosure.
3Reliability
If the junction box enclosure is sealed to protect connections, then safety is improved, but heat dissipation becomes problematic
Solution Approach 1:
The mounting plate incorporates heat dissipation features such as fins or vents that provide localized thermal management. The enclosure remains sealed for safety, but the mounting plate creates controlled pathways for heat to escape, resolving the contradiction between connection protection and heat dissipation.

AI summary
A junction box has a base enclosure, a mounting plate, and a lid. The base enclosure has a back and a sidewall or plurality of sidewalls arising from respective edges of the back, thereby defining an opening. The mounting plate is adapted to be removably mounted within, and removed from, the base enclosure. The mounting plate includes at least one set of mutually parallel mounting slots extending across substantially the entirety of the mounting plate along a first direction, and a divider extending outwardly from the mounting plate. The divider is positioned to one side of the at least one set of mounting slots. The lid is adapted to be installed over the base enclosure to close the opening therein. A method of using the junction box is also disclosed.
