Recessed Lighting Fixture Sliding Driver Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed lighting fixtures are difficult to service or update due to the inaccessible placement of drivers, ballasts, and transformers, which often requires significant demolition and increases project costs, deterring homeowners from performing lighting replacements or upgrades.
Innovation Solution
A recessed lighting fixture design featuring a light fixture housing with a driver assembly housing that can move horizontally and vertically, allowing easy access for servicing and replacement by sliding the light assembly housing downward through the ceiling, facilitating the connection or reconnection of lighting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the driver assembly is placed away from the light assembly to reduce heat buildup, then thermal management is improved, but accessibility for servicing and replacement deteriorates
Solution Approach 1:
The lighting fixture is divided into separate light assembly and driver assembly components that can be independently accessed and serviced. The driver assembly is positioned in a separate location within the fixture housing, allowing it to be thermally isolated from the light sources while remaining accessible through the same service opening.
Solution Approach 2:
A service opening or access panel is introduced as an intermediary element that provides access to both the light assembly and driver assembly without requiring demolition of the ceiling or wall. This access point serves as a mediator between the external service environment and the internal components.
2Ease of operation
If minimal features are provided to secure the lighting fixture to simplify installation, then installation ease is improved, but serviceability after installation deteriorates
Solution Approach 1:
The service opening serves multiple functions: it allows for initial installation access, ongoing maintenance, component replacement, and troubleshooting. This single access point is designed to handle various service scenarios without requiring additional openings or demolition work.
Solution Approach 2:
The service opening is pre-configured during manufacturing to provide future access to internal components. This preliminary structural feature ensures that servicing can be performed easily later without requiring demolition, as the access path was already established during fixture assembly.
3Strength
If the driver is placed in a location that requires ceiling or wall demolition for access, then thermal management and structural integrity are improved, but project cost and complexity increase
Solution Approach 1:
The driver assembly is extracted from the main light assembly housing and positioned in a separate compartment that is accessible through the existing service opening. This extraction allows the driver to be thermally isolated and structurally integrated without requiring additional ceiling or wall demolition for access.

AI summary
A recessed lighting fixture apparatus is disclosed. An example apparatus includes a driver box, a light box, and a fixture box each with an open side and closed sides. The open side of each of the boxes is configured to face an internal side of a ceiling. The example driver box and light box are adapted to slide together horizontally within the fixture box to enable access to either of the light box and the driver box through an opening in a ceiling. In addition, the light box is adapted to slide vertically relative to the driver box to enable a portion of the light box to be pulled through the opening in the ceiling to facilitate servicing of a light assembly.
