Pre-assembled Light Engine with Detachable Lens and Optical Tray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional luminaires require multiple installation steps due to separate attachment of optical trays and lenses, complicating the installation process and maintenance.
Innovation Solution
A luminaire design featuring a pre-assembled light engine with a detachably secured optical tray and lens, which can be easily attached to a housing as a single unit, reducing installation steps and facilitating servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the optical tray and lens are attached separately to the housing, then the luminaire can be assembled from individual components, but the number of installation steps increases and installation complexity increases
Solution Approach 1:
The patent combines the optical tray and lens into a single integrated light engine assembly that attaches to the housing as one unit. This merging eliminates the separate attachment steps for the optical tray and lens, reducing installation complexity while maintaining the ability to assemble from components.
Solution Approach 2:
The patent segments the luminaire into two main assemblies: the housing and the integrated light engine (combining optical tray and lens). This segmentation allows the light engine to be pre-assembled and tested separately, then installed as a single module, reducing on-site installation steps.
2Ease of repair
If the optical tray and lens are attached separately, then component replacement is possible, but maintenance time and installation time increase
Solution Approach 1:
The patent implements a detachable connection between the light engine and housing, allowing the light engine to be quickly removed and replaced as a single unit. This dynamic design enables rapid maintenance without requiring separate disassembly of the optical tray and lens, reducing maintenance time.
Solution Approach 2:
The optical tray and lens are pre-assembled into an integrated light engine before delivery to the installation site. This preliminary assembly ensures proper alignment and reduces on-site installation time, while the detachable design allows the pre-assembled unit to be quickly replaced during maintenance.
3Adaptability or versatility
If multiple components are attached separately, then flexibility in assembly is maintained, but the number of parts increases and assembly complexity increases
Solution Approach 1:
The patent merges the optical tray and lens into a single integrated light engine assembly, reducing the total number of parts from three separate components (housing, optical tray, lens) to two main assemblies (housing, light engine). This maintains assembly flexibility through detachable connections while simplifying the overall structure.

AI summary
A luminaire includes a housing and a light engine. The light engine is detachably secured to the housing and includes a lens and an optical tray. The lens has a top surface, a bottom surface, and a peripheral edge. The top surface of the lens define a lens cavity. The optical tray is supported by the lens within the lens cavity.
