Solution Overview
Problem
Existing recessed light fixtures in ceilings are inflexible, requiring removal and replacement for distribution adjustments and pose challenges in servicing due to fixed positioning, leading to increased costs, environmental hazards, and safety risks.
Innovation Solution
A light engine comprising light emitting diodes on a printed circuit board attached to a heat sink with a customizable optic assembly, allowing for adjustable light distribution and easy servicing without accessing the ceiling, using a mounting frame with translating pins for safe maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If light fixtures are fixedly secured over the ceiling opening, then structural stability is improved, but ease of repair deteriorates
Solution Approach 1:
The light fixture is divided into separate components: a removable light engine assembly and a fixed mounting frame. The mounting frame remains secured to the ceiling for structural stability, while the light engine can be independently removed for repair or replacement without disturbing the ceiling structure.
Solution Approach 2:
The light engine is extracted as a separate, removable component from the mounting frame. This allows the light engine to be taken out for servicing while the mounting frame remains in place, eliminating the need to access the ceiling for routine maintenance.
2Stability of the object's composition
If light fixtures are fixedly secured over the ceiling opening, then structural stability is improved, but loss of time increases
Solution Approach 1:
By segmenting the fixture into a fixed mounting frame and a removable light engine, maintenance tasks can be performed quickly by simply detaching the light engine from below, eliminating time-consuming ceiling access requirements.
Solution Approach 2:
The mounting frame is pre-installed and securely fixed to the ceiling structure beforehand, creating a ready-made mounting interface that allows rapid installation and removal of light engines without requiring ceiling access during maintenance operations.
3Ease of manufacture
If light distribution is fixed, then manufacturing simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The light distribution characteristics are made dynamic and adjustable through interchangeable optic assemblies. Different optics can be installed on the same light engine to change the light distribution pattern, allowing the system to adapt to various applications without manufacturing different entire fixtures.
Solution Approach 2:
A universal light engine design with interchangeable optics allows a single base unit to serve multiple functions and applications. The same light engine can be configured with different optic assemblies to provide various light distribution patterns, making the system highly adaptable.
4Reliability
If servicing requires full access to the ceiling above the fixture, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The light engine is extracted as a removable component that can be serviced from below the ceiling. This eliminates the need to access the ceiling for routine maintenance while maintaining reliable electrical connections through a secure mounting interface.
Solution Approach 2:
The mounting frame acts as an intermediary structure that provides reliable electrical and mechanical connections between the ceiling infrastructure and the removable light engine. This intermediary interface allows easy removal of the light engine while maintaining system reliability.

AI summary
A light engine that includes light emitting diodes mounted on a printed circuit board, which in turn is attached to a heat sink. An optic assembly is positioned over the printed circuit board to direct the emitted light as desired. The light engine can be positioned. within the ceiling within the opening of a mounting frame. In some embodiments, the light engine is retained on the mounting frame such that it can be moved clear of the mounting frame opening.
