Solution Overview
Problem
Existing recessed LED lighting luminaires face issues with heat dissipation and non-replaceable components, leading to reduced lifespan and the need for entire fixture replacement when individual components fail.
Innovation Solution
The design incorporates detachable and replaceable components, including a heat dissipation apparatus with transverse fins for efficient cooling, a removable driver, socket, and LED chip, along with a detachable electrical connector and lens, allowing for maintenance and extension of the luminaire's life without replacing the entire unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If all components are integrated into the luminaire, then the structure is simplified and manufacturing is easier, but when one component fails the entire luminaire must be replaced increasing maintenance costs
Solution Approach 1:
The luminaire is divided into separable modules including a replaceable socket assembly, heat dissipation apparatus with fins, and LED chip assembly. Each component can be independently removed and replaced without affecting other parts, allowing selective maintenance while maintaining manufacturing simplicity.
2Stability of the object's composition
If LED chips are permanently affixed to the heat dissipation apparatus, then the structure is more stable, but the entire apparatus must be replaced if LED chips malfunction
Solution Approach 1:
The LED chip assembly is designed to be extractable from the heat dissipation apparatus through the removable socket assembly. This allows the LED chips to be separated from the thermal management component for independent replacement, while maintaining stable operation during use through secure electrical and thermal connections.
3Ease of manufacture
If a single-piece heat dissipation apparatus is used, then manufacturing is simpler, but heat dissipation efficiency is reduced and component lifespan is shortened
Solution Approach 1:
The heat dissipation apparatus incorporates multiple fin structures segmented into different regions (circumferential fins, transverse fins, and radial fins) that work together to maximize surface area and heat dissipation efficiency. The segmented design allows optimized thermal pathways while maintaining manufacturability through modular assembly.
4Strength
If the luminaire is designed with fixed components, then the structure is more robust, but maintenance requires replacement of the entire fixture increasing costs and waste
Solution Approach 1:
The luminaire incorporates dynamic maintainability through removable and replaceable components including the socket assembly, heat dissipation apparatus, and LED chip assembly. These components can be dynamically added, removed, or replaced without compromising the structural integrity of the overall luminaire housing and mounting structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances heat dissipation, reduces maintenance costs, and extends the lifespan of the luminaire by allowing individual component replacement, making it more versatile and cost-effective.
Implementation Method 1
a multiplicity of transverse fins are positioned on a top side of the plate, and are surrounded by either the longer fins or the shorter fins. Therefore, the longer and shorter longitudinal fins which surround the transverse fins create a central recess above the transverse fins which provides an opening to position a driver and also forms pathways through all of the fins by which air can circulate to provide a means for heat dissipation
