Innovation Solution
The downlight apparatus incorporates a back cover with lateral sockets and a metal piece with inverted parts for secure installation, a heat sink for improved heat dissipation, and a separable frame for easy detachment, along with a design that keeps the driver and LED light source at a distance to facilitate heat dissipation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the downlight apparatus uses LED devices for energy efficiency and smaller size, then energy consumption is reduced and compactness is improved, but heat dissipation becomes more challenging
Solution Approach 1:
The housing is divided into a back cover and a frame part that are separable from each other. This segmentation allows the frame part to be detached for installation and removal, facilitating heat dissipation pathways and maintenance access while maintaining the compact LED design
Solution Approach 2:
The patent introduces a lateral dimension for heat dissipation by creating lateral sockets that extend outward from the back cover. These sockets provide additional surface area and pathways for heat management in a direction perpendicular to the main light emission axis
2Ease of manufacture
If the downlight apparatus is designed with a fixed housing structure, then manufacturing simplicity is maintained, but installation reliability and heat dissipation are compromised
Solution Approach 1:
The housing is segmented into a back cover and a frame part that can be separately manufactured and then assembled. This segmentation enables each component to be optimized independently for manufacturing while the assembled structure provides improved installation reliability through the lateral sockets and metal pieces
Solution Approach 2:
Lateral sockets act as intermediary structures that connect the back cover to metal pieces for secure installation. These sockets serve as mediators between the housing structure and the mounting mechanism, providing reliable attachment points while maintaining manufacturing simplicity
3Strength
If the downlight apparatus uses a unified housing structure, then structural integrity is maintained, but installation convenience and maintenance accessibility are reduced
Solution Approach 1:
The housing is divided into a back cover and a frame part that are connected but can be separated. This segmentation maintains structural integrity when assembled while enabling easy installation and removal of the frame part, improving installation convenience and maintenance accessibility
Solution Approach 2:
The connection between the back cover and frame part is designed to be dynamic rather than permanent. The frame part can be attached and detached as needed, providing the flexibility required for easy installation and maintenance while maintaining structural integrity during operation
4Volume of moving object
If the driver and LED light source are placed close together, then device compactness is improved, but heat management and maintenance become more difficult
Solution Approach 1:
The housing is segmented into a back cover containing the driver and a frame part containing the LED light source. This segmentation creates spatial separation between heat-generating components, improving heat management while maintaining overall device compactness through the integrated design
Solution Approach 2:
The LED light source is extracted into a separate frame part that can be independently removed. This extraction allows for separate heat management of the LED components and facilitates maintenance without affecting the driver unit, while maintaining compact overall dimensions

AI summary
A downlight apparatus includes a driver, a LED light source, a back cover and a frame part. The back cover forms a containing space for storing the driver and the LED light source. The back cover has an external side wall fixed with a plurality of lateral sockets. Each lateral socket has an entrance for inserting a corresponding metal piece. The metal piece is fixed to a hook structure when the metal piece is inserted into the lateral socket at a predetermined position from the entrance. The frame part is connected to the back cover. the frame part has an opening for a light of the LED light source emitted from the opening.
