Rotatable Mounting Disk for Four-in-One Down Lamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED down lamps for North America are not compatible with both four-inch and six-inch iron drums, occupy space in J-BOXes due to elastic sheet mounting, and result in waste due to the need for discarding mounting disks during iron drum mounting.
Innovation Solution
A four-in-one down lamp with a rotatable mounting disk structure that includes a lamp body and a mounting disk, allowing for connection through fastening edges and steps, and accommodating different mounting members such as butterfly elastic sheets, V-shaped springs, and power box components to satisfy various mounting scenarios without occupying additional space or causing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED down lamps are integrated with multiple mounting methods, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The mounting disk is designed with multiple mounting interfaces that can accommodate different mounting methods (J-BOX, iron drum, new mounting) through a single unified structure. The disk includes threaded holes for J-BOX mounting, clamping structures for iron drum mounting, and integrated features for new mounting methods, allowing one component to serve multiple mounting functions
Solution Approach 2:
The patent combines multiple previously separate mounting components (mounting disk, elastic sheets, fasteners) into a single integrated mounting disk assembly. This merging reduces the number of separate parts while maintaining compatibility with multiple mounting methods, thereby improving adaptability without proportionally increasing complexity
2Ease of operation
If elastic sheets are used to mount the lamp body to the J-BOX, then the ease of operation is improved, but the volume of the J-BOX is reduced
Solution Approach 1:
The elastic sheets are extracted from the J-BOX interior and repositioned to the exterior, where they are mounted on the mounting disk rather than occupying space within the J-BOX. This extraction allows the J-BOX to maintain its full wiring volume while still providing the ease of operation benefits of elastic sheet mounting
3Ease of manufacture
If mounting disks are discarded after iron drum mounting, then the ease of manufacture is improved, but the loss of substance increases
Solution Approach 1:
Instead of discarding the mounting disk after use, the design allows it to be recovered and reused for subsequent lamp installations. The mounting disk is made durable and is designed to remain intact after removing one lamp, enabling it to be used for mounting the next lamp, thereby reducing material waste while maintaining manufacturing simplicity

AI summary
A four-in-one down lamp with a rotatable mounting disk structure includes a lamp body and a mounting disk; the lamp body includes an outer shell; a concave cavity is arranged on an upper surface of the outer shell; a side wall of the concave cavity is connected to two symmetrically arranged fastening edges; two steps corresponding to the fastening edges are connected to a periphery of the mounting disk; and the mounting disk is further formed with screw holes and positioning slots which are configured to be connected to a mounting member. Further disclosed is an implementation method of a four-in-one down lamp with a rotatable mounting disk structure. The mounting disk and the lamp body are connected to each other through cooperation between the fastening edges and the steps. The four-in-one down lamp is mounted rotatably, so that elastic sheets are eliminated, and spaces in a driving box and for wiring are not occupied. Different mounting members are connected through screws on the mounting disk to satisfy four common mounting scenarios of a North American down lamp, so that the stocking pressure of a client is greatly reduced, and the application range is large.
