AI Technical Summary

Technical Problem

In existing lighting components, the decorative parts are insufficient in retention and complex assemblies, resulting in high costs and manufacturing inconsistencies.

Method used

Repulsive magnets are adopted, and the first pole of the housing magnets and the decorative magnets are oriented relative to each other, and axial force is generated when inserted to maintain the decorative parts, simplifying assembly and reducing costs.

Benefits of technology

Improves the retention of the decorative parts, simplifies the assembly process, reduces costs, and improves manufacturing consistency.

Abstract

A lighting assembly (10) is provided that includes a housing (100), a trim assembly (200), a housing magnet (300), and a trim magnet (400). The housing (100) includes a cavity (102) extending along a central axis (A1). The decoration assembly (200) is inserted into the cavity (102). A housing magnet (300) is mounted within the cavity (102). A first pole (302) of the housing magnet (300) having a first polarity (P1) is oriented towards the central axis (A1). A trim magnet (400) is mounted to the trim assembly (200). The first pole (402) of the trim magnet (400) is oriented away from the central axis (A1) of the housing (100). A first pole (402) of the trim magnet (400) has a first polarity (P1) to repel the housing magnet (302). A first pole (302) of the housing magnet (300) repels a first pole (402) of the trim magnet (400) in a first direction (D1) when the housing magnet (300) is above the trim magnet (400), and repels the first pole (402) of the trim magnet (400) in a second direction (D2) when the housing magnet (300) is below the trim magnet (400) to hold the trim assembly (200).
