Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims foreign priority benefits under 35 U.S.C. § 119 from Chinese Patent Application No. 202310929132.1, filed Jul. 26, 2023, the content of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure belongs to the technical field of down lamps, and particularly, to a four-in-one down lamp with a rotatable mounting disk structure and an implementation method thereof.

BACKGROUND

A down lamp is a lighting fixture that is embedded in a ceiling and emits light downwards. The down lamp has a compact structure, is convenient to mount, and is widely used in home lighting and lighting and atmosphere creation in public places such as shopping malls and hotels. North America down lamps are used commonly, and their simple style and fast mounting methods have attracted the attention of many customers.

The mounting methods for the North American down lamps include mounting with a J-box, drum-free mounting, and mounting with an iron drum. The most common mounting method is mounting with a four-inch iron drum and a six-inch iron drum. In recent years, light-emitting diode (LED) down lamps integrated with two or three mounting methods have appeared in the market, which have the following drawbacks:

• • 1. This LED down lamp is not simultaneously applied to both the four-inch iron drum and the six-inch iron drum.
  • 2. A mounting disk of a J-BOX and a lamp body are mounted by using elastic sheets. This occupies the space of the J-BOX. Especially, a small-sized BOX has an extremely small wiring space, which may press a lamp and cause the lamp to not be completely sucked to a ceiling.
  • 3. Accessories for mounting with an iron drum or new mounting are directly locked onto a lamp body, and a mounting disk needs to be discarded, resulting in waste. This does not comply with the environmental protection concept.

SUMMARY

The present disclosure aims to provide a four-in-one down lamp with a rotatable mounting disk structure, so as to solve the problems mentioned in the background. The four-in-one down lamp with a rotatable mounting disk structure according to the present disclosure has the characteristics of satisfying four common mounting scenarios of a North American down lamp and greatly reducing the stocking pressure of a client.
