BACKGROUND OF THE INVENTION

People's living standards have improved over time, and so has their demand for better lighting. LED downlights are a type of light fixture that is embedded in the ceiling and shines light downward. They are usually installed around the ceilings of bedrooms, living rooms, and bathrooms. Downlights can create different lighting effects by using different light sources, light guides, and diffuser plates. Moreover, downlights do not take up large space, and they can enhance the softness and coziness of the space. If people want to make the space feel warmer, they can try installing more downlights to reduce the sense of pressure.

In related technology, one of the installation methods for downlights is replacement installation, which is mainly used to replace the original downlights and achieve the same decoration effect. For safety and fire prevention reasons, downlights are usually installed in iron installation barrels. The interior of the barrel is crude, so a decorative ring is added to the edge of the barrel. The decorative rings and downlights on the market are integrated, which makes the whole lamp body too large and not easy to replace. In addition, there are two sizes of barrels on the market, 5 inches and 6 inches, and the current downlights cannot fit both sizes of barrels.

DETAILED DESCRIPTION OF THE INVENTION

The embodiments of the present disclosure will be described below according to the following specific examples. Those skilled can easily understand other advantages and effects of the present disclosure according to contents disclosed by the specification. The present disclosure can also be implemented or applied through other different exemplary embodiments. Various modifications or changes can also be made to all details in the specification based on different points of view and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and the features of the following embodiments can be combined with each other if no conflict will result.

It should be noted that the drawings provided in this disclosure only illustrate the basic concept of the present disclosure in a schematic way, so the drawings only show the components closely related to the present disclosure. The drawings are not necessarily drawn according to the number, shape, and size of the components in actual implementation; during the actual implementation, the type, quantity, and proportion of each component can be changed as needed, and the components' layout may also be more complicated.

The downlight of the present disclosure can solve two problems of the existing downlights: they are not compatible with both 5-inch and 6-inch installation barrels, and they require a large packaging and transportation space due to the fact that the lamp body and the surface ring are integrated and cannot be detached from each other.

The principle and implementation of connecting the spring part with the clamping parts will be described in detail below, assuming that the clamping parts are of the structures shown in FIG. 2a or 2b, so that the skilled person in the field can understand them without creative labor.

Referring to FIG. 1, the downlight 1 comprises a lamp body 11 and a surface ring 12. Referring to FIG. 2a, the lamp body 11 is provided with at least one first clamping part 111 and at least one second clamping part 112. At least one spring part 13 is matingly connected to the lamp body 11 through the first clamping part 111 or the second clamping part 112. The lamp body 11 is detachably connected with the surface ring 12.

This disclosure enables flexible installation of downlights with installation barrels of different sizes by matingly connecting ether the first or second clamping part on the lamp body with the spring part, making the downlight compatible with both 5-inch and 6-inch installation barrels. The problem that existing downlights are not compatible with both 5-inch and 6-inch installation barrels has been solved. By configuring a detachable connection mode between the lamp body and the surface ring, this disclosure enables the separation of the surface ring from the lamp body, which greatly reduces the packaging and transportation space. Moreover, by configuring an infinite-position clamping connection mode between the lamp body and the surface ring, this disclosure enables a 360-degree fastening installation therebetween, making the downlight structure more sturdy and the installation more convenient.

In an embodiment of the present disclosure, referring to FIG. 2a, the lamp body 11 has an opening.

Compared with conventional designs, the spring part and the lamp body of the present disclosure are connected without screws, achieving high-point fixation and low-point limitation, and allow changing the position of the buckle.

Two types of lamp bodies in FIGS. 2a and 2b are connected with the surface ring utilizing the same installation principle, so the following content will only take the lamp body in FIG. 2a as an example for detailed explanation.

In an embodiment of the present disclosure, referring to FIG. 6, a first connecting part 114 is disposed at an outer side wall of the lamp body 11. The first connecting part 114 is of a circular structure, whose substructures are uniformly distributed around the outer side wall of the lamp body 11. The lamp body 11 is matingly connected with the surface ring 12 through the first connecting part 114.

Specifically, the first connecting part 114 is annular shaped.

In an embodiment of the present disclosure, referring to FIG. 7, the surface ring 12 is provided with a second connecting part 121.

The first connecting part disposed at the lamp body is a slot, the second connecting part disposed at the surface ring is a buckle, and the first and second connecting parts can be matingly connected in any relative orientation without using position-limiting structures. This makes the installation easier and faster, and increases the installation efficiency of the downlight.

It should be noted that the above structures of the first and second connecting parts are merely illustrative, and the present disclosure is not limited thereto. In an embodiment of the present disclosure, the first connecting part may be a buckle, and the second connecting part may be a slot.

It should be noted that the above positions of the first and second connecting parts are merely illustrative, and the present disclosure is not limited thereto. In an embodiment of the present disclosure, the first connecting part may be disposed at the inner side wall of the lamp body, and the second connecting part may be disposed at the outer side wall of the surface ring. The structures and positions of the first and second connecting parts can be configured as needed, as long as they can connect the lamp body with the surface ring without using position-limiting structures. Also, the other components inside the downlight should be adjusted according to how the lamp body and the surface ring are connected.

In an embodiment of the present disclosure, referring to FIG. 1, the downlight further comprises a lamp base 14 and a dip switch 15. The lamp base 14 is electrically connected with a light source assembly of the downlight through a first fixing hole 115 on the lamp body 11. The lamp base 14 is electrically connected with the light source assembly through a wiring terminal. The dip switch 15 is electrically connected with the light source assembly through a second fixing hole 116 on the lamp body 11. The user can adjust the color and temperature of the downlight through the dip switch 15.

In an embodiment of the present disclosure, referring to FIG. 1, the downlight further comprises an aluminum substrate 16, a reflector cup 17, and a diffuser plate 18.

The aluminum substrate 16, the reflector cup 17, and the diffuser plate 18 are sequentially placed in an accommodating groove enclosed by the lamp body 11 and the surface ring 12.

In summary, the present disclosure enables flexible installation of downlights with installation barrels of different sizes by matingly connecting ether the first or second clamping part on the lamp body with the spring part, making the downlight compatible with both 5-inch and 6-inch installation barrels. The problem that existing downlights are not compatible with both 5-inch and 6-inch installation barrels has been solved. By configuring a detachable connection mode between the lamp body and the surface ring, this disclosure enables the separation of the surface ring from the lamp body, which greatly reduces the packaging and transportation space. Moreover, by configuring an infinite-position clamping connection mode between the lamp body and the surface ring, this disclosure enables a 360-degree fastening installation therebetween, making the downlight structure more sturdy and the installation more convenient. The surface ring has a concave structure, which allows multiple surface rings to be stacked together during transportation, saving the packaging and transportation. The spring part is L-shaped, which eliminates the need for screws to fix the spring part, achieving high-point fixation and low-point limitation, and allows changing the position of the buckle. This also solves the problem regarding the installation height of the spring part.

The descriptions of the steps or structures corresponding to the drawings are respectively emphasized, and some steps or structures that are not detailed can be referred to the relevant descriptions of other steps or structures.
