Description

A kind of LED surface mounted downlight

Technical Field

The utility model relates to the technical field of downlights, in particular to an LED surface-mounted downlight.

Background Art

Due to the advantages of high brightness, low energy consumption, environmental protection and stable performance, LED lamps have been widely used in lighting fields such as homes, shopping malls, office areas and schools. LED downlights are a type of lamp that is more focused than ordinary LED lamps. They are generally used for general lighting or auxiliary lighting to create a lighting atmosphere. LED downlights can be installed in a surface-mounted or embedded manner to maintain the overall unity and perfection of architectural decoration.

When the LED downlights on the market are installed in a surface-mounted manner, the hanger is first fixed on the ceiling, and then the downlight is connected to the hanger with screws. When it needs to be replaced later, it is necessary to climb up and use a screwdriver or screw machine to disassemble it, which is inconvenient, time-consuming and labor-intensive.

Summary of the invention

In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a simple and stable LED surface-mounted downlight that does not require any tools at a later stage and is easy to install and use.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

An LED surface-mounted downlight comprises a hanger and a downlight body;

The hanger is fixedly connected to the ceiling, and has four hanging arms evenly distributed around the hanger. The outer ends of the hanging arms have arc-shaped plates that bend and extend downward, and any two opposite arc-shaped plates are provided with locking holes.

Two locking structures are installed in the lamp housing of the downlight body. The locking structures are used to drive the locking pin to move. The locking pin can be plugged and matched with the locking hole.

In this way, during installation, the hanger is fixed on the ceiling with a screwdriver or other tool, and then the downlight body is held and moved to the outside of the hanger, and the locking structure drives the locking pin to engage with the locking block to complete the installation. When disassembly is required, the locking structure drives the locking pin to move to the outside of the locking hole, and the downlight body can be disassembled.

Among them, the locking structure includes a mounting tube fixedly installed in the lamp housing, a limiting plate slidingly cooperated in the mounting tube, sliding columns are fixed at both ends of the limiting plate, a sealing plate is fixed at the inner end of the mounting tube, the lamp housing and the sealing plate are both provided with sliding holes slidingly cooperated with the sliding column, a compression spring is sleeved on the outer side of the sliding column, the compression spring is located between the limiting plate and the sealing plate, the sliding column passes through the sealing plate and is fixed with a locking plate, and the locking pin is fixedly installed on the side of the locking plate facing the lamp housing.

Wherein, two limit blocks are fixed in the body of the downlight, and the limit blocks are located between the two locking structures.

Wherein, the hanger, the suspension arm and the arc-shaped plate are integrally formed.

Wherein, the hanger and the suspension arm are both provided with mounting holes, and the hanger and the suspension arm are both fixedly connected to the ceiling by expansion screws.

In summary, this LED surface mounted downlight has the advantages of no need for tools in the later stage, easy installation and use, and simple and stable.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings. In the description of the utility model, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description. In the absence of any contrary description, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

As shown in Fig. 1-4, an LED surface mounted downlight comprises a hanger 1 and a downlight body 2;

The hanger is fixedly connected to the ceiling, and has four arms evenly distributed around the hanger. The outer ends of the arms have arc-shaped plates 4 that bend downward and extend, and any two opposite arc-shaped plates have locking holes 5.

Two locking structures are installed in the lamp housing of the downlight body. The locking structures are used to drive the locking pin 6 to move. The locking pin can be plugged into and matched with the locking hole.

In this way, during installation, the hanger is fixed on the ceiling with a screwdriver or other tool, and then the downlight body is held and moved to the outside of the hanger, and the locking structure drives the locking pin to engage with the locking block to complete the installation. When disassembly is required, the locking structure drives the locking pin to move to the outside of the locking hole, and the downlight body can be disassembled.

During implementation, the locking structure includes a mounting tube 7 fixedly mounted in the lamp housing, a limit plate 8 slidingly fitted in the mounting tube, a slide column 9 fixed at both ends of the limit plate, a sealing plate 10 fixed at the inner end of the mounting tube, the lamp housing and the sealing plate are provided with sliding holes slidingly fitted with the slide column, a compression spring 11 is sleeved on the outer side of the slide column, the compression spring is located between the limit plate and the sealing plate, the slide column passes through the sealing plate and is fixed with a locking plate 12, and the locking pin is fixedly mounted on the side of the locking plate facing the lamp housing. During installation, the slide column is pressed inward to drive the limit plate and the locking pin to move inward, and the downlight body is pushed to the outside of the hanger. When the locking hole is facing the locking pin, the slide column is released, and under the action of the compression spring, the limit plate and the locking pin are reset, and the locking pin is inserted into the locking hole to complete the connection and locking. During disassembly, the locking pin is pressed inward to disengage the locking pin from the locking block, and then the downlight body can be removed.

During implementation, two limit blocks 13 are fixed in the body of the downlight, and the limit blocks are located between the two locking structures. The hanger has four arms, and when the arms abut against the limit blocks, the locking pins face the locking holes, and the limit blocks are set to provide a prompt of being in place.

During implementation, the hanger, the suspension arm and the arc-shaped plate are integrally formed, which is convenient for production and processing.

During implementation, the hanger and the arm are both provided with mounting holes, and the hanger and the arm are both fixedly connected to the ceiling by expansion screws, so as to improve the installation reliability of the hanger.

Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
