Description

A plastic frame for surface-mounted LED lamp

Technical Field

The utility model relates to the technical field of lighting fixtures, in particular to a surface-mounted plastic frame for an LED lamp.

Background Art

The most commonly used LED lights are panel lights, which can be installed in two ways: embedded installation and surface installation. Embedded installation requires opening a hole in the ceiling. After installation, the gap between the hole and the panel light needs to be filled, which is very inconvenient. Therefore, surface installation is currently mostly used, that is, fixing the panel light and the plastic frame to the ceiling with screws.

The existing plastic frame includes four hollow pipes with rectangular cross-sections. Four corner connectors are inserted into the ends of the pipes to form a rectangular structure. The corner connectors are provided with mounting holes. Screws are passed through the mounting holes of the panel lights and the corner connectors to connect to the ceiling. However, the plastic frame with this connection method is very easy to fall apart. The pipes and the corner connectors are only simply plugged in and can be pulled out at will. The stability is poor and it is not convenient to use.

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 surface-mounted plastic frame for LED lamps that is easy to connect, highly stable, and easy to dissipate heat.

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

A surface-mounted plastic frame for an LED lamp comprises four frames and four corner connectors.

The frame has a U-shaped cross section and is opened outward, an end connector is fixed to the end of the frame, the end connector is hooked to the corner connector, and a mounting hole is provided on the corner connector;

The end connector includes an end plate and a hook. The end plate is fixedly connected to the frame. The hook is in an inverted L shape and is installed on the upper end of the outer side of the end plate. The corner connector is provided with a hanging groove for hanging with the hook.

In this way, during installation, the end connector is hooked with the corner connector through the hook and the hanging groove, and then the LED lamp and the corner connector are fixed to the ceiling through bolts. The setting of the hook and the hanging groove enables the frame and the corner connector to form a stable connection relationship, which can only be disassembled in the vertical direction and cannot be disassembled in the horizontal direction, thereby improving the reliability and stability of the connection. The frame cross section is U-shaped and the opening is set outward, which can improve the heat dissipation effect.

Among them, at least two insertion holes are opened on the hook, and the corner connector is fixed with an insertion rod that can be plugged and matched with the insertion holes directly opposite to the insertion holes.

Among them, at least two reinforcement blocks of different lengths are fixed outwardly to the hook, and the corner connector is provided with a notch for plugging and matching with the reinforcement block.

Wherein, a plurality of heat sinks arranged at intervals are fixed in the opening of the frame.

Wherein, the frame is connected to the end plate by welding.

Wherein, the end plate, the hook and the reinforcement block are integrally formed.

In summary, the LED lamp surface-mounted plastic frame has the advantages of convenient connection, high stability and convenient heat dissipation.

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. 1-5 , a plastic frame for surface-mounted LED lamps includes four frames 1 and four corner connectors 2.

The frame has a U-shaped cross section and is opened outward. An end connector 3 is fixed to the end of the frame. The end connector is connected to a corner connector. A mounting hole 4 is provided on the corner connector.

The end connector includes an end plate 5 and a hook 6. The end plate is fixedly connected to the frame. The hook is in an inverted L shape and is installed on the upper end of the outer side of the end plate. The corner connector is provided with a hanging groove 7 for hanging with the hook.

In this way, during installation, the end connector is hooked with the corner connector through the hook and the hanging groove, and then the LED lamp and the corner connector are fixed to the ceiling through bolts. The setting of the hook and the hanging groove enables the frame and the corner connector to form a stable connection relationship, which can only be disassembled in the vertical direction and cannot be disassembled in the horizontal direction, thereby improving the reliability and stability of the connection. The frame cross section is U-shaped and the opening is set outward, which can improve the heat dissipation effect.

During implementation, at least two insertion holes 8 are provided on the hook, and the corner connector is fixed with an insertion rod 9 which can be plugged and matched with the insertion holes, so as to improve the connection strength.

During implementation, at least two reinforcement blocks 10 of different lengths are fixed outwardly to the hook, and the corner connector is provided with a notch 11 for plugging and matching with the reinforcement block, thereby further increasing the connection strength.

During implementation, a plurality of heat sinks 12 are fixed in the opening of the frame at intervals to increase the contact area with the air and improve the heat dissipation effect.

During implementation, the frame is connected to the end plate by welding, which is convenient for quick connection.

During implementation, the end plate, the hook and the reinforcing block are integrally formed, which is convenient for manufacturing.

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.
