Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an expandable LED lamp. Background Art

[0002] A ceiling lamp is a kind of lamp. Since the upper part of the lamp is relatively flat and the bottom is completely attached to the roof during installation, it is called a ceiling lamp. Generally, it consists of a housing, a lighting component and a light-transmitting cover, and is installed on the roof through a hanger.

[0003] At the present stage, the brightness of the ceiling lamp can be controlled to change, but each ceiling lamp has a maximum brightness. When the lighting requirement cannot be met, if the ceiling lamp can be expanded, it can meet a greater lighting requirement. Therefore, how to provide an expandable LED lamp that can be interconnected with high stability and is easy to install has become an urgent problem to be solved. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by this patent application is how to provide an expandable LED lamp with a simple structure, stable connection and easy installation.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An expandable LED lamp includes at least two lamp bodies. Each lamp body includes a lamp base, a lamp shade, a light source mounting plate and a driver. The lamp base includes a frame and a mounting plate fixedly installed inside the frame. The light source mounting plate is fixedly installed at the lower end of the mounting plate. An LED light source is installed on the light source mounting plate. The driver is fixedly installed on the light source mounting plate and is electrically connected to the LED light source. A wire passing hole is formed in the mounting plate. Adjacent lamp bodies are connected through an expansion component.

[0007] In this way, the lamp body is of an existing structure, and adjacent lamp bodies are connected through an expansion component, so that the splicing of the lamp bodies can be realized, better meeting the use requirements, and obtaining an expandable LED lamp.

[0008] Wherein, the frame is rectangular, and expansion components are arranged at both ends of each side of the frame.

[0009] Wherein, the expansion component includes a pressing plate. Two pin shafts are fixed on the frame. The pressing plate is provided with pin holes that are slidably matched with the pin shafts. A limiting block is fixedly installed at the end of the pin shaft far away from the frame. A compression spring is sleeved on the pin shaft, and the compression spring is located between the pressing plate and the limiting block;

[0010] An expansion hole is formed in the frame opposite to the pressing plate. The expansion hole includes a circular hole and a waist-shaped hole that are communicated. A plug that is inserted and matched with the circular hole is fixedly installed on the pressing plate. The diameter of the circular hole is larger than the width of the waist-shaped hole;

[0011] The expansion component further includes an expansion block, which includes a sliding rod slidably engaged with the waist-shaped hole and stoppers fixedly installed at both ends of the sliding rod. The diameter of the stopper is greater than that of the sliding rod, and the stopper is inserted and engaged with the circular hole.

[0012] Among them, three expansion holes are provided in the frame opposite to the pressing plate.

[0013] Among them, heat dissipation holes are provided in the mounting plate.

[0014] In summary, the expanded LED lamp of the present invention has the advantages of simple structure, stable connection, and convenient installation. Description of the Drawings

[0019] The present invention will be further described in detail below with reference to the drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0020] As Figures 1-4 shown, an expanded LED lamp includes at least two lamp bodies 1. The lamp body includes a lamp base, a lamp cover, a light source mounting plate, and a driver. The lamp base includes a frame 2 and a mounting plate 3 fixedly installed inside the frame. The light source mounting plate is fixedly installed at the lower end of the mounting plate. An LED light source is installed on the light source mounting plate. The driver is fixedly installed on the light source mounting plate and is electrically connected to the LED light source. A wire passing hole is provided in the mounting plate, and adjacent lamp bodies are connected by an expansion component 4.

[0021] In this way, the lamp body is of an existing structure, and adjacent lamp bodies are connected through expansion components, so that the splicing of the lamp bodies can be realized, better meeting the usage requirements, and an expandable LED lamp is obtained.

[0022] During implementation, the frame is rectangular, and expansion components are provided at both ends of each side of the frame. This is convenient for manufacturing and use.

[0023] During implementation, the expansion component includes a pressing plate 11. Two pin shafts 12 are fixed to the frame. The pressing plate is provided with pin holes 13 that are slidably matched with the pin shafts. A limiting block 14 is fixedly installed at one end of the pin shaft away from the frame. A compression spring 15 is sleeved on the pin shaft, and the compression spring is located between the pressing plate and the limiting block.

[0024] An expansion hole is provided in the frame opposite to the pressing plate. The expansion hole includes a circular hole 17 and an oval hole 18 that are communicated. A plug 19 that is inserted and matched with the circular hole is fixedly installed on the pressing plate. The diameter of the circular hole is larger than the width of the oval hole.

[0025] The expansion component further includes an expansion block. The expansion block includes a sliding rod 21 that is slidably matched with the oval hole and stoppers 22 fixedly installed at both ends of the sliding rod. The diameter of the stopper is larger than the diameter of the sliding rod, and the stopper is inserted and matched with the circular hole.

[0026] In this way, when using the expansion component to connect adjacent lamp bodies, align the stopper at one end of the expansion block with the circular hole. The stopper pushes the plug and the pressing plate to move, and the compression spring is compressed. When the stopper reaches between the frame and the pressing plate, slide the expansion block so that the sliding rod slides to the end of the oval hole away from the circular hole. At this time, the plug and the stopper are aligned, the pressing plate pushes the stopper to fit with the frame, and the plug limits the position of the stopper to complete the connection. When disassembly is required, pull the pressing plate, the compression spring is compressed, slide the sliding rod into the circular hole, and take out the stopper outward to realize disconnection.

[0027] During implementation, three expansion holes are provided in the frame opposite to the pressing plate. This improves the connection stability of adjacent lamp bodies.

[0028] During implementation, heat dissipation holes (not shown) are provided in the mounting plate. This is convenient for the lamp body to dissipate heat.

[0029] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. In this way, 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.
