Description

Technical Field

[0001] This utility model relates to the field of lighting manufacturing technology, and more specifically, to an LED flat panel light. Background Technology

[0002] Some commercially available LED panel lights use a method of mounting LED strips onto a housing, then sealing the housing with a light guide plate at the port. This type of LED panel light has a simple structure. However, these lights suffer from the problem of LED strips detaching due to high heat after prolonged use. Therefore, another type of LED panel light has been developed to solve this problem. This type uses side sliding grooves in the housing to allow the LED strips to slide sideways. However, this method still suffers from the inconvenience of replacing damaged LED strips, resulting in an overall unsatisfactory performance. Therefore, this invention proposes an LED panel light. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an LED flat panel light that features a non-detachable LED strip and convenient replacement and maintenance of the LED strip.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to an LED flat panel light, including a lampshade and a light guide plate disposed at the opening of the lampshade. A first groove is formed on the back side of the lampshade. The bottom of the first groove is formed with a plurality of LED strip mounting grooves extending along the width direction of the lampshade and spaced apart along the length direction of the lampshade. An LED strip is embedded in the LED strip mounting groove. The bottom of the LED strip mounting groove is provided with a lamp hole for the LED beads on the LED strip to extend out. A cover plate is detachably connected to the first groove. The cover plate is provided with a pressure strip that abuts against the LED strip. The pressure strip extends along the length direction of the LED strip mounting groove.

[0005] The present invention is further configured such that: the cross-section of the pressure strip is a transverse U-shaped structure; the pressure strip is composed of an upper pressure plate, a lower pressure plate and a C-shaped piece connected between the upper pressure plate and the lower pressure plate, the upper pressure plate is connected to the cover plate and the lower pressure plate abuts against the LED light strip.

[0006] The present invention is further configured such that: the cover plate is provided with a wire hole for matching the pressure strip.

[0007] The present invention is further configured such that: a screw hole is provided on the cover plate, and a threaded hole matching the screw hole is provided on the lampshade, and a screw passing through the screw hole is threaded into the threaded hole.

[0008] The present invention is further configured such that the spacing between two adjacent LED strip mounting slots is equal.

[0009] In summary, the present invention has the following beneficial effects: The LED flat panel light involved in the present invention, through the setting of the LED strip mounting groove placed outside the lamp cover, can facilitate the disassembly and replacement of the LED strip without the need for adhesive. The LED strip will not fall off due to the melting of adhesive when it is lit for a long time. It is safe and reliable to use, and the replacement of the LED strip is also convenient. The overall function is complete and the practicality is strong. Attached Figure Description

[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See Figure 1 and Figure 2 As shown, the LED flat panel light involved in this embodiment includes a lampshade 1 and a light guide plate (not shown) disposed at the opening of the lampshade 1. A first groove 2 is formed on the back side of the lampshade 1. A plurality of LED strip mounting grooves 3 extending along the width direction of the lampshade 1 and spaced apart along the length direction of the lampshade 1 are formed at the bottom of the groove. An LED strip 4 is embedded in the LED strip mounting groove 3. A lamp hole 5 is opened at the bottom of the LED strip mounting groove 3 for the LED beads on the LED strip to protrude. A cover plate 6 is detachably connected to the first groove 2. A pressure strip 7 is provided on the cover plate 6 to abut against the LED strip. The pressure strip 7 extends along the length direction of the LED strip mounting groove 3.

[0016] Furthermore, the cross-section of the pressure strip 7 is a transverse U-shaped structure; the pressure strip 7 is composed of an upper pressure plate 71, a lower pressure plate 72 and a C-shaped piece 73 connecting the upper pressure plate and the lower pressure plate, the upper pressure plate 71 is connected to the cover plate 6, and the lower pressure plate 72 abuts against the LED light strip 4.

[0017] Furthermore, the cover plate 6 has a screw hole 9, and the lampshade 1 has a threaded hole 10 that matches the screw hole. A screw 11 that passes through the screw hole is threaded into the threaded hole 10.

[0018] Furthermore, the spacing between two adjacent LED strip mounting slots 3 is equal.

[0019] In this implementation, firstly, take an equal number of LED strips 4 as the number of LED strip mounting slots 3, and embed them one by one into the LED strip mounting slots 3 until the LED beads protrude from the lamp holes 5. Then, take out the cover plate 6 and install it onto the first groove 2 until the pressure strip 7 presses against the back side of the LED strip 4 embedded in the corresponding LED strip mounting slot 3. Finally, fix it with screws 11 passing through screw holes 9, completing the connection between the lamp cover 1 and the cover plate 6. If it is necessary to replace the LED strip 4, simply remove the cover plate 6.

[0020] The pressure strip 7, with its horizontally U-shaped cross-section, provides elastic compression to the LED light strip 4.

[0021] Example 2

[0022] See Figure 1 and Figure 2 As shown, the LED flat panel light involved in this embodiment is further configured, based on embodiment 1, with the cover plate 6 having a wire hole 8 for matching pressure strip.

[0023] In this embodiment, the wire hole 8 serves two purposes: firstly, it is used for the passage of wires for electrically connecting the LED light strip 4, and secondly, it can be used as a heat dissipation hole.

[0024] The LED flat panel light involved in this utility model, through the setting of the LED strip mounting groove placed outside the lamp cover, can facilitate the disassembly and replacement of the LED strip without the need for adhesive. The LED strip will not fall off due to the melting of adhesive when it is lit for a long time. It is safe and reliable to use, and the replacement of the LED strip is also convenient. The overall function is complete and highly practical.
