[0031] Reference Figures 1 to 6 The panel light of this utility model embodiment includes a housing 100, a light guide assembly 200, and a light-emitting assembly 300. The housing 100 includes a front frame 110 and a back shell 120, which together form a receiving cavity 101. The front frame 110 is provided with a light-emitting hole 111 communicating with the receiving cavity 101. The light guide assembly 200 is disposed in the housing 100 and located in the receiving cavity 101, and covers the light-emitting hole 111. The light-emitting assembly 300 is disposed in the housing 100 and located in the receiving cavity 101, with the light-emitting side of the light-emitting assembly 300 facing the light guide assembly 200. The side wall or periphery of the front frame 110 is provided with a fixing part 112 that can be bent toward the back shell 120. The fixing part 112 bends and abuts against the side of the back shell 120 away from the light-emitting hole 111, and the fixing part 112 can fix the back shell 120 and the front frame 110 together.

[0032] The light guide assembly 200, the light-emitting assembly 300, and the back shell 120 are assembled into the face frame 110. Then, the face frame 110 is fixed together with the face frame 110 by bending the fixing part 112, so that the fixing part 112 abuts against the side of the back shell 120 away from the light emission hole 111. This eliminates the need to use screws to lock and fix the face frame 110 and the back shell 120 together, thereby simplifying the fixing method of the face frame 110 and the back shell 120 and improving production efficiency.

[0033] In this embodiment, the face frame 110 is provided with a first receiving groove 113, the back shell 120 is located in the first receiving groove 113, the fixing part 112 is located around the opening of the first receiving groove 113, the light emission hole 111 is provided on the bottom wall of the first receiving groove 113, the back shell 120 is provided with a second receiving groove 121, the opening of the second receiving groove 121 faces the light emission hole 111, the light-emitting component 300 is provided on the inner side wall of the second receiving groove 121, the light guide component 200 is located in the second receiving groove 121, and the side wall of the light guide component 200 is disposed opposite to the light-emitting component 300. The above-described structure, with the light-emitting component 300 and the light-guiding component 200 located in the second receiving groove 121 of the back shell 120, and the back shell 120 located in the first receiving groove 113 of the face frame 110, provides good protection for the light-guiding component 200 and the light-emitting component 300, and can reduce light leakage of the shell 100; and the light-emitting component 300 adopts the form of side light emission, which is conducive to forming a gentle lighting light and reducing the glare of the panel light.

[0034] In this embodiment, the thickness of the light guide component 200 is greater than the depth of the second receiving groove 121, and the face frame 110 and the back shell 120 clamp the light guide component 200. The thickness of the light guide component 200 is slightly greater than the depth of the second receiving groove 121, so that part of the light guide component 200 is exposed in the second receiving groove 121. At this time, the face frame 110 and the back shell 120 can clamp and fix the light guide component 200, reducing the risk of the light guide component 200 becoming loose in the receiving cavity 101.

[0035] In this embodiment, the back cover 120 is provided with a wire through hole 122 communicating with the second receiving groove 121. The wire through hole 122 is located on the bottom wall of the second receiving groove 121. The light-emitting component 300 is provided with a wire 310, which passes through the wire through hole 122. The wire through hole 122 is located on the outer edge of the back cover 120. The groove edge of the first receiving groove 113 is recessed and provided with a default groove 114. Specifically, the back cover 120 can be made of plastic, and the face frame 110 is formed by metal stamping. Its edge may be relatively sharp. When installing the panel light, the position of the wire 310 needs to be repeatedly adjusted, and the wire 310 may come into contact with the edge of the nearby face frame 110. Therefore, the default groove 114 is provided to avoid the wire 310, so that the wire 310 is not easily cut by friction from the edge of the nearby face frame 110, thereby improving the durability of the product.

[0036] In this embodiment, the face frame 110 and the back shell 120 are rectangular. The back shell 120 has wire-passing holes 122 at its two corners, and all corners of the face frame 110 have default slots 114. The presence of default slots 114 at all corners of the face frame 110 ensures that when the back shell 120 is installed in the first receiving slot 113, the wire 310 can always be avoided by the default slots 114, making the installation angle relatively flexible and convenient.

[0037] In this embodiment, the side of the back cover 120 facing away from the light emission hole 111 is higher than the opening of the first receiving groove 113. This structure further reduces the risk of the wire 310 contacting and rubbing against the edge of the opening of the first receiving groove 113, further reducing the risk of the wire 310 being cut by friction, and improving the product's durability.

[0038] Specifically, the light-emitting component 300 is a light strip 320, and wires 310 are connected to both ends of the light strip 320. It is conceivable that in other embodiments, the light-emitting component 300 may also be a structure such as a lamp board, and those skilled in the art can configure it according to actual needs.

[0039] In this embodiment, the face frame 110 is a metal part, including a main body 115. The outer periphery of the main body 115 is bent towards the back shell 120 to form a side plate portion 116. The side plate portion 116 and the main body 115 enclose a first receiving groove 113. The edge of the side plate portion 116 is bent to form a fixing portion 112. The face frame 110 directly forms the side plate portion 116 and the fixing portion 112 by bending. The first receiving groove 113 and the fixing portion 112 can be formed by punching and bending a metal sheet, which has a simple structure and high material utilization.

[0040] Specifically, the side plate portion 116 is strip-shaped, and the fixing portion 112 is a small plate-shaped part. It is conceivable that in some other embodiments, the fixing portion 112 may also be strip-shaped.

[0041] Specifically, the face frame 110 is a single piece, formed by stamping and bending sheet metal, allowing the fixing part 112 to be bent. It is conceivable that in other embodiments, the face frame 110 may also be formed by injection molding a metal sheet and plastic as a single piece, with the metal sheet forming the bendable fixing part 112.

[0042] In this embodiment, the main body 115 is rectangular, and four side plates 116 are provided, with a gap 117 between the ends of two adjacent side plates 116. Since the face frame 110 is formed by punching and bending a metal sheet in this embodiment, the gap 117 between the ends of two adjacent side plates 116 avoids the risk of interference between different side plates 116 when the face frame 110 is bent to form the side plates 116, thus facilitating the bending of the face frame 110 to form the side plates 116.

[0043] In this embodiment, the faceplate 110 is provided with a plurality of fixing parts 112, all of which are arranged at intervals around the outer periphery of the back shell 120. The multiple fixing parts 112 arranged at intervals facilitate the abutment and fixation of the back shell 120 at various points on the outer periphery, thereby improving the installation stability of the back shell 120.

[0044] In this embodiment, the light guide assembly 200 includes a light guide plate 210 and a diffuser plate 220, which are stacked together. The light guide plate 210 is located on the side of the diffuser plate 220 opposite to the light emission hole 111. The light guide assembly 200, including the light guide plate 210 and the diffuser plate 220, allows light emitted from the light-emitting component 300 to pass sequentially through the light guide plate 210 and the diffuser plate 220, forming a relatively uniform and gentle lighting effect and reducing glare.

[0045] It is conceivable that in other embodiments, the light guide component 200 may also be other types of light guide structures, which can be specifically configured according to actual needs by those skilled in the art.

[0046] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
