Description

Technical Field

[0001] This utility model relates to the field of lighting devices, and in particular to a simple panel light. Background Technology

[0002] Existing direct-emission panel lights typically consist of a frame assembly, a base plate, a diffuser plate, and LED strips. The frame assembly comprises four segments connected end-to-end, with the connections primarily secured using individual corner brackets, making the connection method relatively complex. Simultaneously, the base plate usually employs a concave open-type structure design to provide internal space for the LED strips. This concave open-type structure is generally manufactured using stamping or injection molding of metal parts, a relatively complex process. For example, patent number 202421906356.7 describes an integrated LED panel light whose outer frame is composed of four profile segments, and whose base is an open-type concave groove structure. Utility Model Content

[0003] In order to overcome the defects and shortcomings of the prior art, this utility model provides a simplified panel light.

[0004] This utility model provides a simple panel light, including a profile, an end cap, a base plate, and a diffuser plate. The profile is composed of a first support part and a second support part, as well as an extended thin wall connecting the first support part and the second support part. The profile has a stepped integral structure. The end cap is fixed to the end position of the profile and the two together form a rectangular frame. The base plate and the diffuser plate are respectively fixed to the first support part and the second support part of the profile and together with the rectangular frame form the internal cavity of the panel light. The base plate has a planar structure.

[0005] Furthermore, the first support portion is provided with a locking groove, and the edge of the base plate fits into the locking groove to form a fixed shape.

[0006] Furthermore, a receiving hole is provided at the end position of the second support part, and a pin is provided on the end cover. The pin is inserted into the receiving hole to fix the end cover and the profile.

[0007] Furthermore, the second support frame is provided with a retaining groove, through which the diffuser plate is retained and fixed.

[0008] The beneficial effects of this utility model are as follows: Through structural design, the end cap can be directly connected and fixed to the profile, and the two together form a rectangular frame, which serves as the basic structural framework of the panel light. The profile adopts a stepped integral structure, allowing for a certain gap between the base plate and the diffuser plate after they are fixed to the profile, thus forming the internal cavity of the panel light. This internal cavity is used to house the light-emitting strips and for light distribution design. At this point, the base plate can also be a planar structure. This panel light structure is simple, easy to install, and greatly reduces product costs. Attached Figure Description

[0012] Combination Figure 1 , Figure 2 and Figure 3 As shown, a simple panel light includes a profile 1, an end cap 2, a base plate 3, a diffuser plate 4, and a light strip 5. The profile 1 is an aluminum structure manufactured using an extrusion process; the end cap 2 is a plastic structure manufactured using an injection molding process; the base plate 3 is a planar structure, and its material can be metal or plastic; the diffuser plate 4 is a planar structure, and its material is PMMA or other plastic materials; the light strip 5 consists of several LED beads mounted on a rigid PCB.

[0013] The profile 1 consists of three parts: a first support part 11, a second support part 12, and an extended thin wall 13. Through structural design, the profile 1 has a stepped integral structure, meaning the horizontal height of the first support part 11 is higher than the horizontal height of the second support part 12, and the first and second support parts 11 are not within the same vertical region. The two ends of the extended thin wall 13 are connected to the first and second support parts 11 and 12 respectively, and the extended thin wall 13 is angled. A locking groove 111 is provided on the first support part 11 of the profile 1; the locking groove is an upward-opening U-shaped groove. A receiving cavity 121 is provided on the second support part 12 of the profile 1, extending through the entire profile along the extrusion molding direction. A retaining groove 122 is also provided on the second support part 12; the retaining groove 122 is a horizontally opening U-shaped groove. In this embodiment, there are two profiles 1, placed in a mirror-symmetrical manner.

[0014] The end cap 2 has pins 21 extending outward from its body at both ends, and the cross-sectional shape of the pins 21 matches the inner contour shape of the receiving cavity 121 on the second support 12. In this embodiment, there are two end caps 2, which are placed in a mirror-symmetrical manner.

[0015] When assembling the panel light of this embodiment, the first step is to place two profiles 1 in parallel in a mirror manner; the second step is to insert the pins 21 of one end cap 2 into the receiving cavity 121 of the second support part 12 from one end of the profile 1, and at the same time, use screws to pass through the profile wall on the upper side of the receiving cavity 121 and lock them into the pins 21 to fix the end cap 2 to the profile 1; the third step is to insert the two side edges of the diffuser plate 4 into the retaining grooves 122 of the second support part 12 of the profile 1, and the retaining grooves 122 of the two mirror-placed profiles 1 retain the diffuser plate 4 from both sides inward to fix it; the fourth step is to insert the pins 21 of the other end cap 2 from one end of the profile 1 into the receiving cavity 121 of the second support part 12 of the profile 1. The other end of profile 1 is inserted into the receiving cavity 121 of the second support part 12. Simultaneously, screws are passed through the profile wall on the upper side of the receiving cavity 121 and locked into the pin 21 to fix the end cap 2 to the profile 1. After the connection and fixation of the two end caps 2 and the two profiles 1 are completed, the end caps 2 and the profiles 1 are connected end-to-end to form a rectangular frame. Fifth, the light strip 5 is attached to the lower bottom surface of the base plate 3, and then the two side edges of the base plate 3 are attached to the locking groove 111 of the first support part 11 of the profile 1. Screws are then passed through the base plate 3 and locked into the locking groove 111 to fix the base plate 3 and the profile 1. At this point, the assembly of the entire panel light is complete. The rectangular frame formed by the base plate 3, diffuser plate 4, end caps 2, and profile 1 together forms the closed internal cavity of the panel light. This internal cavity serves as the internal space for the light strip 5 to emit light within the panel light.

[0016] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
