Description

Technical Field

[0001] The utility model relates to the field of lighting devices, and in particular to a panel light with a novel locking structure. Background Art

[0002] LED panel lights are a major lighting fixture used in commercial office spaces. The main structural components of existing panels include a frame, a chassis, a light-transmitting plate, and an LED light source. A screw slot with a rectangular cross-section is set on the frame, and then a screw is passed through the chassis and locked into the screw slot to fix the chassis to the frame. The screw thread is rotated on the groove wall in the plane of the screw groove to extrude the thread groove. This structural method has high requirements for the torque of screwing, which can easily cause slipping and is not conducive to repeatedly loosening and locking the screw at the same position. Some existing patent technologies have also made some technical improvements, such as patent 202122146699.0, a panel light, which is tightened by screws and pierces the bottom of the screw groove to enhance the locking and fixing effect of the screw in the groove. This method also fails to completely solve the problem of the degree of tightening of the screw in the groove. Moreover, when the screw locks the chassis to the frame, since the chassis is flat, the screw will move during the screwing process and cannot effectively align with the position of the screw groove, affecting the screwing operation.

[0012] In order to make the purpose, technical solution and advantages of the present application clearer, the present application is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0013] It should be understood that the terms "upward", "downward", "upper" and "lower" are only used to indicate relative relationships, rather than to indicate or imply a specific direction that the device referred to must have, and therefore should not be understood as limiting the present application.

[0014] It should be noted that, in the description of the present application, "several groups" means two or more than two, unless otherwise clearly and specifically defined.

[0015] Combination Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the utility model discloses a panel light with a new locking structure, which is composed of a frame 1, a chassis 2, a light-transmitting plate 3 and an LED light source 4. The panel light may also include other components such as a power supply and a mounting assembly. Among them, the frame 1 is a rectangular ring structure formed by four sections of aluminum profiles made by an extrusion molding process, which are spliced ​​end to end in sequence. The cross-sections of the four sections of aluminum profiles are the same, and the two ends of the aluminum profiles are cut into 45-degree bevels so that the two sections of aluminum profiles can be assembled into a 90-degree right angle when they are butt-joined. The two sections of aluminum profiles are connected and fixed by aluminum sheets and screws. The chassis 2 is made of an aluminum sheet by a stamping and cutting process, and has a concave area in the middle as a placement area for the LED light source 4. The light-transmitting plate 3 is composed of materials such as an acrylic sheet PMMA and a diffusion film attached to the acrylic sheet.

[0016] The frame 1 is provided with a screw fixing groove 11, which is distributed in a ring shape along the frame. The screw fixing groove 11 is a U-shaped groove, and the groove width is about 4mm~6mm. The two side walls of the screw fixing groove 11 are respectively provided with a plurality of groups of tooth grooves 111 recessed toward the inner side of the groove body side wall, and the plurality of groups of tooth grooves 111 are distributed in sequence from the groove of the screw fixing groove 11 to the groove bottom direction at equal intervals. According to the specifications of the screws used, such as the thread pitch, the number of tooth grooves 121 and the groove width of the tooth grooves can be set. The cross section of the tooth groove 111 is rectangular, or it can be triangular or other shapes. The frame 1 is provided with an extended thin wall 12, which is located at the inner side end of the bottom of the frame 1, and the extended thin wall is flush with the bottom end surface of the frame, and the extended thin wall 12 is used to abut against the edge of the chassis 2. The extended thin wall 12 is provided with a boss 121 on the inner side of the screw fixing groove 11, and the boss height is about 2mm~4mm.

[0017] The chassis 2 is provided with a guide groove 21, which is located at the edge of the chassis 2. The cross section of the guide groove is triangular or semicircular, and the size of the groove is approximately the diameter of the screw. The bottom of the guide groove faces the position of the screw fixing groove 11. The chassis 2 is also provided with a protrusion 22, which is a U-shaped bending edge formed by bending the edge of the chassis, and the protrusion direction of the protrusion 22 faces the direction of the extended thin wall 12.

[0018] When assembling the panel light, Figure 1 and Figure 3 As shown, firstly, place the light-transmitting plate 3 against the extended thin wall 12 of the frame 1, then install the LED light source 4 on the inner side of the chassis 2, then align the guide groove 21 on the chassis 2 with the notch position of the screw fixing groove 11 of the frame 1, and finally use the screw to lock the guide groove 21 into the screw fixing groove 11. Figure 2As shown, after the chassis 2 and the frame 1 are locked, the threaded part of the screw is twisted on the tooth groove 111 in the screw fixing hole 11, and part of it is twisted on the side wall of the screw fixing hole 11. Through this combination, the torque for screwing can be reduced, and the problem of screw slippage can be reduced, which can increase the reliability of repeated screwing. In addition, the screw will not be offset under the limiting effect of the guide groove 21, which greatly enhances the efficiency of screwing. After the chassis and the frame are fixed, the raised part 22 on the chassis abuts against the upper surface of the light-transmitting plate 3 to squeeze the extended thin wall 12, and the lower surface of the light-transmitting plate 3 abuts against the boss 121 of the extended thin wall 12. Under the effect of the lever principle, the inner side of the light-transmitting plate 3 will tilt slightly downward with the boss as the fulcrum, and the entire light-transmitting plate will show a phenomenon that the middle part is slightly raised below the panel light, which will enhance the light-emitting effect of the panel light.

[0019] The above-mentioned embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
