The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 4, the present application provides a direct type panel lamp mounting structure 100 including a lamp body and a keel fixing the lamp body. The lamp body is provided with a frame 20 at the periphery, the frame is fixed on the keel through a plurality of fasteners 10, and the surface of the frame is in conformity with the keel.

The lamp body further includes a back plate 30, a diffusion plate 40, and at least one light bar 50, wherein the back plate 30 is a housing-like structure made of a metal plate material by deformation, the housing-like structure includes a central region 31 and an edge region 32 surrounding the central region 31, and in order to increase a distance between the back plate 30 and the diffusion plate 40, the central region 31 is upwardly arched and configured to mount and fix the light bar 50.

The light bar 50 comprises a substrate, LED lamp beads fixed on the substrate and a lens covered on the LED lamp beads. The light bar 50 is fixed to the side of the central area 31 of the back panel 30 facing the diffuser panel 40. The diffusion plate 40 has a light transmitting function, and a plurality of LED point light sources formed after light diffusion form a uniform surface light source.

The frame 20 is formed by splicing a plurality of frame strips 21, each frame strip 21 has a first mounting surface 22 and a second mounting surface 23 at different heights, the edge of the diffusion plate 40 is lapped on the lower first mounting surface 22, and the edge area 32 of the back plate 30 is lapped on the higher second mounting surface 23 and is fixed by fastening screws.

As mentioned above, the back plate 30 is made of a metal plate, and the light bar 50 is installed in the central area 31 of the back plate 30, and under the action of gravity, the central area 31 of the back plate 30 will be caused to collapse, so that the corner portions of the back plate will be tilted upwards, and if the strength of the frame 20 is not enough, the frame 20 will be pulled to deform and tilt, so that a gap exists between the frame 20 and the keel.

And considering that when the lamp body is rectangular and has a longer length, the tower under the central area 31 of the back plate 30 will bring the two ends of the panel lamp in the length direction to deform more seriously under normal conditions.

In order to solve the technical problem, in the present embodiment, as shown in fig. 1, in an installation structure 100 of a direct type panel light, a light body is directly installed on a keel through a fastener 10, and external force is applied to two ends of a length direction of an easily deformable frame 20, and the external force is opposite to the upward tilting of the frame 20 caused by a downward collapse of a back plate 30, so as to ensure that the light body can be installed on the keel in a fitting manner.

In some embodiments, fastener 10 includes an anchor disposed on bezel 20, or a mounting hole 241 opened on bezel 20, and a fastening bolt engaged with mounting hole 241, as shown in fig. 1.

Specifically, when installing the lamp body to fossil fragments, also seted up the mounting hole according to the position of mounting hole 241 on frame 20 on the corresponding position on fossil fragments, aim at corresponding fossil fragments with frame 20 again and place. The rod part of the fastening bolt sequentially penetrates through the frame 20 and the mounting hole 241 on the keel, the head part of the bolt is left on one side, back to the keel, of the frame 20, and then the nut is screwed with the frame 20 from the other end of the screw rod, so that the frame 20 has an external force which is upward along the length direction of the screw rod, and the force of deformation of the frame 20 caused by the lower couch of the backboard 30 is offset.

In some embodiments, the mounting holes 241 or the anchoring elements are disposed on the top surface 24 of the bezel 21 (in the embodiment, shown as mounting holes) on both sides of the width of the bezel 20. The mounting holes 241 or anchoring elements are distributed in pairs on opposite sides of the frame 20 so that the top surface 24 of the frame 20 is flush with the keel when the frame 20 is directly secured to the keel.

At least two pairs of mounting holes 241 or anchoring elements are distributed along the length of the rim 20, considering that both ends of the rim 20 are more severely deformed.

Preferably, the two pairs of mounting holes 241 or anchor mounting points are symmetrically located near the tip. When the central area of the backboard 30 is collapsed and deformed to drive the frames 20 at the two sides to tilt, the mounting points at the two sides can be offset in directions to prevent the frames 20 at the two sides from tilting.

In this embodiment, each pair of mounting holes 241 or anchors are equally spaced along the length of the frame 20 to provide a more balanced load bearing engagement of the keel with the frame 20.

In the present application, as shown in fig. 5 and 6, the support strength of the entire back plate 30, especially the support strength of the edge region 32, is increased by modifying the structure of the back plate 30 itself to reduce the amount of deformation of the edge region 32, and connecting a transition region 33 between the central region periphery and the edge region 32. So that the edge area 32 is always in a flat state, and the frame 20 is prevented from being pulled, so that the frame 20 is deformed, and further, the direct type panel lamp is applied to the keel on the ceiling in a contact manner, and no gap is generated.

In the present embodiment, the transition region 33 includes a first transition region 331 and a second transition region 332.

Specifically, the first transition area 331 is located at the periphery of the central area 31 and presses the edge of the diffuser plate 40 against the first mounting surface 22. The first transition area 331 is formed by extending horizontally from the periphery of the central area to the periphery and presses against the edge of the diffusion plate 40. Because the back plate 30 has a certain elasticity, when the first transition area 331 abuts against the diffusion plate 40, the entire transition area 33 is elastically deformed, so that the first transition area 331 applies pressure to the diffusion plate 40, and the first transition area 331 and the first mounting surface 22 cooperate to clamp the edge of the diffusion plate 40, so as to prevent the edge of the diffusion plate 40 from being bent, thereby preventing the central portion of the diffusion plate 40 (the geometric center of the diffusion plate 40 or the position close to the geometric center of the diffusion plate 40) from collapsing downward.

Specifically, the second transition area 332 is located at the periphery of the first transition area 331 and extends upward to the second mounting surface 23 and connects with the edge area 32.

To further address the problem of deformation of the bezel, in some embodiments, an upwardly projecting bead 34 is connected between the second transition region 332 and the edge region 32. The ribs 34 cooperate with the transition areas 33 to increase the support strength of the entire back plate 30, particularly the edge areas 32. When the light body is mounted to the keel, the amount of deformation of the edge region 32 can be reduced so that the edge region 32 is always in a flat condition. Avoid its pulling frame 20, make frame 20 take place deformation, and then make the lamp body top surface also be the top surface 241 of frame 20 and fossil fragments contact application of plaster, the gap can not appear.

Because backplate 30's emergence deformation is often inevitable, only alleviates deformation to the improvement of backplate 30 self structure and has started certain effect, so in this application, directly fix frame 20 on fossil fragments to the frame 20 deformation that causes under the backplate 30 is offset to the mode that increases external force. And according to the difference of the length and the strength of the frame 20 and the strength of the back plate 30, a plurality of pairs of mounting holes 241 or anchoring pieces can be arranged on the frame 20 to increase the strength of the external force, so as to always ensure that the top surface 14 of the frame 20 is always in line with the keel.

In some embodiments, as shown in fig. 7, the cross section of the frame strip 21 is an L-shaped structure, and includes a horizontal portion 25 and a vertical portion 26, the edge of the diffuser plate 40 and the edge of the back plate 30 are overlapped on the horizontal portion 25, and the vertical portion 26 encloses a limited space for shielding the mounting structure of the edge of the back plate 30, so as to achieve decoration and certain protection.

In some embodiments, to increase the strength of the profile, the inside thickness of the corner of the frame strip 21 is increased to form a thickened portion 27, so as to form a step structure in the horizontal portion 25, and the first mounting surface 22, the second mounting surface 23 and the top surface 14 are located at the step structure and the horizontal portion 25, respectively. To save material, in some embodiments, thickened portion 27 is a hollow structure.

In some embodiments, mounting holes 241 are formed on the third plane of the step and corresponding to the horizontal portion 25, so that bolts can pass through the thickened portion 27 to fix the frame 20 to the keel.

For ease of installation, the frame strip 21 is provided with screw slots 281 arranged along its length. In some embodiments, a middle portion of the upper surface of the horizontal portion 25 has a first vertical fold 28, and a gap between the first vertical fold 28 and the step structure forms the screw slot 281, and the top surface of the vertical fold supports the edge region 32.

In some embodiments, the upper surface of the horizontal portion 25 has a second vertical fold 29 near the edge of the diffuser plate 40, and the second vertical fold 29 on each edge strip 21 is connected to each other to form an area for placing the diffuser plate 40.

In some embodiments, the fastening screw has a plurality distributed in succession along the path of extension of the edge region 32.

In some embodiments, the portion of the edge region 32 overlapping the bezel 20 is parallel to the bottom wall 351, and the bottom wall 351 is higher than the edge region 32. After the direct type panel light is installed, the bottom wall 351 is horizontally disposed, and the portion of the corresponding edge area 32 overlapping the frame 20 is also horizontally disposed.

To facilitate positioning of the light bars 50, in some embodiments, as shown in fig. 3, the bottom wall 351 is provided with grooves for positioning the light bars 50 in a criss-cross manner. In order to facilitate the processing of the groove on the back panel 30, the central region 31 of the back panel 30 is stamped to form a plurality of protrusions 311 facing the cavity 35, the groove is formed between adjacent protrusions 311, each light bar 50 is arranged in parallel, therefore, the protrusions 311 should also be arranged in parallel, and the gap between adjacent protrusions 311 is used for mounting the light bars 50, so that the light bars 50 are generally in a straight strip structure. Of course, the light bar 50 can also be a serpentine structure.
