[0003] The light of the panel lamp forms a uniform planar light-emitting effect after passing through a light guide plate with a high light transmittance, with good illuminance uniformity, soft light, being comfortable without losing brightness, and can effectively relieve eye fatigue.

[0004] A Chinese utility model patent with an application number of 202320381935.3 discloses an ultra-thin three-proof ceiling lamp, which includes a lamp housing. An LED light strip that emits light towards the inside of the lamp housing is installed on the inner side wall of the lamp housing. A reflector, a light-transmitting plate and a light diffusing plate are successively installed on the inner side of the lamp housing from top to bottom. The light-transmitting plate is arranged inside the LED light strip. A face ring that abuts against the light diffusing plate is clamped at the bottom of the lamp housing. Specifically, a plurality of card slots are arranged on the outer side of the lamp housing, and clamping blocks corresponding to the card slots are arranged on the inner side of the face ring. The cooperation of the card slots and the clamping blocks facilitates the stable clamping and installation of the face ring.

[0005] Although in the above structure, the face ring holds up the edge part of the light diffusion, and then the face ring is clamped with the lamp housing, and screws are not needed in the assembly process; however, there are many structures and the assembly process is also relatively complex, resulting in too high production costs. Therefore, the utility model has made improvements in the structure of the panel lamp for this problem. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a side-emitting panel lamp with a screwless structure that has no frame and low cost according to the current situation of the prior art.

[0007] The technical solution adopted by the utility model to solve the above technical problem is as follows: The side-emitting panel lamp with a screwless structure includes a housing, a light-emitting component and a diffusion plate. The light-emitting component is arranged below the housing, and the diffusion plate is arranged below the light-emitting component. The diffusion plate includes a main board and a second annular wall extending upward from the edge of the main board. The upper edge of the second annular wall extends towards the inside of the main board and has a lapping part that laps on the upper surface of the housing. The housing and the light-emitting component are limited between the lapping part and the main board.

[0008] To reasonably arrange the positions of various components inside the housing, the housing includes a top shell and a first annular wall extending downward from the edge of the top shell; the light-emitting assembly includes a lamp board and a light guide plate. The lamp board is disposed inside the first annular wall, and lamp beads are provided inside the lamp board; the light guide plate is horizontally disposed above the main board, and the side wall of the light guide plate corresponds to the position of the lamp beads. In this embodiment, the square housing extends downward with four groups of first annular walls, and the lamp board is only disposed inside one of the longer first annular walls; in some other embodiments, the circular housing extends downward with a circle of first annular walls, and the lamp board is disposed along the circumferential direction inside the first annular wall. The heights of the first annular wall of the housing and the second annular wall of the diffusion plate are substantially the same, and the outer side of the first annular wall is attached to the inner side of the second annular wall.

[0009] To improve the light-emitting effect, the light-emitting assembly includes a reflective paper horizontally disposed above the light guide plate. The light emitted by the lamp beads enters the interior of the light guide plate, and the upper surface of the light guide plate is covered with the reflective paper so that the light in the light guide plate is emitted from the lower surface of the light guide plate, forming a state of planar light emission.

[0010] To avoid forming tooth-shaped light on the diffusion plate near the lamp beads, a gasket is provided between the light guide plate and the diffusion plate. The gasket is disposed along the periphery of the light guide plate, the outer side wall of the gasket contacts the lamp board, and the lamp beads are located above the gasket. There is a certain distance between the lamp beads provided on the lamp board. In the state without the gasket, the lamp beads will directly contact the main board of the diffusion plate, causing the uneven light formed by the spaced lamp beads on the main board and affecting the appearance; in the state with the gasket, the gasket blocks the direct irradiation of the lamp beads on the diffusion plate, so that the lamp beads can only enter the light guide plate from the side wall of the light guide plate first and then be emitted from the lower surface of the light guide plate; the main board area corresponding to the gasket does not emit light.

[0011] To increase the stability of various components inside the housing, an elastic buffer pad is provided between the top shell and the light-emitting assembly. In the state where the side-emitting panel lamp is assembled, the elastic buffer pad is squeezed by the light-emitting assembly and the top shell in the vertical direction. The elastic buffer pad makes the components inside the housing and adjacent components closely fit in the vertical direction; the elastic buffer pad in this embodiment can be selected from rubber materials, EVA foam, etc.

[0012] Preferably, the top shell is recessed downward to form a concave portion, and the inner top wall of the concave portion abuts against the elastic buffer pad. Various components can be concealedly installed on the concave portion, making the appearance of the side-emitting panel lamp simple.

[0013] For the convenience of installation, it further includes a mounting member for mounting the side-emitting panel lamp. A connection hole is provided on the concave portion, and the mounting member is connected to the connection hole.

[0014] To make the arrangement of the components inside the lamp housing more compact, a power supply component is provided between the concave portion and the light-emitting component, and a receiving groove for receiving the power supply component is provided on the elastic buffer pad. The power supply component is arranged in the receiving groove, which saves space and at the same time the elastic buffer pad protects the power supply component.

[0015] To prevent the power supply component from moving in the horizontal direction, a limiting groove is formed on the lower surface of the concave portion, and a part of the power supply component is located in the limiting groove.

[0016] Preferably, a wire passing hole is provided on the top of the housing, and a signal wire connected to the outside is provided in the wire passing hole.

[0017] Compared with the prior art, the advantages of the present utility model are as follows: the peripheral edge of the main board of the diffusion plate is bent to form a lapping portion that laps on the upper surface of the housing, and the housing and the light-emitting component are limited between the lapping portion and the main board. The housing and the diffusion plate encapsulate the components inside the housing to realize the connection and fixation of the overall structure of the side-emitting panel lamp. The whole assembly process is simple, without the need for a screw structure, and the production efficiency is high; moreover, the frame structure is omitted, reducing the weight of the lamp body; in addition, an elastic buffer pad that is compressed is also provided inside the housing, greatly improving the stability of the components inside the housing.
