Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the screw-free narrow-frame panel lamp in this embodiment includes a chassis 1, a light emitting assembly 2, a diffuser plate 3, a frame 4, and a pressing block 5.

Wherein, chassis 1 is the disk body structure of downward opening and having the installation cavity, specifically sets up the shape of chassis 1 according to the shape design of lamp body, if when panel light design is the lamp body of rectangle, then chassis 1 is whole for the rectangle. When the panel light is designed as a circular lamp body, the chassis 1 is circular as a whole.

The light emitting assembly 2 is installed in the installation cavity, and the light emitting assembly 2 can adopt various structures of the light emitting assembly 2 in the existing panel lamp. Usually, a power supply module is disposed on the top of the chassis 1, and the light emitting module 2 is electrically connected to the power supply module, so as to switch and adjust the brightness of the light emitting module 2.

According to the needs, the installation structure of the light emitting component 2 is specifically provided, and the light emitting component 2 is directly fixed at the bottom of the installation cavity in the embodiment. Light emitting component 2 can include a plurality of luminescence units, and a luminescence unit includes the lamp plate and sets up a plurality of lamp pearls on the lamp plate. The light-emitting unit in this embodiment adopts a bar-shaped lamp panel, and a plurality of lamp beads are arranged along the length direction of the lamp panel. The light emitting units are arranged in parallel and at intervals.

The side wall of the chassis 1 in the embodiment inclines outwards from top to bottom, so that the side wall of the chassis 1 can play a role of a reflecting cup, and irradiated light rays are more uniform.

The diffusion plate 3 covers the opening of the chassis 1, and the diffusion plate 3 can diffuse the light emitted by the light emitting component 2, so that the emitted light is softer and more uniform.

Frame 4 encloses the periphery of establishing at chassis 1, diffuser plate 3, and frame 4 is through being connected with chassis 1, diffuser plate 3, and then realizes the installation of diffuser plate 3 at 1 opening part on chassis.

The edge of the base plate 1 is turned outwards to form a horizontal flange 11, so that the flange 11 can be attached to the edge of the diffuser plate 3.

The frame 4 includes a main body 41 and a support plate 42 extending inward from the lower surface of the main body 41, and the edge of the diffuser plate 3 is adhered between the support plate 42 and the flange 11, that is, the support plate 42 and the flange 11 are used to fix the diffuser plate 3. During assembly, glue can be applied to the upper and lower surfaces of the edge of the diffusion plate 3, so that the diffusion plate can be bonded with the support plate 42 and the flanging 11.

At least two pressing blocks 5 are arranged on the frame 4 along the circumferential direction, and the number of the pressing blocks 5 can be specifically determined according to the size of the lamp. Briquetting 5 connects on main part 41 dismantled and assembled and presses in the top of turn-ups 11, realizes being connected of chassis 1 and frame 4 through briquetting 5 promptly, and briquetting 5 can also push down the turn-ups 11 of chassis 1 from top to backup pad 42 direction simultaneously for closely laminating between turn-ups 11, diffuser plate 3, the backup pad 42 is connected, and then realizes the fixed connection between chassis 1, diffuser plate 3, the frame 4.

In order to facilitate the detachable assembly of the pressing block 5, the main body 41 is provided with a clamping groove 411, and the clamping groove 411 in this embodiment is opened upward, so that the pressing block 5 can be assembled on the frame 4 more conveniently. The pressing piece 5 has a clamping leg 51 which is matched to be clamped into the clamping groove 411 and a pressing plate 52 which presses on the flanging 11. Specifically, a downwardly inclined engaging portion 412 is disposed on a side wall of the engaging slot 411, the engaging portion 412 has certain elasticity, and a locking portion 511 capable of being engaged with the engaging portion 412 is protruded from a lower end of the locking leg 51. During assembly, the clamping pin 51 of the pressing block 5 is aligned to the clamping groove 411, then the pressing block 5 is pressed downwards, so that the clamping pin 51 of the pressing block 5 moves downwards, when the clamping part 511 on the clamping pin 51 moves downwards to the position of the clamping part 412, the clamping part 412 is pushed to deform to allow the clamping part 511 of the clamping pin 51 to continue moving downwards, and when the clamping part 511 of the clamping pin 51 moves downwards to the position below the clamping part 412, the clamping part 412 resets, so that the clamping pin 51 is limited.

In this embodiment, chassis 1, diffuser plate 3, frame 4 all are the rectangle, and briquetting 5 is the L type and connects in the corner of frame 4, so can effectively guarantee the reliability of being connected between chassis 1, diffuser plate 3, the frame 4.

The utility model provides a no screw narrow frame panel light, 11 levels of turn-ups at 1 edge on chassis set up, the backup pad 42 has been set up in frame 4 simultaneously, so turn-ups 11 through chassis 1, backup pad 42 in the frame 4 can press from both sides diffuser plate 3 and establish between the two, and based on all being plane contact, turn-ups 11 has been guaranteed, backup pad 42 in the frame 4 and the area of contact at 3 edges of diffuser plate, the fixed fastness to diffuser plate 3 has been improved, so only can realize the reliable fixed to diffuser plate 3 through narrower frame 4 structure, the width of frame 4 is A in this embodiment, 8mm is less than or equal to A and is less than or equal to 13mm. The width of the frame 4 in the embodiment is A,8mm is less than or equal to A and less than or equal to 13mm, and A =10mm can be optimized. Meanwhile, the chassis 1 and the frame 4 are further effectively connected by the clamping pressing block 5, and the assembly is more convenient and efficient.
