Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, a back plate of a lamp comprises a bottom 2, a side wall 3 arranged around the bottom 2, and a placement part 4 connected to one end of the side wall 3 far away from the bottom 2; one side of the placement part 4 far away from the side wall 3 is connected with a limiting part 5, and the limiting part 5 can be turned between a first position and a second position; when in the first position, an included angle alpha is formed between the limiting part 5 and the placing part 4, and the included angle alpha is not more than 90 degrees; in the second position, the limiting part 5 is parallel to the placement part 4, and the limiting part 5 is located in the orthographic projection of the placement part 4.

In this application, we further reduce the cost and reduce the number of parts by reducing the use of face frames. When the worker installs the diffusion plate 100, only the diffusion plate 100 is placed on the placing plate, and then the limiting part 5 is turned over and pressed, so that the diffusion plate 100 is firmly fixed without using a face frame. After being fixed, the diffusion plate 100 remains stable and does not move. Optimally, the angle α is 90 °. This design facilitates placement of the diffuser plate 100 because the retainer 5 securely retains the diffuser plate 100 in the optimal position once placed.

In this application, the bottom 2, the side wall 3, the placement portion 4, and the stopper portion 5 are integrally formed.

Specifically, as shown in fig. 1, the bottom 2 is provided with a plurality of first reinforcing grooves 21 and a plurality of second reinforcing grooves 22, and the first reinforcing grooves 21 and the second reinforcing grooves 22 are perpendicular to each other.

The vertical arrangement of the first reinforcing groove 21 and the second reinforcing groove 22 can effectively increase the structural strength of the lamp back plate. The reinforcement structure can bear external stress better, so that the stability and durability of the lamp backboard are improved. Such vertically aligned stiffening grooves may provide adequate structural support while reducing material usage.

Specifically, as shown in fig. 4, the placement portion 4 is provided with a protrusion 41 protruding with respect to the surface of the placement portion 4, the protrusion 41 being provided along the length direction of the placement portion 4.

By the protrusions 41, when the limiting part 5 is turned over and abutted against the diffusion plate 100, the lower protrusions 41 can also support the diffusion plate 100, thereby effectively fixing the diffusion plate 100 and preventing the diffusion plate 100 from moving

Specifically, as shown in fig. 1, the side wall 3 is provided with a reinforcing portion 31, and the reinforcing portion 31 extends to the bottom 2.

The reinforcement 31 helps to prevent the side wall 3 from bending or twisting during use. This ensures that the luminaire back plate retains its original shape to meet the usage requirements. Extending the reinforcement 31 to the bottom 2 may significantly enhance the structural performance of the luminaire back plate, improve its stability, durability and load bearing capacity,

specifically, as shown in fig. 1 to 5, the placement portion 4 has a square shape, and the stopper portions 5 have four edges respectively connected to the edges of the placement portion 4.

The four limiting portions 5 are respectively connected to the four edges, so that more stable fixation can be provided, and the diffusion plate 100 is not easy to move or shake. This is important for uniformity of the performance and appearance of the luminaire. And a limit part 5 is arranged independently in each direction, so that the limit part 5 can be folded more easily.

Specifically, as shown in fig. 1 and 5, the two ends of the limiting portion 5 are provided with oblique sides 51, and in the second position, the oblique sides 51 on the adjacent limiting portions 5 are parallel to or abut against each other.

This design can make the outer appearance more attractive by allowing the edge bevels 51 to be positioned parallel to or abut against each other after the stopper 5 is turned over and pressed against the diffusion plate 100.

As shown in fig. 2, 3 and 5, a flat panel lamp includes a lamp back plate. In a specific installation, the diffusion plate 100 may be placed on the placement portion 4, and then the external press or the pressing device is contacted, the limiting portion 5 is reversed toward the diffusion plate 100, and the limiting portion 5 is pressed to compress the diffusion plate 100.
