[0019] Preferred embodiment.

[0020] This embodiment provides a flat lamp panel with a variable surface pattern, including a light guide plate 110, a diffusion plate 120, a protective film 130, and a plurality of pattern layers 140. The light guide plate 110 is disposed above the diffusion plate 120, the protective film 130 is disposed below the diffusion plate 120, the pattern layer 140 is disposed between the diffusion plate 120 and the protective film 130. The pattern layer 140 includes a film body 141, and covering layers 144 are provided at both ends of the film body 141. An adhesion layer 142 is provided between the covering layer 144 and the film body, and photochromic powder particles 143 are provided in the adhesion layer 142. The photochromic powder particles 143 corresponding to each pattern layer 140 are colored under the action of light with different wavelengths. Among them, the photochromic powder particles 143 adopt photochromic material particles in the prior art.

[0021] The light guide plate 110 can evenly distribute point light sources or line light sources, and after diffusion through the diffusion plate 120, the light source passes through the pattern layer 140. By changing the wavelength of the light source, one of the color-changing powder particles 143 is made to show color, thereby forming a relatively obvious and visible pattern. That is, by changing the wavelength of the light source, different patterns can be observed. Also, the pattern layer 140 can be protected by the protection.

[0022] Further, the flat lamp panel with a changeable surface pattern includes a protective ring assembly. The protective ring assembly includes a first protective frame, a second protective frame 220, a third protective frame 230, and a fourth protective frame 240. The first protective frame, the second protective frame 220, the third protective frame 230, and the fourth protective frame 240 are sequentially connected end to end to form a frame body. A first card slot 210 is provided inside the frame body. The light guide plate 110, the diffusion plate 120, the protective film 130, and several pattern layers 140 are all arranged in the first card slot 210. The protective ring assembly fixes the light guide plate 110, the diffusion plate 120, the protective film 130, and the pattern layer 140 inside through the first card slot 210 to ensure the overall stability.

[0023] Further, both ends of the first protective frame and the third protective frame 230 are provided with first connecting parts, and both ends of the second protective frame 220 and the fourth protective frame 240 are provided with second connecting parts. The first connecting parts and the second connecting parts correspond to each other one by one. The first connecting parts and the second connecting parts are connected one by one to form the frame body and fix the light guide plate 110, the diffusion plate 120, the protective film 130, and the pattern layer 140.

[0024] Further, a first mounting block 231 is provided in the middle of the first connecting part. A first mounting cavity is provided inside the first mounting block 231. A first support column 235 and a first limiting column 233 are provided inside the first mounting cavity. The first support column 235 is fixedly arranged at the bottom of the first mounting cavity. A first limiting hole 232 is provided at the upper end of the first mounting block 231. The first limiting hole 232 matches the first limiting column 233. A first telescopic groove 234 is provided at the lower end of the first limiting column 233. The first telescopic groove 234 matches the first support column 235. A first limiting plate 221 is provided on the second connecting part. A first positioning hole 222 is provided on the first limiting plate 221. The first positioning hole 222 matches the first limiting column 233. A first baffle 237 is provided at the lower end of the first limiting column 233. A first spring 236 is sleeved on the first support column 235. The first spring 236 corresponds to the space between the first baffle 237 and the first mounting block 231.

[0025] When the first connecting portion is pushed towards the second connecting portion, the first limiting post 233 is first resisted by the limiting plate, so that the first spring 236 is compressed until the first limiting post 233 aligns with the first positioning hole 222. Then, the first limiting post 233 is pushed into the first positioning hole 222 by the first spring 236, thereby fixing the first connecting portion and the second connecting portion, which is convenient and reliable for connection.

[0026] Further, a first rubber pad 250 is provided in the first card slot 210. The first rubber pad 250 can play a certain buffering role to avoid direct hard contact, play a protective role, and also ensure the reliability of the connection.
