First mounting blocks 170 are provided at both ends of the first heat collecting plate 150. The first mounting blocks 170 and the first mounting grooves 180 correspond to each other one by one. The first motor 183 is arranged in one of the first mounting grooves 180. A first screw rod 181 is provided at the lower end of the first motor 183. A first threaded hole 171 is provided on one of the first mounting blocks 170. The first screw rod 181 is matched with the first threaded hole 171. First guide rods 182 are provided in the other three first mounting grooves 180. First guide holes 172 are provided on the other three first mounting blocks 170. The first guide rods 182 and the first guide holes 172 correspond to each other one by one.

[0022] Further, the lighting mechanism includes a first lamp shade 140 and a number of LED lamp strips 141. The LED lamp strips 141 are arranged at the lower end of the first lamp shade 140. The first lamp shade 140 is arranged at the lower end of the first heat collecting plate 150. A number of first heat dissipation fins 151 are provided at the upper end of the first heat collecting plate 150. A first fan 120 is provided at the left end of the first top frame 100. A number of first heat dissipation holes 130 are provided at the right end of the first top frame 100.

[0023] Further, the light protection mechanism includes a first grille plate 230 and a first light protection plate 240. The first light protection plate 240 is arranged at the lower end of the first bottom frame 200. The first grille plate 230 is arranged at the upper end of the first bottom frame 200. A number of first grille holes 231 are evenly provided on the first grille plate 230. The first grille holes 231 are square.

[0024] Further, several second mounting grooves 250 are provided at both ends of the first top frame 100. A first pressing block 260 and a first spring 270 are provided in the second mounting groove 250. One end of the first spring 270 is connected to the bottom of the second mounting groove 250, and the other end of the first spring 270 is connected to the first pressing block 260.

[0025] Further, first limiting grooves 251 are provided at both ends of the second mounting groove 250. First limiting protrusions 261 are provided at both ends of the first pressing block 260, and the first limiting protrusions 261 and the first limiting grooves 251 correspond to each other one by one.

[0026] Working principle: Place the first eye protection plate 240 at the lower end of the first bottom frame 200, place the first grille plate 230 at the upper end of the first eye protection plate 240, and then use the first pressing block 260 to press the first grille plate 230, that is, the first spring 270 is in a stretched state. The pulling force of the first spring 270 pulls the first pressing block 260 downward, so as to press the first grille plate 230 and the first eye protection plate 240 tightly. In the cooperation of the first limiting protrusion 261 and the first limiting groove 251, the movement of the first pressing block 260 can be restricted, and the first pressing block 260 is prevented from moving out of the second mounting groove 250. Fix the first heat collecting plate 150 on the first top frame 100, fix the first lamp shade 140 at the lower end of the first heat collecting plate 150, and then buckle the first top frame 100 on the first bottom frame 200, so that the first connecting ring 110 is buckled in the first opening 210, and the interference connection setting ensures the connection between the first top frame 100 and the first bottom frame 200. At the same time, the first barb 160 is hung on the first hanging hole 220, which can ensure that the first top frame 100 and the first bottom frame 200 will not slide, that is, ensure their stability. The controller in the first top frame 100 controls the LED light bar 141 to light up. The first heat collecting plate 150 absorbs the heat of the LED light bar 141 and the first lamp shade 140, and dissipates the heat through the first heat sink 151. The first fan 120 blows the heat towards the first heat dissipation hole 130 and dissipates the heat outwards. When the LED light bar 141 emits light, the first grille plate 230 can adjust the irradiation angle of the light through the first grille holes 231, avoiding direct irradiation from hurting the eyes. Among them, the first grille plate 230 is made of acrylic sheet, which can ensure the normal light emission of the LED light bar 141 and will not affect the lighting effect of the LED eye protection flat lamp.

[0027] In addition, the first motor 183 drives the first screw 181 to rotate. Through the cooperation between the first screw 181 and the first threaded hole 171, the first heat collecting plate 150 moves up and down along the first guide rod 182, thereby adjusting the distance between the LED light bar 141 and the first grille plate 230. Thus, the angle of the light source can be adjusted, and then the illumination range of the flat lamp can be adjusted, so that the best lighting effect can be brought according to actual use.

[0028] It is worth mentioning that technical features such as the first eye protection plate 240 involved in the patent application of the present utility model should be regarded as the prior art. The specific structures, working principles, and possible control methods and spatial arrangement methods of these technical features can be selected conventionally in the art, and should not be regarded as the innovative points of the patent of the present utility model. The patent of the present utility model will not be further specifically elaborated.

[0029] For those skilled in the art, the technical solutions described in the foregoing embodiments can still be modified, or some of the technical features can be equivalently replaced. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
