[0031] When implementing this embodiment, the LED light box 1, the top cover 2, and the bottom plate 4 need to be relatively fixed. First, make the side of the top cover 2 with the positioning connection column 8 face down, align the positioning connection column 8 with the positioning hole 23 on the light box partition 9 and press it down. The convex strip 25 on the positioning connection column 8 will be in interference fit with the positioning hole 23. Then, make the side of the bottom plate 4 with the bottom plate connection column 7 face up and install it in the counterbore at the bottom of the light box partition 9. Since the bottom plate connection column 7, the positioning hole 23, and the positioning connection column 8 are on the same axis, at this time, insert the screw from the bottom of the bottom plate connection column 7. The screw will sequentially pass through the connection hole 20, the first transition hole 21, the transition hole of the top cover 2, and the positioning hole 23, and finally be screwed into the threaded hole 24 in the positioning connection column 8. The length of the screw selected is less than the length of the threaded hole 24, so that the head of the screw will be stuck at the top of the connection hole 20 to play a fastening role. Secondly, the hollow setting of the light box partition 9 can effectively reduce the use of materials. Moreover, in this embodiment, by setting multiple light box plates 3, it is possible to compare different material light box plates 3 under the same color temperature, compare the same material light box plates 3 under different color temperatures, and even display the light-emitting effect under the condition that both are different.

[0032] The six LED light boards provided in this embodiment have six different color temperatures. Each power button 10 independently controls one LED light board. Pressing any of the power buttons 10 can emit various color temperatures. At the same time, by cooperating with replacing the light box board 3, the lighting effects of light box boards 3 of different colors and different materials under different color temperatures can be seen, and more intuitive display and comparison can be carried out. The same area of the LED compartments 15 can ensure that the lighting ranges of the LED light boards in each LED compartment 15 are the same, and the final lighting effect will not be affected by uneven lighting caused by different areas. At the same time, multiple groups of light box boards 3 are provided, each group contains multiple light box boards 3, and each group of light box boards 3 is made of different materials. The thicknesses of the multiple light box boards 3 in each group are different. The different thicknesses of the light box boards 3 refer to the different thicknesses at the middle positions of the light box boards 3, and the thicknesses of the parts where the two sides of the light box board 3 cooperate with the sinking chute 27 are the same. When replacing the light box board 3, first, the sliding cover 11 needs to be pushed upward, and then it can be seen that the light box board 3 is mounted on the sinking chutes 27 on both sides. At the same time, the light box board 3 is located between the top cover 2 and the LED light box 1. At this time, the light box board 3 can be slid out back and forth for replacement. The sliding cover 11 can prevent the light box board 3 from falling off during the use of the device.

[0033] The battery 12 is used for power supply. The battery 12 is detachably arranged in the LED light box 1. The charging port 5 is used to charge the battery 12. The power indicator light 6 is used to display the remaining power and give a charging prompt. The wires used for internal circuit connection in the LED light box 1 are arranged through the internally provided wire trough 19. After the battery 12 runs out of power, it can be replaced or charged through the charging port 5.
