[0044] The beneficial effects of this application are:

[0045] 1. The periphery of the light box body is sealed by the second side panel and the transparent panel. The second side panel and the transparent panel are sealed and connected, which can effectively prevent rainwater from entering the light box body. The first side panel enhances the waterproof function of the light box body, further reducing the probability of rainwater entering the interior of the light box body, so as to prevent the components inside the light box body from being damaged by rainwater.

[0046] 2. When the light box body is blown down by strong wind, the protective block can reduce the probability of damage to the light box body. The compression spring can reduce the impact force through telescopic movement, and the arc-shaped buffer plate can further reduce the impact force. The support frame can strengthen the connection between the light box body and the base to prevent the light box body from being blown off the base by the wind. The base can be plugged with a counterweight. When the outdoor weather is bad, the staff can add a counterweight to the base to increase the weight of the base and reduce the probability of the light box body being blown down by the wind.

[0047] 3. When the humidity inside the light box body is high, the first blower can blow out hot air, and at the same time the humidity sensor triggers the motor to work. The motor drives the screw rod to rotate back and forth, so that the sliding block moves back and forth in the light box body to evenly heat the inside of the light box body so that water vapor can be quickly discharged from the inside of the light box body. When the temperature inside the light box body is high, the second blower is triggered to work. When the second blower is working, the heat conduction plate cools down, thereby continuously reducing the temperature inside the light box body to avoid damage to the components inside the light box body due to high temperature.
