Alto Electronics obtained a patent for a water intrusion warning LED display box

The patent abstract shows that this application relates to the field of LED display technology, and in particular to a water intrusion warning LED display box. The utility model provides a water intrusion warning LED display box, which includes a frame, an LED display module, and a power box. The LED display module is spliced ​​to one side of the frame, and the power box is arranged on the other side of the frame. The power box includes a HUB board and a front cover. The HUB board is arranged in the power box, and the front cover includes a transparent window. By adding a humidity sensor to the HUB board in the power box, and allowing direct observation through the transparent window on the outer cover, the purpose of humidity early warning is achieved and the risk of maintenance of the LED display box is reduced. The additional transparent window on the outer cover of the power box enables direct observation of water leakage during waterproof testing without opening the outer cover of the power box, reducing the risk of secondary water intrusion in the power box, while improving production and testing efficiency.
