Description

Technical Field

[0001] The invention relates to detection device technology, and in particular to a protective mask and a detection device thereof. Background Art

[0002] As a customized die-cast aluminum box design, the most important features of the LED rental display are lightness, thinness, and quick installation. The box is light and thin, can be quickly installed, removed and transported, and is suitable for large-scale rental and fixed installation applications. Rental displays are widely used in stage rentals, various press conferences, exhibitions, TV Spring Festival Galas, important cultural activities in various provinces and cities, and other places. Rental products have become the mainstream of the market, and installation and removal have become a normalized trend.

[0003] When used, existing protective mask detection devices mainly focus on evaluating the intensity and various luminous properties of LED masks under static conditions, such as the diversity of lighting modes and the accuracy of brightness adjustment. However, for rental LED display screens that frequently change locations, the transportation process becomes a challenge. When the display screen is disassembled and reassembled for transportation, secondary protection measures are often difficult to achieve perfect conditions due to limitations in site conditions and equipment resources. Therefore, during transportation, especially in poor road conditions, stacked LED display screens may cause damage to the LED lamp beads due to collisions and squeezing with each other, thereby affecting the normal operation of the display screen. Unfortunately, the existing protective mask detection device fails to cover simulation tests in dynamic transportation environments, resulting in an inability to provide sufficient key protection for the LED display screen during transportation.
