[0001] The utility model relates to the field of LED screens, in particular to a brightness self-adjusting LED display screen with a light intensity sensing function. Background Art

[0002] LED screen is a new type of imaging electronic device made of light-emitting diodes arranged in sequence. Due to its high brightness, wide viewing angle and long life, it is widely used in products such as outdoor advertising screens.

[0003] Existing large LED display screens can be completed by splicing multiple small screens. When the screens are spliced, the gap between the screens is small and there is no protective mechanism. During disassembly and installation, improper force applied by personnel can easily damage the screen.

[0004] Therefore, it is necessary to propose a brightness self-adjusting LED display screen with light intensity sensing function to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a brightness self-adjusting LED display screen with a light intensity sensing function, so as to solve the problem that the existing large LED display screen can be completed by splicing multiple small screens, and when the screens are spliced, the gap between the screens is small and there is no protection mechanism. During disassembly and installation, improper force applied by personnel can easily damage the screen.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a brightness self-adjusting LED display screen with a light intensity sensing function, comprising a first screen body and a second display screen, the first screen body and the second display screen being snap-fitted and connected, and the bottom ends of the first screen body and the second display screen are fixedly connected to a fixed base, one side of the fixed base is telescopically provided with an extended end, the end of the extended end is fixedly connected to a first magnet, the other side of the fixed base is provided with a snap-fitting groove, the top end of the extended end is embedded with a plurality of light sensors, a through groove is provided on the side of the extended end away from the fixed base, and the through groove is connected to the snap-fitting groove.

[0007] Preferably, a protruding groove is provided on one side of the fixed base away from the engaging groove, the protruding end is slidably fitted in the interior of the protruding groove, a spring is fixed between the interior of the protruding groove and the protruding end, and the protruding groove is connected to the through groove.

[0008] Preferably, a second magnet is fixed inside the engaging groove, the protruding end matches the length and width of the engaging groove, and the second magnet is adsorbed and connected to the first magnet.

[0009] Preferably, L-shaped corner guards are fixed to the four corners of the fixed base, and the four L-shaped corner guards are magnetic.

[0010] Preferably, a connection port is provided at the bottom end of the fixed base, and a connection cable is inserted into the connection port.

[0011] Preferably, one end of the extending end extends out of the extending groove.

[0012] Preferably, the top end of the light sensor is flush with the top end of the protruding end.

[0013] Technical effects and advantages of the utility model:

[0014] 1. In the actual operation of the present invention, the first screen body and the second display screen can be installed in parallel and docked. When a large screen is formed, the protruding end of the second display screen can be snapped into the snap-in groove of the first screen body. At this time, the first magnet and the second magnet are adsorbed and connected, so that the first screen body and the second display screen are connected and fixed to avoid movement, which is convenient for personnel to install.

[0015] 2. After the installation of the entire screen is completed, the protruding end of the first screen body at the edge has no other screen docked and installed, and the protruding end will extend out of the corresponding protruding slot. When the protruding end extends out of the outside, the multiple light sensors embedded in the top of the protruding end can detect the external light conditions in real time. At the same time, since the protruding end is in the outside air, the outside air can enter the interior of the fixed base from the through slot, and the air will flow from the through slot to the locking slot in turn to dissipate the inner side of the first screen body. At the same time, since multiple screens are docked in parallel, the air will also be connected to the second display screen to complete the air exchange and dissipate heat for all parallel docked screens at the same time.

[0016] 3. Furthermore, when the large screen needs to be disassembled, the screen can be pulled out through the extended end at the edge, so that a gap is generated in the spliced ​​large screen, which is convenient for disassembly of other screens. Since the extended end is provided, personnel can disassemble the screen through the extended end to avoid pressing the screen with their fingers during disassembly, causing pressure damage to the screen. At the same time, when a gap is generated, the second display screen loses the obstruction of the first display screen, and the extended end of the second display screen will automatically pop out by the spring, which is convenient for personnel to extract.

[0017] 3. The four L-shaped corner guards can protect the four corners of the first display screen. When multiple first display screens and second display screens are assembled together, the L-shaped corner guards close to each other can be adsorbed and connected to each other, thereby increasing the connection strength and improving the convenience of installation.
