Description

Technical Field

[0001] The present invention relates to the technical field of LED screens, and in particular to an Internet-based advertising LED screen. Background Art

[0002] LED display is a display device composed of LED lamp beads. It displays various texts, images, videos and other contents by controlling the on and off and brightness of each lamp bead. LED display has the characteristics of high brightness, long life, rich colors and wide viewing angle, and is widely used in many fields.

[0003] For example, the announcement number CN 104269114 B discloses an LED advertising display screen, including a screen body, a mask, a light-transmitting cover, an LED light source assembly, and a heat sink. The mask is made of transparent glass or transparent resin, one side of the mask is movably connected to the screen body, and the other side of the mask is connected to the lamp housing through a buckle tongue lock or a lock. The light-transmitting cover and the lamp housing form a light source chamber, and an LED light source assembly is arranged in the light source chamber. The LED light source assembly includes a substrate and a plurality of LED light sources fixed on the substrate. The substrate is fixed on one side of the heat sink, and a heat dissipation burr is welded on the other side of the heat sink. The heat dissipation burr is conical, and the cross-sectional diameter of the heat dissipation burr gradually decreases from the welding end to the other end. The heat dissipation plate and the lamp housing form a heat dissipation chamber, and the heat dissipation burr is arranged in the heat dissipation chamber. By setting the heat dissipation burr to be conical, the heat dissipation area is increased, the ventilation performance of the heat dissipation plate is improved, and the heat dissipation effect is improved, thereby effectively improving the service life of the display screen, and the cost is low. However, when the above-mentioned LED screen is dissipating heat, its heat dissipation effect is single, and heat is dissipated only by air cooling and increasing the heat dissipation area, so that the heat on the heat dissipation burrs cannot be conducted out in time, thus affecting the use of the LED screen.

[0021] The heat conducting component 65 comprises: The nozzle 651 is connected to the top of the inner side of the rectangular frame; The turbine 652 is installed at the bottom of the nozzle 651 and contacts the water at the water outlet of the nozzle 651 and rotates; The flow guide pipe 653 is arranged in the column 1 and extends to the water tank opened above the base 2; A water pump 654 is installed in the water tank, and its output end is connected to the guide pipe 653, and is used to pump water to spray through the nozzle 651; The guide block 66 is connected to the back of the upper LED screen and is used to guide the water left by the upper heat dissipation fins 61; The guide plate 67 is connected to the back of the lower LED screen and is used to guide the water left by the lower heat dissipation fins 61 to the back plate 5 and flow into the water tank.

[0022] Working principle: When the advertising LED screen is in use, the content to be displayed is projected through the LED screen 3, and the heat generated by the LED screen 3 is transferred through the provided heat dissipation fins 61. At the same time, the water in the water tank is pumped out by the water pump 654, and is guided along the guide pipe 653 to the water outlet of the nozzle 651 for spraying. At the same time, the power of the downward spraying is used to hit the turbine 652, and the turbine 652 is driven to rotate, so that the water flow is diffused and falls on the heat dissipation fins 61 below it, so that the heat on the heat dissipation fins 61 can be conducted away, and the heat is gradually exported by falling in sequence, thereby further improving the heat dissipation effect. At the same time, the water is tilted and dropped by the lowest guide plate 67 to hit the back plate 5, and the back plate 5 is a transparent glass back plate, so that in the process of falling, the effect of a water curtain wall is produced, and then when the display is carried out, it further attracts people to stop and watch, thereby improving the attraction effect.

[0026] Working principle: When the LED screen is in use, it is necessary to regularly maintain and inspect the screen. The motor 71 drives the threaded rod 72 to rotate, thereby pushing the movable block 73 to move, thereby driving the mounting frame 9 connected thereto, and driving the entire module to move up and down, so as to achieve the purpose of maintenance. When the mounting frame 9 moves down, the limit plate 64 fixed on the heat conducting component 65 will be separated from the limit groove 63, thereby releasing the restriction on the mounting rod 62, and then the LED screen 3 can be removed from the mounting frame 9, so that it can be easily inspected on the one hand, and the LED screen 3 can be locked after rising on the other hand.

[0030] Working principle: When the installation frame 9 moves downward, the U-shaped rod 81 and the wiping block 82 connected to the column 1 will pass through the screen, so that the dust on the screen can be wiped off to improve the auxiliary effect during maintenance.
