Description

Technical Field

[0001] The utility model belongs to the technical field of billboards, and in particular relates to an LED billboard. Background Art

[0002] LED advertising is a new media advertising form, which is a perfect combination of new media technology and outdoor advertising. LED advertising is the use of light-emitting diodes to make up advertising words or pictures. For example, we usually see large electronic screen advertisements on the street or some bright advertising words and signs with colorful lights on the roadside. LED is a semiconductor that can convert electrical energy into visible light. It changes the principle of tungsten filament light emission of incandescent lamps and three-primary color powder light emission of energy-saving lamps, and uses electric field light emission. LED display screen is a display screen that displays text and images by controlling the display mode of semiconductor light-emitting diodes. LED display screens mainly include graphic display screens and full-color display screens.

[0003] For example, a Chinese patent with announcement number CN208706183U discloses an LED billboard that solves the use problem of LED billboards, including an LED box and a frame body. The LED box is provided with a cavity chamber, and the cavity chamber has an opening. The LED box is provided with a plurality of LED modules and a connecting frame for installing the LED modules at one end of the opening. The LED module has a mounting surface on the side of the cavity chamber, and the mounting surface is provided with a thermal insulation belt along the edge, and a plurality of semiconductor power generation chips are provided in the center of the mounting surface. A fan, a battery and a control module are provided in the cavity chamber, which is energy-saving and environmentally friendly, increases the service life, and reduces the influence of problems such as LED screen light attenuation. Semiconductor power generation chips and heat dissipation structures are utilized to enhance the power generation effect while reducing the operating temperature of the LED box, and are practical and economical.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the LED of the above device is easy to get wet during long-term use, causing damage to the LED module, and the above device generally needs to be used at a high place. When the LED module is damaged and needs to be repaired, the maintenance personnel need to turn over the above device for maintenance. The above device is too large and may be injured by the maintenance personnel during the manual flipping process, which is very dangerous during maintenance. In view of this, we propose an LED billboard. Utility Model Content
