Description

Technical Field

[0001] The utility model belongs to the technical field of display screen fixing, in particular to a fixing frame of an LED line power module. Background Art

[0002] LED display screens are gaining wide attention and developing rapidly due to their high brightness, low power consumption, stable performance and other characteristics. Moreover, these LED display screens are increasingly used in people's daily lives. LED display screens are composed of LED dot matrices and LED printed circuit boards (PCBs). By controlling the display mode of LED lights, one or more LED lights in red, blue, green and other colors are turned on and off to display text, pictures, animations, videos and other contents. When powering the LED display screen, a large current is required, but the existing LED power supply module is usually placed directly near the LED display screen, which may cause the power supply module to collide with people walking during operation, which may affect the normal operation of the power supply module and may even cause damage to the power supply module. In addition, if the power supply module does not have a fixing frame, there may be safety hazards. For example, the power supply module may fall off due to vibration or impact, which may cause harm to people or equipment. Utility Model Content
