Description

Technical Field

[0002] LED digital tubes are display devices composed of light-emitting diodes (LEDs), widely used in the field of digital displays. They display numbers and characters by controlling the on / off state of different LEDs, offering advantages such as high brightness, fast response, and long lifespan. LED digital tubes consist of multiple groups of LEDs, and based on the connection method, they can be divided into two types: common anode and common cathode. In a common anode digital tube, the anodes are connected together, and the cathodes are controlled separately; in a common cathode digital tube, the cathodes are connected together, and the anodes are controlled individually.

[0003] An LED digital tube packaging structure, as disclosed in publication number CN209328418U, includes a PCB connection motherboard. Multiple fixing screw holes are formed on the lower edge of the PCB connection motherboard. Multiple heat dissipation holes are formed on the lower surface of the PCB connection motherboard inside the fixing screw holes. A PCB motherboard cover film is fixedly mounted on the upper surface of the PCB connection motherboard. Multiple chip guide mounting blocks are fixedly mounted on the upper surface of the PCB connection motherboard inside the PCB motherboard cover film. This LED digital tube packaging structure, with its chip guide mounting blocks and heat dissipation holes, can position the LED during packaging, preventing misalignment and resulting in tilting after packaging. It enhances heat dissipation, allowing the LED to operate more stably, demonstrating practicality and promising future applications.

[0004] The aforementioned device is inconvenient to assemble and disassemble during use; therefore, we propose an LED digital tube packaging structure to solve the problems mentioned above. Utility Model Content
