Abstract

The invention discloses an LED digital tube, which comprises a casing and an LED light-emitting assembly. A cavity for installing the LED light-emitting assembly is arranged inside the casing. A display panel is arranged at one end of the casing, and an opening is arranged at the other end. A hollow part is provided, and the hollow part is configured to display a pattern, and a lens is embedded in the hollow part. The LED light-emitting component includes a PCB board. There are several pins vertically arranged on the surface of the other side, the inner surface of the display panel is provided with positioning columns, and the PCB board is provided with positioning holes plugged with the positioning columns, and the PCB board and the housing are fixedly connected by filling glue. The colloid that adopts is transparent colloid. The LED digital tube of the invention has the advantages of simple structure, high production efficiency and the like.

Description

technical field [0001] The invention relates to a digital tube, in particular to an LED digital tube. Background technique [0002] Nixie tubes are very commonly used in electronic display circuits, which can realize system display as an interface between man and machine. LED digital tubes are composed of light-emitting diodes, also known as semiconductor digital tubes. The strip-shaped light-emitting diodes are connected according to the method of common cathode (negative pole) or common anode (positive pole) to form the word "8", and then the other electrode of the light-emitting diode is used as a stroke electrode to form an LED digital tube. If the light-emitting diodes on some strokes are made to display a series of numbers from 0 to 9 as required. Compared with fluorescent digital tubes and glow digital tubes (NRT), it has the advantages of small size, low power consumption, shock resistance, long life, high brightness, good monochromaticity, and short luminous respo...
