Abstract

The invention discloses an LED nixie tube. The LED nixie tube comprises a shell and an LED light-emitting assembly, a cavity for installing the LED light-emitting assembly is arranged in the shell, adisplay panel is arranged at one end of the shell, an opening is formed in the other end of the shell, and hollow parts are arranged on the display panel; the hollow parts form a display pattern, lenses are embedded in the hollow parts, the LED light-emitting assembly comprises a PCB, one side surface of the PCB faces the display panel, a plurality of LED chips are arranged in the corresponding hollow parts, and a plurality of pins are vertically arranged on the surface of the other side of the PCB; positioning columns are arranged on the surface of the inner side of the display panel, and positioning holes which are connected with the positioning columns in an inserted mode are formed in the PCB; the inner side wall of the shell is provided with limiting protrusions which abut against thesurface, facing the display panel, of the PCB and elastic hooks which abut against the surface, back to the display panel, of the PCB; the PCB is fixedly connected with the shell in a glue filling mode, and glue used in the glue filling process is transparent glue. The LED nixie tube has the advantages of being simple in structure, high in 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...
