As shown in fig. 1, the embodiment of the present invention provides a schematic diagram of an integrated nixie tube, which can be applied to driving control devices such as a frequency converter, and can be combined with a keyboard to perform simple parameter setting and status display. The integrated nixie tube of the embodiment includes a housing 11, a display panel 12, a plurality of light emitting elements and a plurality of external pins 13, wherein the display panel 12 is disposed on a surface of the housing 11 (for example, disposed on a front end surface of the housing 11), the plurality of light emitting elements can emit light when powered on, the plurality of light emitting elements are disposed in the housing 11, and the external pins 13 are electrically connected with the light emitting elements and exposed out of the housing 11 (for example, exposed out of a rear end surface of the housing 11). In practical applications, the housing 11 and the display panel 12 may be of a unitary structure, for example, a transparent or translucent material as a whole, and the display panel 12 is covered with a film at a corresponding position.

The plurality of light emitter assemblies in this embodiment include K first light emitter groups for displaying numbers and L second light emitter groups for displaying status information, where K, L is an integer greater than or equal to 1, that is, each first light emitter group can display an arabic numeral when energized (in practical applications, the first light emitter group can also display a letter), and each second light emitter group can be energized to display a plurality of different statuses when energized. Also, as shown in fig. 2, the display panel 12 includes a number display area 121 and a status display area 122 (for example, the number display area 121 of fig. 2 can display a five-digit number, and the status display area 122 can display statuses of 6 different indexes).

The digital display area 121 and the status display area 122 may be specifically formed by a hollow structure, a semi-transparent structure or a transparent structure on the display panel 12, and the numbers displayed by the first light emitting units and the statuses indicated by the second light emitting units are transmitted through the hollow structure, the semi-transparent structure or the transparent structure. Light emitted from the first light emitter group in the housing 11 is displayed through the number display area 121 of the display panel 12, and light emitted from the second light emitter group is displayed through the status display area 122 of the display panel 12, that is, the position of the first light emitter group is opposite to the position of the number display area 121, and the position of the second light emitter group is opposite to the position of the status display area 122.

The integrated nixie tube integrates the first luminous body group for displaying the number and the second luminous body group for displaying the state information into the same shell 11, and transmits the number displayed by the first luminous body group and the state information displayed by the second luminous body group through different areas of the display panel 12, so that the visual area of the display panel is increased, the integral consistency is improved, the sight line focusing is facilitated, meanwhile, the indicator light area on the operation panel is reduced, and the operation panel is simpler and tidier; on the other hand, the integrated nixie tube reduces the space duty of the indicating lamp and the nixie tube on the operation panel, and the difficulty of design and production is reduced by meeting the trend of miniaturization and integration of the frequency converter.

In an embodiment of the present invention, each first light emitter group includes a plurality of first light emitters, each second light emitter group includes at least one second light emitter, the first light emitter group is formed by a plurality of first light emitters arranged according to a certain rule in space, and the second light emitter group is formed by at least one second light emitter arranged according to a certain rule in space. The first luminous body and the second luminous body are packaged in the shell 11 in an encapsulating mode, and pins of the first luminous body and the second luminous body are electrically connected with external pins and are connected with other circuit boards (driving circuits) through the external pins. Specifically, the first Light emitter and the second Light emitter may be respectively formed of Light Emitting Diodes (LEDs).

In another embodiment of the present invention, the integrated nixie tube includes a printed circuit board packaged in the housing 11, and the external pins 13 include a plurality of first polarity external pins and a plurality of second polarity external pins, and specifically, the number of the first polarity external pins and the number of the second polarity external pins can be specifically determined by the number of the first illuminant group, the number of the second illuminant group, and the data of the illuminants included in the first illuminant group.

The first polarity pins of all the first illuminants of the same first illuminant group are electrically connected through the printed circuit board and led out to form a first polarity external pin, and the second polarity pins of the first illuminants at the same spatial position of different first illuminant groups are electrically connected through the printed circuit board and led out to form a second polarity external pin. That is, the first polarity pins of the plurality of first light emitters in each first light emitter group are shared, and the second polarity pins of the first light emitters arranged at the same spatial position in different first light emitter groups are shared. Through the mode, the number of the external pins can be greatly reduced.

That is, the first polarity pins of the second light emitters in each second light emitter group are shared.

The pin connection relationship between the first light emitter and the second light emitter is described below with reference to fig. 4 as an example. In fig. 4, in the first five rows of light emitters, each row of light emitters constitutes a first light emitter group, and each column of light emitters represents a first light emitter at the same position in a different first light emitter group. In the same first light emitter group, for example, the first light emitter group including 8 light emitters in the first row in fig. 4, the anodes of all the first light emitters are electrically connected and led out as one anode external pin DIG1 (i.e., connected to the same anode external pin DIG 1); the cathodes of the first illuminants in the same position, for example, the first row of the first illuminants in fig. 4, of the different first illuminant groups are electrically connected and led out to form a cathode external pin a. Eight first light emitters in each first light emitter group are connected to nine external pins in the driving circuit.

Similarly, the anode pins of all the second light emitters in the same second light emitter group (for example, including 7 light emitters in the sixth row in fig. 4) are electrically connected and led out as an anode external pin DIG6, and the cathode pins thereof are respectively connected to different external pins A, B, C, D, E, F, G (when the second light emitter group includes seven second light emitters). That is, seven second light emitters (two of the second light emitters with different colors share one status display unit 1211) in the second light emitter group are connected to the eight external pins. By the mode, the number of the external pins can be greatly reduced, and the driving circuit of the integrated nixie tube is simplified.

Of course, in practical applications, the number and arrangement of the first light emitters in the first light emitter group may also be determined according to practical needs and displayed contents.

Each second luminous body group comprises N second luminous bodies, and N is a positive integer less than or equal to eight. So that the number of the second light emitters of the second light emitter group is less than or equal to the number of the first light emitters in one first light emitter group. Therefore, when the driving circuit is connected, each first luminous body group and each second luminous body group can be used as a controlled unit in the whole, namely, each second luminous body group can be regarded as a digital display assembly, and the circuit design and the layout are facilitated.

In an embodiment of the present invention, the status display area 122 of the display panel 12 includes at least one horizontal bar-shaped area, and the horizontal bar-shaped area is located above or below the number display area 121, and accordingly, the second light emitters in the second light emitter group are arranged in at least one row. Alternatively, the status display area 122 includes at least one vertical bar-shaped area, and the vertical bar-shaped area is located at the left or right side of the number display area 121, and accordingly, the second light emitters in the second light emitter group are arranged in at least one column.

In another embodiment of the present invention, the digital display area 121 may be formed by a large window, or may be formed by a plurality of digital display units 1211 distributed at intervals, and each digital display unit 1211 can transmit light emitted by a first light emitting unit; the state display area 122 includes a plurality of state display units 1221, and each of the state display units 1221 can transmit light emitted by M second light emitters, where M is a positive integer less than or equal to 3. When M is equal to 1, a plurality of second light emitters in the second light emitter group can emit light through one status display unit 1221. When M is greater than 1, the colors of the light emitted by the M second light emitters corresponding to each state display unit 1221 are different (for example, as shown in the third state display unit 1211 in fig. 2), and when M is equal to 2, the state display unit 1221 can display two colors), so that different states can be identified by changing the color of the state display area 122. In addition, one status display unit 1221 may be caused to identify different statuses in other manners, such as normally bright, flash, slow flash, and the like.
