It may be connected to the update control unit 12 of the update control unit 2. Based on the operation signal supplied from the color tone operation unit 31, the update control unit 12 supplies color data for setting the luminance of various neon tubes to each neon module 4 together with the number data. In this configuration, the brightness of each color neon tube of each neon module 4 is easily and reliably adjusted.

- the update control unit 12 may supply only the tone data to each neon module 4 without outputting the number data.
- each neon module 4 needs to update the pattern data when the voltage of the commercial power supply becomes “OV” (zero cross point), for example.
- the color tone operation unit 31 can be configured by a slide volume capable of adjusting the color tone of each color, a control unit (for example, the personal computer 6) that outputs a serial communication signal using DMX-512, and the like.
