Claim 6:
7. The optical device of claim 1, further comprising:
another addressable LED group having a plurality of ARGB LED units which are connected in series and controlled serially by another specific sequence of digital signals to display colors;
another input interface circuit, configured to sense a user's another control state;
another control circuit, coupled to the another addressable LED group and the another input interface circuit; and
another specific signal port of the processing circuit, coupled to the another addressable LED group and coupled to the another input interface circuit through the another control circuit, configured to receive the another specific sequence of digital signals and then transmit the another specific sequence of digital signals into an input of another first addressable LED unit in the another addressable LED group in the addressable RGB mode, and configured to receive another output control signal generated from the another input interface circuit by sensing the user's another control state in the input control mode.
