1. a ligthing paraphernalia, possesses:

  • Multiple light source, the glow color of each light source is different, and voltage drop value when respectively flowing through the electric current of identical value is different;

    Multiple light source switch, each light source switch and above-mentioned each light source with 1 to 1 relation be connected in series respectively;

    DC power supply circuit, it has pair of output for output dc voltage, is connected with each series circuit of the light source switch comprising above-mentioned each light source and be connected in series respectively with this each light source between above-mentioned pair of output;

    AndControl circuit, it carries out switch control rule to above-mentioned each light source switch,Wherein, above-mentioned control circuit performs first and controls and the second control these two controls, in this first control, carry out Time-sharing control to above-mentioned each light source switch, during the connection being on-state with this each light source switch, the state of non-overlapping copies makes this each light source switch on-off;

    In this second control, control respectively to the target length during the target current value of this each light source circulation and/or the connection of above-mentioned each light source switch during the connection of above-mentioned each light source switch, adjust the ratio amassed in above-mentioned each light source of the target length during above-mentioned target current value and above-mentioned connection.
