1. illuminator comprises:

  • Two or more led circuits, each led circuit has at least two diodes, and this diode is connected to one another with the reverse parallel connection relation, and at least one diode in these diodes is LED;

    At least one electric capacity, this electric capacity links to each other with each reverse parallel connection led circuit and is its part, and this electric capacity only has an end to link to each other with this reverse parallel connection LED;

    The drive unit that links to each other with one or more led circuits, this drive unit provides AC voltage and current to one or more led circuits, this drive unit and this led circuit form a drive circuit, and this drive unit and this led circuit are configured to such, can add or from this drive circuit, delete led circuit to this drive circuit;

    The predetermined desired output scope of (a) can appreciable impact not any single led light;

    And(b) do not need;

    the value of any one discrete component of any one element that (i) changes the components of drive circuit of the preexist after this change, exist;

    Or (ii) add or delete any such discrete component.
