Abstract:
1. A controller adaptive for a light emitting diode module, comprising: a high-voltage power terminal and a low-voltage power terminal; a major switch circuit, coupled between the high-voltage and low-voltage power terminals, having a driving terminal for coupling to at least one LED; an upward-connection terminal and a downward-connection terminal; and a management circuit, coupled to control the major switch circuit, and configured to communicate with an upstream controller via the upward-connection terminal and to communicate with a downstream controller via the downward-connection terminal; wherein the upward-connection terminal is coupled to the downward-connection terminal of an upstream controller; the downward-connection terminal is coupled to the upward-connection terminal of a downstream controller; and the management circuit is capable of operating in one of operation conditions.
