The power of AC 220V to 240V is input to the AC power input unit and a power input lamp(LED2) flickers so as to display power input state. The voltage of the power is lowered through a transformer(TRANS1) and rectified through a bridge diode(BD1) functioning as a rectifier. Thus-rectified voltage is smoothed by an electrolytic condenser(C1), and converted into DC 5V through a constant voltage IC(7805). Thus-obtained constant voltage is applied to the program control unit, output voltage sensing unit, and output current sensing unit. The voltage drop unit divides the power input from the power input unit into each step through the transformer, and supplies the voltage to the power input terminal of an illumination device by using semiconductor elements(TRIAC1 to TRIAC5).

The IPC switching unit extracts address information of a destination processor included in the IPC message(S42), and retrieves an IPC routing table using address information of the destination processor(S43). The IPC switching unit judges whether address information of the destination processor exists in the IPC routing table(S44). If address information of the destination processor exists in the IPC routing table, the IPC switching unit detects IPC channel information mapped to address information of the destination processor(S45). The IPC switching unit forwards the IPC message to the destination processor through an IPC channel corresponding to IPC channel information(S46).
