Abstract: According to one embodiment, a lighting control circuit includes a rectifying device configured to rectify an output of an alternating constant-current power supply device capable of changing an output current value, a power converting section configured to receive an output of the rectifying device and variably output direct-current power, and a solid-state light-emitting element supplied with the output of the power converting section to be lit. A shunting device configured to shunt a part of an output current from the alternating constant-current power supply is provided on an input side of the rectifying device.

Abstract: A control unit 12 executes a waiting operation by monitoring broadcast data received by a radio unit 11 and reception levels of these data at all times. When the received data being received by the radio unit 11 are found to be coincident with registered data read out from a storing unit 13, the control unit 12 causes an operating unit 14 to display a message of a content that a presence position is recognized on the display screen of a display unit 15, or it causes generation of an alarm tone from a loudspeaker 16, thus notifying the presence position recognition to the user. Afterwards, the control unit 12 sets functions of various items, such as call arrival, call arrival tone level, out-of-home dealing function ON/OFF, preset in the storing unit 13.
