Abstract: The present invention relates to a circuit for integrating a local switch and a remote-control switch, primarily comprising a remote-control circuit, a first trigger circuit, a second trigger circuit, an integrating unit and a power circuit, in which the integrating unit further comprises two timer circuits, a local switch detecting circuit, a switching circuit and a power supplement circuit. When the circuit described above is in an initial state, in the event of the local switch does not operate within a certain time period, the control priority belongs to the remote-control circuit. When a user controls a load by remote control, the remote-control circuit will send a signal to reset the local switch detecting circuit and to make the output signal of the remote-control circuit be the control source of the switching circuit directly.

Abstract: A circuit arrangement for lamps with melody output includes a switch having a common end connected to an AC voltage source and three contact ends, two rectifiers each respectively connected to a contact end of the switch via a connector, a melody circuit for outputting an audio signal via a speaker, two timers each respectively connected between one of the rectifiers and the melody circuit for controlling the duration of the output audio signal, a lamp driving circuit connected to the melody circuit for receiving a lamp driving signal from the melody circuit, a lamp set connected to all of the contact ends of the switch, and a voltage regulation circuit connected to the AC voltage source via the connector for supplying a power signal to all of the electronic circuits.

Abstract: A music box module is attached to a ceiling fan having a control box mounted on an underside thereof and at least one hole defined in a periphery of the control box. The music box module includes a music box mounted in the control box and having at least one slot defined in a periphery thereof and aligning with the hole. A supporting base is mounted on an underside of the music box and has at least one flange extending upwardly from a periphery thereof to be received in an inner wall of the music box. A bore is defined by a threaded portion of the flange and aligns with the slot. A positioning member extends through the hole, the slot and is securely engaged in the bore.

Abstract: A remote control receiver box assembly includes a body and a casing wherein the body is enclosed by the casing, the body having three concave portions defined in an outer periphery of the body and each of the concave portions being made of transparent material such that a signal receiving element is disposed in the body and is located behind each of the concave portions, the casing having three openings defined in a periphery thereof and when the body is inserted in the casing, each of the concave portions is in alignment with the opening corresponding thereto.

Abstract: A device for engaging a remote control unit to a ceiling fan which has a motor for mechanically actuating blades connected thereto and a rod with a head which extends upwardly from the motor, a fixing element fixedly engaged to the floor and having a C-shaped portion for engagement with the head of the rod, a middle plate having a central hole for the rod to extend therethrough and having at least two sockets extending from an underside thereof, the middle plate received in a bowl which has a hole for the rod to extend therethrough and at least two studs extending from a bottom thereof for engagement with the sockets, electrical elements for remote controlling the ceiling fan disposed in the bowl which is engaged to the fixing element by bolts such that the remote control unit can be repaired simply by disengaging the bowl from the fixing element.

Abstract: An omni-directional infrared sensing circuit includes a plurality of infrared sensors positioned in an different-angled space for receiving external remote control signal, a decoder for checking whether the remote control signal is effective, if positive outputting an effective indicating signal, a multiplexer device connected to the sensors for cyclically allowing one of the sensors to transmit remote control signal, a lock device connected to the multiplexer device responding to the effective indicating signal from the decoder and stop the circulation of the multiplexer device.
