JP 2002-109948 A

  In a lighting fixture that is moved up and down by remote operation, as described in the above-mentioned document, it is reasonable to provide an infrared remote control receiver on the lower surface of the fixture body in that it can receive infrared signals well from any direction.

  However, as a lighting fixture manufacturer that must prepare various types of lighting fixtures according to user's hobbies and preferences, it is efficient for product management to provide infrared remote control receivers in each type of fixture body. Not right. In view of this, it is conceivable to provide a receiving unit for controlling turning on / off of the appliance main body and driving of the lifting device on the upper mounting body side fixed to the ceiling. According to this, since it is not necessary to provide a receiving part in an instrument main body, the cost increase of an instrument main body can be avoided and the product management efficiency as a lighting fixture manufacturer also becomes favorable. In addition, for the user, there is a merit that the instrument body to be suspended can be freely selected from various types, and the replacement can be easily performed.

  However, when the receiving part of the infrared remote controller is provided on the upper mounting body in the lifting type lighting fixture, depending on the installation position of the receiving part, when the instrument body is raised, the receiving part is hidden and the infrared signal from below is good. Inconvenience that it becomes impossible to receive. In particular, the upper mounting body fixed to the ceiling surface is desired to be smaller than the instrument body so as to be as inconspicuous as possible for design reasons, so that the conditions for receiving infrared signals become more severe.

  The present invention has been made in view of the circumstances as described above, and can be remotely controlled even when the instrument body is raised without lowering the product management efficiency of the instrument body in the hanging lift lighting fixture. It provides a means of improvement.

  In order to achieve the above-described object, the suspended lifting type lighting apparatus of the present invention is suspended from a suspension base installed on a ceiling surface, and can be lifted and lowered from the suspension base, and is electrically connected to the suspension base. A suspended elevating lighting apparatus formed such that a horizontal projection area of the instrument body is larger than a horizontal projection area of the suspension base, and a microphone and a voice recognition unit on the suspension base. The voice control means is provided, and the voice control means recognizes a command voice for turning on / off and raising / lowering operation by a human voice and controls turning on / off and raising / lowering operation of the instrument body.

  Since the suspended lifting lighting fixture of the present invention configured as described above uses sound as a control signal for remote operation, even when the suspended fixture body rises and approaches the ceiling, Stable reception sensitivity is obtained compared to infrared remote control. The voice recognition means consisting of a microphone, voice recognition unit, etc. can be incorporated into the suspension base as a unit or the like, so that compared to the case where the remote control device is incorporated in the instrument body to be suspended, The structure can be simplified and the cost of the instrument body can be prevented from increasing. In addition, this allows the user to freely select or easily exchange the instrument body to be suspended from various types. Furthermore, since the structure of the instrument body is simple, the weight burden of the lifting device incorporated in the suspension base can be reduced, and the lifting operation of the instrument body can be maintained lightly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a schematic configuration of a hanging lift type lighting apparatus according to an embodiment of the present invention. The suspended lift lighting device 1 includes a suspension base 2 installed on a ceiling surface C, and an instrument body 3 that can be lifted and lowered from the suspension base 2, with the instrument body 3 being the suspension base. It has a horizontal projected area much larger than 2.

  The instrument body 3 is suspended from the suspension base 2 via a wire 4 and is electrically connected to the suspension base 2 via a power line 5. A driving unit 6 having a motor for winding the wire 4 is incorporated in the suspension base 2.

  The lighting and extinguishing of the instrument body 3 and the driving of the drive unit 6 are controlled through a control circuit built in the suspension base 2. FIG. 2 shows a block configuration example of the control circuit. The control circuit is roughly divided into a voice recognition circuit 10 that constitutes a voice control means, a lift circuit 20 that controls the drive unit 6, and a lighting circuit 30 that controls the instrument body 3. The voice recognition circuit 10 includes a microphone 11, a noise canceller 12, an amplifier 13, a voice recognition unit 14, and a voice control circuit unit 15. The microphone 11 is attached with the sound collection surface exposed at an appropriate position on the side surface of the suspension base 2. The noise component of the audio signal collected through the microphone 11 is removed by the noise canceller 12 and amplified by the amplifier 13. The voice recognition unit 14 compares the voice signal amplified by the amplifier 13 with the voice pattern of the operation command stored in advance, and identifies the command content. A known conventional voice recognition technique is sufficient as the identification technique.

  A control signal based on the identified command content is sent from the voice control circuit unit 15 to the lift circuit 20 or the lighting circuit 30. The lifting / lowering circuit 20 includes a power supply circuit unit 21 connected to a power supply, a drive control circuit unit 22 that processes a control signal from the audio control circuit unit 15, a drive circuit unit 23 that drives a motor of the drive unit 6, and the like. The lighting circuit 30 includes a power circuit 31 connected to a power source, an oscillation control circuit 32 that processes a control signal from the audio control circuit 15, an oscillation circuit 33 that turns on and off the lamp of the instrument body 3, and the like. And controlling the drive unit 6 or the instrument body 3 based on control signals from the audio control circuit unit 15.

  In this way, by controlling the drive unit 6 and the instrument main body 3 by the control means based on the audio signal, even when the suspended instrument main body 3 rises and approaches the ceiling surface C, it is better than the infrared remote controller. Receive sensitivity can be obtained. The voice control means employed in the hanging lift type lighting apparatus 1 of the present invention is configured to operate only by the user emitting a predetermined command voice toward the suspension base 2, so that remote control transmission is performed to the user's hand. There is no need for a machine, and therefore, it is freed from the trouble of searching for a remote control transmitter each time an operation is performed.

  In addition, the detailed structure and shape of the suspension base 2 and the instrument main body 3 in the hanging lifting type lighting apparatus 1 of the present invention can be freely changed without departing from the gist of the present invention. Moreover, the structure of the raising / lowering circuit 20 and the lighting / light-out circuit 30 controlled by the sound control means is not limited to the above-described form, and can be appropriately changed according to the structure of the appliance.

It is a schematic block diagram of the hanging raising / lowering type lighting fixture which concerns on embodiment of this invention. It is a block block diagram of the control circuit which concerns on embodiment of this invention.
