[Embodiment of the invention]

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

The luminaire includes a case 10 on which the lamp L is mounted, a music box 21 with a motor M incorporated in the case 10, and a control circuit 30 for supplying power to the lamp L and the motor M (FIGS. 1 and 2). ). The control circuit 30 is incorporated in the case 10 together with the music box 21.

The case 10 is formed by attaching a bottom plate 12 to a box-shaped case main body 11. An annular rib 11a is formed on the upper surface of the case body 11, and a socket 11c for the lamp L is protruded through an opening 11b in the rib 11a. However, the socket 11c is assumed to be fixed to the bottom plate 12. The bottom plate 12 is screwed to a lower portion of the case main body 11, and short legs (not shown) are formed on the lower surface of the bottom plate 12 so as to face down to the corners.

The lamp L on the case 10 is combined with a light-transmitting lamp cover 15. The lamp cover 15 is formed in a hollow conical shape, and is detachably mounted on the upper surface of the case 10 so as to cover the lamp L. The lamp cover 15 is positioned on the case 10 via the rib 11a so that the lamp cover 15 does not come into contact with the lamp L by locating the lower edge around the rib 11a.

The music box 21 is screwed together with the control circuit 30 onto the bottom plate 12, and the music box 21 is combined with a motor M. The motor M is connected to the drum of the music box 21 via a gear mechanism.

The control circuit 30 is formed by connecting a touch sensor circuit 32, a ring counter 33, and a controller 34 in a cascade, and the touch sensor circuit 32 is connected to a touch electrode 32 a protruding above the case body 11. ing. A power cable with a plug PL is connected to the controller 34, and the output of the controller 34 is branched and connected to the lamp L and the motor M of the music box 21. A switch SW is attached to the motor M, and an operation knob SWa of the switch SW projects outside through an opening 11 d on the side surface of the case body 11. Therefore, the switch SW can be operated from outside the case body 11 via the operation knob SWa.

The control circuit 30 operates as follows by connecting the plug PL to a commercial power outlet.

When the user touches the touch electrode 32a, an operation signal S1 is input to the touch sensor circuit 32, and the touch sensor circuit 32 outputs a detection signal S2. That is, the touch sensor circuit 32 forms a touch sensor together with the touch electrode 32a. On the other hand, the ring counter 33 counts the number of times of contact with the touch electrode 32a, that is, the number N of times of operation of the touch sensor, based on the detection signal S2 from the touch sensor circuit 32, and outputs it to the controller. Note that the ring counter 33 sets the maximum value Nm of the number of operations N to an arbitrary natural number of 3 or more, clears it to N = 0 when the number of operations N = Nm, and sets the number of operations N = 1 to be counted next as N = 1. Counting should be repeated in the range of N = 1 to Nm.

The controller 34 changes the setting of the output voltage V based on the number of operations N from the ring counter 33 to supply power to the lamp L and the motor M, turn on the lamp L, and By driving the music box 21, a predetermined melody can be automatically played. It is assumed that the luminous intensity C of the lamp L and the rotation speed of the motor M, that is, the playing speed S of the music box 21 change according to the output voltage V from the controller 34 (FIG. 3). However, the characteristics of the luminous intensity C and the performance speed S in FIG. 3 are merely examples.

When the touch electrode 32a contacts the touch electrode 32a at times t = t1, t2,... (FIG. 4), the number of operations N from the ring counter 33 changes to N = 1, 2,. Since the output voltage V from V changes stepwise as V = V1, V2,..., The lamp L and the music box 21 change the luminous intensity C and the playing speed S in a plurality of steps in accordance with the change of the output voltage V. be able to. However, in FIG. 4, the maximum value Nm of the number of operations N set in the ring counter 33 is illustrated as Nm = 3. The music box 21 can be stopped regardless of the luminosity C of the lamp L by opening the switch SW via the operation knob SWa.

[0026]

[Other embodiments]

 The lamp L and the motor M may be individually controlled via the controllers 34a and 34b, respectively (FIG. 5). The number of operations N from the ring counter 33 is branched and input to the controllers 34a and 34b.

The controllers 34a and 34b are configured to be adapted to the types of the lamp L and the motor M, respectively, and can control the luminosity C of the lamp L and the playing speed S of the music box 21. For example, when the lamp L is an incandescent lamp, the controller 34a may change the DC or AC output voltage, and when the lamp L is a fluorescent lamp, it is preferable to change the frequency together with the AC output voltage. When the motor M is a DC motor, the controller 34b only needs to change the DC output voltage. When the motor M is an AC motor, the controller 34b changes one or both of the AC output voltage and the frequency. I do.

The touch electrode 32 a and the touch sensor circuit 32 shown in FIG. 2 form a touch sensor that supplies an operation signal S 1 to the control circuit 30. This touch sensor includes a mechanical push button switch, Any switch means such as an infrared sensor for detecting the hand of the operator may be used.

Further, the controller 34 in FIG. 2 and the controllers 34 a and 34 b in FIG. 5 continuously change from the variable setting means such as a variable resistor instead of the number of operations N from the ring counter 33. The operation signal S1 may be input. At this time, the control circuit 30 can continuously control the luminosity C of the lamp L and the playing speed S of the music box 21 in conjunction with an external operation signal S1.

It should be noted that the lamp cover 15 may be formed in any shape such as a hat shape, a cylindrical shape, a dome shape, or the like, regardless of the illustration, and may be provided with a suitable stand.
