[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a movable lighting device capable of rotating or moving a lighting fixture by a radio signal transmitted from a remote controller.

[0002]

[Prior art]

 The conventional movable lighting device 10 of this type rotates or moves a wireless signal receiving unit 6 for receiving a wireless signal such as infrared rays transmitted from a remote controller 9 and a lighting device (not shown) as shown in FIG. A motor 8 for driving the motor 8, a motor driving circuit 7 for driving the motor 8, and a controller 11 for fetching a wireless signal received by the wireless signal receiver 6 and controlling the motor driving circuit 7 to drive the motor 8 at a constant speed. The control unit 11 is composed of a micro computer 12.

Here, the operation of the control unit 11 including the microcomputer 12 will be described with reference to the flow chart of FIG. First, the microcomputer 12 performs initial settings such as stack setting and input / output port initialization (steps A to D). Next, wait for a certain period of time until the wireless signal is sent from the remote controller 9 (step E). When the wireless signal is sent, the wireless signal is decoded and any key on the remote controller 9 is pressed. It is determined whether is pressed (step F). Then, the motor drive circuit 7 is controlled to drive the motor 8 in the normal direction or in the reverse direction according to the pressed key (step G). In addition, a timer (not shown) for stopping the motor 8 driven by a radio signal from the remote controller 9 after a certain time is subtracted (step H), and the motor 8 is driven when the subtraction timer finishes the subtraction. (Step I) and waits for an interrupt until a wireless signal is sent again from the remote controller 9 (Step E).

In the movable lighting device 10 as described above, when actually moving the luminaire, a wireless signal (pulse train signal) transmitted from the remote controller 9 is pressed by pressing an operation key (not shown) of the remote controller 9. The wireless signal receiving unit 6 receives and moves the lighting fixture according to the flowchart of FIG. First, when continuously operating the lighting equipment, by pressing the operation key of the remote controller 9, wireless signals are continuously transmitted from the remote controller 9 as shown in FIG. 6, and the transmitted wireless signals are received by the wireless signal. The control signal is continuously output from the microcomputer 12 to the motor drive circuit 7 based on the signal received by the unit 6. Further, based on the control signal, the motor drive circuit 7 drives the motor 8 at a constant speed S.

On the other hand, when the lighting fixture is to be slightly operated, the operation key of the remote controller 9 is pushed by one shot. Then, as shown in FIG. 7, two or three pulse train signals are transmitted, and based on this, the microcomputer 12 sends a control signal to the motor drive circuit 7 for the time corresponding to the above two or three pulse train signals. Is output. Based on the control signal, the motor drive circuit 7 operates the motor at a constant speed S.

[0006]

[Problems to be solved by the device]

 However, in the conventional example as described above, even if the operation key of the remote controller 9 is pressed with a single shot in order to make a minute movement of the luminaire, 2-3 pulse train signals are transmitted in one batch, and 2 to 3 pulse train signals are transmitted. A control signal is output from the microcomputer 12 to the motor drive circuit 7 for the time corresponding to the pulse train signal. Since the motor drive circuit 7 drives the motor 8 at a constant speed S for the time corresponding to the pulse train signal of 2 to 3 trains, the lighting device is (constant speed S) × (2 to 3 trains of pulse trains). There is a problem that it is difficult to finely adjust the lighting fixture by making a minute movement because it moves a distance of (signal time). To solve this problem, the constant speed S may be slowed down, but on the contrary, there is a problem that the operability is deteriorated because the speed of the normal continuous operation is also slowed down.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a movable lighting device that can be easily fine-tuned by a fine movement without deteriorating the operability of continuous movement. is there.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a lighting fixture, a motor for rotating or moving the lighting fixture, a driving means for driving the motor, and a receiving means for receiving a radio signal transmitted from a remote controller. And a controller for controlling the driving means and adjusting the driving speed of the motor according to the received radio signal, the controller receiving the radio signal received by the reception means. The time interval is measured, the preset reference time and the reception time interval are compared, and if the reference time is longer than the reception time interval, the drive means is controlled to drive the motor at the preset initial speed. When the reference time is shorter than the reception time interval, the drive means is controlled to drive the motor by gradually increasing the speed from the initial speed to a preset constant speed higher than the initial speed. Of.

[0009]

[Action]

 In the configuration of the present invention, the lighting equipment, the motor for rotating or moving the lighting equipment, the driving means for driving the motor, the receiving means for receiving the radio signal transmitted from the remote controller, and the wireless means received by the receiving means. The control unit controls the driving unit and controls the driving speed of the motor according to the received radio signal, and the control unit measures the reception time interval at which the reception unit receives the radio signal and The set reference time is compared with the reception time interval.If the reference time is longer than the reception time interval, the drive means is controlled to drive the motor at the preset initial speed, and the reference time is received. If the time is shorter than the time interval, the drive means is controlled to gradually increase the speed from the initial speed to a preset constant speed that is higher than the initial speed to drive the motor, so that the lighting fixture is operated in small increments. Therefore, when a radio signal of 2 to 3 pulse train signals is transmitted from the remote controller, the reference time becomes longer than the reception time interval, and the driving means drives the motor at an initial speed slower than a constant speed to Fine adjustment made possible by minute movements. Furthermore, when a continuous wireless signal of a pulse train signal is transmitted from the remote controller to operate the lighting fixture continuously, the reference time becomes shorter than the reception time interval, and the driving step is gradually slower than a certain speed from the initial speed to the stepwise speed. It is possible to increase the speed and drive the motor to give an acceleration to the continuous operation speed of the lighting equipment.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic block diagram of this embodiment. The movable lighting device 1 of the present embodiment includes a wireless signal receiving unit 6 that receives a wireless signal such as infrared rays transmitted from a remote controller 9, a motor 8 that rotates or moves an illumination device (not shown), Control that includes a motor drive circuit 7 that drives the motor 8 and a microcomputer 3 that takes in the wireless signal received by the wireless signal receiving unit 6 and controls the motor drive circuit 7 through the speed adjusting unit 5 and the speed adjusting unit 5. The microcomputer 3 includes a timer 4 for measuring a reception time interval t at which the wireless signal reception unit 6 receives a wireless signal transmitted from the remote controller 9. Further, the microcomputer 3 is preset with an initial speed S0 when the motor 8 is driven from a stopped state and a reference time T0 for comparison with the reception time interval t.

Next, the operation of the movable lighting device 1 in this embodiment will be described with reference to the flowchart in FIG. The initial settings (steps 1 to 4) are the same as those in the conventional example, and will not be described. When the initial setting is completed, wait for a fixed time until the wireless signal is sent from the remote controller 9 (step 5). When the wireless signal is sent, the wireless signal is decoded and processed by the remote controller 9. It is determined which key is pressed (step 6). At the same time, the reception time interval t at which the radio signal transmitted from the remote controller 9 is received by the radio signal receiving unit 6 is measured by the timer 4 (step 7), and the reference time T0 preset in the microcomputer 3 is set. After comparison (step 8), the speed adjusting unit 5 is controlled according to the result to set the drive speed of the motor 8 (steps 9 and 10). Then, the motor drive circuit 7 is controlled through the speed adjusting unit 5 to drive the motor 8 at the set drive speed. Further, a subtraction timer (not shown) for stopping the motor 8 driven by a radio signal from the remote controller 9 after a predetermined time is subtracted (step 12), and the motor 8 is driven when the subtraction timer finishes the subtraction. It stops (step 13) and waits for an interrupt until a wireless signal is sent again from the remote controller 9 (step 5).

As described in the conventional example, even when the operation key of the remote controller 9 is pressed with a single shot, two to three consecutive pulse train signals are transmitted as a radio signal in a lump. Therefore, the reception time interval t in the first two to three consecutive pulse train signals is not compared with the reference time T0, and the drive speed is always set to the initial speed S0 to drive the motor 8. Then, the reception time interval t is compared with the reference time T0, and if the reception time interval t is larger than the reference time T0 (t> T0) as shown in FIG. The speed adjusting unit 5 is controlled to set the drive speed to the preset initial speed S0 (step 10), and the motor driving circuit 7 is controlled through the speed adjusting unit 5 to finely drive the motor 8 at the initial speed S0. be able to.

When the operation key of the remote controller 9 is continuously pressed to continuously operate the lighting equipment, the reception time interval t is smaller than the reference time T0 as shown in FIG. 3 (t <T0). Will be continuous. Also in this case, the reception time interval t in the first two to three consecutive pulse train signals is not compared with the reference time T0, and the drive speed is set to the initial speed S0 to drive the motor 8, but the radio signal continues to be received. Since it is received, it is judged to be continuous motion, and the speed is gradually increased from the initial speed S0 to a preset constant speed S of continuous motion. That is, the driving speed of the motor 8 can be given an acceleration.
