By pressing the play key, it is possible to shift to a mode in which the elevator lamp body is reproduced from the current position to the stored position, and the elevator lamp body can be moved up and down to the stored position.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a movable lighting device having a lifting function.

[0002]

[Prior art]

 FIG. 8 shows the overall structure of a movable lighting device of this type. A luminaire main body 2 is disposed on the lower surface of the ceiling, and an elevating lamp main body 3 is provided so as to be movable up and down from the lower surface of the luminaire main body 2. That is, a wire 5 is stretched around a winding drum 4 which is interlocked with a motor in the luminaire main body 2, and the elevator lamp main body 3 can be moved up and down by the wire 5 via a pulley 6.

A lamp 7 is provided in the elevator lamp body 3, and the elevator lamp body 3 can be moved up and down by a remote controller 8. A receiver 9 for receiving a signal from the remote controller 8 is installed on the lower surface of the lighting fixture body 2. Incidentally, 10 is a power cord. By driving the motor, winding the wire 5 by the winding drum 4, and rewinding, the elevator lamp main body 3 can be moved up and down to an arbitrary position and stopped at a desired position. The holding for stopping is realized by the gear and the electromagnetic break built into the motor.

All the above operations are performed by the remote controller 8. A perspective view of the remote controller 8 is shown in FIG. On the panel of the remote controller 8, there are provided an on-key 11 for turning on the lamp 7, an off-key 12 for turning off the lamp, an up key 13 for raising and lowering the elevator lamp body 3, a down key 15 for lowering, a stop key 14 for stopping the elevator. is there.

Further, as will be described later, the remote controller 8 is provided with a memory key 16 for storing the position of the elevator lamp body 3 and a reproduction key 17 for moving up and down (moving) the elevator lamp body 3 to the stored position. There is. If the up key 13 or the down key 15 of the remote controller 8 is pressed, the motor is rotated in that direction, and if the stop key 14 is pressed, the motor is stopped.

FIG. 9 is a block diagram of a control device provided in the luminaire main body 2. The CPU 21 of the control unit, the driver 22 for driving the motor 23, the remote control signal receiving unit 24 in the receiver 9, It is composed of an upper and lower limit sensor 25 for detecting the upper and lower limits of the elevator lamp body 3, a storage unit 26 for storing the position of the elevator lamp body 3, and an elevator length sensor 27 for measuring the elevator length of the elevator lamp body 3. ing.

For the sake of safety, the device is provided with the above-mentioned upper and lower limit sensors 25 capable of detecting the uppermost point (a state in which the elevator lamp body 3 is housed) and the lowermost point (a state in which all the wires 5 are fully extended). ing. Usually, these upper and lower limit sensors 25 are constituted by limit switches, and are input as signals to the CPU 21 (some of which cut off the circuit by a switch).

At the center of the control unit is a CPU 21, which interprets a remote control signal and performs processing of rotating the motor 23 up, down, or stopping accordingly. Although the conventional single function of only raising and lowering is as described above, as one of the higher functions, a device that stores and raises (raises and lowers to that position) the storage position of the raising and lowering position in the storage unit 26 including an EEPROM is conceivable. It's starting to happen.

These operations are shown in the flowcharts of FIGS. 11 and 12. FIG. 11 shows a flowchart of interrupt processing, and FIG. 12 shows a flowchart of main processing. The remote control signal is judged by interruption. That is, as shown in FIG. 11, the remote controller signal is input checked and the pulse width is checked at regular intervals. Since the pulse consists of a leader pulse, a trailer pulse, and a data bit pulse of 0 and 1, these are discriminated and processed respectively.

When a reader (initial) pulse arrives, initialization processing is performed to clear data such as flags. When 0 and 1, these bit data are stored in order. When the trailer (end) pulse arrives, the stored bit data is judged to be correct (for example, the parity bit is checked, there is a leader pulse, etc.), and the processed data (that is, the key The corresponding number) data is created and a remote control data present flag indicating that there is remote control data is set.

In the normal processing, this flag is confirmed, and if there is a flag, the processing is performed according to it. For example, as shown in FIG. 12, when it is determined that the up key 13 or the down key 15 is pressed, the motor 22 is driven through the driver 22 by the rotation method according to the up / down movement. The stop key 14 performs processing for stopping the motor 23. The memory key 16 stores the ascending / descending length read from the ascending / descending length sensor 27, which detects the ascending / descending length performed at the end of the interruption, in the storage unit 26.

The playback key 17 determines whether to move up or down so as to move from the current position to the stored position, and performs a process of rotating the motor 23 in that direction. The other processes are processes such as turning on and off the lighting, which are not the subject here, and thus the description thereof will be omitted. Also, as shown in FIG. 12, when the elevator lamp body 3 is moved up and down, the upper and lower limits are checked by the upper and lower limit sensors 25 so as not to fall outside the lifting range for safety. Stop. If not, the rotation of the motor 23 is continued as it is.

At this time, if the reproduction is being performed, it is determined whether or not the target position has been reached. If the target position has been reached, the motor 23 is stopped, and otherwise the rotation of the motor 23 is continued. By performing the above processing, this device can raise and lower the elevator lamp body 3 to an arbitrary position.

[0014]

[Problems to be solved by the device]

 However, in such a conventional example, although the raising / lowering stop position of the lifting / lowering lamp main body 3 can be arbitrarily set, since it is performed by operating the memory key 16, when the position is to be stored, the memory key 16 is operated one by one. There was a problem that it was very troublesome.

The present invention has been made in view of the above points, and an object of the present invention is to provide a movable lighting device for the purpose of eliminating extra key operation and improving operability.

[0016]

[Means for Solving the Problems]

 The present invention comprises a lighting fixture body installed on the lower surface of the ceiling and a lifting lamp body that is suspended from the lighting fixture body by a wire or the like and is capable of moving up and down. In the movable lighting device equipped with a control unit, the elevator lamp body is moved up and down to stop at an arbitrary position, the position when stopped for a certain time or more is stored, and the elevator lamp body is moved up and down to that position. It is equipped with storage control means.

[0017]

[Action]

 Therefore, when the elevator lamp body is stopped at any position for a certain period of time or more, the position can be stored, and the position can be called to bring the elevator lamp body to that position. Unlike the past, it is possible to eliminate extra key operations and improve operability.

[0018]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of a control unit of this embodiment, and FIG. 2 shows a perspective view of a remote controller 8. As shown in FIG. 1, a timer 28 is provided in addition to the conventional block, and as shown in FIG. 2, the conventional memory key is eliminated.

Further, FIG. 3 shows a flow chart of the operation of this embodiment, and although the outline of the operation flow is almost the same as the conventional one, the following points are different. That is, as shown in FIG. 3, at the same time as stopping the motor 23, the count value of the timer 28 is cleared and the timer 28 is operated, and if the timer 28 is operating at the end of the process, the count value of the timer 28 is If a certain time has passed (for example, several minutes or more), the current position of the elevator lamp body 3 is stored in the storage unit 26, and the counting operation of the timer 28 is stopped.

If the process of operating the motor 23 such as up and down of the elevator lamp body 3 by the up key 13 and the down key 15 is in this period, the timer 28 is stopped. As a block, since only the timer 28 is added, it can be realized with a very simple structure. Then, when the reproduction key 17 is pressed, as shown in the flow chart of FIG. 3, the mode is changed to a mode in which the elevator lamp body 3 is reproduced from the current position to the stored position, and the elevator lamp body 3 is moved up and down to the stored position. be able to. These controls are performed by the CPU 21, and the CPU 21 and the storage unit 26 constitute a storage control means.

By the way, in the above-mentioned embodiment, the case where one position is stored has been described. However, the present invention is not limited to this, and the position data is sequentially stacked using the memory that is the storage unit 26 in the playback mode. By calling, you can save and play multiple position data. For example, the operability can be improved by storing the uppermost point (storage position) of the elevator lamp body 3 and the use position and calling them alternately.

Second Embodiment In the above-described embodiment, the lifting device has a single axis of rotation, but in the present embodiment, the movable lighting device performs a two-axis rotation. That is, FIG. 4 is a perspective view of the movable mechanism portion, and a U-shaped arm 33 is attached to the lower surface side of the fixed plate 31 via a motor 32 for horizontal drive. A lamp 35 is attached to a shaft 34 inside the arm 33. A vertical drive motor 36 is provided on one side of the shaft 34, and a rotation angle sensor 37 including a potentiometer is provided on the other side. Has been. A rotation angle sensor 38 including a potentiometer or the like is provided on the motor 32 side.

In this embodiment, since the rotation is biaxial, the operation panel of the remote controller 8 has a left key 18, a right key, as well as an up key 13, a stop key 14, and a down key 15, as shown in FIG. 19 is provided. Here, the up key 13 and the down key 15 are for vertical axis operation, and the left key 18 and the right key 19 are for horizontal axis operation.

FIG. 5 shows a block diagram of the control unit, in which drivers 22 for driving the motors 32 and 36 for the horizontal axis and the vertical axis are respectively provided, and signals from the rotation angle sensors 38 and 37 are provided. Is input to the CPU 21. The other structure is the same as that of the previous embodiment. This embodiment is basically different from the previous embodiments in that it has one axis and two axes. The difference is that the rotation angle sensors 37 and 38 interlocked with the respective rotation axes are attached. Although omitted here, a limit sensor is provided so as not to rotate more than a certain angle in the vertical direction and the horizontal direction as in the case of lifting and lowering.

Further, as shown in the flow chart of FIG. 7 of the main process, when the up key 13, down key 15, left key 18, and right key 19 are operated, if the timer 28 is operating, the timer 28 is stopped. If it is not operating, the process discrimination is performed according to the type of the operated key, and the motor 32 or 36 is driven to rotate. Further, in the case of horizontal rotation, the left and right limit sensors perform a check to determine whether or not it is within the operation range, and the motor 32 is rotated or stopped. Also in the case of vertical rotation, similarly, the limit sensors for up and down are checked, and it is judged whether or not it is within the operation range, and the motor 36 is rotated or stopped.

Then, when both the horizontal and vertical motors 32 and 36 are stopped, the operation of the timer 28 is started (count is cleared). The timer 28 starts its operation and reads the count value. When a certain time has elapsed, the current angle is stored and the timer 28 is stopped as in the previous embodiment. That is, in this embodiment, the operation flow is basically the same as that of the previous embodiment, but in order to completely stop the motor, it is necessary to stop the two axes together, and accordingly, the operation of the timer 28 also. Both axes are stopped before starting.
