Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device, and more particularly to a lighting device used when entering and leaving a garage or a warehouse.

[0002]

2. Description of the Related Art When entering or leaving a garage or warehouse, a lighting device is turned on to obtain a light source for entering or leaving. In such a conventional first lighting device, a control line is connected to a limit switch portion that detects an open position and a closed position of an opening / closing body such as an openable shutter provided at an entrance / exit, and based on an output of the limit switch. There is a configuration in which the power supply of the lighting device is switched. With this configuration, the illumination can be continuously turned on for a predetermined time in association with the opening or closing of the shutter.

A second method is to connect a shutter control power source line, that is, a shutter drive motor power source line (for example, three-phase AC200V) to a lighting control panel that operates at the voltage, and press the shutter operation switch. In some cases, the polarity of the power supply line is determined according to the above, and the illumination is continuously turned on for a predetermined time in conjunction with opening or closing of the shutter.

[0004]

In the first lighting device, it is necessary to wire the control line between the limit switch portion of the shutter and the lighting device, and therefore a special wiring is necessary for this purpose. Yes Wiring work was required, and the wiring was exposed to the outside and spoiled the appearance.

Next, in the second lighting device, it is necessary to specially provide a lighting control panel, and since the components constituting the lighting control panel need to have a large capacity, the lighting control panel is required. Became large and costly.

Further, since the first and second illumination devices are installed not only in the vicinity of the opening and closing body such as the shutter but also in any place for the convenience of the installer, the illumination device is installed from this shutter. It is necessary to provide a control line up to the step (1), the number of the control lines is increased, a wiring work for wiring is required, and the appearance is inferior.

When the shutter control and the illumination control are interlocked, the interlocked lighting of the illumination with respect to the shutter must guarantee the same performance in any control device. Here, the problem is that the illumination device is also operated by the operation button for opening and closing the shutter, and the illumination must be turned on when the shutter is operating. That is, since the operation button can be pushed in various ways by the operator, for example, when the operator only presses it for an extremely short time, only the shutter detects it and operates, but the illumination side cannot detect it and lights up. Don't let it happen.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an illuminating device having a simple structure capable of lighting the illuminating device with a minimum number of lead-in wires. It is an object of the present invention to provide a lighting device that can be reliably interlocked with a fixture, can guarantee stable performance, and can be easily wired.

And the photo couplers 10 and 12 that are provided after the photo couplers 10 and 12, and are continuously provided for a predetermined time t1 from when a voltage change is detected during the opening / closing operation of the opening / closing tool and when the opening / closing tool is stopped. A timer circuit 6 for closing the illumination switch 15 connected to the power supply line 4 and continuously lighting the illumination body is provided.

Further, as described in claim 2, the photocouplers 10 and 12 and the timer circuit 6 constituting the illuminating device may be incorporated in the housing of the illuminating body 3.

[0011]

The operation of the structure in which the illumination device is linked with the opening and closing of the shutter will be described. The push-up button P for raising the shutter is described.
When BU is pressed, the self-holding circuit MCU of the shutter is self-held to raise the shutter, and the LED 10 is turned on via the lead-in wire 7. As a result, the timer circuit 6 passes through the phototransistor 12 and the lighting switch 15
Is closed and the illumination body 3 is turned on while the shutter is rising. When the shutter reaches the upper limit position, the shutter is stopped by opening the limit switch LSU. The timer circuit 6 is activated upon detection of the voltage change at this time, and the lighting switch 15 is continuously kept closed for a predetermined time t1. Thus, the illumination body 3 can be continuously turned on for a predetermined time t1 after the shutter starts to move up and after reaching the upper limit position.

When the push button PBU for raising is pressed, the electromagnetic relay MCU is activated, the relay contact MCU is connected, the rotation direction of the motor M is regulated on the power supply line 21, and the shutter is raised. Similarly, the push-down button PBD is the electromagnetic relay MC.
D, the relay contact MCD is actuated, the motor M rotates in the reverse direction, and the shutter is lowered. Then, when the stop push button PBS is pressed, the circuit is disconnected, and both lifting and lowering are immediately stopped. Also, when the shutter rises and reaches the upper limit position,
The upper limit switch LSU is opened, the shutter stops at this upper limit position, and at the lower limit position, the lower limit limit switch LSD stops the shutter at the lower limit position. The electromagnetic relay and the relay contacts MCU and MCD form a self-holding circuit for the shutter.

Further, the dotted line portion shown in FIG. 2 is a portion externally connected by wiring. Then, the shutter and the lighting device are installed as shown in FIG. Figure 3

To provide.

The end 7a of the service wire 7 of the lighting device 1
Is connected to any one of the contacts B3 and B4 shown in FIG. For example, when the end 7a of the service wire 7 is connected to the contact B3 (P1 in FIG. 2), the raising push button PBU constitutes the switch means 8 instead of the switch means 8 of the lighting device 1. As a result, the lift push button PB
When U is pressed, the lighting device 1 is continuously turned on as the shutter is raised for a predetermined time.

Further, the timer circuit 6 indicates that the shutter has reached the upper limit position and that the shutter has stopped by changing the voltage (0V).
To the predetermined time t1
During this period, this continuous lighting is continued. As described above, when the illumination device of the present invention is applied to the shutter, the timer circuit 6 shown in FIG. 1 does not use the switch operation of the switch means 8 as a trigger, but the shutter moves to the upper limit position or the lower limit position. The illumination switch 15 is configured to be closed for a predetermined period of time t1 by using a time point when it has reached and stopped as a trigger. As a result, the illumination body 3 is continuously lit by the shutter self-holding circuit MCU or MCD during the shutter up / down period, and then the predetermined time t1 is continued even after the shutter is stopped.
During the period, the lighting body 3 can be continuously turned on.

The LED 10 is turned on while the shutter self-holding circuit MCU is holding itself, activates the phototransistor 12, and closes the illumination switch 15. Further, from the time when the shutter reaches the upper limit position and the limit switch LSU is opened, the timing of the timer circuit 6 starts, and the illumination switch 15 is continuously closed for a predetermined period t1 to make the illumination body 3
Is continuously supplied, the shutter reaches the upper limit position, and even after the shutter is stopped, the shutter keeps lighting for a predetermined time t1 (for example, 5 minutes).

When the end 7a of the lead-in wire 7 is connected to the contact B4 (P2 in FIG. 2), the descending push button PBD constitutes the switch means 8 instead of the switch means 8 of the lighting device 1. become. As a result, the lowering push button P
When BD is pressed, the lighting device 1 continuously lights the lighting body 3 after the pressing, until the shutter reaches the lower limit position, and after the shutter reaches the time t1.

Since the lead-in wire 7 of the lighting device 1 is connected to these contact points B3 and B4, these points P1 and P4 are connected.
When 2 is taken from the operation panel 22, the wiring is provided between the operation panel 22 and the lighting device 1. On the other hand, this point P1,
When P2 is taken from the raising / lowering control unit 24, wiring is provided between the raising / lowering control unit 24 and the lighting device 1.
These can be appropriately selected depending on the installation location of the lighting device 1 and the degree of wiring work. In each case, the service wire 7 is composed of one wire, the number of wires is small, and wiring work can be facilitated.

Further, the lighting device 1 of the present invention having the above-mentioned structure.
According to this, it is possible to easily retrofit the already installed shutter. That is, the push-up button PBU or the push-down button PBD of the operation panel 22 or the raising / lowering control unit 24 in which the service wire 7 is already installed, or these PBs.
The illuminating body 3 can be continuously turned on for a predetermined period in conjunction with the raising and lowering of the shutter by simply connecting to either P1 or P2 of the U and PBD connection points. This interlocking lighting operation makes it possible to brighten a dark place when entering or leaving a warehouse, a garage, or the like, thereby confirming the existence of an object when entering or exiting, and preventing the risk of a contact accident with the object. FIG. 5 is a flowchart showing the opening / closing operation of the shutter and the linked state of the lighting device 1.

Further, although the timer circuit 6 of the above-described embodiment is configured to continuously turn on the illumination body 3 for a predetermined time t1 after the shutter reaches the upper limit position or the lower limit position,
Alternatively, it may be configured to be activated at the operation timing of the push buttons PBU and PBD. In this case, it is desirable that the predetermined time t1 is set to a time that is longer than the time required to open and close the shutter. It should be noted that as shown by the dotted line in FIG. 3 (b), the illumination device 1 may be entirely provided in the shutter case 30 of the shutter, and in this case, wiring can be further reduced. Also,
The lighting control unit 2 of the lighting device 1 may be provided in the shutter case 30, and the light emitting body 3 may be provided on a wall, a ceiling, or the like, which is separated from the shutter case 30. Further, the lighting device 1 may be provided in the lighting body 3. Furthermore, in the above-described embodiment, the case where the opening is provided with the shutter has been described as an example. However, in addition to the shutter, an opening / closing tool such as a door, a curtain, a shutter, and a blind is provided so as to be openable / closable in the opening. It is also possible to adopt a configuration, and in this case also, the same effect as in the above embodiment can be obtained.

[0029]

According to the illuminating device of the present invention, it is possible to provide a predetermined time even after the shutter is being opened or closed and after the opening and closing of the shutter only by wiring one end of the lead wire to one end of the push button for opening and closing the opening and closing device such as the shutter. During that time, the illumination body can be continuously and stably turned on. As a result, the number of wirings required for the lighting device can be minimized, and the wiring work can be simplified. Further, since the lead-in wire only needs to be connected to either the shutter opening / closing operation panel or the opening / closing control panel which is one end of the opening / closing push button, the lighting device of the present invention can be easily retrofitted to an existing shutter. be able to. Furthermore, by providing the illuminating device in the housing of the illuminating body, it can be handled as an illuminating body capable of obtaining the above effect without taking up space.
