[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator lighting device, and more particularly, to an elevator lighting device that automatically detects the absence of call registration and turns off the light automatically.

[0002]

[Prior art]

 In order to reduce power consumption and extend the operating life of lighting lamps, the lighting system for elevators turns off the lights inside the car when the elevator is in a non-operating state, and when the call registration occurs, the car The lights inside are turned on. For example, Japanese Unexamined Patent Publication No. 56-48372 discloses this kind of technology, and in the technology of the disclosure, the illumination inside the car is turned off after a predetermined time has elapsed since the call registration was lost. This prevents the lights from being turned on and off too often.

[0003]

[Problems to be solved by the device]

 In the lighting device according to the above disclosure, turning off the lights in the car may confuse passengers who happen to be in the car. For example, when a worker cleaning a building gets in a car after stopping the elevator to clean the car, the light in the car may suddenly turn off. In this way, if the light in the car suddenly goes off, the worker may feel uneasy, and a surprised worker may operate the emergency call button in the car, thinking that the elevator is out of order. . In this way, when the emergency button in the car is operated, the building manager and, in some cases, the service personnel of the elevator service company will be able to enter the site even though no abnormality has occurred in the elevator. I will rush.

The present invention has been made in view of the current state of the above-described elevator lighting device of the type described above, and an object thereof is to avoid a sudden turn-off of the light in the car and provide a prior notice. An object is to provide a lighting device for an elevator that is turned off later.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has an unregistered detecting means for detecting the absence of call registration and outputting a detection signal, an extinguishing means for extinguishing a lighting device in a car, and a car in the car. And a guide means for guiding to turn off the car interior lighting, and for causing the guide means to perform the guidance after a predetermined time from the output of the detection signal, and after the guidance is finished, the turning-off means And a control means for turning off the light.

[0006]

[Action]

 With such a configuration, when the non-registration detecting means detects that there is no call registration and outputs the detection signal, the control means drives the planning means after a predetermined time from the output of the detection signal to guide the guide. By means of means, guidance will be given to turn off the light in the car. Then, when the guidance by the guiding means is completed, the extinguishing means is driven by the control means, and the lighting device in the car is extinguished by the extinguishing means.

【Example】

 An embodiment of the present invention will be described below with reference to FIG. Here, FIG. 1 is a circuit diagram showing the configuration of the embodiment.

As shown in FIG. 1, between the DC power supply terminals P and N, a lighting switch 1 for lighting the lighting device in the car, a normally-closed contact 5 a of a relay 5, which will be described later, and a lighting device 2 as a lighting device. Are connected in series with each other. Similarly, when the elevator call registration (hall call and car call) is lost between the DC power supply terminals P and N, the normally open contact 3a that closes and the state without call registration reaches the preset time. Then, the extinguishing timer 4 and the extinguishing relay 5 in which the contacts are closed and energized are connected in series.

In addition, when the elevator call registration (hall call and car call) is lost between the DC power supply terminals P and N, the normally open contact 3b is closed, and the state without call registration is a preset time. The announcement timer 6 and the announcement relay 7 are connected in series with each other when the contact is closed. Similarly, a normally open contact 7a of the announcement relay 7 and an announcement circuit 8 for performing an announcement operation are connected in series between the DC power supply terminals P and N.

Here, the normally-open contacts 3a and 3b constitute non-registration detecting means, and the relay 5 and the normally-closed contact point 5a constitute extinguishing means. Further, the turning-off timer 4 and the announcement timer 6 constitute a control means for controlling the announcement and the turning-off, and the setting time of the turning-off timer 4 is set to be slightly longer than the setting time of the announcement timer 6. is there. The turning-off timer 4 and the announcement timer 6 are configured such that the contacts are closed in the energized state, and the contacts are opened when the energization is interrupted, and the counting is reset again. In addition, the announcement circuit 8, which is a guide means, provides voice information for guidance that is preset in the operating state, for example, "There is no call registration, so the lights in the car will be turned off to save power." It has a function to output information as voice from a speaker installed in the car. Then, the set time of the aforementioned extinguishing timer 4 is set slightly longer than the announcement time of this voice information.

Next, the operation of the embodiment having such a configuration will be described. In the normal operating state of the elevator, the lighting switch 1 is in the closed state, the normally closed contact 5a is also closed, and the illumination lamp 2 in the car is on. In this state, the car operates between floors in response to hall call registration or car call registration.If these call registrations are lost, the car goes into a standby state at a predetermined floor, Since the normally open contacts 3a, 3b are closed, the announcement timer 6 and the extinction timer 4 start counting.

As described above, the set time of the announcement timer 6 is set shorter than the set time of the turn-off timer 4, and in the embodiment, 2 minutes and 50 seconds after the call registration disappears. The announcement timer 6 counts up, a closed circuit is formed by the DC power supply terminal P, the normally open contact 3b, the announcement timer 6, the relay 7 and the DC power supply terminal N, and the relay 7 is energized. When the relay 7 is energized, the normally open contact 7a is closed, and a closed circuit is formed by the DC power supply terminal P, the normally open contact 7a, the announcement circuit 8 and the DC power supply terminal N, and the announcement circuit 8 is activated to drive the vehicle. From the speaker in the car, the voice information "There is no call registration, so the light in the car is turned off to save power" is output.

Immediately after the end of the output of the voice information, the extinguishing timer 4 completes counting for 3 minutes, and the DC power supply terminal P, the normally open contact 3a, the extinguishing timer 4, the relay 5, and the DC power supply terminal. A closed circuit is formed by N, and the relay 5 is energized. When the relay 5 is energized, the normally closed contact 5a is opened, the power supply to the lamp 2 is cut off, and the lamp 2 is turned off. In this way, when call registration occurs for an elevator on standby with the car lamp 2 turned off, the normally open contacts 3a, 3b are opened, so that the relays 5, 7 are The contacts of the deenergizing and extinguishing timer 4 and the announcement timer 6 are opened and reset. Then, since the relay 5 is deenergized, the normally-closed contact 5a is closed, the illumination lamp 2 is turned on, and the car starts operation in response to the call registration.

As described above, according to the embodiment, when the illumination lamp 2 in the car is turned off, an announcement to the effect that the light will be turned off is given in advance in the car, so that a cleaning worker or the like can do so. Sometimes it prevents the passengers in the car from being surprised and confused by a sudden turn off.

[0015]

[Effect of device]

 As described above, according to the present invention, when there is no call registration for the elevator, the guide means guides the lights in the car to be turned off, and then the turn-off means is used. Since the lighting system in the car is turned off, the passengers present in the car at that time are prevented from being confused, unnecessary emergency calls are not issued, and the elevator operates smoothly.
