Description

  The present invention relates to an earthquake detection lighting device that detects the occurrence of an earthquake and turns on the illumination at the time of a power failure so that the evacuation direction can be easily seen.

  Conventionally, when a power outage occurs during an earthquake, it is dark and safe to evacuate when the earthquake occurs at night or when you are in a space where there is no window in the basement or the like and there is no natural light even in the daytime. It becomes extremely difficult. As a conventional earthquake detection lighting device that can automatically turn on the illumination lamp in order to ensure lighting in the event of a power failure accompanying such an earthquake, a battery that is constantly charged with the voltage supplied from the power plug, A lighting lamp is connected to the plug and the battery through a self-holding switch, and when the earthquake occurs, the self-holding switch is always turned on in response to the earthquake detection switch being turned on. There is known one that automatically lights up when connected to (see Patent Document 1). However, in this conventional example, unless the earthquake detection switch directly detects an earthquake, the self-holding switch will not turn on. There was a fear that it was not limited.

In addition, as another conventional example, it has a detector for crime prevention and disaster prevention, a seismic detector that senses an earthquake, and a receiver connected to the detector by an electric wire, and the receiver enters from the detector, In a disaster prevention system that outputs an alarm based on a notification that informs the occurrence of an abnormality in a fire or gas leak, and that outputs an alarm based on the detection of an earthquake from a seismic device connected to the receiver, lighting means for the detector When equipped with lighting signal output means that outputs a lighting signal that instructs lighting on the wiring between the receiver and the detector, when the detector is triggered, or when the seismic device detects an earthquake In addition, there is known a method in which a lighting signal output according to an instruction from a receiver is detected by a detector to turn on illumination means (see Patent Document 2). However, in this conventional example, since the earthquake is detected by the seismic detector, not the detector, lighting of the lighting means of the multiple crime prevention and disaster prevention detectors at the time of the earthquake is based on the earthquake detection of the seismic device. Follow the instructions of the receiver. Accordingly, when the electric wire connecting the receiver and the detector is cut during an earthquake, the illumination lighting instruction is not transmitted, and thus the illumination means of the detector may not be illuminated.

The output side of the power supply switching unit 44 is connected to a lighting circuit unit 41 connected to the lighting load unit 3, and the lighting circuit unit 41 is connected to a lighting control unit 42 that controls the lighting circuit unit 41 and the power supply switching unit 44. Yes. The lighting control unit 42 is connected to both the detection unit 6 and the communication unit 7, and an earthquake detection signal and a disaster occurrence signal are supplied from the detection unit 6 and the communication unit 7, respectively. The detection unit 6 is connected to the communication unit 7, and various detection signals detected by the detection unit 6 are transmitted from the communication unit 7 to another earthquake detection lighting device 20.

  The power plug unit 2 has an insertion plug that is directly inserted into the external outlet 30 from the apparatus main body 10, thereby forming an outlet plug type configuration, connected to the lighting device 4, and supplying AC power to the lighting device 4. To supply. The power plug unit 2 includes a power failure detection unit 8 that detects whether the AC power supply is in a power failure state, and a power plug connection detection unit 9 that detects whether the power plug unit 2 is connected to an external outlet 30. (Hereinafter referred to as a connection detection unit). The power failure detection unit 8 detects a power failure based on the presence or absence of an external AC voltage, and the detected power failure detection signal is sent to the lighting control unit 42 for controlling the power supply switching unit 44 of the lighting device 4. Further, the connection detection unit 9 detects whether or not the outlet 30 is connected, and the detected connection detection signal is sent to the lighting control unit 42 in order to control the power supply switching unit 44 of the lighting device 4 in the same manner as the power failure detection signal. It is done.

  The illumination load unit 3 is composed of illumination members such as illumination lamps, LEDs, and organic ELs. Here, a small, light and low-consumption EL is used as the illumination member so that it can be used for carrying in an emergency. In addition, the rechargeable secondary battery 5 is always charged by the charging circuit unit 43 during normal times when no disaster has occurred.

  The lighting device 4 includes a lighting circuit unit 41 that supplies a voltage for lighting the lighting load unit 3, a lighting control unit 42 that controls the lighting circuit unit 41 and the power supply switching unit 44 for lighting control, A charging circuit 43 that charges the battery 5 and a power supply switching unit 44 that switches the power supplied to the lighting circuit unit 41 are provided. The lighting control unit 42 is based on the detection signals of the earthquake detection, the power failure detection, and the connection detection from the detection unit 6, the power failure detection unit 8, and the connection detection unit 9, and the disaster occurrence signal received by the communication unit 7. The lighting circuit unit 41 and the power supply switching unit 44 are controlled. The lighting circuit unit 41 is a lighting circuit that is lit by supplying power to the lighting load unit 3, and the power supplied to the lighting load unit 3 is controlled by the lighting control unit 42 according to the surrounding brightness and the presence or absence of a person. The power switching unit 44 includes an AC power terminal to which the AC power from the power plug unit 2 is connected, a secondary battery terminal to which the secondary battery 5 is connected, and a non-powered open terminal. Under the control of the control unit 42, each terminal is switched to the lighting circuit unit 41, and the lighting load unit 3 is turned on or off.

  The detection unit 6 performs various detections such as earthquake detection, human detection for detecting a person when a person approaches, and illuminance detection for detecting the brightness of surrounding lighting. Signal and illuminance detection signal are generated. When an earthquake is detected, the detection signals of the human detection signal and the illuminance detection signal are transmitted to the lighting control unit 42 of the lighting device 4 and the communication unit 7 together with the earthquake detection signal. The lighting control unit 42 controls illumination of the illumination load unit 3 based on these detection signals.

  The communication unit 7 includes a transmission / reception circuit, and disasters such as disaster communication information including earthquakes from other earthquake detection lighting devices 20 and / or external disaster detection sensors 21, fire information from fire alarms, gas leak information, etc. The signal is received and transmitted to the lighting control unit 42 of the lighting device 4, and various received detection signals including the received disaster occurrence signal and the internally detected earthquake detection signal are sent to a plurality of other earthquake detection lights outside. Transmit to device 20. In addition, the communication unit 7 can communicate with other devices in the home and can control devices including other lighting devices in the home. That is, the communication unit 7 transmits other detection signals such as the earthquake detection signal, the human detection signal, and the illumination detection signal detected by the detection unit 6 to other earthquake detection illumination devices 20 indoors and outdoors using a wireless or wired communication line. It has a configuration that can be communicated to. Thereby, it is possible to control the power on / off of indoor home appliances when a disaster occurs. In addition, in the wireless communication of the communication unit 7, it is possible to easily communicate between neighboring earthquake detection lighting devices by incorporating a small button battery and transmitting and receiving with a weak wireless signal.

  In the earthquake detection lighting device 1 of the present embodiment configured as described above, the lighting control unit 42 controls the power supply switching unit 44 based on the earthquake detection signal, the power failure detection signal, and the connection detection signal, so The same is true when a disaster occurs), and the switching of the power supply is controlled under each condition in the case of a power failure and when the outlet is connected.

  FIG. 3 shows an operation procedure of power supply switching control. First, when the lighting control unit 42 recognizes that the power plug unit 2 is not connected to the external outlet 30 by the connection detection signal (NO in S1), the lighting control unit 42 determines that it is removed and is being used as portable lighting, and controls lighting. The unit 42 performs power source switching in the power source switching unit 44, supplies power from the secondary battery 5 to the lighting load unit 3 via the lighting circuit unit 41, and lights the lighting load unit 3 (S4). When the lighting control unit 42 recognizes that the power plug unit 2 is connected to the external outlet 30 (YES in S1), it detects an earthquake from the disaster occurrence signal received by the detection unit 6 or the communication unit 7. (YES in S2), and when the power failure detection signal from the power failure detection unit 8 recognizes a power failure in the lighting control unit 42 (YES in S3), the lighting load unit 3 passes from the secondary battery 5 through the lighting circuit unit 41. The power is supplied to (S4). When NO in S2, the AC power source is connected to the outlet 30, and since no earthquake has occurred, it is determined that the normal state is normal, and the illumination load unit 3 is turned off. For this reason, the power supply to the illumination load unit 3 is set to an open state with no power supply (S5). When NO in S3, in order to suppress the power consumption of the secondary battery 5, the power source switching unit 44 switches the AC power source to be connected to the lighting circuit unit 41, and the lighting load unit 3 is lit with the AC power source (S6). In addition, although the case where the occurrence of a disaster is an earthquake has been described as an example here, the same applies when a disaster such as another fire occurs.

  As described above, the lighting control unit 42 always charges the secondary battery 5 from the charging circuit unit 43 connected to the AC power source, and keeps the lighting load unit 3 normally usable in an emergency or the like. The power supply switching unit 44 is controlled so as to be turned off, and the power supply connection to the lighting circuit unit 41 is opened. The lighting control unit 42 illuminates the lighting load unit 3 with AC power from the outlet 30 and automatically supplies power from the secondary battery 5 only when a power failure occurs even if an earthquake occurs. Then, the illumination load unit 3 is turned on. Thereby, since the secondary battery 5 is used only at the time of a power failure at the time of a disaster, the battery consumption of the secondary battery 5 can be suppressed. In addition, when the power plug unit 2 is not connected to the outlet 30, control is performed so that power is automatically supplied from the secondary battery 5 to the lighting load unit 3. Thereby, when the apparatus main body 10 is removed from the outlet 30 in an emergency, the lighting load unit 3 is automatically turned on by the secondary battery 5 and the earthquake detection lighting apparatus 1 can be used as a portable flashlight. it can. In the earthquake detection lighting device 1, power for operation of each unit in the device other than the lighting load unit 3 is normally supplied from an AC power source, and is supplied from the secondary battery 5 during a power failure.

  Next, the illumination control method of the earthquake detection illumination apparatus 1 of this embodiment is demonstrated. FIG. 4 shows an operation procedure of the first lighting control method. First, when the detection unit 6 detects an earthquake and generates an earthquake detection signal (S101), or when the communication unit 7 receives a disaster occurrence signal from the outside (S102), the detection unit 6 detects human presence. Is detected (YES in S103), the illumination load unit 3 is turned on. Further, when the detection unit 6 does not detect a person (NO in S103), the illumination load unit 3 is also turned on in the same manner when the surrounding brightness is equal to or less than a certain illuminance value (illuminance level that can be evacuated) (YES in S104) To do. On the other hand, if the ambient brightness is not less than a certain illuminance value in S104, the illumination load unit 3 is not turned on because it is bright, and it waits until the ambient brightness becomes dark (S105). In addition, although the case where the occurrence of a disaster is an earthquake has been described as an example here, the same applies when a disaster such as another fire occurs.

  As described above, the first lighting control method is limited when a person approaches or when the brightness of surrounding lighting becomes darkness below a certain level, based on human detection and illuminance detection by the detection unit 6. By lighting up, the limited battery capacity of the secondary battery 5 can be used effectively, and the illumination load unit 3 can be lit for a long time.

  FIG. 5 shows an operation procedure of the second lighting control method. First, as in the first lighting control method, when the detection unit 6 detects an earthquake and generates an earthquake detection signal (S201), or when the communication unit 7 receives a disaster occurrence signal from the outside (S202). ) If no person is detected by the human detection of the detection unit 6 (NO in S203), and if the ambient brightness is not less than a certain illuminance value (illuminance level that can be evacuated) (NO in S204), Since there is no person in the room and it is bright, it is judged that evacuation is possible without turning on the lighting load unit 3, and the brightness of the surroundings is kept without turning on the lighting load unit 3 as in the first lighting control method. Wait until it becomes dark (S205). Next, when a person is detected by human detection by the detection unit 6 (YES in S203), and when the ambient brightness is equal to or less than a certain illuminance value (illuminance level that can be evacuated) (YES in S204), the communication unit 7 A lighting control signal is transmitted to another lighting fixture (S206). After transmitting this lighting control signal, the ambient brightness including lighting of other lighting fixtures is measured and detected (207), and the ambient brightness is greater than a certain illuminance value (a brightness value that can be evacuated). In this case, since it becomes bright and evacuation is possible, the lighting load unit 3 is not turned on and waits (S205). If NO in S208, the illumination load unit 3 is turned on because the surrounding area is dark (210). On the other hand, after transmitting a lighting control signal from the communication unit 7 to another lighting device (S206), when a lighting lighting confirmation signal indicating that the surrounding brightness is brighter than a certain illuminance value is received from another nearby lighting device (YES in S209), the ambient brightness is brighter than a certain illuminance value (a brightness value that can be evacuated), so the lighting load unit 3 is not turned on and waits until the ambient brightness becomes dark (S205). If no lighting lighting confirmation signal is received from another lighting fixture in S209 (YES in S209), the lighting load unit 3 is turned on because the surroundings are dark (210).

  As described above, in the second illumination control method, when a plurality of earthquake detection illumination devices are arranged, the lighting state of the plurality of other earthquake detection illumination devices 20 in the surrounding area is determined using the communication unit by the communication unit 7. Since it can detect and control lighting, even when its own detection unit 6 is not detecting, it is possible to turn on the nearby earthquake detection lighting device, and to promptly illuminate the escape route. Further, it is possible to prevent excessive illumination around the surroundings, use the limited battery capacity of the secondary battery 7 more effectively, and turn on the illumination load unit 3 for a longer time. In addition, since lighting control including lighting states of a plurality of surrounding earthquake detection lighting devices can be performed, it is particularly effective in a place that requires many evacuation route lighting such as hotels and inns. Here, the case where the occurrence of a disaster is an earthquake has been described as an example, but the same applies to other disasters such as fires.

  As described above, in the earthquake detection lighting device 1 according to the present embodiment, it is possible to detect an earthquake and disaster from both the detection of the earthquake from the detection unit 6 and the disaster occurrence signal from the outside by the communication unit 7. Therefore, it is possible to detect earthquakes and disasters more reliably, increase the reliability of lighting during a power failure, and quickly and reliably perform evacuation lighting. In addition, even when the detection unit 6 does not detect an earthquake at the time of the earthquake, the lighting load unit 3 can be turned on by an external disaster occurrence signal by the communication unit 7, and an external earthquake, fire, gas leak, etc. According to various disaster occurrence signals, appropriate lighting can be automatically performed according to the surrounding disaster information. Further, by transmitting the received disaster occurrence signal to another earthquake detection lighting device 20, other earthquake detection lighting devices 20 in the vicinity can be turned on even if the detection unit 6 does not detect an earthquake, and the evacuation route It is easy to guide to

  In addition, an earthquake is generated using at least one of the two signals by an earthquake detection signal generated by the detection of the earthquake by the detection unit itself and a disaster occurrence signal received from another earthquake detection lighting device received by the communication unit. Because detection can be performed, earthquake detection is highly reliable, and even if the detection unit does not operate, it is possible to detect disasters reliably with multiple received external disaster occurrence signals, and the lighting operation is reliable. Can be done well.

  Furthermore, the detection unit can perform not only earthquake detection but also human detection and brightness detection. As a result, it is turned on only when the detection unit detects that a person is approaching, or it is turned on when the ambient brightness is below a certain level due to illuminance detection. The capacity of the secondary battery (battery) can be effectively used.

  Further, since the power plug portion is directly inserted from the apparatus main body into the outlet of the external power source and connected to the power source, and is configured as a plug-in type, no special installation work is required. As a result, it can be easily removed from the outlet and carried in an emergency, so it can be used as a flashlight for emergency evacuation.

  In addition, this invention is not restricted to the structure of the said embodiment, A various deformation | transformation is possible. For example, the detection unit may include detection sensors for fire, crime prevention, gas leakage, etc. as detection means other than earthquake detection, human detection, and illuminance detection, and illumination control may be performed using these detection signals. In addition, since the plurality of earthquake detection lighting devices are connected to each other by a power line through a power plug, it is possible to communicate between the devices by power line communication using the power line.
