Description

  The present invention relates to a lighting fixture, and more particularly to an earthquake emergency light.

  Most of the victims of an earthquake are not caused by crustal movements or landslides caused by crustal movements, but by being involved in the collapse of buildings or being buried by residents. Therefore, how to quickly evacuate from a building in the event of an earthquake is an important matter for those who want to survive the earthquake.

  In the market, a type of emergency light that has been turned on in the event of a power failure has been developed. However, not all earthquakes cause blackouts. If an earthquake occurs and a power outage does not occur, such an emergency light does not necessarily turn on, and light cannot be supplied immediately in the event of an earthquake.

  Further, the conventional emergency light can be turned on or off by a user operation in a normal power supply state. Most of these conventional emergency lights are installed in residential buildings and all types of commercial or public buildings. Conventional emergency lights do not light immediately in the event of an earthquake under normal power supply conditions, so if an earthquake occurs in the middle of the night, people in the house or building should take the evacuation route before evacuating through the evacuation route. You have to turn on the conventional emergency lights that illuminate. However, due to the time lost to such a need, people in houses and buildings miss the opportunity to evacuate, resulting in a high risk of victimization or reduced survival. It can be.

  An object of the present invention is to provide an earthquake emergency light that can be turned on immediately in the event of an earthquake.

In order to achieve the object, the earthquake emergency light includes a power supply module, an LED module, a sensor module, and an MCU.
The power module is connected to an external power switch that controls power supply from an AC power outlet, and includes a power supply device and a rechargeable battery.
The power supply device has an input terminal connected to the external power switch and an output terminal.
The rechargeable battery has an input terminal connected to an output terminal of the power supply device, and an output terminal.
The LED module is connected to the power supply module and includes an LED drive circuit and an LED unit.
The LED driving circuit has an output terminal connected to the output terminal of the power supply device and an output terminal of the rechargeable battery, and an output terminal.
The LED unit has an input terminal connected to an output terminal of the LED drive circuit.
The sensor module includes a voltage sensor, a wireless communication unit, and a gravity sensor.
The voltage sensor is connected to an output terminal of the power supply device, and outputs an alarm signal when the voltage of the power supply device is detected.
The wireless communication unit outputs an alarm signal when it receives an earthquake alarm signal.
The gravity sensor outputs an alarm signal when an earthquake shake is detected.
The MCU is connected to the voltage sensor, a wireless communication unit, a gravity sensor, and an LED driving circuit. When any one of the voltage sensor, the wireless communication unit, and the gravity sensor outputs an alarm signal, the MCU controls the LED drive circuit to light the LED unit.

  When the external power switch is switched on and the AC power outlet is outputting power to the power supply device, the power supply device supplies power to the LED drive circuit. On the other hand, when detecting that the power supply device is outputting a voltage, the MCU controls the LED drive circuit to light the LED unit. For this reason, this emergency light for earthquakes can play a role as normal lighting in daily life.

When the power supply device is not supplying power because the external power switch is switched off, the MCU detects whether the wireless communication unit is receiving an earthquake warning signal or the gravity sensor is detecting an earthquake shake To do. When detecting this, the MCU controls the LED drive circuit to light the LED unit. When the external power switch is switched off, power from the rechargeable battery is consumed by the LED unit. For this reason, the emergency light for earthquakes can be turned on immediately in the event of an earthquake, reducing the time consumed by lighting the evacuation route, reducing the risk of being a victim, and increasing the survival rate. it can.
Other objects, advantageous effects, and novel configurations of the present invention will become apparent from the detailed description and drawings described below.

As shown in FIG. 1, the earthquake emergency light according to the present invention includes a power supply module 20, an LED module 30, a sensor module 40, and a microcontroller unit (MCU) 50.
The power module 20 is connected to an external power switch 10 that controls power supply from the AC power outlet 11, and includes a power supply device 21 and a rechargeable battery 22. The power supply device 21 has an input terminal connected to the external power switch 10 and an output terminal connected to the input terminal of the rechargeable battery 22. In the present embodiment, the power supply module 20 charges the power supply from the power supply device 21 and supplies it to the rechargeable battery 22. The charger 23 connected between the power supply device 21 and the rechargeable battery 22. It has further. Each of the output terminal of the power supply device 21 and the output terminal of the rechargeable battery 22 is connected to the anode of the diode 24 in order to ensure that no current feedback occurs at the output terminals of the power supply device 21 and the rechargeable battery 22. It is connected to the.

  The LED (light emitting diode) module 30 is connected to the power supply module 20 and includes an LED drive circuit 31 and an LED unit 32. The input terminal of the LED drive circuit 31 is connected to the output terminal of the power supply device 21 and the output terminal of the rechargeable battery 22. An output terminal of the LED drive circuit 31 is connected to an input terminal of the LED unit 32. In the present embodiment, the input terminal of the LED drive circuit 31 is connected to the cathode of each diode 24.

  The sensor module 40 includes a voltage sensor 41, a wireless communication unit 42, and a gravity sensor 43. The voltage sensor 41 is connected to the output terminal of the power supply device 21. When the voltage is detected, the voltage sensor 41 outputs an alarm signal. When the earthquake warning signal is received, the wireless communication unit 42 outputs the warning signal. When detecting the shaking of the earthquake, the gravity sensor 43 outputs an alarm signal. In this embodiment, the earthquake warning signal is emitted from an earthquake warning system. The earthquake warning system transmits an earthquake warning signal to a specific area such as an important public infrastructure such as a metropolitan area or a subway or a highway through a communication facility / equipment.

  The MCU 50 is connected to the voltage sensor 41, the wireless communication unit 42, the gravity sensor 43, and the LED drive circuit 31. When any of the voltage sensor 41, the wireless communication unit 42, and the gravity sensor 43 outputs an alarm signal, the MCU 50 controls the LED drive circuit 31 so that the LED unit 32 is turned on. In the present embodiment, the MCU 50 is connected to the diode 24 through the constant voltage regulator 51. The constant voltage regulator 51 stably supplies power from the power supply device 21 or the rechargeable battery 22 to the MCU 50. As shown in FIG. 3, 1st Embodiment of the determination procedure of the operation state which concerns on this invention is integrated in MCU50 of the earthquake emergency light of FIG. 1, and has the following steps.

Step s10: Start.
Step s20: It is determined whether the voltage sensor outputs an alarm signal. If so, the LED unit is turned on (step s30), and the process restarts from step s10.
Step s40: It is determined whether the wireless communication unit is outputting an alarm signal. If so, the LED unit is turned on (step s30), and the process is restarted from step s10.
Step s50: It is determined whether the gravity sensor outputs an alarm signal. If so, the LED unit is turned on (step s30), and the process is restarted from step s10. Otherwise, the LED unit is turned off (step s60), and the process restarts from step s10.

  When the external power switch 10 is switched on to supply power from the AC power outlet 11 to the power supply device 21, the power supply device 21 outputs power to the LED drive circuit 31. When the voltage sensor 31 detects that the power supply device 21 is outputting a voltage in order to control the LED drive circuit 31 and turn on the LED unit 32 in the event of an earthquake, the MCU 50 outputs a voltage. Determine if it has occurred. Since the external power switch 10 is not switched off, the LED unit 32 is always lit. Therefore, the present invention also serves as a normal lighting for a house, a workplace, and an evacuation route in daily life.

  In the event of an earthquake, when the external power switch 10 is switched off, the MCU 50 first determines whether the wireless communication unit 42 is outputting an alarm signal in order to know whether the earthquake alarm system is outputting an earthquake alarm signal. . If so, the MCU 50 instructs the LED unit 32 to light up. When the external power switch 10 is switched off, the power from the rechargeable battery 22 is consumed by the LED unit 32. Otherwise, the MCU 50 determines whether the gravity sensor 43 outputs an alarm signal in order to know whether or not the current location is shaking violently. If so, the MCU 50 instructs the LED unit 32 to light up. Otherwise, the LED unit 32 is turned off. As described above, the earthquake emergency light according to the present invention can provide light immediately in the event of an earthquake, and can reduce the time required to manually turn on the conventional emergency light. Can increase the survival rate.

  The gravity sensor 43 is easily activated even by a small earthquake with a low magnitude. In such a case, the MCU 50 continues to control the LED drive circuit 31 so that the LED unit 32 is lit. If there is no one in the house or building, the LED unit 32 continues to emit light until someone returns and turns off the LED unit 32, so considerable energy waste is inevitable. In order to cope with this situation, as shown in FIG. 4, the second embodiment of the operation state determination procedure incorporated in the MCU 50 of the earthquake emergency light of FIG. 1 is the same as the first embodiment of the operation state determination procedure. The difference is that step s70 is further provided after each of steps s40 and s50.

  Step s70: Start operating time immediately after the LED unit is turned on, determine whether the operating time has exceeded the set time, and if so, turn off the LED unit (step s60), restart from s1, otherwise , And resume from s70.

  As described above, the MCU 50 has a set time incorporated therein, and the elapsed time or the operating time is always measured after the LED unit is lit, and the operating time and the set time are compared. When the operation time exceeds the set time, the MCU 50 immediately turns off the LED unit 32 in order to prevent energy waste.

In addition, when earthquake emergency lights are not widely installed in houses and buildings, some areas may be illuminated by earthquake emergency lights and other areas may not be illuminated during an earthquake. If the unlit area is important for people to evacuate from homes and buildings, the installed earthquake emergency lights cannot perform their intended function. In order to cope with such a problem, as shown in FIG. 2, another embodiment of the earthquake emergency light according to the present invention is an earthquake emergency plug in which the electric power supply device 21 is disconnected from the external power switch 10. The adapter 12 is connected between the power supply device 21 and the external power switch 10 so that the lamp can be carried. The MCU 50 is further connected to a three-stage switch 44 that is switched to three operating states: on, off, and standby.
As shown in FIG. 5, the procedure for determining the operating state incorporated in the earthquake emergency light of FIG. 2 is as follows.

Step s10: Start Step s20: It is determined whether the voltage sensor outputs an alarm signal. If so, the LED unit is turned on (step s30), and the process is restarted from step s10.
Step s80: The operating state of the three-stage switch is determined. If the three-stage switch is on, the LED unit is turned on (step s30), and the process is resumed from step s10. If the three-stage switch is off, the LED unit is turned off (step s60), and the process restarts from step s10.
Step s40: It is determined whether the wireless communication unit is outputting an alarm signal. If so, the LED unit is turned on (step s30), and the process is restarted from step s10.
Step s50: It is determined whether the gravity sensor outputs an alarm signal. If so, the LED unit is turned on (step s30), and the process is restarted from step s10. Otherwise, the LED unit is turned off (step s60), and the process restarts from step s10.

  Steps s40 and s50 each further include step s70 that follows immediately after the LED unit is turned on. Step s70 is the same as the operating state determining means of the second embodiment incorporated in the earthquake emergency light of FIG.

  Therefore, the emergency light for earthquake can be switched so that the LED unit 32 is turned on or off by the three-stage switch 44 when the electric plug is removed from the external power switch 10. Considering the problem that some areas are illuminated by earthquake emergency lights and other areas are not illuminated, this earthquake emergency light is unplugged from the external power switch 10 connected to the AC power outlet 11. Since the switch for the earthquake emergency light can be turned on by the three-stage switch 44, it becomes a portable earthquake emergency light. Therefore, since the emergency light for earthquakes can be carried to a dark area without the emergency light for earthquakes so that the evacuation route can be seen, the time required for evacuation can be shortened, and the survival rate can be increased. .
