Description
본 고안은 단전용 비상조명장치에 관한 것으로, 보다 상세하게 내부에 충전기와 전자식 안정기가 내설되어 있어 상시 일정전압 이상의 충전을 진행하며, 단전 개시시 B접점의 스위칭으로 자동 점등되는 비상 조명등을 내설함으로써 가정에서단전 상황발생시 신속하게 대피할 수 있도록 한 단전용 비상조명장치에 관한 것이다.The present invention relates to an emergency lighting device for single use, and more specifically, a charger and an electronic ballast are installed in the inside, so that charging is performed at a constant voltage or higher, and by initiating an emergency light that is automatically turned on by switching of the B contact at the start of power failure. The present invention relates to a single emergency emergency lighting device that can be quickly evacuated in case of a power failure situation in the home.
주지된 바와 같이, 일반적인 비상구 안내판은 단순히 비상구의 위치를 안내하는 문구 또는 기호와, 이를 외부적으로 표시하여 주는 전등으로만 구성되어 있어 단순 표지 역할이외에는 별도의 기능을 수행하지 못하였던 바, 평상시 사람들은 비상구 안내판이 어디에 있는지 눈여겨보지 않으므로 위급상황이 발생하거나, 화재발생시 각종 오염가스나 발생연기로 인해 시야가 확보되지 못하거나, 단전이 되어 깜깜할 때에는 심리적으로 당황하여 비상구의 위치를 쉽게 찾지 못하게 되며, 이로 인해 많은 인명피해가 발생되고 있다.As is well known, the general emergency exit signboard is composed of only a phrase or a sign for guiding the location of the emergency exit, and a light that externally displays the emergency exit sign, and thus has not been able to perform any function other than a simple sign. Does not notice where the emergency exit signs are, so when an emergency situation occurs, or when there is a fire, the field cannot be secured due to various polluting gases or smoke, or when it is dark due to power failure, it is difficult to find the location of the emergency exit. As a result, many casualties are caused.
따라서, 최근에는 다양한 기능을 갖춘 각종 비상구 안내판이나 비상 유도등이 개발되어져 인구 밀집지역이나 화재 우려지역, 재난 우려지역에 속속 장착되어지고 있다.Therefore, in recent years, various emergency exit guides and emergency guidance lamps with various functions have been developed, and are being installed one after another in crowded areas, fire concern areas, and disaster concern areas.
그러나, 실상은 인구가 더욱 밀집된 거주지역인 주택 등에 이러한 비상 유도등이 설치되어져 있지 않으므로 재난상황 발생시, 특히 야간 재난상황 발생시 거주자들이 당황하게 되어 큰 인명사고를 일으키게 된다.However, in reality, such emergency induction lamps are not installed in houses that are densely populated, so residents may be embarrassed when a disaster occurs, especially when a night disaster occurs.
특히, 야간에 화재가 발생되어 단선되거나, 화재없이 단선될 경우, 미리 촛불이나 렌턴 등의 비상 조명기구를 갖추지 않아서 비상시 조명기능을 수행하지 못하고, 예비 비상조명기구를 준비해둔 거주자들도 당황하여 비상 조명기구를 찾지 못할 우려가 매우 높다는 문제가 있다. 또한, 촌각을 다투는 시급한 재난 상황 발생시 조명기구를 찾는 시간 소요로 인해 큰 인명피해가 발생할 수 있다는 문제가있었다.In particular, if a fire occurs at night or is disconnected without a fire, emergency lighting devices such as candles or lanterns are not provided in advance, and lighting functions cannot be performed in an emergency, and residents who have prepared emergency emergency lighting devices are embarrassed. There is a problem that there is a high possibility of not finding a lighting fixture. In addition, there was a problem that large casualties may occur due to the time required to find a lighting fixture when an urgent disaster situation confronts the village.
또한, 종래에도 형광등에 비상용 조명을 설치한 경우가 있으나, 이 경우 해당 형광등에 별도의 전구를 설치하고, 정전대비용 형광등 안정기가 단상 3선식으로 구성되어 있어서 건축물 전기 배선을 설계할 때 건물의 주전원에서 1회선을 인출하여 등기구까지 배선하여야 하는 불리함이 있었다.In addition, conventionally, emergency lighting may be installed in the fluorescent lamp, but in this case, a separate electric bulb is installed in the fluorescent lamp, and the main power supply of the building is used when designing the electrical wiring of the building because the antistatic charge ballast fluorescent ballast is composed of a single-phase three-wire type. There was a disadvantage in that it was necessary to draw one line in and to wire it to the luminaire.
본 고안은 상기한 종래 기술의 사정을 감안하여 이루어진 것으로, 내부에 충전기와 전자식 안정기가 내설되어 있어 상시 일정전압 이상의 충전을 진행하며, 단전 개시시 B접점의 스위칭으로 자동 점등되는 비상 조명등을 내설함으로써 가정에서 단전 상황발생시 신속하게 대피할 수 있도록 한 단전용 비상조명장치를 제공함에 그 목적이 있다.The present invention has been made in view of the above-described prior art, and a charger and an electronic ballast are built in there, so that charging is performed at a constant voltage or higher, and by incorporating an emergency lamp which is automatically turned on by switching of the B contact at the start of power failure. Its purpose is to provide a single emergency emergency lighting device that can be evacuated quickly in the event of a power outage at home.

이하, 본 고안에 대해 도면을 참조하여 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.
도 1은 본 고안의 일실시예에 따른 단전용 비상조명장치의 외형을 도시한 사시도이다.1 is a perspective view showing the appearance of a single-use emergency lighting device according to an embodiment of the present invention.
이를 참조하면, 본 고안의 일실시예에 따른 단전용 비상조명장치(2)는 내부에 충전기와 전자식 안정기가 내설되어 있어 상시 일정전압 이상의 충전을 진행하며, 단전 개시시 B접점의 스위칭으로 자동 점등되는 비상 조명등을 내설함으로써 가정에서 단전 상황발생시 신속하게 대피할 수 있도록 한다.Referring to this, the emergency lighting device for single use according to an embodiment of the present invention (2) has a charger and an electronic ballast in the built-in to always charge more than a certain voltage, and automatically turns on by switching of the B contact at the start of power failure. By providing emergency lights, you can evacuate quickly in case of a power outage in your home.
단전용 비상조명장치(2)는 외형은 일반 형광등 장치와 마찬가지로 형광등(50)을 요입한 하우징(3)과, 내부 회로기판(8)으로 이루어져 있으며, 상시 충전된 배터리 전원을 단전시 사용하기 위해 인버터와 전자식 안정기(60)가 구성되어져 있다.The emergency lighting device for single use (2) is made up of a housing (3) and an internal circuit board (8) in which a fluorescent lamp (50) is inserted in the same way as a general fluorescent lamp device. The inverter and the electronic ballast 60 are comprised.
도 2는 본 고안의 일실시예에 따른 단전용 비상조명장치를 나타내는 블록도이며, 도 3은 본 고안의 일실시예에 따른 단전용 비상조명장치를 나타내는 회로도이다.2 is a block diagram showing a single emergency emergency lighting apparatus according to an embodiment of the present invention, Figure 3 is a circuit diagram showing a single emergency emergency lighting apparatus according to an embodiment of the present invention.
이를 참조하면, 본 고안의 일실시예에 따른 단전용 비상조명장치(2)는 AC 220V의 전원과, 형광등(50), 전자식안정기(60)와, 220V의 교류전원에 연결된 릴레이(RL1)와, 전압강하를 위한 변압기(T1)가 구성되며, 정류용 브리지 다이오드(D1∼D4)와 배터리(BAT; 30)로 구성된 충전회로(30)와, 다수의 콘덴서(도시 생략)와 저항(도시 생략)과 다이오드와 트랜지스터(도시 생략)와 릴레이(RL2)로 이루어진 정전감지회로(20)가 구성된다. 이때, 정전감지회로(20)는 공지된 기술이므로 이에 대한 설명은 생략한다.Referring to this, the emergency lighting device for single use according to an embodiment of the present invention is a power supply of AC 220V, fluorescent lamp 50, electronic ballast 60, and a relay (RL1) connected to AC power of 220V and And a transformer T1 for voltage drop, a charging circuit 30 composed of rectifying bridge diodes D1 to D4 and a battery BAT 30, a plurality of capacitors (not shown) and a resistor (not shown). ), And an electrostatic detection circuit 20 composed of a diode, a transistor (not shown), and a relay RL2. In this case, since the blackout detection circuit 20 is a known technology, description thereof will be omitted.
또한, 그 내부에 다수의 저항과 콘덴서와 코일과 발진트랜스, 푸쉬풀회로를 구성하고 있는 복수개의 트랜지스터로 이루어진 인버터회로(40)를 포함하여 구성되는 바, 그 인버터회로(40) 역시 공지 기술이므로 생략한다.In addition, the inverter circuit 40 includes a plurality of resistors, capacitors, coils, oscillation transformers, and push-pull circuits therein, and the inverter circuit 40 is also known in the art. Omit.
전원은 통상의 AC전압으로서, 복수개의 단자를 통해 220V가 인가되게 구성되어져 있으며, 어느 한 단자에는 스위치(SW)가 연결되어 있다. 도 2에 도시된 바와 같이, 다수의 전기 소자들은 대지에 접지되어져 있다.The power source is a normal AC voltage, and 220V is applied through a plurality of terminals, and a switch SW is connected to one terminal. As shown in FIG. 2, a plurality of electrical elements are grounded to the ground.
교류전원(AC 220V)이 인가되면, 어느 한 단자에 220V의 전위가 인가되고, 다른 단자에 0V의 전위가 인가되며, 이때 제 1 릴레이(RL1)가 구동되고, 전원의 투입여부에 따라 스위칭되는 접점(a1∼a4)에 의해서 전자식안정기(60)가 형광등(50)을 점등하게 된다.When AC power 220 V is applied, a potential of 220 V is applied to one terminal, and a potential of 0 V is applied to the other terminal. At this time, the first relay RL1 is driven and switched according to whether power is supplied. The electronic ballast 60 turns on the fluorescent lamp 50 by the contacts a1 to a4.
동시에, 상기 정전감지회로(20)의 제 2 릴레이(RL2)가 기동하지 않게 되어 그 제 2 릴레이(RL2)와 연동되는 접점이 오프상태가 됨으로써 배터리(BAT)와 인버터회로(40)의 연결이 차단된다. 또, 이때 전원으로부터 투입된 교류전압은 변압기(T1)와 정류용 브리지 다이오드(D1∼D4)를 통과하면서 DC로 정류되며, 정류 전압은 배터리(BAT)를 충전한다.At the same time, the second relay RL2 of the power failure detection circuit 20 does not start, and the contact interlocked with the second relay RL2 is turned off, thereby connecting the battery BAT to the inverter circuit 40. Is blocked. At this time, the AC voltage supplied from the power supply is rectified to DC while passing through the transformer T1 and the rectifying bridge diodes D1 to D4, and the rectified voltage charges the battery BAT.
이와 반하여, 단전시나 정전시에는 상기 스위치(SW)가 오프상태로 되면서, 제 1 릴레이(RL1)가 구동하지 않게 되며, 상기 접점(a1~a4)이 도시된 바와 같이, 전자식안정기(60)와 형광등(50)의 접속상태를 해제하게 된다. 또한, 접점(a2,a3,a4)이 인버터회로(40)와 연결되게 스위칭 된다. 이 경우라면, 상기 배터리(BAT)는 충전되지 않는다.On the contrary, when the switch SW is turned off in the case of power failure or power failure, the first relay RL1 is not driven, and the contacts a1 to a4 are shown as the electronic ballast 60. The connection state of the fluorescent lamp 50 is released. In addition, the contacts a2, a3, a4 are switched to be connected to the inverter circuit 40. In this case, the battery BAT is not charged.
상기 정전감지회로(20)는 정전시에만 제 2 릴레이(RL2)를 구동시켜 스위치를 온상태로 턴온시키는 것인 바, 즉, 제 2 릴레이(RL2)에 의해 온/오프가 제어되는 스위치는 소등스위치(SW)의 온/오프상태와 상관없이 전원단으로부터 220V의 전압이 인가될 경우에는 오프가 되고, 정전이나 단전시에 온상태가 된다.The power failure detection circuit 20 drives the second relay RL2 to turn on the switch in the ON state only during a power failure. That is, the switch on / off controlled by the second relay RL2 is turned off. Regardless of the on / off state of the switch SW, when a voltage of 220 V is applied from the power supply terminal, it is turned off, and is turned on in the case of power failure or power failure.
이와 같이 정전이 아닐 경우에는 점등을 위한 스위치의 스위칭상태와 무관하게 상기 제 2 릴레이(RL2)와 연동된 스위치가 오프 되며, DC 12V 배터리(BAT)로부터 인버터회로(40)로의 전원공급이 차단되게 된다. 그로인해, 정상 전원투입시에는 정전시와 같이 제 1 릴레이(RL1)가 동작하지 않으므로 형광등(50)이 인버터회로(40)와는 연결되지만, 정전시와 상이하게 제 2 릴레이(RL2)와 연동된 스위치가 턴오프된 상태이므로 배터리(BAT; 30)로부터의 전력공급이 차단되어 형광등(50)은 점등되지 않는다.In this case, if the power failure is not performed, the switch interlocked with the second relay RL2 is turned off regardless of the switching state of the switch for lighting, and the power supply from the DC 12V battery BAT to the inverter circuit 40 is cut off. do. Therefore, the fluorescent lamp 50 is connected to the inverter circuit 40 because the first relay RL1 does not operate as in the case of power failure during normal power-on, but is interlocked with the second relay RL2 differently from the power failure. Since the switch is turned off, the power supply from the battery BAT 30 is cut off and the fluorescent lamp 50 is not turned on.
정전시에는 상기 정전감지회로(20)의 스위칭에 의해 제 2 릴레이(RL2)가 구동되며, 그 제 2 릴레이(RL2)와 연동된 스위치가 턴온된다. 상기 스위치의 턴온으로 인해 배터리(BAT)로부터 인버터회로(40)로 DC 12V의 전압이 제공된다. 인버터회로(40)로 DC 전원이 투입되면, 그 내부의 초크코일(도시 생략), 트랜스에 의해 약 20KHz의 고주파가 발생하며, 그 고주파가 형광등(50)로 투입되어 형광등(50)이 점등되게 된다.즉, 제 1 릴레이(RL1)는 상기 형광등과 상기 전자식 안정기의 접속을 단속하게 되며, 제 2 릴레이(RL2)는 상기 배터리와 상기 인버터회로의 접속을 단속하게 된다.In the case of a power failure, the second relay RL2 is driven by the switching of the power failure detection circuit 20, and a switch interlocked with the second relay RL2 is turned on. The turn on of the switch provides a voltage of DC 12V from the battery BAT to the inverter circuit 40. When DC power is supplied to the inverter circuit 40, a high frequency of about 20 KHz is generated by the choke coil (not shown) and the transformer therein, and the high frequency is input to the fluorescent lamp 50 so that the fluorescent lamp 50 is turned on. That is, the first relay RL1 interrupts the connection between the fluorescent lamp and the electronic ballast, and the second relay RL2 interrupts the connection between the battery and the inverter circuit.
한편, 본 고안의 실시예에 따른 단전용 비상조명장치는 단지 상기한 실시예에 한정되는 것이 아니라 그 기술적 요지를 이탈하지 않는 범위내에서 다양한 변경이 가능하다.On the other hand, the single-use emergency lighting device according to an embodiment of the present invention is not limited only to the above-described embodiment is possible various modifications within the scope not departing from the technical gist.
상기한 바와 같이, 본 고안에 따른 단전용 비상조명장치는 가정에서 단선이나 정전시 자동으로 그 단선이나 정전상태를 감지하여 기충전된 배터리 전원을 이용하여 형광등을 점등시킴으로써 각종 재난사고 발생시 신속하게 대피할 수 있다는 효과가 있으며, 별도의 전선을 단지 비상용 점등기구를 위해 건물 주라인으로부터 인출하지 않아도 되므로 미관상 수려하며 편리하다.As described above, the emergency lighting device for single use according to the present invention automatically detects the disconnection or power failure state at the time of disconnection or power failure at home and turns on the fluorescent lamp by using the charged battery power to evacuate quickly in case of various disasters. It has the effect that it can be done, and it is aesthetically beautiful and convenient because it does not have to draw a separate wire from the main building line for emergency lighting.
