Description
제 1 도는 본 고안의 회로도.1 is a circuit diagram of the present invention.
본 고안은 옥내가설 소방용 고주파 동작방식의 비상형광등에 관한 것으로 A.C 전원을 정류회로에서 D.C로 변성 출력시켜 고주파 발진회로에서 고주파 고압의 안정된 A.C 전원을 형광등에 걸리도록 하여 쵸크(choke)를 사용치 않거나 또는 아주 작게 만들므로서 쵸크에 의한 전력손실을 방지함과 동시에 형광등의 수명을 길게 한 것이다.The present invention relates to an emergency fluorescent lamp of high frequency operation method for indoor construction fire fighting. In addition, by making it very small, it prevents power loss due to choke and extends the life of fluorescent lamp.
종래 비상형광등은 저주파를 사용 기동 임피단스(operating impedamce)를 안정하게 하기 위하여 안정기와 스타트 램프 즉 쵸크를 사용하였다.Conventional emergency fluorescent lamps use a low frequency and a stabilizer and a start lamp, or choke, to stabilize the operating impedamce.
쵸크의 사용은 전력손실을 가져오게 됨과 동시에 발열에 의하여 밀폐된 상태에서 내부 온도가 60℃까지 올라가 구성소자의 열에 의한 성능감소를 초래하여 수명을 단축케 하는 등의 결점이 있었고 또 정전시는 충전용 밧데리를 비상전원으로 사용하고 비상회로의 스윗칭은 리레이를 사용하여 형광등을 교환하여 대단히 복잡하고 고장이 많은 결점이 있었다.The use of choke leads to a loss of power, and at the same time, the internal temperature rises to 60 ° C in a sealed state due to heat generation, resulting in a decrease in performance due to heat of the component, which shortens the lifespan. The emergency battery was used as an emergency power source, and the switching of the emergency circuit had a very complicated and troublesome defect by replacing a fluorescent lamp using a relay.
본 고안은 이러한 종래의 저주파 동작방식의 비상형광등의 결점을 제거하고 안정된 고주파 전원을 사용하므로서 안정기와 스타트 램프를 사용치 않고 따라서 종래의 쵸크에서 발생되는 전력손실을 제거함과 동시에 형광등의 효율을 향상시켜 수명을 연장하도록 하고 또 비상회로의 스윗칭을 간단히 구성한 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention eliminates the shortcomings of the conventional low frequency operation type emergency fluorescent lamp and uses a stable high frequency power supply, thereby eliminating the power loss generated by the conventional choke and improving the efficiency of the fluorescent lamp without using a ballast and a start lamp. To extend the life and to simply configure the switch of the emergency circuit described in detail by the accompanying drawings as follows.
본 회로의 점등방식은 상용전원 공급시 트랜스 T로 전압강하하여 다이오드 D1D2로 정류하여 콘덴서 C1으로 평활하여 직류 DC 12V의 전압을 얻는다.The lighting method of this circuit is voltage drop to transformer T when supplying commercial power, rectified to diode D 1 D 2 and smoothed to capacitor C 1 to obtain DC DC 12V.
이 얻어진 전압은 다이오드 D5를 통해 D점에 가해지며 이 가해진 전압에 의해 발진회로가 동작하여 비상형광등(5)를 점등하고 또한 저항 R4를 통해 A점에 가해진 전압은 트랜지스터 TR3를 역바이어스로 만드는데 이 트랜지스터 TR3의 역바이어스는 다이오드 D3, D4로 양파정류되어 저항 R1과 실리콘 제어소자 SCR1을 통한 충전전압 11V인 B점의 전압에 의해서 이루어진다.The obtained voltage is applied to the point D through the diode D 5 , and the oscillation circuit operates by the applied voltage to light the emergency fluorescent lamp 5, and the voltage applied to the point A through the resistor R 4 reverse biases the transistor TR 3 . The reverse bias of this transistor TR 3 is rectified by diodes D 3 and D 4 and is driven by the voltage at point B, which is the charging voltage 11V through the resistor R 1 and the silicon control element SCR 1 .
실리콘 제어소자 SCR1은 저항 R1, R2를 통해 Gate전압이 가해져 도통되며 실리콘 제어소자 SCR1이 도통됨으로 밧데리 BAT에는 충전 전류가 흘러 충전되며 충전이 지속됨에 따라 밧데리 BAT 단자 전압은 상승한다.Silicon control element SCR 1 conducts by applying gate voltage through resistors R 1 and R 2. As silicon control element SCR 1 conducts, a charge current flows in battery BAT. As the charge continues, the battery BAT terminal voltage increases.
단자전압이 상승하여 제너다이오드 ZD1의 설정전압 11V보다 높을 때는 제너다이오드 ZD1에는 역방향 전류가 흘러 트랜지스터 TR1의 Base에 Bias를 가해 트랜지스터 TR1을 ON시켜 충전전류를 제어한다.When higher than the set voltage of 11V the Zener diode ZD 1 and the Zener diode ZD 1 terminal voltage rises, the reverse current flow is applied to a Bias to the Base of the transistor TR 1 to turn ON the transistor TR 1 and controls the charging current.
그러므로 밧데리 BAT가 과충전되는 것을 방지한다.This prevents the battery BAT from being overcharged.
스윗칭 회로의 동작은 상용전원 공급시에 저항 R4를 통해 A점에 가해지는 전압이 트랜지스터 TR3의 B점의 전압보다 높아 트랜지스터 TR3는 OFF되며 트랜지스터 TR3가 OFF됨에 따라 트랜지스터 TR2의 Base에도 Bias전압이 가해지지 못하므로 트랜지스터 TR2도 따라서 OFF된다.Operation of Switching circuit of the transistor TR 2 as a commercial power source to supply a voltage to be applied to the point A via the resistor R 4 becomes higher than the voltage of the point of the transistor TR 3 B transistor TR 3 is OFF and the transistor TR 3 OFF Since the bias voltage is not applied to the base, the transistor TR 2 is turned off accordingly.
그러므로 B점의 밧데리 BAT전압이 D점으로 연결되지 못하고 다이오드 D5를 통한 C점의 전압이 D점에 가해져 발진회로를 동작시킨다. 또한 상용전원의 공급이 중단될 때는 변압기 T에서는 전압이 얻어지지 않으므로 C점의 전압은 0이 된다.Therefore, the battery BAT voltage of point B is not connected to point D, and the voltage of point C through diode D 5 is applied to point D to operate the oscillation circuit. In addition, when the supply of commercial power is interrupted, no voltage is obtained from the transformer T, so the voltage at the point C becomes zero.
그러므로 저항 R4를 통해 트랜지스터 TR3를 역바이어스로 하던 전압도 안걸리게 된다.Therefore, the voltage used to reverse bias transistor TR 3 through resistor R 4 is also not applied.
따라서 밧데리 BAT 전압이 저항 R5, R6와 제너다이오드 ZD2를 통해 방전하며 저항 R5에 의해 전압강하된 전압이 트랜지스터 TR3Base에 가해지므로 트랜지스터 TR3가 순방향 Bias로 ON되며 트랜지스터 TR3가 도통됨으로 인해 트랜지스터 TR2도 도통되여 B점의 밧데리 BAT전압이 D점으로 연결되여 발진회로를 정전없이 계속 동작시켜 비상형광등(5)를 점등한다.Therefore, the battery BAT voltage is discharged through the resistors R 5 , R 6 and the zener diode ZD 2 , and the voltage dropped by the resistor R 5 is applied to the transistor TR 3 Base, so that the transistor TR 3 is turned on with the forward bias, and the transistor TR 3 is turned on. As the transistor is turned on, the transistor TR 2 is also turned on, and the battery BAT voltage at point B is connected to point D, and the oscillating circuit is continuously operated without power failure to turn on the emergency fluorescent lamp 5.
밧데리 BAT전압이 발진회로로 방전하여 전압이 떨어져 제너다이오드 ZD2의 설정 전압 7V 이하가 되면 제너다이오드 ZD2를 통해 흐르던 역전류가 차단됨으로 A점의 전압은 B점과 같게 된다. 그러므로 트랜지스터 TR3의 Base의 Bias전압이 0이 되여 트랜지스터 TR3를 OFF시키고 트랜지스터 TR3가 OFF됨에 따라 트랜지스터 TR2도 OFF되여 밧데리 BAT전압이 발진회로로 방전하는 것을 막는다.When the battery BAT to the voltage discharged by the oscillation circuit voltage is the Zener diode off below the set voltage of the Zener diode ZD 2 7V voltage of the point A in the reverse current flowing through the ZD 2 is a blocked is equal to B point. Therefore, the bias voltage at the base of transistor TR 3 becomes 0, which turns off transistor TR 3 , and when transistor TR 3 is turned off, transistor TR 2 is also turned off to prevent battery BAT voltage from discharging to the oscillating circuit.
그러므로 밧데리 BAT가 과방전으로 인한 수명단축을 막는다.Therefore, the battery BAT prevents shortening of life due to over discharge.
이와 같이 본 고안은 통상의 A.C전원(1)이 정류회로(2)에 의하여 맥동계수가 적은 D.C 12V로 변류하여 고주파 발진회로(4)에 의하여 고주파 고압의 안정된 A.C로 하여 비상형광등을 점등하므로 종전과 같이 저주파 전원을 사용하므로서 기동 임피던스(operating impedace)를 안정하게 하기 위하여 안정기와 스타트램프 즉 쵸크(choke)를 사용할 필요가 없으며 따라서 쵸크에 의한 전력손실을 제거할 수 있어 형광등의 효율을 높이고 전력소모량을 감소시키는 경제적 효과가 있다.As described above, the present invention is a conventional AC power supply 1 is converted to a DC 12V with a small pulsation coefficient by the rectifier circuit 2, and the emergency fluorescent lamp is turned on by the stable high-frequency high-voltage AC by the high-frequency oscillation circuit (4). By using a low frequency power supply like this, it is not necessary to use a ballast and a start lamp, or choke, to stabilize the operating impedance, thus eliminating the power loss caused by the choke, thus increasing the efficiency of fluorescent lamps and reducing the power consumption. There is an economic effect to reduce.
또 본 고안은 스윗칭 회로(3)를 전자소자로 구성하였으므로 종래의 리레이에 비하여 신뢰도가 높고 수명이 길다.In addition, since the switching circuit 3 is composed of electronic elements, the present invention has higher reliability and longer life than conventional relays.
