다음으로 본 고안의 요지인 비상등용 점등회로부(B)에 대하여 도1 및 도 2의 아래부분을 참조하여 설명한다.Next, the emergency light lighting circuit portion B, which is the subject of the present invention, will be described with reference to FIGS. 1 and 2.
비상등용 점등회로부(B)는, 도 1의 아래 부분에서 보는 바와 같이, AC 상용전원을 입력받는 전원입력부(1), 상기 입력 전원부(1)로부터의 입력된 AC전압을 감소시키는 입력전류 제어부(2), AC 전원을 정류하는 브릿지 정류부(3), 정류된 저전류로 충전되는 2차 전지(5) 및 2차 전지 충전부(4), A.C 입력전원이 입력되지 않게 되면 스위칭을 행하며 푸시풀 인버터(6) 및 2배합 회로(7)에 의해 증폭된 고 전압을 형광등용 안정기부의 전압공진부(17) 및 형광램프(18)에 인가하여 형광램프를 점등하는 전력 변환부(8)로 구성된다.As shown in the lower part of FIG. 1, the emergency lighting unit B may include a power input unit 1 for receiving AC commercial power and an input current control unit for reducing an AC voltage input from the input power unit 1. 2), the bridge rectifier (3) for rectifying the AC power, the secondary battery (5) and the secondary battery charging unit (4) to be charged with the rectified low current, switching when the AC input power is not input, pushes the inverter (6) and the power converter 8 for lighting the fluorescent lamp by applying the high voltage amplified by the double circuit 7 to the voltage resonator 17 and the fluorescent lamp 18 of the ballast for the fluorescent lamp. do.
이의 구성 소자 및 동작을 도 2의 아래 부분인 비상등용 안정기부(B)를 참조하여 더 상술한다.Its components and operation will be described in more detail with reference to the emergency light ballast portion (B) of Figure 2 below.
전원입력부(1)로 입력된 A.C 입력전압은, 캐패시터(C20)와 저항(R30)으로 구성되는 A.C입력전류 제어부(2)를 거쳐, 다이오드(D13,D14,D15,D16)로 구성되는 브릿지 정류부(3)에서 저전압 맥류전압을 발생시킨다.The AC input voltage input to the power input unit 1 is a bridge rectifying unit composed of diodes D13, D14, D15, and D16 via an AC input current control unit 2 composed of a capacitor C20 and a resistor R30. In (3), a low voltage pulse voltage is generated.
브릿지 정류부의 맥류전압은 제1 내지 제3 릴레이(Relay) (Re1,Re2,Re3), 저항(R31,R32) 및 캐패시터(C21)로 구성되는 2차 전지 충전부(4)의 맥류전압 평활 회로로 2차 전지(5)를 충전시킨다.The pulsation voltage of the bridge rectifier is a pulsation voltage smoothing circuit of the secondary battery charging unit 4 including the first to third relays (Re1, Re2, Re3), resistors R31, R32, and capacitors C21. The secondary battery 5 is charged.
이와 같은, 저전류 충전회로는 2차 전지의 과충전을 유발하지 않아 전지의 수명에는 큰 영향을 주지 않고 있다.Such a low current charging circuit does not cause overcharging of the secondary battery and does not significantly affect the life of the battery.
그런데, 어느 순간에 정전등으로 A.C 입력전원이 입력되지 않게 되면, 릴레이로 구성된 전력 변환부(8)의 제1 내지 제3 릴레이에는 전류가 흐르지 않게 되어, 제1 내지 제3 릴레이 스위치(SW1, SW2, SW3)를 AC전원 공급시(평상시)의 실선 위치에서 AC전원 단전시(비상시)의 점선 위치로 전환시킨다.However, when the AC input power is not input to the power failure lamp at any moment, no current flows to the first to third relays of the power converter 8 constituted of the relay, and thus the first to third relay switches SW1, SW2, SW3) is switched from the solid line position at the time of AC power supply (normal) to the dotted line position at the time of AC power interruption (emergency).
릴레이 스위치(SW1, SW2, SW3)의 전환으로 본 고안의 비상등용 안정기에는 2차 전지(5)의 전압(V1)이 공급되므로 전체 안정기 회로가 동작하게 된다.By switching the relay switches SW1, SW2, SW3, the voltage stabilizer of the secondary battery 5 is supplied to the emergency ballast of the present invention, so that the entire ballast circuit operates.
2차 전지(5)는 저항(R33), 쵸크코일(T5), 캐패시터(C24) 및 트랜지스터(Q7,Q8)로 구성되는 푸시풀 인버터(6)를 동작시켜, 트랜스(T3), 다이오드(D18,D19) 및 캐패시터(C22,C23)로 구성된 전압공진 및 2배압 회로(7)에서 높은 직류전압을 유도한다.The secondary battery 5 operates the push-pull inverter 6 composed of the resistor R33, the choke coil T5, the capacitor C24, and the transistors Q7 and Q8 to operate the transformer T3 and the diode D18. D19) and capacitors C22 and C23 induce a high DC voltage in the voltage resonant and double voltage circuit 7.
전압공진 및 2배압 회로(7)에서 유기된 높은 직류전압은 전력 변환부(8)의 릴레이 스위치(SW1, SW2, SW3)의 전환으로 형광 램프(LAMP)를 점등시킨다.The high DC voltage induced by the voltage resonance and the double back voltage circuit 7 turns on the fluorescent lamp LAMP by switching the relay switches SW1, SW2, SW3 of the power converter 8.
미설명 부호 8a는 설치시 인위적으로 전원을 차단하고 설치 후 비상등용 안정기를 작동 상태로 만들 경우에 접속하기 위한 배터리 커넥터이며, 저항 R31 및 R32에 접속된 LED는 비상등용 안정기부의 동작 상태를 나타내게 된다.Unexplained symbol 8a is a battery connector for connecting when the power is artificially cut off during installation and the emergency ballast is put into operation after installation, and the LEDs connected to the resistors R31 and R32 indicate the operation status of the ballast for emergency lighting. do.
도 3에는 이상의 비상등용 안정기의 각 주요부의 파형을 나타내었다. 도 3 (a)는 AC 입력전원부(1)의 전원입력 단자의 AC 입력전압의 파형을, 도 3 (b)는 전력변환부(8)의 릴레이 전압의 파형을, 도 3 (c)는 2차 전지(5)의 충방전 전압의 파형을, 그리고 도 3 (d)는 본 고안의 비상등용 안정기의 온/오프 상태를 나타낸다.3, the waveform of each main part of the above-mentioned emergency light ballast is shown. 3 (a) shows the waveform of the AC input voltage of the power input terminal of the AC input power supply unit 1, Figure 3 (b) shows the waveform of the relay voltage of the power converter 8, Figure 3 (c) is 2 The waveform of the charge / discharge voltage of the secondary battery 5, and Fig. 3 (d) shows the on / off state of the emergency light ballast of the present invention.
AC 입력전압이 공급되고 있는 상태에서는 전력변환부가 '온' 상태이고, 따라서 2차 전지는 충전을 계속하며, 비상등용 안정기는 '오프'상태이다. 그러나, 반대로 AC 입력전압이 정전상태에서는 전력변환부가 '오프' 되고, 따라서 2차 전지는 방전을 시작하며, 비상등용 안정기는 '턴온'되어 비상등용 램프를 점등시키게 된다.When the AC input voltage is being supplied, the power converter is in an 'on' state, and thus the secondary battery continues to charge, and the emergency ballast is in an 'off' state. On the contrary, when the AC input voltage is in a blackout state, the power conversion unit is 'off', and thus the secondary battery starts to discharge, and the emergency light ballast is 'turned on' to turn on the emergency lamp.
이상 본 고안을 첨부도면에 도시된 일 실시예를 참조하여 설명하였으나, 본 고안은 이에 한정되는 것은 아니며, 당업자가 용이하게 생각해 낼 수 있는 범위 내에서 여러 가지 변형이 가능함은 물론이다. 따라서, 본 고안의 한계는 다음의 실용신안등록청구범위에 의해서만 한정되어야 한다.Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, the present invention is not limited thereto, and various modifications are possible within a range easily conceived by those skilled in the art. Therefore, the limitation of the present invention should be limited only by the following utility model registration claims.
이상에서 설명한 바와 같이 본 고안은 저전류를 충전하여 비상등용 형광 램프를 점등시키므로 단순한 회로를 적용하여 비상등용 안정기를 실현시킬 수 있으므로, 경제저이고 안정기 수명도 길게 할 수 있다. 더구나, 전자식 형광등용 안정기 부분에 대해서도 많은 개선이 가하여 졌다.As described above, since the present invention charges a low current to light an emergency lamp fluorescent lamp, it is possible to realize a ballast for emergency lamps by applying a simple circuit, thereby making it economically economical and extending the life of the ballast. In addition, many improvements have been made to the ballast section for electronic fluorescent lamps.
