Abstract

PURPOSE: A stabilizer protection device for discharge lamp is provided to prevent a damage of an electronic stabilizer due to a sudden voltage by sensing a current flowing in an output transformer to cut off an AC(alternative current) circuit in an input side of a stabilizer with a relay operation. CONSTITUTION: An operation junction point(1) of a relay(Ry) is connected with one side of an exciting coil(4). A fixing junction point(3) of the relay(Ry) is connected with a minus output part of a bridge diode(5) and the exciting coil(4) of the relay(Ry) is connected with a plus output part of the bridge diode(5). A Zener diode(10) becomes turn-on state by a voltage rise of a sensing coil(14). The Zener diode(10) senses an instant high current generated on both sides of a lamp in case the lamp doesn't be turned on, and excites the relay(Ry) to cut off a supply power.

이하 본 발명을 첨부된 실시예의 회로도에 의거 상술하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the circuit diagram of the attached embodiment.

즉 교류전원(L1)이 공지의 안정기 회로(16)의 입력일측에 연결되고 교류전원(L2)는 릴레이(Ry)고정접점(2)에 연결되었으며 릴레이 고정접점(2)는 릴레이 가동접점(1)과 접속되어 있으므로 릴레이 접점(1)을 통하여 공지의 안정기(16) 입력일측에 연결되어 전원이 안정기에 공급되어 안정기(16)의 출력측 출력트랜스(13)을 통하여 방전램프(15)에 연결되어 점등 하도록 되는 것에 있어서 교류전원(L1, L2)는 콘덴서(6,7)에 연결되어 브릿지 다이오드(5)를 통해 정류되고 전해 콘덴서(11)에 의해 평활화되어 릴레이 여자코일(4)의 전원으로 공급된다. 이때 콘덴서(6,7)은 릴레이 동작후 보지전류만 흐로도록 하고 안정기의 역전류를 방지하기 위한것이며,상기한 브릿지다이오드(5)의 (-)출력단은 릴레이(Ry)의 고정접점(3)에 그리고 (+)출력단은 릴레이(Ry)의 여자코일(4)의 일측에 연결되고 여자코일(4) 다른 일측은 릴레이(Ry)가동접점(1)에 연결되어 릴레이(Ry)여자코일(4)에 연결된 제너다이오드(10)가 감지코일(14)에 전압이 상승하여 도통되어 릴레이(Ry)여자코일에 전류가 흘러서 릴레이(Ry)가 동작하여 가동접점(1)이 고정접점(2)에서 분리 되어 고정접점(3)으로 접속된다.이렇게되면 브릿지 다이오드(5)의 출력 전류가 릴레이(Ry)여자 코일(4)의 양단에 흐르게 되면서 릴레이 동작을 연속적으로 보지시키게 되며,릴레이(Ry)가동접점(1)이 고정접점(2)와 분리되어 접점(3)에 접속 된 상태가 되면 안정기 회로(16)의 입력 교류전원은 차단된 상태로 유지하게 된다. 다이오드(8,9)는 감지코일(14)에 유기되는 고주파 전압을 정류하는 역할을 하며 전해콘덴서(11)과 저항(12)는 릴레이(Ry)여자코일(4)에 공급되는 직류전원의 평활회로이다.That is, the AC power supply L1 is connected to the input side of the known ballast circuit 16, the AC power supply L2 is connected to the relay Ry fixed contact point 2, and the relay fixed contact point 2 is connected to the relay movable contact point 1. Is connected to one side of the ballast (16) input via a relay contact (1), so that power is supplied to the ballast and is connected to the discharge lamp (15) through an output side (13) of the output side of the ballast (16). In order to be lit, the AC power supplies L1 and L2 are connected to the capacitors 6 and 7, rectified through the bridge diode 5, smoothed by the electrolytic capacitor 11, and supplied to the power supply of the relay exciting coil 4. do. At this time, the capacitor (6,7) is intended to flow only the holding current after the relay operation and to prevent the reverse current of the ballast, the negative output terminal of the bridge diode (5) is the fixed contact (3) of the relay (Ry) And the (+) output terminal is connected to one side of the excitation coil (4) of the relay (Ry) and the other side of the excitation coil (4) is connected to the relay (Ry) movable contact (1) relay (R) excitation coil (4) The zener diode 10 connected to) is energized when the voltage rises to the sensing coil 14 so that a current flows through the relay excitation coil so that the relay Ry is operated so that the movable contact 1 is connected to the fixed contact 2. In this case, the output current of the bridge diode 5 flows through both ends of the relay (Ry) excitation coil (4) to continuously hold the relay operation, and the relay (Ry) is activated. When the contact point 1 is separated from the fixed contact point 2 and connected to the contact point 3, the ballast circuit 16 is opened. AC power is to remain blocked. The diodes 8 and 9 serve to rectify the high frequency voltage induced in the sensing coil 14, and the electrolytic capacitor 11 and the resistor 12 smooth the DC power supplied to the relay exciting coil 4. Circuit.

상기와 같은 구성으로 되어 교류전원(L1,L2)가 공지의 안정기회로(16)의 입력측에 인가되면 그 출력측의 출력 트랜스(13)를 통해 방전램프(15)가 점등됨은 공지와 같은 것이므로 이에 대한 설명은 명세서의 간소화를 위해 생략한다.Since the AC lamps L1 and L2 are applied to the input side of the known ballast circuit 16, the discharge lamp 15 is turned on through the output transformer 13 on the output side. The description is omitted for simplicity of the specification.

이와같은 상태에서 방전램프(15)가 예를들어 노후 또는 기타 불량으로 인하여 방전이 제대로 안되어 점등 되지 못하는경우 방전램프(15)는 무부하상태가 되면서 방전램프(15)양단에는 순간적으로 높은전류의 전압이 발생된다. 이와같이 되면,램프에 적합한 전류를 보내도록 설계된 출력트랜스코일(13)에도 높은 전압이 발생하면서 출력트랜스에 같이 감겨져 삽입되어 있는 감지코일(14)에도 순간적으로 유기전압이 급상승하여 다이오드(8,9)를 거쳐 정류되어 역방향으로 연결되어 있는 제너다이오드(10)가 ON되면서 릴레이(Ry)여자코일(4)에 전원이 공급되면서 릴레이(Ry)의 고정접점(2)와 가동접점(1)이 ON 상태에서 OFF 상태로 되고가동접점(1)이 고정접점(3)으로 접속되면서 안정기회로(16)에는 전원이 차단되고 교류 입력측 에는 콘덴서(6,7)을 통해 연결된 브릿지다이오드(5)의 출력 전류가 고정접점(3)을 통해 가동접점(1)로 흐르게 되면서 가동접점(1)과 여자코일(4)한쪽이 연결되어 있으므로 릴레이(Ry)는 계속하여 동작 한다.In this state, when the discharge lamp 15 cannot be turned on due to deterioration or other failures, for example, the discharge lamp 15 is not loaded and the discharge lamp 15 is in a no-load state. Is generated. In this case, a high voltage is generated in the output transcoil 13, which is designed to send a current suitable for the lamp, and the induced voltage rapidly increases even in the sensing coil 14 wound and inserted in the output transformer. The zener diode 10 rectified and connected in the reverse direction is turned on while power is supplied to the relay exciting coil 4, so that the fixed contact point 2 and the movable contact point 1 of the relay Ry are on. Output state of the bridge diode (5) connected via the capacitor (6, 7) to the AC input side as the movable contact (1) is connected to the fixed contact point (3) and the power is cut off from the ballast circuit (16). Is flowed to the movable contact (1) through the fixed contact (3), so that one of the movable contact (1) and the excitation coil (4) is connected, the relay (Ry) continues to operate.

상기와 같이 안정기회로 (16)입력 전원은 안정기외부 교류전원(L1,L2)이 차단 될때까지 연속적으로 차단하여 램프의 이상 상태에서 안정기를 연속 보호할수가 있는것이다.As described above, the input power of the ballast circuit 16 is continuously blocked until the AC power supply L1 and L2 of the ballast are interrupted, thereby protecting the ballast continuously in an abnormal state of the lamp.

상술한 바와 같이 본 발명에 의하면 램프의 불량이나 수명이 다 되어 점등되지 않는 경우 발생되는 돌발 전압으로부터 안정기를 보호할 수 있는 효과가 있는 실용적인 발명인 것이다As described above, the present invention is a practical invention having the effect of protecting the ballast from the sudden voltage generated when the lamp is not turned on due to the failure or life of the lamp.
