본 고안은 형광등 순시 점등장치에 관한 것으로, 특히 형광등을 반도체스위치를 이용하여 순시점등되도록 600볼트이상의 고압펄스 발생회로를 구성하도록 한 것이다.The present invention relates to a fluorescent lamp instantaneous lighting device, in particular to configure a high-voltage pulse generating circuit of 600 volts or more so that the fluorescent lamp is instantaneously turned on using a semiconductor switch.
이하, 본 고안을 첨부된 도면에 따라 상술한다.Hereinafter, the present invention will be described in detail according to the accompanying drawings.
교전전압입력단(R)은 안정코일(B1)을 통해 형광등의 필라멘트(F1)에 인가되고, 상기한 필라멘트(F1)는 저항(R1)과 콘덴서(C1) 및 다이오드(D1)과 병렬연결되어 콘덴서(C2)를 통해 펄스트랜스(PT1)의 중간텝에 연결되고 사이닥(SSS1)을 통해서는 펄스트랜스(PT1)의 1차코일(N1)에 연결하였으며 2차코일(N2)은 형광등의 필라멘트(F2)와 연결하여서 안정기코일(B2)을 통해 교류입력단(S)에 연결하여서 된 것이다.The engagement voltage input terminal R is applied to the filament F 1 of the fluorescent lamp through the stabilizer coil B 1 , and the filament F 1 is a resistor R 1 , a capacitor C 1 , and a diode D 1. ) Is connected in parallel to the intermediate step of the pulse transformer (PT 1 ) through the capacitor (C 2 ) and to the primary coil (N 1 ) of the pulse transformer (PT 1 ) through the Sidac (SSS 1 ). The secondary coil N 2 is connected to the AC input terminal S through the ballast coil B 2 by connecting to the filament F 2 of the fluorescent lamp.
도면중 미설명부호 C3는 콘덴서이다.In the figure, reference numeral C 3 is a capacitor.
상기와 같은 구성으로 되는 것이므로 전원입력단자(R.S)사이에 전원 예를들어 220볼트의 교류전원을 인가하는 경우 안정기코일(B1, B2)과 형광등의 필라멘트(F1, F2)를 통해 스타트 회로단자(X1, X2)에 전원이 공급된다. 즉 전원스타트 회로단자(X1, X2)에 전원이 인가되면 단자(X1)와 다이오드(D1) 및 사이닥(SSS1) 펄스트랜스(PT1)의 1, 2차코일(N1, N2)을 통해 단자(X2)에 전원이 공급되나 이때 전압은 사이닥(SSS1)의 턴 -온(브레크오버전압)전압이상이므로 사이닥(SSS1)이 ON되어 전류는 필라멘트(F1)와 단자(X1) 및 다이오드(D1)에 의해 반파정류되어 사이닥(SSS1)과 펄스트랜스(PT1)의 1, 2차코일(N1, N2)을 통해 단자(X2)는 필라멘트(F2)에 전원전압이 1싸이클동안 단자(X1)는 부(-)가 되고 반싸이클동안 제 2a 도와 같이 전류가 흘러 형광등의 필라멘트(F1, F2)를 가열하게 되고, 단자(X1)가 부(-)의 파형일때 콘덴서(C2)는 제 2b 도와 같이 콘덴서의 피크전압디 충전된다.Since it is configured as described above, when applying a power source, for example, 220 volts between the power input terminals (RS), through the ballast coil (B 1 , B 2 ) and the filament (F 1 , F 2 ) of the fluorescent lamp Power is supplied to the start circuit terminals X 1 and X 2 . That is, when power is applied to the power start circuit terminals (X 1 , X 2 ), the primary coils and the secondary coils (N 1 ) of the terminal (X 1 ), the diode (D 1 ) and the sidak (SSS 1 ) pulse transformer (PT 1 ). , N 2), but power is supplied to the terminal (X 2) through the case voltage is between shut (SSS 1 turn) -one (Doc between breather greater because over-voltage) voltage or more (SSS 1) is oN current of the filament Half-wave rectified by (F 1 ) and terminal (X 1 ) and diode (D 1 ) and through the first and second coils (N 1 , N 2 ) of sidak (SSS 1 ) and pulse transformer (PT 1 ). (X 2 ) is the filament (F 2 ) and the terminal voltage (X 1 ) is negative (-) during one cycle of the power supply voltage, and during the half cycle, the current flows like the 2a diagram and the filament (F 1 , F 2 ) of the fluorescent lamp When the terminal X 1 has a negative waveform, the capacitor C 2 is charged to the peak voltage of the capacitor as shown in FIG. 2b.
다시 전원전압의 싸이클이 반전하여 스타트회로단자(X1)가 프러스(+)파형이 되면 다이오드(D1)에 의해 반파정류된 전원은 반전되므로 다이오드(D1)는 도통이 되지 않으므로 필라멘트(F1, F2)에도 전원이 불통되어 가열이 정지된다.Again, the cycle is reversed in the power supply voltage start circuit terminals (X 1) is when the Cypress (+) waveform half-wave rectified by a diode (D 1) power is so reverse diode (D 1) is not a conductive filament (F 1 , F 2 ) is also turned off and the heating is stopped.
따라서 이와같이 되면 펄스트랜스(PT1)에 형광등을 방지시켜 점등시킬 수 있는 적어도 600볼트이상의 고전압이 발생하여 형광등을 방전시켜 점등시켜 주게 되는 것이다.Therefore, in this case, a high voltage of at least 600 volts is generated in the pulse transformer PT 1 to prevent the fluorescent lamps from being lit, thereby discharging the fluorescent lamps to light them.
즉, 단자(X1)의 전압이 부(-)파형일때 다이오드(D1)에 의한 반파정류회로에 의해 펄스트랜스(PT1)의 1, 2차 코일(N1, N2)을 통해 직류전류가 흘러 필라멘트(F1, F2)를 가열하고, 단자(X1)의 파형이 프러스(+)파형으로 바뀌게 되면 반파정류회로의 동작이 정지되므로 직류전류가 차단되고 이에 따라 펄스트랜스(PT1)에는 역기 전압이 발생되며 이와같은 역기전압의 크기는 펄스트랜스(PT1)의 1, 2차 코일(N1, N2)간의 권선미에 따라 제 2d 도와 같은 파형의 고전압이 발생하여 형광등을 점등하게 되는 것으로, 이때 직류전류가 차단되어 역기 전압이 발생할때 콘덴서(C2)에 충전되었던 전압도 펄스트랜스(PT1)의 2차 코일(N2)과 방전회로의 콘덴서(C1) 및 저항(R1)을 통해 방전되므로 펄스트랜스(PT1)에서의 역기전압과 중첩되어 1500볼트정도의 고전압과 전류가 발생되어 형광등을 점등시켜 주게 되는 것이다.That is, when the voltage of the terminal (X 1 ) is a negative waveform, direct current through the primary and secondary coils (N 1 , N 2 ) of the pulse transformer (PT 1 ) by the half-wave rectifier circuit by the diode (D 1 ) When the current flows to heat the filament (F 1 , F 2 ) and when the waveform of the terminal (X 1 ) is changed to the prus (+) waveform, the half-wave rectifier circuit is stopped, so the DC current is cut off and the pulse transformer (PT) 1 ) A counter voltage is generated. The magnitude of the counter voltage is generated by the high voltage of the waveform of 2d degree according to the winding winding between the primary and secondary coils (N 1 , N 2 ) of the pulse transformer (PT 1 ). In this case, when the DC current is cut off and the counter voltage occurs, the voltage charged in the capacitor C 2 is also reduced by the secondary coil N 2 of the pulse transformer PT 1 and the capacitor C 1 of the discharge circuit. As it discharges through the resistor R 1 , it overlaps with the counter voltage in the pulse transformer PT 1 and The current is generated to light the fluorescent lamp.
그러나 만약 1싸이클내에 형광등이 점등되지 않는 경우 다시 수싸이클동안 상기와 같은 동작이 반복되어 형광등을 점등시키게 되므로 순시적으로 점등이 가능하다.However, if the fluorescent lamp is not turned on within one cycle, the above operation is repeated for several cycles, so that the fluorescent lamp is turned on.
도면에서 저항(R1)과 콘덴서(C1)로 되는 방전회로는 콘덴서(C2)의 방전회로소자를 구성하는 것이며, 또 콘덴서(C2)의 방전시 다이오드(D1)를 보호하는 역할을 겸하게 되는 것이다.In the drawing the discharge circuit in which a resistance (R 1) and a capacitor (C 1) is to configure the discharge circuit element of the capacitor (C 2), also serves to protect the discharged when the diode (D 1) of the capacitor (C 2) It will also be.
또, 상기와 같이 형광등이 방전되면 형광등의 과전압이 강하되어 사이닥(SSS1)의 턴 -온전압이하가 되어 사이닥(SSS1)이 OFF되어 전자스타트회로는 차단되어 형광등의 점등에는 아무런 영향을 미치지 아니한다.In addition, when the fluorescent lamp is discharged as described above, the voltage of the fluorescent lamp is between shut (SSS 1) turns of the drop-between is the on-voltage or less shut (SSS 1) is OFF and the electronic-start circuit is cut off light of the fluorescent lamp has no effect Shall not affect.
상기와 같은 본고안은 싸이클이 변화는데 따라 순시적으로 점등될 뿐아니라 회로가 간단하여 경제적이고 실용적인 고안인 것이다.As described above, the present proposal is not only turned on instantaneously as the cycle changes, but also the circuit is simple and economical and practical.
