Description
제1도는 이 고안의 한 실시예의 전기회로도이다.1 is an electrical circuit diagram of one embodiment of the present invention.
이 고안은 형광등의 점등회로에 관한 것으로서, 좀더 상세히 설명하면, 메인트랜스에 형광등의 음극가열용 트래스와 정지스위치용 브리지회로를 접속 구성케하여 형광등이 점등되면, 정지스위치용 브리지회로에 의하여 음극가열용 트랜스의 통전이 차단되고, 결국 형광등의 음극필라멘트에 전류가 계속적으로 흐르지 않음으로서 절전할 수 있는 형광등의 점등회로에 관한 것이다.The present invention relates to a lighting circuit of a fluorescent lamp, which will be described in more detail.If the fluorescent lamp is turned on by connecting the cathode heating trace of the fluorescent lamp and the bridge circuit for the stop switch to the main transformer, the cathode heating is performed by the stop switch bridge circuit. The present invention relates to a lighting circuit of a fluorescent lamp which can save power by interrupting the energization of the transformer and eventually causing no current to flow through the cathode filament of the fluorescent lamp.
종래의 형광등점등회로는 래피드스타트식 및 전자식점등회로를 막론하고 형광등이 점등된 후에도 음극필라멘트에 계속적으로 전류가 흐르기 때문에 전력이 많이 소비되어 전력의 낭비가 심하며 또 형광등의 수명이 단축되는 문제점이 있었다.Conventional fluorescent lighting circuits have a problem in that a large amount of power is consumed because the current continuously flows through the cathode filament even after the fluorescent lights are turned on, regardless of the rapid start type or electronic lighting circuits, and the life of the fluorescent lamps is shortened. .
이 고안은 상기한 종래의 문제점을 시정하기 위하여 안출된 것으로서 이를 도면에 의하여 설명하면 다음과 같다.This invention has been devised to correct the above-described problems, which will be described below with reference to the accompanying drawings.
제1도는 이 고안의 전기회로도인데 도면 중, T1은 메인트랜스로서, 1차코일(L1) 및 2차코일(L2)을 갖고 있으며 역율개선용컨덴서(C)가 있다. T2는 음극가열용 트랜스인데, 이 트랜스(T2)에는 1차코일(L3) 및 2차코일(L4),(L5)가 권선되어 있으며 이 2차코일(L4) 및 (L5)은 형광등의 음극필라멘트(F1) 및 (F2)를 가열해주는 코일이다.1 is an electric circuit diagram of the present invention, in which T1 is a main transformer, which has a primary coil L1 and a secondary coil L2, and has a power factor improving capacitor C. T2 is a cathode heating transformer, in which the primary coil L3 and the secondary coils L4 and L5 are wound, and the secondary coils L4 and L5 are cathodes of fluorescent lamps. It is a coil that heats the filaments F1 and F2.
그런데, 이 음극가열용트랜스(T2)의 1차코일(L3)의 일단은 메인트랜스(T1)의 컨덴서(C)의 일측과 접속하고 타단은 정지 스위치용 브리지회로(S)의 일측과 접속하였으며 그리고 브리지회로(S)의 에스씨알(SCR)의 게이트에는 보호용저항(R)을 통하여 제너다이오드(ZD)를 접속 연결하였다.However, one end of the primary coil L3 of the cathode heating transformer T2 was connected to one side of the capacitor C of the main transformer T1, and the other end thereof was connected to one side of the bridge circuit S for the stop switch. The zener diode ZD is connected to the gate of the SCR of the bridge circuit S through a protective resistor R.
이와 같이 구성된 이 고안의 한 실시예를 제1도에 의하여 설명한다.One embodiment of this invention configured as described above will be described with reference to FIG.
입력측에서 예컨대 100V 교류전원을 입가하면 메인트랜스(T1)의 2차코일(L2)에는 200V의 전압이 유기되고 동시에 음극가열용트랜스(T2)의 1차코일(L3)에 200V의 전압이 인가되며 또한 정지스위치용브리지회로(S)의 에스씨알(SCR)에 연결된 제너다디오드(ZD)에도 200V의 전압이 인가되므로 에스씨알(SCR)의 게이트가 열려 도통되고 동시에 트랜스(T2)의 2차코일(L4) 및 (L5)에는 소정의 전압이 유기되어 형광등의 음극필라멘트(F1) 및 (F2)를 가열시킴으로서 형광등이 점등하게 된다.For example, when a 100V AC power is input from the input side, a voltage of 200V is induced to the secondary coil L2 of the main transformer T1 and a voltage of 200V is applied to the primary coil L3 of the cathode heating transformer T2. In addition, since a voltage of 200 V is applied to the Zener diode ZD connected to the SCR of the stop switch bridge circuit S, the gate of the SCR is opened to conduct and at the same time, the secondary coil of the transformer T2. Predetermined voltages are induced in L4 and L5 to heat the fluorescent lamps by heating the cathode filaments F1 and F2 of the fluorescent lamp.
이와 같이 형광등이 점등되면 형광등의 내부저항에 의하여 전압강하가 발생하게 되고 이 전압강하에 의하여 제너다이오드(ZD)는 규정전압치(200V) 이하로 하강하게 되므로 에스씨알(SCR)의 게이트는 닫혀져서 결국 음극가열용트랜스(T2)에는 전류가 차단되며 따라서 형광등의 음극필라멘트(F1),(F2)에 형광등 점등시 계속적인 전류가 흐르지 않음으로서 전력을 절약할 수 있으며 형광등의 수명을 길게 할 수 있다.When the fluorescent lamp is turned on, a voltage drop occurs due to the internal resistance of the fluorescent lamp. As a result, the gate of the SCR is closed because the Zener diode (ZD) falls below the specified voltage value (200 V). As a result, the current is cut off in the cathode heating transformer T2, and thus, the continuous current does not flow when the fluorescent lamp is lit in the cathode filaments F1 and F2 of the fluorescent lamp, thereby saving power and extending the life of the fluorescent lamp. .
이상 설명한 것과 같이 이 고안은 메인트랜스(T1)에 음극가열용트랜스(T2)와 정지스위치용 브리지회로(S)를 접속시키고 트랜스(T2)의 2차코일(L4) 및 (L5)을 형광등의 음극필라멘트(F1) 및 (F2)에 연결구성함으로서 형광등의 점등시 음극필라멘트(F1) 및 (F2)에 전류가 계속적으로 흐르지 않게 되므로 전력을 절약할 수 있으며 또 형광등의 수명을 길게 할 수 있는 효과가 있다.As described above, this invention connects the cathode heating transformer (T2) and the stop switch bridge circuit (S) to the main transformer (T1) and replaces the secondary coils (L4) and (L5) of the transformer (T2) with a fluorescent lamp. By connecting to the cathode filaments (F1) and (F2), the current does not flow to the cathode filaments (F1) and (F2) continuously when the fluorescent lamp is turned on, thereby saving power and extending the life of the fluorescent lamp. There is.
