본 발명은 AC 전원을 이용한 다수의 크세논 램프 동시 점등 장치에 관한 것으로 더욱 구체적으로는 동일한 전원선을 통해 전원을 공급받도록 설치된 다수의 크세논 램프가 동시에 섬광을 발광할 수 있도록 하여 섬광 효과를 증대시킬 수 있게 한 AC 전원을 이용한 다수의 크세논 램프 동시 점등 장치에 관한 것이다.The present invention relates to a device for simultaneously lighting a plurality of xenon lamps using AC power, and more particularly, to allow a plurality of xenon lamps installed to receive power through the same power line to simultaneously emit flashes, thereby increasing the flashing effect. The present invention relates to a plurality of xenon lamp simultaneous lighting devices using an AC power source.

크세논 램프란 석영관 속에 크세논 가스를 봉입하여 램프 속에서 일어나는 방전에 의해 발광이 이루어지도록 한 램프로서, 각종의 광원(光源) 중에서 자연광에 가장 가까운 빛을 내기 때문에, 카메라의 촬영용 스트로보광원, 자동차의 전조등, 실내 조명, 영사기, 영화촬영용 광원 등 다양한 분야에 걸쳐서 널리 사용되고 있는 실정이다.A xenon lamp is a lamp in which a xenon gas is enclosed in a quartz tube so that light is emitted by discharge generated in the lamp. The xenon lamp emits light closest to natural light among various light sources, so that a strobe light source for a camera is used. It is widely used in various fields such as headlights, indoor lighting, projectors, and light sources for filming.

첨부도면 도 1은 일반적인 크세논 램프를 AC 전원으로 사용하기 위한 점등 회로를 나타낸 회로도로서, 도면과 같이 크세논 램프는 전극 A, B 사이에 고압이 인가되어 있는 상태에서 트리거용 전극 Tr에 고압의 impulse전압이 인가되면, 그 순간에 크세논 램프의 전극 A, B가 통전되면서 램프가 섬광을 발하게 되는 것이다.1 is a circuit diagram showing a lighting circuit for using a general xenon lamp as an AC power source. As shown in the drawing, a xenon lamp has a high voltage impulse voltage on a trigger electrode Tr in a state where a high voltage is applied between electrodes A and B. When this is applied, the lamp flashes while the electrodes A and B of the xenon lamp are energized at that moment.

그런데 점등 회로에 다수의 크세논 램프를 설치하여 설치된 다수의 크세논 램프를 동시에 점등하기 위해서는 각각의 크세논 램프에 트리거 전압이 동시에 발생하여야 하는데, 각각의 크세논 램프는 자체 트리거 전압 발생 회로를 내장하고 있어서, 이 트리거 신호의 발생 시기를 각각의 크세논 램프에서 동기 시키는 것이 불가능하여 다수의 크세논 램프를 동시에 점등시키기가 어려운 문제점이 있었다.However, in order to simultaneously light a plurality of xenon lamps installed by installing a plurality of xenon lamps in a lighting circuit, a trigger voltage must be simultaneously generated in each xenon lamp. Each xenon lamp has its own trigger voltage generation circuit. Since it is impossible to synchronize the generation timing of the trigger signal in each xenon lamp, it is difficult to simultaneously light a plurality of xenon lamps.

본 발명은 위와 같은 종래의 문제점을 해소하기 위하여 개발한 것으로서, 본 발명의 목적은 동일 전원을 공급받는 서로 다른 거리에 설치된 다수의 크세논 램프를 동시에 점등시킬 수 있도록 하는 데 있다.The present invention has been developed to solve the above-mentioned conventional problems, and an object of the present invention is to be able to light a plurality of xenon lamps installed at different distances at the same power supply.

이러한 목적 달성을 위하여 본 발명은 전원선에 컨트롤러를 장착해 두고, 여기서 트리거 신호를 발생시켜, 이 트리거 신호를 전원선에 중첩하여 크세논 램프로 전달하면, 크세논 램프에서는 AC전원선을 통해 전원과 같이 전달되는 트리거 신호를 분리하여 램프의 섬광발생신호로 사용함으로써, 동일 회로에 연결 설치된 다수의 크세논 램프를 동시에 점등시킬 수 있게 한 구성이다.In order to achieve the above object, the present invention is equipped with a controller in the power supply line, and generates a trigger signal, and the trigger signal is superimposed on the power supply line and transmitted to the xenon lamp. By separating the trigger signal to be used as a flashing signal of the lamp, it is a configuration that can be turned on at the same time multiple xenon lamps connected to the same circuit.

AC전원공급부(10)로 부터 공급된 전원을 크세논 램프(30)에 공급하는 AC전원선(20)과, An AC power supply line 20 for supplying power supplied from the AC power supply unit 10 to the xenon lamp 30;

상기 AC전원선(20)에 설치되어 트리거 신호를 생성한 후, AC전원선(20)을 통해 크세논 램프(30)로 전달하는 컨트롤러(40)와,A controller 40 installed on the AC power line 20 to generate a trigger signal, and transmitting the trigger signal to the xenon lamp 30 through the AC power line 20;

상기 트리거 신호가 중첩된 전원을 공급받아 중첩된 신호에서 트리거 신호를 분리한 후, 분리된 트리거 신호에 의해 점등이 이루어지는 크세논 램프(30)로 이루 어진 구성이다.After the trigger signal is supplied with the overlapped power, the trigger signal is separated from the superimposed signal, and the Xenon lamp 30 is turned on by the separated trigger signal.

한편, 상기 컨트롤러(40)는 트리거 신호용 impulse발생회로와, 상기 impulse를 AC전원선(20)상에 중첩시켜 보내기 위한 트랜스(T1)로 구성되는데, impulse발생회로는 캐패시터(C)와 다이오드(R) 및 저항(R)으로 구성된다.On the other hand, the controller 40 is composed of a trigger signal impulse generating circuit and a transformer (T1) for sending the impulse superimposed on the AC power line 20, the impulse generating circuit is a capacitor (C) and a diode (R) ) And a resistor (R).

또한, 상기 크세논 램프(30)는 AC전원에 중첩되어 전달되는 impulse 전압을 통해 트리거 신호 전압을 생성하는 트랜스(T2)를 포함한다.In addition, the xenon lamp 30 includes a transformer T2 for generating a trigger signal voltage through an impulse voltage transmitted by being superimposed on an AC power source.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면에 의하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

첨부도면 도 2는 본 발명의 크세논 램프(30) 점등 회로를 나타낸 것으로서, 도면과 같이 본 발명의 회로는 AC전원과 전원공급선, 그리고 컨트롤러(40)와 크세논 램프(30)로 구성된다.2 shows a xenon lamp 30 lighting circuit of the present invention. As shown in the drawing, the circuit of the present invention is composed of an AC power supply and a power supply line, and a controller 40 and a xenon lamp 30.

그 중 컨트롤러(40)는 캐패시터(C)와 다이오드(R) 및 저항(R)으로 구성된 트리거 신호용 impulse발생회로를 구성하게 되는데, 도면과 같이 AC전원부를 통해 AC전원이 공급되면, AC전원선(20)에 설치된 컨트롤러(40)의 impulse발생회로의 캐패시터(C)에는 다이오드(R)와 저항(R)을 통해 직류 전압이 충전된다.Among them, the controller 40 constitutes an impulse generating circuit for a trigger signal consisting of a capacitor C, a diode R, and a resistor R. When the AC power is supplied through the AC power unit as shown in the drawing, the AC power line ( The capacitor C of the impulse generating circuit of the controller 40 installed in the controller 20 is charged with a DC voltage through the diode R and the resistor R.

이때, 스위치(SW)를 ON시키면 캐패시터(C)에 충전되어 있던 전하는 갑작스럽게 코일(L2)를 통해 방전되면서, 코일(L2)에는 날카로운 impulse 전류가 흐르고, 이 impulse 는 트랜스(T1)를 통해 유기되어 AC전원선(20)에 중첩된다.At this time, when the switch (SW) is turned on, the charge charged in the capacitor (C) is suddenly discharged through the coil (L2), a sharp impulse current flows through the coil (L2), this impulse is induced through the transformer (T1) And overlaps with the AC power supply line 20.

그리하여 첨부도면 도 3과 같이 AC전원 전압에 날카로운 파형의 impulse 신호가 겹쳐지면서, 크세논 램프(30)로 전달되는 것이다.Thus, as shown in FIG. 3, the impulse signal having a sharp waveform overlaps with the AC power supply voltage, and is transmitted to the xenon lamp 30.

이렇게 AC전원 전압에 날카로운 파형의 impulse 신호가 중첩된 채 크세논 램프(30)로 AC전원이 공급되면, 크세논 램프(30)는 AC전원선(20)에서 공급되는 AC전원을 받아들일 뿐만 아니라, AC전원에 중첩되어 전달되는 impulse 전압을 트랜스(T2)를 이용해 코일(L3)에 유기되도록 하고, 이 전압은 다시 코일(L4)에 유기되어 트리거 신호 전압으로 생성됨으로써, 이 전압이 크세논 램프(30)의 트리거 전극에 인가되어 크세논 램프(30)를 점등시킬 수 있게 되는 것이다.When AC power is supplied to the xenon lamp 30 while the impulse signal having a sharp waveform overlaps with the AC power voltage, the xenon lamp 30 not only receives AC power supplied from the AC power line 20, but also AC The impulse voltage superimposed on the power source is induced in the coil L3 using the transformer T2, and this voltage is again induced in the coil L4 and generated as a trigger signal voltage, whereby this voltage is the xenon lamp 30. It is applied to the trigger electrode of the xenon lamp 30 will be able to light up.

따라서, 첨부도면 도 4와 같이 동일한 AC전원선(20)을 이용해 전원을 공급받는 다수의 크세논 램프(30)를 설치하더라도, AC전원이 컨트롤러(40)를 통과한 후, 다수의 크세논 램프(30)로 전달되게 하면, 동일한 AC전원선(20)에 다수의 크세논 램프(30)가 연결되어 있더라도 각각의 크세논 램프(30)를 동시에 점등시켜 섬광을 발광시킬 수 있게 되는 것이다.Therefore, even if a plurality of xenon lamps 30 are supplied using the same AC power line 20 as shown in FIG. 4, after the AC power passes through the controller 40, the plurality of xenon lamps 30 In this case, even if a plurality of xenon lamps 30 are connected to the same AC power line 20, each of the xenon lamps 30 can be turned on at the same time to emit flashes.

한편, 본 발명은 2가닥의 AC전원선(20) 외에 별도의 트리거 신호를 전달하기 위한 부가 장치나 전송선 등이 필요치 않으므로 다수의 크세논 램프(30)를 점등시키기 위한 장치의 구성을 매우 간소하게 구성할 수 있는 이점이 있다.On the other hand, since the present invention does not require an additional device or a transmission line for transmitting a separate trigger signal in addition to the two AC power lines 20, the configuration of a device for turning on a large number of xenon lamps 30 is very simple. There is an advantage to this.

또한, 본 발명에서 트랜스(T1, T2)는 페라이트 코어에 코일이 극히 적은 권선수로 감겨 있기 때문에 인덕턴스가 매우 낮아 통상의 60㎐인 AC전원이 흐르는 데 아무런 지장을 주지 않음을 미리 밝혀둔다.In addition, in the present invention, since the transformers T1 and T2 are wound around the ferrite core with a very small number of windings, the inductance is very low, so that it does not interfere with the flow of AC power having a normal 60 Hz.

이상에서 설명한 바와 같이 본 발명은 동일한 AC전원선을 이용해 전원을 공급받는 다수의 크세논 램프가 동시에 점등하여 섬광을 발광할 수 있도록 함으로써 섬광 효과를 증대시킬 수 있기 때문에 크세논 램프의 성능 및 활용성을 향상시킬 수 있는 이점이 있다.As described above, the present invention improves the performance and utility of the xenon lamp because a plurality of xenon lamps, which are powered by the same AC power line, can be turned on at the same time so that the flash light can be increased. There is an advantage to this.
