Description
첨부도면은 본 고안의 회로도.The accompanying drawings are circuit diagrams of the present invention.
본 고안은 통상의 형광등에 있어서 형광등 양측 필라멘트간에 직렬로 부설되어 있는 스타트램프를 콘덴서로 대치하여서된 형광등의 순간 점등장치에 관한 것이다.The present invention relates to an instantaneous lighting device of a fluorescent lamp by replacing a start lamp placed in series between two filaments of a fluorescent lamp with a capacitor in a normal fluorescent lamp.
종래에는 바이메탈을 이용한 스타트램프를 사용하거나 별도의 전원스위치를 부설하여 점등하는 형광등을 사용하여 왔으나, 이는 점등시 예열에 소요되는 전력소비가 많았으며 점등시간이 지연되는 결함이 있었고, 그 구조가 복잡하여 고가이어서 일반에 보급이 부진하였을뿐 아니라 형광등의 고장원인은 주로 스타트램프의 고장과 예열필라멘트의 노화로 사용상 불편하고 경제적 손실이 많은 등의 결함이 있었다.Conventionally, fluorescent lamps using a bimetal start lamp or a separate power switch have been used, but this requires a lot of power consumption for preheating and has a defect in delaying the lighting time, and its structure is complicated. Due to its high price, it was not widely distributed to the general public, and the cause of the failure of the fluorescent lamp was a defect such as a failure of the start lamp and aging of the preheating filament, which resulted in inconvenience and economic loss.
본 고안은 종래의 이와같은 결함을 해소하기 위하여 순간적으로 형광등을 점등케하므로서 형광등의 수명을 연장하고 막대한 기동전력을 절감하게 하는 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is described in detail by the accompanying drawings as to extend the life of the fluorescent lamp and to save enormous starting power by turning on the fluorescent lamp instantaneously to solve such a conventional defect.
즉, 형광등(1)의 필라멘트(2a)와 (2b)에 각각 쵸크코일(3)과 입력전원을 직렬로 연결한 공지회로에 있어서 형광등(1)의 필라멘트(2a')와 (2b') 사이에 직렬로 콘덴서(4)를 연결하여서 된 것이다.That is, in the known circuit in which the choke coil 3 and the input power are connected in series to the filaments 2a and 2b of the fluorescent lamp 1, respectively, between the filaments 2a 'and 2b' of the fluorescent lamp 1 This is done by connecting the condenser 4 in series.
이와같이 구성된 본 고안에 있어서 본 회로구성은 인덕탄스＋레지스탄스＋캬파시탄스＋레지스탄스로 구성된 직렬 공진회로로서 형광등의 순간 점등장치가 구성되는데 쵸크코일(3)의 입력단자와 필라멘트(2b)에 교류전원을 가하면 형광등(1)의 필라멘트(2a)와 (2b)간에는 방전이 시작되지 아니한 상태이므로, 교류전원은 쵸크코일(3)을 경유 필라멘트(2a)(2a')를 통하여 콘덴서(4)를 경과 필라멘트(2b')(2b)로 유통되게 되어 콘덴서(4)에는 충분한 전압이 부가되어 충방전이 시작되고, 필라멘트(2a)(2b)에 예열에 필요한 전류가 유통되면서 공진을 시작하여 콘덴서(4)의 양단에 고조파가 발생하므로 필라멘트(2a)와 (2b)간에 방전이 유기되어 형광등(1)은 순간적으로 점등되며, 방전이 시작되면 필라멘트(2a)와 (2b)에 병열상태가 된 콘덴서(4)의 부가전압이 감소하여 극히 미량의 전류만이 유통하면서 공진을 계속하게 되므로 교류전원전압이 불안정하거나 저하하여도 안정된 방전을 지속할 수 있게 되며 동시에 콘덴서(4)는 라듸오잡음 흡수하는 역할도 겸하게 되는 것이다.In the present invention configured as described above, the circuit structure is a series resonant circuit composed of inductance + resistance + capacitives + resistance, and constitutes a momentary lighting device of a fluorescent lamp. When the AC power is applied to the capacitor, since the discharge is not started between the filaments 2a and 2b of the fluorescent lamp 1, the AC power supply is passed through the choke coil 3 through the filaments 2a and 2a '. ) Is passed through the filament (2b ') (2b) and sufficient voltage is applied to the condenser (4) to start charging and discharging, and the resonance is started while the current required for preheating flows to the filament (2a) (2b) Since harmonics are generated at both ends of the condenser 4, discharge is induced between the filaments 2a and 2b so that the fluorescent lamp 1 is turned on momentarily, and when the discharge starts, the parallel state of the filaments 2a and 2b is established. Voltage of the condenser 4 is reduced and extremely Resonance continues while only a small amount of current flows, so that stable discharge can be maintained even when the AC power supply voltage is unstable or lowered, and at the same time, the capacitor 4 also serves to absorb noise.
이때 콘덴서(4)의 용량은 형광등(1)의 용량에 적합한 공진 용량의 것을 사용하기 때문에 순간 점등을 용이하게 한다.At this time, since the capacitor 4 has a resonance capacitor suitable for the fluorescent lamp 1, the instantaneous lighting is facilitated.
이와같이 본 고안은 스타트램프 대신에 콘덴서를 형광등의 필라멘트에 직열로 연결시키는 지극히 간단한 방법으로서 순간점등을 용이하게 할 뿐 아니라 가격이 매우 저렴하며 기동소비전력을 점감케할 뿐 아니라 라듸오 잡음도 흡수할 수 있는 유용한 고안인 것이다.As such, the present invention is an extremely simple method of connecting a capacitor directly to a filament of a fluorescent lamp instead of a start lamp, which not only facilitates instant lighting but also is very inexpensive, reduces power consumption, and absorbs radio noise. It is a useful design.
