Description

형광등의 점등장치Lighting device of fluorescent lamp

첨부된 도면은 본 고안을 설명하기 위한 전기적 결선도이다.The accompanying drawings are electrical connection diagrams for explaining the present invention.

본 고안은 형광등의 점등 장치에 관한 것으로 특히 쵸크 코일이 없는 점등장치에 관한 것이다.The present invention relates to a lighting device of a fluorescent lamp, and more particularly to a lighting device without a choke coil.

종래의 형광등 점등장치에 있어서는 전원과 형광등 사이에 쵸크코일을 개입시켜 안정기의 역할을 하도록 함으로 쵸크코일과 이를 구성하는 규소강판으로 되는 철심의 무게가 컸으며 이와같은 철심이 잘못 조합되어 있는 경우 소음발생의 원인이 되었다.In the conventional fluorescent lamp lighting device, the choke coil is placed between the power supply and the fluorescent lamp to act as a stabilizer so that the weight of the iron core made of the choke coil and the silicon steel sheets constituting it is large and noise is generated when such iron cores are incorrectly combined. Caused.

또한 쵸크코일은 자체 소모전력이 크고, 과열되는 등의 폐단이 있어 화재의 염려가 있었다.In addition, the choke coil itself has a high power consumption, and there is a danger of fire due to overheating.

또 쵸크코일을 구성하기 위해서는 많은 일손이 필요하므로 생산 원가의 상승을 초래하여 규정치 이하인 경우 글로우램프나 형광등의 수명을 단축시키는 등 여러가지 결점이 있었다.In addition, since the choke coil requires a lot of work, there are various defects such as an increase in production cost and shortening the life of a glow lamp or a fluorescent lamp when it is below a specified value.

본 고안은 상기한 바와 같은 종래의 형광등의 재결점을 해결하고도 가벼우며, 전력소모가 적고, 과열되는 것을 해소하고, 소음발생의 근원이 없어지도록 브리지 정류회로와 트랜지스터 및 가변저항으로 구성되는 전자회로를 구성함으로써 안전기 역할을 하며 더욱이 가변저항치로 광도를 임의로 조정할 수 있는 매우 우수한 형광등을 얻을 수 있는 것이다.The present invention is lighter to solve the defects of the conventional fluorescent lamps as described above, the power consumption is low, eliminates overheating, and the noise is composed of a bridge rectifier circuit, a transistor and a variable resistor to eliminate the source of noise By constructing a circuit, it acts as a safety device, and it is possible to obtain a very good fluorescent lamp that can arbitrarily adjust the brightness with variable resistance.

본 고안을 첨부된 도면에 따라 상술하면 다음과 같다. 형광등(FL)의 전극(F1, F2)의 일단은 글로우램프(GL)에 연결되어 있음은 공지의 결선과 같다. 그러나 전극(F1)의 타단은 다이오드(D1,D2,D3,D4)로 구성되는 브리지 정류 회로의 출력측일단(+)에 연결되고 또 전극(F2)의 타단은 트랜지스터(TR)의 콜렉터(C)에 연결되고 에미터(E)는 다이오드(D1,D2,D3,D4)로 구성되는 브리지 정류회로의 출력측 타단(-)에 연결되어 있다.When the present invention is described in detail according to the accompanying drawings as follows. One end of the electrodes F 1 and F 2 of the fluorescent lamp FL is connected to the glow lamp GL as in a known connection. However, the other end of the electrode F 1 is connected to the output side end (+) of the bridge rectifier circuit composed of diodes D 1 , D 2 , D 3 , D 4 , and the other end of the electrode F 2 is a transistor TR Is connected to the collector (C) and the emitter (E) is connected to the other end (-) of the bridge rectifier circuit composed of diodes (D 1 , D 2 , D 3 , D 4 ).

또 트랜지스터(TR)의 베이스에는 저항(R)과 가변저항(VR)이 직열 연결되어 있어서 가변저항(VR)의 가변단자가 다이오드(D1,D2,D3,D4)로 구성되는 브리지 정류회로의 축력측일단(+)에 연결시켜서 된 것으로 도면중 미설명부호 SW는 스위치이며, S는 플러그를 표시한다.In addition, since the resistor R and the variable resistor VR are directly connected to the base of the transistor TR, a bridge in which the variable terminals of the variable resistor VR are composed of diodes D 1 , D 2 , D 3 , and D 4 is provided. In this figure, reference numeral SW denotes a switch, and S denotes a plug.

상기한 바와 같은 구성으로 된 본 고안의 작용과 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention having the configuration as described above are as follows.

도면에서 플러그(S)를 콘센트(도시하지 않음)에 꽂고 스위치(SW)를 “ON”시키면 다이오드(D1,D2,D3,D4)로 구성된 브리지정류회로에 의해 플러그(S)를 통해 입전되는 교류 전원은 직류로서 일단(+)과 타단(-)으로 전파정류되어 나타난다. 따라서 브리지정류회로의 출력측인 일단(+)에 연결된 가변저항(VR)의 가변단자와 저항(R)에 의해 트랜지스터(TR)의 베이스에 전류가 가해짐으로써 트랜지스터(TR)는 도통되어 에미터(E)를 콜렉터(C)가 “ON”됨으로써 형광등(FL)의 전극(F1,F2)에는 글로우램프(GL)에 의해 가열되어 전자를 방출함으로써 형광등(FL) 내부에 도포된 형광물질에 전자가 충돌하여 발광하게 된다.In the drawing, when the plug S is plugged into an outlet (not shown) and the switch SW is “ON”, the plug S is connected by a bridge rectifier circuit composed of diodes D 1 , D 2 , D 3 , and D 4 . The AC power input through the DC is a direct current and is rectified by one end (+) and the other end (-). Accordingly, the transistor TR becomes conductive by applying current to the base of the transistor TR by the variable terminal of the variable resistor VR connected to one end (+), which is the output side of the bridge rectifier circuit, and the resistor R. E) is turned on by the collector (C) "ON" to the fluorescent material applied to the inside of the fluorescent lamp (FL) by heating the electrode (F 1 , F 2 ) of the fluorescent lamp (FL) by the glow lamp (GL) to emit electrons The electrons collide and emit light.

그러나 전극(F2)과 전원인 브리지회로의 출력측 사이에 개입된 트랜지스터(TR)의 베이스(B)에 연결되는 가변저항(VR)의 값에 의한 적은 전압치로써 트랜지스터(TR)의 출력측인 콜렉터(C)와 에미터(E)간의 전류치가 정해짐으로 형광등(FL)의 방전에 필요한 전압과 전류를 조정하게 된다.However, the collector, which is the output side of the transistor TR, is a small voltage value due to the value of the variable resistor VR connected to the base B of the transistor TR interposed between the electrode F 2 and the output side of the bridge circuit as the power source. Since the current value between (C) and emitter (E) is determined, the voltage and current required for discharging the fluorescent lamp FL are adjusted.

따라서 본 고안에 있어서는 가변저항(VR)을 변화시킴에 따라 형광등(FL)의 광도가 변화하게 된다.Therefore, in the present invention, as the variable resistance VR is changed, the luminance of the fluorescent lamp FL is changed.

그러므로 가변저항(VR)을 조정하는데 따라 형광등의 광도를 일정하게 할수 있으므로 전압의 기복이 심한 경우 일지라도 일정한 광도를 유지할 수가 있고 또한 광도를 임의로 조정할 수도 있다.Therefore, the brightness of the fluorescent lamp can be made constant by adjusting the variable resistance VR, so that even in the case of severe voltage ups and downs, the constant brightness can be maintained and the brightness can be arbitrarily adjusted.

또한 본 고안에 관련된 형광등의 회로는 트랜지스터(TR)와 저항(R) 및 다이오드(D1,D2,D3,D4)로 구성되므로 무게가 가벼우며 공간을 차지하는 량이 작아서 형광등 자체를 소형화할 수 있어서 실용적이며 저렴하게 생산할 수 있는 것이다.In addition, since the circuit of a fluorescent lamp according to the present invention is composed of a transistor (TR), a resistor (R) and a diode (D 1 , D 2 , D 3 , D 4 ), it is light in weight and occupies a small space, thereby miniaturizing the fluorescent lamp itself. It can be practical and inexpensive to produce.
