Description

형광등용 전자식 점등관{ELECTRONIC STARTER FOR FLUORESCENT LAMP}Electronic lighting tube for fluorescent lamps {ELECTRONIC STARTER FOR FLUORESCENT LAMP}

본 고안은 형광등용 BIMETAL점등관을 형광등용 전자식 점등관으로 개발한 것으로서 BIMETAL로 구성되어 주위온도, 전압변화등으로 불규칙한 동작을 하는 것을 전자식 회로방식을 개발하여 주위온도, 전압변화에도 무관하게 동작하도록 단점을 보완하여 실용성있게 개발된 제품이다.The present invention was developed as an electronic lighting tube for fluorescent lamps, and it was composed of BIMETAL and developed an electronic circuit method to operate irregularly with ambient temperature and voltage changes. It is a product developed in a practical way.

본 고안은 기존 형광등용 BIMETAL점등관이 주위온도, 전압변화등으로 불규칙한 동작에 의한 불규칙한 점등을 하던 것을 전자식으로 개발하였으며,주위 온도나 전압변화에도 무관하게 동작하도록 단점을 보완하였으며, 형광구 모양 (직관, 원형, PL등 )에도 상관없이 일발점등되도록 고안된 전자식 점등관이다.The present invention was developed electronically that the conventional BIMETAL lighting tube for fluorescent lamps was irregularly lit by irregular operation due to ambient temperature and voltage change, and it compensated for the disadvantages to operate regardless of the ambient temperature or voltage change. , Circular, PL, etc.) It is an electronic lighting tube designed to turn on one light regardless of).

기존의 BIMETAL점등관은 특히 주위온도나 인가전압의 변동 및 점등관의 기계적 특성 편차로 인하여 예열시간이 불규칙하고 접점작동이 수회 불규칙하게 일어나기 때문에 형광램프의 최적 방전개시를 기대할 수 없고 램프의 조기 흑화현상 및 조기단선을 초래하기도 한다. 또한 점등시 수회 불규칙 점등으로 강력한 전기노이즈을 발생시키고 안정기의 절연특성열화, 램프의 수명말기시 계속적인 점등반복으로 과도한 전력소모를 유발시켜 점등관자체의 수명단축은 물론 접점융착이 될 경우에는 안정기를 가열시켜 화재의 위험까지 초래 할 수 있다. 이런 단점을 보완하여 개발한 제품이 전자식 점등관이다.Existing BIMETAL lamps have irregular preheating times and irregular contact operation several times due to fluctuations in ambient temperature, applied voltage and mechanical characteristics of the lamp tube. Therefore, it is impossible to expect the optimum discharge of fluorescent lamps. It can also lead to premature breaks. In addition, it generates strong electric noise by irregular lighting several times during lighting, deteriorates the insulation characteristics of the ballast, and causes excessive power consumption due to continuous lighting repetition at the end of lamp life. This may cause fire hazard. The product developed by supplementing these shortcomings is an electronic lighting tube.

본 고안은 온도휴즈, 구동회로의 보완회로 및 전파정류회로와 전압분배 및 적분, 온도감지회로로 펄스를 발생하여 구동회로를 구동하도록 고안되어 있다. 형광등용 전자식 점등관은 전원 ON시 온도휴즈를 통해 전파정류회로에서 DC화한 전압을 분배, 적분회로 및 온도감지회로에 의해 전압이 적분되면 이 적분된 전압을 이용, 펄스화하여 구동회로를 ON/OFF 동작되도록 하여 형광구의 HEATER를 예열한다. 이때 구동회로 ON/OFF 동작을 구동회로의 보완회로에서 형광램프에 필요한 고전압이 발생되도록 도와준다.The present invention is designed to drive a driving circuit by generating pulses with a temperature fuse, a complementary circuit of a driving circuit, a full-wave rectifier circuit, a voltage distribution and integration, and a temperature sensing circuit. Electronic lamp tube for fluorescent lamp distributes DC voltage in full-wave rectification circuit through temperature fuse when power is on, and when voltage is integrated by integrating circuit and temperature sensing circuit, it uses this integrated voltage to pulse and drive driving circuit. Preheat the heater of the fluorescent bulb by operating. At this time, the driving circuit ON / OFF operation helps to generate the high voltage required for the fluorescent lamp in the complementary circuit of the driving circuit.

점등된 상태에서는 전자식 점등관 양단에 전압이 강하되어 더 이상 동작을 하지 않도록 고안되었으며, 만약 형광구 말기에 이상현상이 발생시는 온도감지회로에서 인지하여 구동회로 동작을 차단하여 전자식 점등관 동작을 멈춘다. 마그네틱안정기 및 본 전자식 점등관의 이상 발생시에는 온도휴즈가 동작하여 과열 및 화재발생을 방지한다.In the lit state, the voltage is dropped on both ends of the electronic lighting tube so that it does not operate any more. If an abnormal phenomenon occurs at the end of the fluorescent bulb, the temperature sensing circuit recognizes and stops the driving circuit operation to stop the electronic lighting tube operation. In case of abnormality of magnetic ballast and electronic lighting tube, temperature fuse operates to prevent overheating and fire.

형광등의 점등회로에 있어서 기존의 바이메탈식 스타트의 위치에 도1에 의하여 본 고안의 구성 및 효과를 설명하고자 합니다.In the lighting circuit of a fluorescent lamp, the configuration and effect of the present invention will be described with reference to FIG. 1 at the position of an existing bimetallic start.

형광등의 전극과 직렬로 온도FUSE(1) 와 브리지 다이오드(3)를 직렬로 접속하되 브리지 다이오드(3) 의 + 측사이에는 저항을 통해서 연결한다. 브리지 다이오드(3) 의 + 측과 - 측사이에는 제너다이오드(4)와 분압저항(4) 및 충전용 콘덴서(4)를 직렬로 연결하고 충전용 콘덴서와 병렬로 써미스타 NTC(4)를 연결하며 점등되기 전에는 형광등 양단에 전원전압이 모두 걸려서 브리지 다이오드(3) 양단에 전원전압의 최고치가 모두 걸리게 되어 제너다이오드(4) 의 전압 이상으로 인가되면 분압저항(4)를 통하여 충전용 콘덴서(4) 에 충전되고 시간이 흐름에 따라 충전용 콘덴서(4) 의 양단전압이 다이악의 트리거 전압 이상으로 되면 다이악을 통하여 트리거 펄스를 발생시켜 구동회로(5) 의 트랜지스타의 베이스에 연결되어 구동회로(5) 의 트란지스타가 동작하여 도통되며 브리지 다이오드(3) 양단이 도통하여 회로 전체가 도통되므로 형광등에 전도가 형성되고 형광등 필라멘트가 가열되면서 브리지 다이오드(3) 양단의 전압이 트랜지스타의 동작상태를 유지시키는 전압이하로 떨어지면서 구동회로(5) 의 동작을 멈추게 되면 형광등 안정기에서 역기전력이 발생되어 구동회로의 보안회로(2) THYRISTOR가 순간 도통하여 형광구의 필라멘트에 고전압이 발생되어 형광등이 점등된다.The temperature FUSE (1) and the bridge diode (3) are connected in series with the fluorescent lamp electrode, but are connected between the + side of the bridge diode (3) through a resistor. Connect the zener diode (4), the voltage divider (4) and the charging capacitor (4) in series, and connect the thermistor NTC (4) in parallel with the charging capacitor between the + and-sides of the bridge diode (3). Before the lamp is turned on, the power supply voltage is applied to both ends of the fluorescent lamp, and the maximum value of the power supply voltage is applied to both ends of the bridge diode 3. When the voltage is applied above the voltage of the zener diode 4, the charging capacitor 4 ) And when the voltage across the charging capacitor 4 becomes more than the trigger voltage of the diaak as time passes, it generates a trigger pulse through the diaak and is connected to the base of the transistor star of the driving circuit 5 to drive circuit The transistor star of (5) is conducting and conducting. The bridge diode (3) conducts and the entire circuit is conducting, so conduction is formed in the fluorescent lamp and the fluorescent filament is heated. (3) When the voltage at both ends drops below the voltage to maintain the operation state of the transistor star and stops the operation of the driving circuit 5, the counter electromotive force is generated from the fluorescent lamp ballast, and the security circuit of the driving circuit (2) High voltage is generated in the filament of the fluorescent bulb, the fluorescent lamp is turned on.

형광등이 점등되면 브리지 다이오드(3) 의 양단전압은 점등되기전 전압의 약 1/2 정도로 강화되어 회로 동작을 멈춘다.When the fluorescent lamp is turned on, the voltage at both ends of the bridge diode 3 is strengthened to about 1/2 of the voltage before it is turned on to stop the circuit operation.

상술한 내용은 형광구 말기까지 진행되다 형광구 말기에는 전원전압이 브리지 다이오드(3) 양단에 모두 걸리게 되어 구동회로(5) 의 트랜지스타가 동작상태가 되어 열을 발생하게 되는데 충전용 콘덴서(4) 와 병렬로 연결된 써미스타 NTC(4) 가 열을 인지하여 구동회로(5) 의 트랜지스타 동작을 멈추게 하여 내부온도가 85도 이상 오르지 못하도록 제어한다. 만약, 형광등의 안정기 및 본 고안된 회로에 고전압, 과전류, 낙뢰등 문제가 발생시에는 온도FUSE (1) ( 150도 이상 온도 발생 시 FUSE가 단락됨 ) 가 동작하여 부품의 연소로 인한 화재를 예방하도록 고안된 형광등용 전자식 점등장치이다.The above description proceeds to the end of the fluorescent bulb. At the end of the fluorescent bulb, the power supply voltage is applied to both ends of the bridge diode 3 so that the transistor star of the driving circuit 5 is operated to generate heat. ) Thermistor NTC (4) connected in parallel with the control unit senses the heat and stops the transistor star operation of the driving circuit (5) so that the internal temperature does not rise above 85 degrees. In case of high voltage, over current, lightning, etc. problem in the ballast of fluorescent lamp and the designed circuit, the temperature FUSE (1) (FUSE is short-circuited when the temperature is over 150 degrees) is operated to prevent fire due to the combustion of parts. Electronic lighting device for fluorescent lamps.

본 고안된 형광등용 전자식 점등관은 점등시 형광램프의 깜박꺼림없이 일발점등되므로 초기 전력소모의 낭비를 줄였으며 형광구의 흑화현상도 지연되어 나타나므로 형광구 수명 연장 효과가 크다. 또한 고전압, 과전류에 의한 부품의 연소로 인한 화재예방효과가 있다.The designed electronic lighting tube for fluorescent lamps has a one-time lighting without flickering of fluorescent lamps when it is turned on, which reduces the initial power consumption and delays blackening of fluorescent bulbs. In addition, there is a fire prevention effect due to the combustion of parts by high voltage, overcurrent.
