본 고안은 주위의 밝고 어두움에 따라 자동 점소등기능을 갖는 리필용 전자식 전구식 형광등기구에 관한 것으로, 조명제어를 위한 전자부품이 내장된 몸체부분과 빛을 발광하는 형광유리관을 분리할 수 있는 구조로 하기위한 방법을 제공하는데 있다.The present invention relates to an electronic light bulb fluorescent lamp for refilling with automatic flashing function according to the ambient light and darkness, and has a structure that can separate the body part containing the electronic parts for lighting control and the fluorescent glass tube emitting light. To provide a way to:
이를 위하여 가) 형광유리관(20)을 끼우거나 뺄 수 있는 구조의 플러그방식 소켓(10)을 몸체(30)중안에 장착하고, 나) 그렇게 하면서도 몸체의 부피가 커지는 것을 억제하기 위하여 기존 전자식 전구식 형광등회로에서 필라멘트(22)를 가열하기위한 부품을 제거하는 대신, 그로우스타터(23)가 내장된 형광램프를 사용하고, 다) 조도센서로 cds를 사용하여 주위가 밝으면 스위칭 트랜지스터(1a)의 베이스전압을 강하시켜 동작을 정지시킴으로써 형광램프가 꺼지고, 어두워지면 다시 트랜지스터의 베이스전압을 정상화시켜 작동이 가능하게 함으로써 형광램프가 켜지도록 하는 단계를 포함한다.To this end, a) A plug-type socket 10 having a structure in which the fluorescent glass tube 20 can be inserted or removed can be mounted in the body 30, and b) the existing electric electric bulb type to suppress the bulkiness of the body while doing so. Instead of removing the components for heating the filament 22 in the fluorescent lamp circuit, use a fluorescent lamp with a built-in glow starter 23, and c) use a cds as an illuminance sensor to brighten the ambient light of the switching transistor 1a. The fluorescent lamp is turned off by dropping the base voltage to stop the operation, and when it is dark, the fluorescent lamp is turned on by normalizing the base voltage of the transistor to enable operation.
상기 구성에 의해 기존회로중 많은 부피를 차지하고 있는 콘덴서와 발열소자인 서미스터를 사용하지 않음에 따라 몸체중앙에 플러그방식의 소켓을 장착하는 것이 가능하고 따라서 수명이 다한 형광유리관만 교체하여 잔존수명이 있는 몸체를 재활용할 수 있으며, 주위의 밝고 어두운 정도에 따라 자동으로 점소등되는 효과가 있다.With the above configuration, it is possible to install a plug-type socket in the center of the body by not using a capacitor and a thermistor which is a large volume of the existing circuit. The body can be recycled and it will automatically turn on and off according to the light and dark surroundings.
Description
본 고안은 명암에 따라 자동으로 점소등되는 기능을 갖는 리필용 전자식 전구식 형광등기구에 관한 것으로써, 보다 상세하게는 수명이 다한 형광유리관만을 교체하여 재사용할 수 있도록, 조명제어를 위한 전자부품이 내장된 몸체(30)의 중앙에 소켓(10)을 장착하여 플러그방식의 형광유리관(20)을 끼우고 뺄 수 있도록 구성하고,주위의 밝고 어두움에 따라 자동으로 꺼지거나 켜지는 기능을 갖는 리필용 전자식 전구식 형광등기구의 구조와 조명제어회로에 관한 것이다.The present invention relates to an electronic bulb type fluorescent lamp for refill having a function of automatically turning on and off according to contrast, and more specifically, an electronic component for lighting control is built so that only fluorescent glass tubes which have reached the end of their life can be replaced and reused. The socket 10 is mounted on the center of the body 30 so that the plug-in fluorescent glass tube 20 can be inserted and removed, and the refilling electronic appliance has a function of automatically turning off or turning on according to the surrounding light and dark. The structure and lighting control circuit of an old fluorescent lamp.
일반적으로 전자식 전구식 형광등 회로는 도 1에서 보인 바와 같이 교류전원을 전파정류하여 직류로 만든 다음 트랜지스터(1a)와 트랜지스터(1b)를 교대로 고속스위칭시켜 고주파를 만드는 인버터회로를 중심으로 하고 있다.In general, the electronic bulb-type fluorescent lamp circuit is centered on the inverter circuit to generate a high frequency by alternately high-speed switching the transistor (1a) and transistor (1b) by alternating the AC power to direct current as shown in FIG.
여기에 형광램프의 특성상 점등시 필라멘트(22)를 예열하기위한 과정이 필요한데 이 과정을 생략하고 높은 전압을 인가하여 인위적으로 방전을 개시하면 형광등의 수명이 단축되므로 기존의 회로에서는 콘덴서(5a), 콘덴서(5b), 서미스터(6)를 통하여 필라멘트를 가열하고 있다.This requires a process for preheating the filament 22 when it is turned on due to the characteristics of the fluorescent lamp. However, if this process is omitted and artificial discharge is started by applying a high voltage, the life of the fluorescent lamp is shortened. The filament is heated via the condenser 5b and the thermistor 6.
특히 서미스터는 초기점등시 저항값이 적어서 필라멘트에 많은 전류가 흘러 빠른 점등이 되는데 기여하지만 점등된 이후에도 일정전류가 계속 흐르면서 열을 발생하는 관계로 회로내부의 온도상승은 물론 고열로 인한 서미스터 자체열화에 의한 회로전체의 수명을 단축시키는 요소가 되고 있다.In particular, thermistor has a small resistance value at initial lighting, which contributes to rapid light-up due to a large amount of current flowing through the filament. It is a factor that shortens the lifetime of the entire circuit.
이러한 종래의 방법으로는 입력교류전압이 220V일때, 내압이 400V이상인 콘덴서(5a)와 내압이 600V이상인 콘덴서(5b), 그리고 발열소자인 서미스터주위의 여유공간 확보로 인하여 이들 부품을 다 사용하면서 몸체(30)의 중안에 큰 부피를 갖는 분리형 소켓(10)을 장착하는 것은 몸체를 기형적으로 키워야하는 구조적인 문제가 있었으며 따라서 사용자는 수명이 다한 형광유리관과 함께 아직 잔존수명이 있는 몸체까지 폐기하는 상태이다.In the conventional method, when the input AC voltage is 220V, the condenser 5a having a breakdown voltage of 400V or higher, the condenser 5b having a breakdown voltage of 600V or higher, and a spare space around the thermistor which is a heat generating element are used while the body is completely used. Mounting the detachable socket 10 having a large volume in the middle of (30) had a structural problem to grow the body deformed, so the user discards the body with the still life remaining with the fluorescent glass tube which has reached the end of its life to be.
또한 주야 자동 점소등 기능에 있어서는 햇빛을 기준으로하여 분광스펙트럼방식으로 하고 있기 때문에 햇빛이 아닌 다른 광원에 의하여 주위가 밝을 경우에도 램프가 켜짐으로써 에너지가 낭비되는 문제점을 갖고 있다.In addition, the day and night automatic flashing function has a problem in that the energy is wasted by turning on the lamp even when the surroundings are bright by a light source other than sunlight because it is a spectral spectrum method based on sunlight.
따라서, 본 고안은 상기와 같은 문제점을 해결하기 위하여 광원에 상관없이 주위의 밝고 어두움에 따라 자동 점소등되는 기능을 갖고, 수명이 다한 형광유리관만을 손쉽게 교환하여 재활용할 수 있는 리필용 전자식 전구식 형광등기구를 제조하는 방법을 제공하는 데 있다.Therefore, the present invention has the function of automatically turning on and off according to the surrounding bright and dark regardless of the light source to solve the above problems, and can be easily replaced by recycling only the fluorescent glass tube of the end of life refill electronic bulb-type fluorescent lamp To provide a method for producing a.

본 고안은 주위의 밝고 어두움에 따라 자동 점소등되는 기능을 갖고, 도 6에 보인 바와 같은 플러그방식의 형광유리관(20)을 끼우거나 뺄 수 있도록 플러그방식의 소켓(형식승인 전 1-3-1910)을 몸체(30)의 중앙에 장착시켜 간단하게 수명이 다한 형광유리관만을 교환함으로써 재활용이 가능한 리필용 전자식 전구식 형광등기구를 제조하기 위한 방법이다.The present invention has a function of automatically turning on and off according to the surrounding light and dark, and the plug-type socket to insert or pull out the plug-type fluorescent glass tube 20 as shown in Figure 6 (before type approval 1-3-1910 ) Is mounted on the center of the body (30) is simply a method for manufacturing a refillable electronic bulb-type fluorescent light fixture that can be recycled by replacing only the end of the fluorescent glass tube.
우선, 형광램프 필라멘트의 가열방식을 바꾸어 도 6에 보인 바와 같이 기존 상품화 되어있는 그로우스타터가 내장된 플러그방식의 형광유리관(20)을 사용함으로써 종래의 전자식 전구식 형광등의 회로에서 필라멘트 가열용 부품인 콘덴서 (5a), 콘덴서(5b)와 서미스터(6)를 사용하지 않아도 되고 따라서 부품수를 줄이는 효과가 있으며 특히 기존제품중 고장발생의 약20%를 차지하는 발열소자인 서미스터가 제거됨에따라 회로의 신뢰성이 증가된다.First, by changing the heating method of the fluorescent lamp filament, as shown in Figure 6 using a plug-type fluorescent glass tube with a built-in glow starter commercially available as a component for heating filament in the circuit of a conventional electronic bulb fluorescent lamp It is not necessary to use condenser (5a), condenser (5b) and thermistor (6), thus reducing the number of parts. Especially, the reliability of the circuit is eliminated by removing the thermistor, which is a heating element that accounts for about 20% of failures, among existing products. Is increased.
그로우스타터(23)에 의한 형광등 기동방식은 오래전 부터 사용되어온 방식으로 스위칭한 뒤 점등하기까지 2 - 3초 걸린다는 단점이 있으나 여기서는 부피가 큰 필라멘트 가열용 부품을 사용하지 않아도 될 뿐만 아니라 몸체와 형광유리관을 분리형으로 할 수 있는 두 가지 장점이 있다.The fluorescent lamp starting method by the glow starter 23 has a disadvantage that it takes 2 to 3 seconds to turn on after switching to the method which has been used for a long time, but here, it is not necessary to use a bulky filament heating part, but also a body and a fluorescent lamp. There are two advantages that can make the glass tube detachable.
또 방전전압을 유기하기 위하여 쵸크코일(4)이 사용되는데 이것이 전체회로에서 가장 부피가 크기 때문에 도 5에 보인 바와 같이 소켓(10)과 베이스(11)의 사이에 쵸크코일을 설치하는 구조로 한다.In addition, the choke coil 4 is used to induce the discharge voltage, and since it is the bulkiest in the entire circuit, the choke coil is provided between the socket 10 and the base 11 as shown in FIG. .
다음으로 어두우면 자동 점등되고 밝으면 자동 소등되는 기능에 관한 것으로써 도 2에 본 고안의 실시예에 따른 전체적인 회로를 도시하고 있으며 기능상 크게 두 분으로 구분할 수 있다. 도 2에서 상위회로는 스위칭 트랜지스터(1a,1b)를 중심으로 하여 형광램프를 점등하기 위한 전자식 안정기에 해당하는 부분이고 하위회로는 타이머(50)와 조도센서인 CDS(51)를 중심으로 한 자동 점소등 신호발생부분이며 트랜지스터(1c)를 통하여 상위부분의 안정기회로를 제어하게 된다.이하에서는 각 부분의 동작을 개별적으로 상세하게 설명한 후 마지막으로 두 부분의 인터페이스에 대하여 기술하기로 한다, 우선 전자식안정기부분에 대하여 기술한다. 전자식안정기회로는 도 1의 기존제품회로에서 형광램프의 필라멘트가열용 부품(5a,5b,6)을 글로우스타터(23)로 대체한 것을 제외하고는 동일하다. AC220V 전원이 공급되면 정류다이오드(D1-4)와 평활콘덴서(C1)로 직류를 만들고,저항(R3)를 통하여 콘덴서(C2)에 충전된 전하가 다이악(D6)을 통하여 트랜지스터(1a)의 베이스에 인가되면서 트랜지스터(1a)가 ON된다. 트랜지스터(1a)가 ON되면 콘덴서(C4)의 충전전류가 펄스트랜스코일(3a),쵸크코일(4)과 램프를 경유하여 증가함과 동시에 펄스트랜스코일(3c)에 순방향 유기기전력(5V PEAK)이 발생하여 트랜지스터(1a)는 ON상태가 지속된다. 콘덴서(C4)의 충전전압이 상승함과 더불어 충전전류가 감소하게되면 펄스코일(3c)에는 극성이 반대인 역방향 유기기전력이 발생하여 트랜지스터 (1a)는 OFF되고 펄스코일(3b)에 트랜지스터(1b)의 순방향 유기기전력이 발생하여 이번에는 트랜지스터(1b)가 ON되면서 전류방향이 반대인 콘덴서(C4)의 방전전류가 흐른다. 그러나 쵸크코일(4)의 인덕턴스로 인하여 전류방향이 급변하지 않으려고 하는 큰 역기전력이 발생하여 램프가 점등되고 다이오드(D8)은 이 역기전력의 통로가 된다. 트랜지스터(1b)를 통한 콘덴서(C4)의 방전전류가 감소하면서 펄스코일 (3c)의 유기기전력이 트랜지스터(1a)를 다시 ON상태로 만들고 트랜지스터(1b)는 OFF되면서 상기동작을 반복하여 약 35KHz의 스위칭이 이루어진다.다음으로 도 2의 아래부분회로의 명암에 따른 자동점소등 신호발생부분에 대하여 기술한다. 이 회로의 전원은 저항(R9),평활콘덴서(C5)와 제너다이오드(ZD)를 통하여 7.5V가 공급되고 신호레벨의 상세한 이해를 위하여 도 8의 신호 상관관계 도면으로 상술한다. 타이머(50)의 주변회로는 전형적인 펄스발생회로로서 단자(3)에서 약 10분 간격으로 약 200ms폭의 펄스(HIGH:6.5V LOW:0V)가 출력된다.이 펄스전압을 OP AMP(53)의 반전단자에 입력하여 저항(R12,R13,R14)에 의한 전압배분으로 HIGH:5.4V LOW:2.2V로 신호변환 후 슈미드트리거(52)의 반전단자에 입력한다.Next, as shown in FIG. 2, the overall circuit according to an embodiment of the present invention is shown as a function of automatically lighting when it is dark and automatically turning off when it is bright. In FIG. 2, the upper circuit corresponds to an electronic ballast for turning on a fluorescent lamp centering on the switching transistors 1a and 1b, and the lower circuit is an automatic centering around a timer 50 and a CDS 51 which is an illuminance sensor. It is the signal generating part of the lighting lamp and controls the ballast circuit of the upper part through the transistor 1c. Hereinafter, the operation of each part will be described in detail individually, and finally, the interface of the two parts will be described. The ballast section is described. The electronic ballast circuit is the same except for replacing the filament heating parts 5a, 5b, 6 of the fluorescent lamp with the glow starter 23 in the existing product circuit of FIG. When AC220V power is supplied, direct current is made by rectifying diode (D1-4) and smoothing capacitor (C1), and the charge charged in capacitor (C2) through resistor (R3) of transistor (1a) through diac (D6). Transistor 1a is turned on while being applied to the base. When the transistor 1a is turned on, the charging current of the capacitor C4 increases through the pulse transcoil 3a, the choke coil 4 and the lamp, and at the same time, the forward organic electromotive force (5V PEAK) is applied to the pulse transcoil 3c. This occurs, and the transistor 1a is kept in the ON state. When the charging voltage of the capacitor C4 increases and the charging current decreases, the reverse organic electromotive force of opposite polarity is generated in the pulse coil 3c, so that the transistor 1a is turned off and the transistor 1b is provided to the pulse coil 3b. Forward organic electromotive force is generated. This time, the transistor 1b is turned on, and the discharge current of the capacitor C4 in the opposite direction of the current flows. However, due to the inductance of the choke coil 4, a large counter electromotive force is generated that the current direction does not change suddenly, and the lamp is turned on, and the diode D8 becomes a path of the counter electromotive force. As the discharge current of the capacitor C4 through the transistor 1b decreases, the organic electromotive force of the pulse coil 3c turns on the transistor 1a again, and the transistor 1b is turned off, and the above operation is repeated. Switching is performed. Next, a description will be given of the auto-lighting signal generation portion in accordance with the contrast of the lower circuit of FIG. The power supply of this circuit is supplied with 7.5V through the resistor R9, the smoothing capacitor C5 and the zener diode ZD, and is detailed in the signal correlation diagram of FIG. 8 for a detailed understanding of the signal level. The peripheral circuit of the timer 50 is a typical pulse generating circuit, and a pulse (HIGH: 6.5V LOW: 0V) of about 200 ms in width is output from the terminal 3 at intervals of about 10 minutes. The pulse voltage is converted into the OP AMP 53. The signal is converted into HIGH: 5.4V LOW: 2.2V by the voltage distribution by the resistors R12, R13, and R14, and is input to the inverting terminal of the Schmid trigger 52.
주위가 점차 어두워 진다고 할 때 조도센서 CDS의 저항값이 증가하면서 슈미드트리거(52)의 비반전단자의 전압이 2.2V보다 커지면 출력전압이 HIGH(5.2V)로 되면서 저항(R16)을 통하여 트랜지스터(TR1)를 ON상태로 만들고 또 저항(R19)으로 비반전단자에 피드백되어 비반전단자전압이 3.5V로 증가되어 자신의 램프빛에 의하여 CDS저항값이 작아져도 램프가 꺼지지 않도록 하고 있다. 그러나 이런 상태가 지속되면 주위가 밝아져도 램프가 꺼지지 않기때문에 슈미드트리거(52) 반전단자에 약 10분간격으로 비반전단자전압 3.5V보다 큰 200mS펄스폭의 5.4V전압을 인가하여 슈미드트리거(52)의 출력전압을 LOW(0V)로 하면서 램프를 꺼지게한다.이렇게 함으로서 램프빛이 없는 순수한 주위의 명암을 판별하여, 밝으면 슈미드트리거(52)의 출력전압이 LOW가 되어 램프가 꺼진 상태로 있고,어두우면 출력전압이 HIGH가되어 램프가 점등된다.마지막으로 슈미드트리거(52)의 출력신호가 HIGH이면 점등되고 LOW이면 소등되는 전자식 안정기와의 인터페이스에 대하여 기술한다. 슈미드트리거(52)의 출력신호가 LOW(0V)이면 트랜지스터(TR1)가 OFF상태이고 이때 7.5V전압이 저항(R1)을 통하여 트랜지스터(1c)의 베이스에 0.7V 순방향 바이어스되어 트랜지스터(1c)가 ON된다. 그 결과 스위칭 트랜지스터(1a)의 베이스전압이 트랜지스터(1c)의 콜렉터-에미터로 바이패스되어 트랜지스터(1a)의 작동이 정지되고 램프가 켜질 수 없게 된다. 반대로 슈미드트리거(52) 출력전압이 HIGH(5.2V)이면 트랜지스터(TR1)가 ON되어 트랜지스터(1c)의 베이스전압이 0V가 되고 트랜지스터(1c)는 OFF된다. 그 결과 스위칭 트랜지스터(1a)의 베이스는 다이악(D6)에 의하여 트리거되면서 정상적인 스위칭동작이 시작되고 램프는 점등된다.When the ambient light gradually darkens, when the resistance value of the illuminance sensor CDS increases and the voltage of the non-inverting terminal of the Schmid trigger 52 becomes larger than 2.2 V, the output voltage becomes HIGH (5.2 V) and the transistor through the resistor R16. (TR1) is turned ON and the non-inverting terminal is fed back to the non-inverting terminal with the resistor R19 so that the non-inverting terminal voltage is increased to 3.5V so that the lamp does not turn off even if the CDS resistance value is reduced by its lamp light. However, if this condition persists, the lamp will not turn off even if the ambient light becomes bright. Therefore, the Schmid trigger is applied to the inverting terminal of the Schmid trigger 52 by applying a 5.4 V voltage of 200 mS pulse width greater than 3.5 V of the non-inverting terminal voltage every 10 minutes. The lamp is turned off while the output voltage of (52) is set to LOW (0 V). By doing so, the contrast of pure ambient light without lamp light is determined, and if it is bright, the output voltage of the Schmid trigger 52 becomes LOW and the lamp is turned off. In this case, the output voltage becomes HIGH and the lamp is turned on. Finally, the interface with the electronic ballast which is turned on when the output signal of the Schmid trigger 52 is HIGH and turned off when it is LOW will be described. When the output signal of the Schmid trigger 52 is LOW (0V), the transistor TR1 is in an OFF state, and at this time, the 7.5V voltage is forward biased to the base of the transistor 1c through the resistor R1, and thus the transistor 1c. Is turned on. As a result, the base voltage of the switching transistor 1a is bypassed to the collector-emitter of the transistor 1c so that the operation of the transistor 1a is stopped and the lamp cannot be turned on. On the contrary, when the Schmid trigger 52 output voltage is HIGH (5.2V), the transistor TR1 is turned on so that the base voltage of the transistor 1c becomes 0V and the transistor 1c is turned off. As a result, the base of the switching transistor 1a is triggered by the diaak D6, and the normal switching operation is started and the lamp is turned on.
상기한 바와 같이 광원의 분광스펙트럼에 관계없이 주위의 밝고 어두움에 따라 자동으로 점소등되는 기능을 갖으며, 몸체의 중앙에 소켓(형식승인 전 1-3-1910)을 장착하여 수명이 다한 플러그방식의 형광유리관만을 교환함으로써 몸체를 재활용할 수 있고, 플러그방식의 형광유리관은 이미 다양하게 상품화되어 있으므로 교환할 때 사용자의 취향에 맞는 램프를 선택하여 새로운 분위기를 연출할 수 있는 부수적인 효과도 있다.As described above, it has a function of automatically turning on and off according to the surrounding light and dark regardless of the spectral spectrum of the light source.It is equipped with a socket that has reached the end of its life by installing a socket (1-3-1910 before type approval) By replacing only the fluorescent glass tube of the body can be recycled, since the plug-type fluorescent glass tube is already commercialized in various ways, there is a side effect of creating a new atmosphere by selecting a lamp according to the user's taste when replacing.
