본 발명은 본 장치에 전원공급방식으로 전자식안정기, 자기식안정기, 래피드 스타트 안정기 및 상용전원 직결식 모두 사용이 용이하도록 발명하였다. 특히 전자식 안정기로 부터 전원을 공급받을 경우 LED 램프의 부하 변동에 따라 전자식안정기의 고주파 전압의 변동폭이 매우 크고 또한, 과전압이 출력되어 고장의 원인이 될 수 있다. 이를 극복하기 위해 본 발명에서는 다음과 같이 실시하고 있다.The present invention has been invented to facilitate the use of electronic ballasts, magnetic ballasts, rapid start ballasts and commercial power directly connected to the device as a power supply method. In particular, when the power is supplied from the electronic ballast, the variation of the high frequency voltage of the electronic ballast is very large according to the load variation of the LED lamp, and the overvoltage may be output, which may cause a failure. In order to overcome this, the present invention is carried out as follows.
먼저 형광등기구의 전자식안정기, 자기식안정기, 래피드 스타트 안정기, 상용전원 직결 방식중 어떤 방식이든 관계 없이 전원을 형광등기구의 전극단자로 부터 공급받기 위한 수단과, 자기식안정기, 래피트 스타트 안정기, 상용전원 직결방식은 LED 구동 모듈에 정전류 전원을 공급하기 위한 수단으로 PWM 방식으로 정전류제어 하고, 전자식안정기의 경우 LED 모듈의 부하변동에 관계없이 전자식안정기의 고주파 출력전압을 안정된 전압을 공급받기 위해 형광등의 히터에 대응하는 전류를 도 16과 같이 반도체 소자에 바이어스 또는, PWM 신호를 제어하여 전자식안정기의 고주파 출력전압을 일정하게 출력하기 위한 수단을 구비하여 LED 구동 모듈의 전력을 제어하여 밝기 조절을 할 수 있는 것을 특징으로 한 발명장치이다.First, the means for receiving the power supply from the electrode terminal of the fluorescent lamp, regardless of electronic ballast, magnetic ballast, rapid start ballast, commercial power supply of the fluorescent lamp fixture, magnetic ballast, rapid start ballast, commercial The direct power supply method is a means for supplying constant current power to the LED driving module.The constant current is controlled by PWM method.In the case of electronic ballasts, fluorescent lamps are used to receive a stable voltage for the high frequency output voltage of the electronic ballasts regardless of the load variation of the LED module. As shown in FIG. 16, a bias or a PWM signal is controlled to the semiconductor element to control the power output of the LED driving module to control the brightness of the electronic ballast. It is an invention apparatus characterized by the above-mentioned.
본 발명은 상술한 봐와 같이 기존 형광등 자리에 교체작업만으로도 에너지 절약을 할 수 있는 발명임을 설명하였다. 조명등의 종류는 직관형 형광등, U자형 형광등 등등 다양한 조명 형태가 있다. 본 발명에서는 직관형 형광등을 기준으로 발명의 실시 예를 설명하기로 한다. 또한, 당 분야 종사자라면 다른 형태의 조명등도 손쉽게 변경가능함을 잘 알고 있을 것이다. 따라서, 본 발명의 요지를 흐릴 수 있으므로 조명등의 각각의 구조별 별도로 설명하지 않기로 한다.As described above, the present invention has been described as being an energy-saving invention only by replacing the existing fluorescent lamp. There are various types of lighting, such as straight fluorescent, U-shaped fluorescent lamps. In the present invention, an embodiment of the present invention will be described based on a straight fluorescent lamp. In addition, those skilled in the art will appreciate that other types of lighting can be easily changed. Therefore, since the gist of the present invention may be obscured, it will not be described separately for each structure of the lamp.
실시 예1) 교류를 직류로 변환하기 위한 수단.Example 1 A means for converting alternating current into direct current.
LED는 직류전류에 의해 구동된다. 따라서 교류전압을 직류로 변환해야 한다. 물론 교류에 의해서도 점등이 되지만 정방향 전류가 흐를 때만 점등이 된다. 역방향일 때는 소등됨으로 밝기가 현저히 떨어지고 깜빡거림 현상이 발생한다. 본 발명에서는 상술한 것과 같이 다양한 방식의 전원입력을 받아야 한다. 먼저, 재래식 안정기 방식의 형광등 회로는 도 2의 202 전등관 회로가 구동될 때 고전압을 발생시켜 형광등을 점등시킨다. 또한, 전자식 형광등은 도 3과 같이 301, 302의 스위칭 소자에서 고주파 전압을 발생시켜 형광등을 점등시킨다. 상술한 두 가지 모두 형광등 전극 핀에 전압이 공급됨은 당연하다. 형광등 전극으로 들어오는 전압을 직류로 변환하여 LED 모듈을 점등해야 한다. 그러나 도 3과 같은 전자식 형광등의 경우는 제조사 및 형광등의 전력용량에 따라 다르지만 통상적으로 95V~160V, 25KHz~75KHz의 교류전압을 발생시켜 형광등 전극단자에 공급하고, 도 2와 같은 재래식 형광등은 상용(220V, 60Hz) 교류전압이 형광등 전극단자에 공급된다. 그리고 도 4와 같이 안정기 없이 직접 교류전압을 공급받을 때는 안정기에서 소비되는 전력이 없으므로 전력 효율이 극대화할 수 있지만 기존에 사용하던 형광등기구의 경우는 회로를 수정해야 하는 불편함이 있다. 하지만, 본 발명에서는 어떤 방법으로 전력을 공급받던 모두 동작하도록 하는 것이 특징이다.The LED is driven by direct current. Therefore, AC voltage must be converted into DC. Of course, the lamp is turned on by the alternating current, but only when the forward current flows. In the reverse direction, it turns off so that the brightness drops significantly and flickers. In the present invention, it is required to receive a power input of various methods as described above. First, the conventional ballast fluorescent lamp circuit generates a high voltage when the 202 light tube circuit of Figure 2 is driven to turn on the fluorescent lamp. In addition, the electronic fluorescent lamp generates a high frequency voltage in the switching elements 301 and 302 to turn on the fluorescent lamp as shown in FIG. Of course, both of the above-described voltage is supplied to the fluorescent electrode pin. The LED module should be turned on by converting the voltage coming into the fluorescent lamp electrode into direct current. However, in the case of the electronic fluorescent lamp as shown in Figure 3, depending on the manufacturer and the power capacity of the fluorescent lamp, but usually generates an AC voltage of 95V ~ 160V, 25KHz ~ 75KHz to supply to the fluorescent electrode electrode terminal, conventional fluorescent lamp as shown in Figure 2 is commercial ( 220V, 60Hz) AC voltage is supplied to the fluorescent electrode terminal. And when the direct AC voltage is supplied without a ballast as shown in FIG. 4, there is no power consumed in the ballast, so power efficiency can be maximized. However, the present invention is characterized in that all of the power is supplied in any way.
전자식 안정기의 경우 고주파 발진과 함께 전류제어를 하는 경우가 있는데 만약 DC전압을 얻기 위해 반파 정류회로로 구성하게 되면 도 3의 콘덴서 306, 307에서 정상적인 전력을 공급하지 못하고, 전자식 안정기가 오동작할 가능성이 매우 높다. 본 발명에서는 도 5와 같이 전파 정류회로방식을 사용하고, 특히 형광등의 전극단자에 히터 전류를 흘리기 위한 것과 병행되어 있으므로 실제로 어떤 단자에서 전력이 공급될지 알 수 없다. 따라서, 본 발명에서는 도 5의 501, 502의 접속단자는 동일한 기능을 가지므로 그중 한쪽 전극 501에 대한 예를 들면 단자 상부전극과 하부전극이 있는데 둘 중 한쪽 전극은 히터 전류를 공급하기 위한 점등관(202) 또는 점등 콘덴서(305)가 부착되고 한쪽 단자는 형광방전관에 전력을 공급하게 되어 있다. 따라서, 단자 접속이 어느 쪽으로 되어도 상관없이 전력을 공급받기 위해 브리지 정류회로 503, 504와 같이 이중으로 구성하여 전력을 공급받아 평활콘덴서 505를 부착하여 직류전원을 얻도록 하는 것을 특징으로 한다. 여기서, 퓨즈 506, 507은 한쪽 전극 501이나 502중 어느 쪽이든 관계없으나 도면에서는 전극단자 501에 연결하였다. 만약, 전극단자 501과 502에 각각 하나씩 퓨즈를 부착하게 되면 전압이 어느 쪽으로 입력될지 알 수 없으므로 퓨즈 부착이 의미가 없어질 수도 있다. 그리고 전자식 안정기의 음극전극 예열 방식일 경우 히터에 전력을 공급하고 있으며, 제조사에 따라 히터 전류를 검출하여 동작을 제어하는 경우가 있으므로 히터 전류를 흘려줄 필요가 있다. 이것은 전자식 안정기만 해당사항이 된다. 따라서, 전극 501 및 502의 각각의 전극양단에 저항을 부착해도 좋으나 저항은 발열이 심하여 본 발명에서는 508 및 509를 커패시터 또는 인덕턴스 성분이 있는 소자를 부착하여 발열을 줄이는 것을 특징으로 한다.In the case of the electronic ballast, there is a case of controlling the current with high frequency oscillation. If the half-wave rectifier circuit is configured to obtain the DC voltage, the capacitors 306 and 307 of FIG. 3 cannot supply normal power, and the electronic ballast may malfunction. Very high. In the present invention, a full-wave rectifying circuit method is used as shown in FIG. 5, and in particular, it is not known in which terminal the electric power is actually supplied because it is parallel to flowing a heater current to the electrode terminal of a fluorescent lamp. Therefore, in the present invention, since the connection terminals of 501 and 502 of FIG. 5 have the same function, for example, there is a terminal upper electrode and a lower electrode for one electrode 501, and one of the two electrodes is a light tube for supplying a heater current. 202 or a lighting capacitor 305 is attached, and one terminal supplies electric power to the fluorescent discharge tube. Therefore, in order to receive power regardless of which terminal connection is made, it is characterized in that a dual configuration, such as bridge rectifier circuits 503 and 504, receives power to attach a smoothing capacitor 505 to obtain a DC power source. Here, the fuses 506 and 507 may be connected to either the electrode 501 or the electrode 501 in either of the drawings. If one fuse is attached to each of the electrode terminals 501 and 502, the fuse may not be attached because it does not know which way the voltage is input. In the case of the cathode electrode preheating method of the electronic ballast, electric power is supplied to the heater, and according to the manufacturer, the heater current may be detected and the operation may be controlled to flow the heater current. This only applies to electronic ballasts. Therefore, although a resistance may be attached to each of the electrodes of the electrodes 501 and 502, the resistance is severely generated, and according to the present invention, 508 and 509 are attached to a device having a capacitor or an inductance component to reduce heat generation.
바람직한 정류회로의 실시 예로 도 7과 같은 회로를 제공한다. 주요내용으로 전자식 안정기 방식과 상용전원 방식의 전원을 분리하여 정류회로를 구성한 것이 특징이며, 먼저 전자식 안정기 방식은 전극단자 701, 702로부터 고주파 전력으로 공급되고 있으므로 커패시터 701, 702와 703, 704를 통해 고주파 전력을 분리하여 정류회로 714와 결합하여 평활콘덴서 716에 의해 직류성분을 만들고, 만약 상용전원 입력방식 또는, 재래식 안정기 방식을 통해 전력이 공급된다면 전극단자 701, 702를 통해 필터회로 711, 712, 713을 통해 정류회로 715와 결합하여 평활콘덴서 716에 의해 직류성분을 만든다. 콘덴서 711은 필터의 기본회로를 표현하기 위한 것이고, 전자식 안정기 방식일 때는 교류전력을 직접 공급받는 상태이므로 회로에는 도시되지 않았으나 필터회로에서 제거하거나 콘덴서와 인덕턴스를 직렬로 구성하여 전자식 안정기의 전력을 흡수되지 않도록 하는 것이 바람직할 것이다. 상기 상용전원 방식 또는, 재래식 안정기 방식을 통해 전력이 공급될 때는 701 및 702의 각각 두 전극단자를 단락시켜도 무방함으로 상용전원의 경우 인덕턴스에 대해 임피던스가 매우 낮아지는 원리에 의해 인덕턴스 705 및 706을 부착하여 전극단자에 단락효과를 얻을 수 있으며 이로 인하여 전원입력이 어떤 단자로 입력이 되어도 상관없이 정류회로가 정상동작을 할 수 있다. 또한, 인덕턴스 705 및 706은 제조사에 따라 전자식 안정기에서 히터전류를 검출하기 위한 목적이 있는 경우를 대비해서 705 및 706에 의해 히터회로가 정상으로 감지되도록 하게 하는 역할도 겸하고 있다. 고주파의 경우 인덕턴스 705 및 706의 임피던스가 높기 때문에 전자식 안정기의 히터 음극 예열 전력을 낭비하지 않도록 구성하는 것을 제공하고 있다. 그리고 상용전원 또는 재래식 안정기의 경우 과전압에 대한 보호회로가 필요하다. 도 7에 도시는 하지 않았지만 콘덴서 713과 병렬로 과전압(서지 전압) 보호소자를 부착하여 과전압에 대한 보호를 할 수 있다. 하지만, 전자식 안정기 방식의 전원 입력받을 경우는 과전압 보호회로가 전자식 안정기에 내장되어 있으므로 별도로 부착할 필요가 없을 것이다. 그러나 불가피하게 서지 보호소자를 부착해야 한다면 도시하지 않았지만 브리지 정류회로 714의 교류 입력단에 부착하면 효과를 볼 수 있겠다. 만약 도 3과 같은 기본 전원공급회로 방식으로 구성한다면 과전압 보호소자 및 노이즈 필터 소자를 부착한다면 전극 입력단자의 결선방법에 대해 경우에 수가 4가지이므로 각각 4개의 소자를 부착해야 하는 문제가 발생할 것이다. 상기와 같은 방식을 사용함에 따라 원가절감에 도움이 될 것이다.An embodiment of the preferred rectifier circuit provides a circuit as shown in FIG. The main feature is that the rectifier circuit is formed by separating the power supply of the electronic ballast method and the commercial power supply method. First, the electronic ballast method is supplied with high frequency power from the electrode terminals 701 and 702, so that the capacitors 701, 702 and 703, 704 The high frequency power is separated and combined with the rectifier circuit 714 to make a DC component by the smoothing capacitor 716. If power is supplied through the commercial power input method or the conventional ballast method, the filter circuit 711, 712, through the electrode terminals 701, 702, The DC component is made by the smoothing capacitor 716 in combination with the rectifier circuit 715 through 713. The capacitor 711 is intended to represent the basic circuit of the filter. In the case of the electronic ballast, the AC power is directly supplied. Therefore, although not shown in the circuit, the capacitor 711 is removed from the filter circuit or absorbs the power of the electronic ballast by configuring the capacitor and inductance in series. It would be desirable to avoid. When electric power is supplied through the commercial power supply method or the conventional ballast method, two electrode terminals of 701 and 702 may be shorted, respectively. Therefore, the inductances 705 and 706 are attached by the principle that the impedance is very low with respect to the inductance. Therefore, the short circuit effect can be obtained on the electrode terminal, and the rectifier circuit can operate normally regardless of which terminal the power input is input. In addition, the inductances 705 and 706 also serve to allow the heater circuit to be normally detected by the 705 and 706 in preparation for the purpose of detecting the heater current in the electronic ballast according to the manufacturer. In the case of high frequency, since the impedance of inductances 705 and 706 is high, it is provided that the heater cathode preheating power of the electronic ballast is not wasted. In the case of commercial power supplies or conventional ballasts, a protection circuit against overvoltage is required. Although not shown in FIG. 7, an overvoltage (surge voltage) protection device may be attached in parallel with the capacitor 713 to protect against overvoltage. However, when the electronic ballast is input, the overvoltage protection circuit is built in the electronic ballast so that it does not need to be separately attached. However, if the surge protection device is inevitably attached, it is not shown, but it can be applied to the AC input terminal of the bridge rectifier circuit 714. If the overvoltage protection device and the noise filter device are attached to the basic power supply circuit as shown in FIG. 3, the number of four devices should be attached to the method of connecting the electrode input terminals. Using the above method will help to reduce the cost.
상기 도 7과 같은 방식은 재래식 형광등의 스타트 점등관을 제거하고 사용하는 것이 바람직하고, 만약 제거하지 않고 사용할 경우 퓨즈 703 및 704중에 점등관과 연결된 회로에 결선 되어 있는 퓨즈가 단선이 될 것이다. 이것은 최초 구동할 때 퓨즈 해당 퓨즈가 단선 되고, LED 램프가 동작하게 된다. 상기와 같이 최초 1회 때 점등관에 연결된 회로의 퓨즈를 단선 되도록 해야 한다. 이와 같은 불편함을 해소하기 위해 도 8과 같은 방식의 직류로 변환 회로를 제공한다. 도 8에서 전극단자 801과 802를 통해서 교류전압을 공급하고 접속단자 801의 전극 a와 전극 a'와 퓨즈 803, 804를 각각 접속하고 인덕턴스 필터 805는 제조사에 따라 전자식 안정기에서 음극 예열 방식의 히터전류를 검출하기 위한 목적이 있는 경우를 대비해서 필터 805에 의해 고주파 전류를 흘려주어서 히터회로가 정상으로 감지되도록 한다. 여기서, 도면상에는 인덕턴스와 커패시터를 직렬로 구성하였으나 커패시터만 부착하여도 목적을 달성할 수 있다. 전극단자 802의 전극 b와 전극 b'와 필터 807과 접속한다. 필터 807은 필터 805와 같은 역할을 하고 있으며, 도면상에는 인덕턴스와 커패시터를 병렬로 접속되어 있지만 인덕턴스만 부착하여도 같은 효과를 얻을 수 있다. 또한, 상용전원 입력에 대해서는 단락효과를 가지도록 하는 효과가 있다. 따라서 정류 다이오드 806, 808, 809에 의해 반 이중 브리지 정류회로서 형광등의 전극단자의 방향에 관계없이 정류회로가 동작하도록 하기 위한 목적이고 평활콘덴서 811에 의해 직류로 변환한다. 본 발명은 일정시간 동안 유동체를 감지하지 못하였을 때에 LED램프를 소등할 경우 전류가 거의 흐르지 않으므로 이로 인하여 일부 전자식 안정기에 따라 전자식 안정기가 동작을 하지 않도록 하는 경우를 방지하기 위해 저항 717 과 810에 의해 일부 미약한 전력을 소비할 수 있도록 하고 있다. 여기서, 도면상에는 저항을 표기하였지만 스위칭 반도체 소자와 직렬로 부착하여 필요할 때만 반도체 소자를 구동하여 전력을 소비하도록 하는 것이 바람직하겠다. 상기 미약 전력을 소비하도록 하기 위한 목적은 전자식 안정기가 정상작동하도록 하여 본 발명의 마이컴 주변회로가 작동을 위해 최소 전원이 필요하기 때문이다.In the method as shown in FIG. 7, it is preferable to remove and use a start lamp tube of a conventional fluorescent lamp. If not used, the fuse connected to the circuit connected to the lamp tube among the fuses 703 and 704 will be disconnected. This is the first time the fuse is blown and the LED lamp is activated. As above, the fuse of the circuit connected to the lighting tube should be disconnected at the first time. In order to solve this inconvenience, a DC-to-DC conversion circuit as shown in FIG. 8 is provided. In FIG. 8, an AC voltage is supplied through the electrode terminals 801 and 802, and the electrode a, the electrode a 'of the connection terminal 801, and the fuses 803 and 804 are respectively connected, and the inductance filter 805 is the heater current of the cathode preheating type in the electronic ballast according to the manufacturer. In order to detect the problem, the high-frequency current flows through the filter 805 so that the heater circuit is normally detected. Here, although the inductance and the capacitor are configured in series on the drawing, the purpose can be achieved by attaching only the capacitor. The electrode b of the electrode terminal 802, the electrode b ', and the filter 807 are connected. The filter 807 plays the same role as the filter 805. Although the inductance and the capacitor are connected in parallel in the drawing, the same effect can be obtained by attaching only the inductance. In addition, there is an effect to have a short circuit effect for the commercial power supply input. Therefore, the rectifier circuit 806, 808, 809 is a half-duplex bridge rectifier for the purpose of allowing the rectifier circuit to operate regardless of the direction of the electrode terminal of the fluorescent lamp and converted to direct current by the smoothing capacitor 811. In the present invention, when the LED lamp is turned off when the fluid is not sensed for a certain time, almost no current flows, and therefore, the resistors 717 and 810 are used to prevent the electronic ballast from operating according to some electronic ballasts. Some weak power can be consumed. Here, although the resistance is indicated in the drawing, it is preferable to attach the power in the semiconductor device only when necessary by attaching it in series with the switching semiconductor device. The purpose of consuming the weak power is to allow the electronic ballast to operate normally so that the microcomputer peripheral circuit of the present invention requires a minimum power source for operation.
경우에 따라서는 전자식안정기만 동작하도록 할 필요가 있다. 도 19의 커패시터 1905, 1906, 1907, 1908에 의해 전자식안정기의 고주파 전력만 통과하도록 하여 1909, 1910의 정류회로와 1911 필터를 부착하여 정류회로를 구성하고, 상기 정류회로의 전원을 이용하여 LED를 구동하면 된다. 만약 재래식 안정기나 상용전원을 입력하였을 경우 동작을 하지 않으므로 안전사고를 예방할 수 있는 특징이 있다.In some cases, it is necessary to operate only the electronic ballast. The rectifier circuits of 1909 and 1910 and a 1911 filter are attached to each other to pass only the high frequency power of the electronic ballast by the capacitors 1905, 1906, 1907, and 1908 of FIG. 19, and the LEDs are formed by using the power of the rectifier circuit. You just need to drive. If the conventional ballast or commercial power is input, it does not operate, so it is possible to prevent safety accidents.
상기 교류 전원을 직류 전원으로 변환한 것을 PWM 전류제어 모듈을 통해 LED 램프를 점등할 수 있다. 여기서, PWM 모듈은 마이컴과 결합하여 PWM신호를 만들 수도 있고, 전용 칩으로 구성된 반도체 소자를 이용하여 정전류 전원을 구성할 수도 있다. 본 발명에서는 이 두 가지 모두 사용하여 좀더 효과적이고 시스템 동작에 안정성이 있도록 하고 있다. PWM 전용 칩에서는 설정된 최대전류를 제한하여 LED램프에 전력을 공급하여 마이컴 제어부가 작동을 하지 않아도 LED램프는 PWM 전용 칩에 의해 최대 전류 이상 공급되지 않도록 하고, 램프의 밝기나 점등 또는 소등은 마이컴 제어부에서 PWM 전류제어 구동모듈에 듀티 제어 신호를 변화하여 제어할 수 있다. 상기와 같은 방법은 제품생산시에 램프의 밝기 제어나 유동체 감지에 의한 다기능이 필요없는 경우 해당 부품을 삽입하지 않고 생산하여도 정상 동작을 할 수 있는 장점이 있다.The conversion of the AC power source to the DC power source may turn on the LED lamp through the PWM current control module. Here, the PWM module may be combined with a microcomputer to generate a PWM signal, or may configure a constant current power supply using a semiconductor device composed of a dedicated chip. In the present invention, both are used to make the system more effective and stable in the operation of the system. PWM dedicated chip supplies power to LED lamp by limiting the set maximum current so that the LED lamp is not supplied more than the maximum current by PWM dedicated chip even if the microcomputer controller does not operate. Can be controlled by changing the duty control signal to the PWM current control drive module. The method as described above has the advantage that it can operate normally even if the production without inserting the corresponding parts, if the multifunctional by the brightness control of the lamp or the fluid detection is not necessary at the time of production.

형광등 전극단자 101을 통해 전극방향에 관계없이 전파정류를 할 수 있는 반 이중 또는 이중 브리지 정류회로 102에서 직류전원을 만들고, 마이컴용 정전압 발생기 107에서 마이컴에 전원을 공급하고, 마이컴 연산 및 제어모듈 103에서는 조도센서 모듈 104로부터 검출된 빛의 양을 사전에 설정된 값과 비교하여 LED 램프모듈 111을 점등 또는 소등할 수 있도록 하고, 경우에 따라서는 검출된 조도에 따라 LED 램프모듈의 빛의 밝기를 제어할 수 있도록 한다. LED 램프모듈을 구동하기 위해서는 전류제어 방식이 가장 적합함으로 마이컴 연산 및 제어 모듈에서 사전에 램프의 밝기에 대응하는 전류 데이터를 메모리에 저장하여 두고, PWM 전류제어 구동모듈 108을 LED 램프 밝기 선택에 따라 상기 메모리에 저장한 데이터와 반 이중 또는 이중 브리지 정류회로의 직류전압과 연산처리하여 PWM신호를 생성 및 제어하고, 필터회로 109에서 고주파 성분을 제거 후 직류로 변환하고, 전류검출 모듈 110을 경유하여 LED 램프모듈을 점등시킨다. 여기서, 전류검출 모듈로부터 전류를 검출 받아 마이컴 연산 및 제어 모듈로 보내고, 마이컴 연산 및 제어 모듈에서 LED 램프모듈에 흐르는 전류를 보정 하도록 한다. 112-1, 112-n은 112의 블록과 동일하며, LED 조명 전력(밝기)에 따라 블록 수는 달라질 수 있다. 상기 LED 블록에서 전류검출 및 제어를 개별 검출하여 제어하는 것으로 도시하였으나 특별히 정밀한 제어가 요구되지 않으므로 LED 램프만 직렬 또는 병렬로 추가하고 전체전류를 검출 후 전류를 보정하여도 무방하다. Create a DC power source in the half-duplex or double-bridge rectifier circuit 102 capable of full-wave rectification irrespective of the electrode direction through the fluorescent lamp electrode terminal 101, supply the power to the microcomputer in the microcomputer constant voltage generator 107, and the microcomputer operation and control module 103 The LED lamp module 111 can be turned on or off by comparing the amount of light detected from the illuminance sensor module 104 with a preset value, and in some cases, the brightness of the LED lamp module is controlled according to the detected illuminance. Do it. In order to drive the LED lamp module, the current control method is most suitable. In the microcomputer operation and control module, the current data corresponding to the brightness of the lamp is stored in the memory in advance, and the PWM current control driving module 108 is selected according to the LED lamp brightness selection. The data stored in the memory and the DC voltage of the half-duplex or double-bridge rectifier circuit are processed and generated to generate and control the PWM signal.The high-frequency component is removed from the filter circuit 109 and then converted to direct current. Turn on the LED lamp module. Here, the current is detected from the current detection module and sent to the microcomputer operation and control module, and the microcomputer operation and control module corrects the current flowing in the LED lamp module. 112-1 and 112-n are the same as the blocks of 112, and the number of blocks may vary according to the LED lighting power (brightness). Although it is shown that the current detection and control in the LED block to individually detect and control, since no precise control is required, only the LED lamps may be added in series or in parallel, and the current may be corrected after detecting the entire current.
램프의 밝기를 제어하기 위해 도면상에는 도시하지 않았지만 반 이중 또는, 이중 브리지 정류회로에서 나온 전압을 마이컴 연산 및 제어 모듈에서 입력받아 필요한 전력을 전압에 대한 전류를 연산하여 PWM 신호발생 하도록 한다. 상기 PWM 신호를 PWM 전류제어 구동 모듈에서 입력받아 PWM 전류제어 구동 모듈을 구동하여 LED 램프 모듈로 전력을 공급하고, 상기 PWM 전류제어 구동모듈은 안정된 정전류 전원을 공급하기 위해 전류검출 모듈로부터 전류를 입력받아 오차 부분을 바로잡아 PWM신호 생성을 보정하여 출력하고, 상기 보정 과정을 반복하여 안정된 정전류 구동이 되도록 하는 것을 특징으로 하는 것을 제공한다.Although not shown in the drawing to control the brightness of the lamp, the voltage from the half-duplex or double-bridge rectifier circuit is input from the microcomputer operation and control module to generate the PWM signal by calculating the current for the voltage. The PWM signal is input from the PWM current control driving module to drive the PWM current control driving module to supply power to the LED lamp module, and the PWM current control driving module inputs current from the current detection module to supply stable constant current power. In response, the error portion is corrected and the PWM signal generation is corrected and outputted, and the correction process is repeated to provide a stable constant current drive.
본 발명장치는 다양한 전원입력을 받기 때문에 입력되는 전압의 범위가 매우 넓다. 따라서, 전력효율을 높이기 위해서 PWM 구동시 부스터 컨버터 회로 보다는 고주파 변압기를 이용하여 1차 측에 PWM 전력구동을 하고, 2차 측에 직류전압으로 변환하여 LED 램프에 전류를 공급하는 것이 바람직하다.The apparatus of the present invention receives a variety of power inputs, so the range of input voltages is very wide. Therefore, in order to increase power efficiency, it is preferable to supply a current to the LED lamp by converting the PWM power to the primary side using a high frequency transformer rather than a booster converter circuit during PWM driving and converting the DC voltage to the secondary side.
상용 교류 전원 입력 또는, 재래식 안정기의 전원입력 때에 역률 보상을 위해서 정류회로에 PFC(Power Factor Correction)회로를 부가하고, PWM 구동시 발생하는 고주파 노이즈를 제거하기 위한 전원필터를 추가하여 좀더 효과적인 절전 LED 조명등을 제공할 수 있겠다. 역률 보상을 상기와 같이 정류회로에서 하는 방법도 있지만 본 발명에서는 마이컴 제어부에서 연산처리하여 역률을 보상하도록 한다. 그 구성방법으로 LED에 흐르는 전류를 흘리면 정류회로의 1차 직류전압은 전원주파수의 2배에 해당하는 맥류형태로 나오게 된다. 1차 직류전원 평활회로의 맥류 전압을 마이컴 제어 모듈에서 실시간 읽어 전압에 대한 위상을 연산하고, 상기 위상에 따라 PWM 구동모듈에 PWM 신호를 실시간 생성하거나, PWM 구동모듈에 듀티 비율을 조절하여 역률을 개선할 수 있도록 실시간 연산처리하거나, 사전에 최적화된 위상에 대응하는 전류 데이터를 마이컴 메모리에 저장하여 두고, PWM 구동모듈에 PWM 신호를 실시간 생성하거나, PWM 구동모듈에 듀티 비율을 조절하여 역률을 개선할 수 있도록 하고, 만약, LED램프의 밝기 설정에 대응할 경우 그 밝기에 대한 전류 비율에 따라 전압 위상에 대응하는 전류를 연산하여 동작하도록 한다. 상기와 같은 방식으로 역률 개선하는 것을 특징으로 한다. More efficient power saving LED by adding PFC (Power Factor Correction) circuit to rectifier circuit for power factor correction at commercial AC power input or power input of conventional ballast, and adding power filter to remove high frequency noise generated during PWM driving. Could provide lighting. Although the power factor correction is performed in the rectifier circuit as described above, in the present invention, the microcomputer control unit calculates the power factor. When the current flowing through the LED flows, the primary DC voltage of the rectifier circuit comes out in the form of a pulse that corresponds to twice the power frequency. Read the pulse voltage of the primary DC power smoothing circuit in real time from the microcomputer control module to calculate the phase of the voltage, and generate the PWM signal in real time according to the phase, or adjust the duty ratio in the PWM drive module to adjust the power factor. Improves the power factor by real-time arithmetic processing, or by storing current data corresponding to a pre-optimized phase in the microcomputer memory, generating a PWM signal in real time in the PWM driving module, or adjusting the duty ratio in the PWM driving module. If it corresponds to the brightness setting of the LED lamp, it operates by calculating the current corresponding to the voltage phase according to the current ratio for the brightness. It is characterized by improving the power factor in the same manner as described above.

As a means for detecting fluids, infrared light emitting and receiving infrared diodes, an ultrasonic sensor, a Doppler sensor module, and the like can be easily used in various ways. Among the sensors listed above, a Doppler-type sensor may be effective, but a method of detecting by an infrared light-transmitting diode may be good to reduce production cost. The sensor method is not limited to the Doppler sensor module and the infrared light-receiving sensor, and it will be appreciated that various sensors may be attached and used as a means for achieving the above object. If the Doppler sensor module is used, the Doppler sensor module is converted into a voltage according to the movement of the fluid and output. Therefore, the microcomputer control module monitors the voltage change and provides power to increase the power efficiency by turning off the LED lamp or controlling the brightness according to the amount of voltage change. If an infrared light emitting diode is used, it can be carried out as follows. In order to prevent data collision with the infrared remote controller, the infrared light emitting diode 105 is supplied with a high frequency current at regular intervals, and the infrared light emitting diode detects the amount of light reflected by the infrared light emitting diode and passes only a high frequency component. It can be amplified and converted to a voltage through and sense the movement of the fluid in response to the voltage change. In the present invention, the infrared detection and communication module 106 filters and amplifies and converts the voltage to the microcomputer operation and control module so as to obtain the same effect in place of the above-described infrared light receiving diode. The microcomputer operation and control module reads the voltage according to the fluid change and provides an LED lamp module for turning on and off the LED lamp module for a predetermined time and increasing power efficiency through brightness control. The infrared detection and communication module not only detects the fluid movement but may also function to receive an infrared remote controller, or may be configured separately. Embodiments related to the remote control may be as follows.
리모컨의 적외선 신호와 상술한 유동체 검출을 위한 적외선 신호의 혼선을 막기 위해 리모컨의 적외선 고주파 신호와 다르게 할 필요가 있다. 따라서, 본 발명에서는 일반적인 TV(텔레비전), 전축 등의 적외선 리모컨의 주파수와 유동체를 구별하기 위한 적외선 검출 주파수를 다르게 하여 각각 수신시 고주파 필터를 만들어 분리하도록 한다.In order to prevent crosstalk between the infrared signal of the remote controller and the infrared signal for detecting the fluid described above, it is necessary to be different from the infrared high frequency signal of the remote controller. Therefore, in the present invention, by varying the frequency of the infrared remote control such as a general television (television), all-axis, and the infrared detection frequency for distinguishing the fluid, it is made to separate the high-frequency filter at the time of reception.

실시 예4) LED 정전류 구동 드라이브 방식Example 4 LED constant current drive method
현재 LED 구동을 위한 여러 가지 방법을 이용하고 있지만 스위칭 구동 드라이브의 반도체 소자에서 열이 많이 나고 있음을 익히 잘 알고 있을 것이다. 또한, 그 열로 인하여 스위칭 소자가 파손될 경우 전원 측에 단락현상과 동일한 현상이 발생하고 이로 인해 화재의 위험이 많이 있다. 대부분 LED BUCK 정전류 안정화 전원방식을 사용하는 예가 많으며, 이 경우 한 가지 고정된 전압에서는 크게 무리가 없으나 본 발명은 전자식 안정기의 전원 입력방식과 상용전원 입력방식 모두 동작을 해야 함에 따라 예를 들면 전자식 안정기 PL40 기준으로 보면 고주파 출력전압이 대략 100V 전후로 출력된다. 따라서, 1차 정류회로에서 대략 직류 80V ~ 340V 까지 광범위하게 동작을 해야 하는 어려움이 있다. LED BUCK 안정화 전원방식은 직류전원 출력 단자와 LED 램프 모듈과 인덕턴스 그리고, 스위칭 구동 소자 및 전류 검출 저항과 함께 직렬로 구성되는 것이 일반적 사례이다. 상술한 것과 같이 스위칭소자가 파손될 경우 상당히 위험한 상황이 발생하며, 특히 상술한 봐와 같이 회로의 구성이 직류 전원부와 직렬로 구성이 되어 있어 구동 스위칭 반도체에 전류가 흐르게 되면, FET의 경우 DRAIN과 SOURCE, 트랜지스터의 경우는 COLLECTOR와 EMITTER간에 도 15의 1501과 같이 인덕턴스 특성에 의해 전압강하가 발생하여 스위칭 소자에 열화가 발생한다. 또한, 인덕턴스에도 많은 전력손실이 발생하게 되는 문제가 있다.Although many methods are currently used to drive LEDs, you are familiar with the fact that the semiconductor devices of switching drive drives generate a lot of heat. In addition, when the switching element is damaged due to the heat, the same phenomenon as that of a short circuit occurs on the power supply side, which causes a lot of fire. There are many examples that use LED BUCK constant current stabilization power method, and in this case, it is not too much at one fixed voltage, but the present invention is required to operate both power input method and commercial power input method of electronic ballast. Based on PL40, high frequency output voltage is output around 100V. Therefore, there is a difficulty in operating a wide range of approximately 80 V to 340 V in the primary rectifier circuit. In general, the LED BUCK stabilized power supply is configured in series with a DC power output terminal, an LED lamp module, an inductance, a switching driving element, and a current sense resistor. As described above, a dangerous situation occurs when the switching element is damaged. In particular, as described above, when the circuit is configured in series with the DC power supply, when a current flows in the driving switching semiconductor, in the case of the FET, DRAIN and SOURCE In the case of a transistor, a voltage drop occurs due to an inductance characteristic between 150 COLLECTOR and the EMITTER as shown in 1501 of FIG. In addition, there is a problem that a lot of power loss occurs in the inductance.
상술한 LED BUCK 정전류 안정화 전원방식의 스위칭 드라이브 단에 문제를 해소하기 위해 본 발명에서는 도 12와 같이 푸시풀(PUSH-PULL) 스위칭 방식으로 드라이브 단에 인덕턴스와 커패시터의 직렬조합으로 발명한 것이 특징이다.In order to solve the problem of the LED BUCK constant current stabilized power supply switching drive stage, the present invention is characterized in that the invention is invented by a series combination of inductance and capacitor in the drive stage in the push-push switching mode as shown in FIG. .
도 12는 정전류 PWM 구동회로로서 PWM 구동소자 또는, PWM 신호발생기 1201에서 저항 1202, 1204를 통해 푸시풀 스위칭 드라이브 소자 1203, 1205의 GATE에 각각의 구동 펄스를 발생시키되 도 13과 같이 GATE1과 GATE2는 서로 반대의 구동 펄스를 만들어 스위칭소자에 공급한다. 이때, 도 14의 1401처럼 서로 구동 펄스가 충돌하지 않도록 ON할 때 약간씩 지연시간을 주는 것이 바람직하고, 상기 푸시풀 스위칭 드라이브 출력단에 커패시터 1206과 고주파 트랜스 1207의 1차 측과 직렬로 회로 구성하여 고주파트랜스 2차 측에 전압을 유기시킨다. 상기 1206과 1207은 직렬 구성이므로 서로 위치가 바뀌어도 무관하겠다. 그리고 고주파 트랜스 1207의 1차 측에 정류 다이오드 1208과 커패시터 1210에 의해 2차 직류전압을 만들고 상기 2차 출력전압에 LED 램프 모듈 1211을 부착한다. LED 램프 모듈은 정전류 구동을 해야함으로 LED 램프 모듈에 전류를 검출할 수 있도록 저항과 직렬로 구성하고, 검출된 전류를 PWM 구동회로 또는 마이컴 연산 및 제어 모듈의 전류검출 입력단에 전송하고 마이컴 연산 및 제어 모듈에서 PWM 신호발생기를 통해 정전류를 구동할 수 있도록 연산처리 한다. 또한, 미세 전류조정을 위해 1212에 일반 볼륨을 부착하여 조정하거나, LED 램프 밝기 조절을 위해 전자볼륨 1212를 부착해서 마이컴 연산 및 제어 모듈에서 전류제어신호 1213에 전송하여 램프 밝기를 제어할 수도 있다. 본 발명에서는 다양한 방법으로 램프의 밝기를 제어하거나 ON/OFF 하는 것을 제공하고 있다. 필요에 따라 적절한 방법을 사용하면 될 것을 생각한다.FIG. 12 is a constant current PWM driving circuit which generates respective driving pulses to the GATE of the push-pull switching drive devices 1203 and 1205 through the resistors 1202 and 1204 in the PWM driving device or the PWM signal generator 1201. The driving pulses opposite to each other are made and supplied to the switching element. In this case, as shown in 1401 of FIG. 14, it is preferable to give a delay time when the driving pulses do not collide with each other, and a circuit is configured in series with the primary side of the capacitor 1206 and the high frequency transformer 1207 at the push-pull switching drive output terminal. The voltage is induced on the secondary side of the high frequency transformer. Since 1206 and 1207 are serial configurations, the positions 1206 and 1207 may be changed. The secondary DC voltage is formed by the rectifier diode 1208 and the capacitor 1210 on the primary side of the high frequency transformer 1207 and the LED lamp module 1211 is attached to the secondary output voltage. Since the LED lamp module needs constant current driving, it is configured in series with a resistor to detect current in the LED lamp module, and transfers the detected current to the current detection input terminal of the PWM driving circuit or the microcomputer operation and control module, and the microcomputer operation and control. The module processes the current to drive constant current through the PWM signal generator. In addition, it is possible to control the lamp brightness by attaching a general volume to the 1212 for fine current adjustment, or by attaching an electronic volume 1212 to control the LED lamp brightness and transmitting it to the current control signal 1213 from the microcomputer calculation and control module. The present invention provides for controlling or turning on / off the brightness of the lamp in various ways. I think you can use the appropriate method according to your needs.
본 발명에서 전자식 안정기의 전원을 입력받을 경우에 램프를 소등할 경우 부하전류가 거의 흐르지 않으므로 전자식 안정기의 제조사에 따라 본 발명의 정류회로에 전압이 매우 높아지게 된다. 본 발명에서는 상기의 문제를 해소하는 것을 제공하고 있다. 도 16은 113의 구체적인 도면으로 램프를 소등할 경우 전자식 안정기의 출력전압을 조절할 수 있도록 하기 위한 장치이며, 도 5, 도 7, 도 8에는 전극단자 양쪽 모두 히터에 대응되는 전류를 흘려주기 위한 저항, 커패시터, 인덕턴스를 단독 또는, 직렬 또는, 병렬로 구성하여 전자식 안정기가 동작을 정상적으로 할 수 있도록 유도하고 있다. 그러나 본 발명에서는 에너지 절약을 위해 소등을 할 경우 상술한 봐와 같이 전자식 안정기의 출력전압이 매우 높게 나오기 때문에 이때는 전자식 안정기가 출력전압이 나오지 않도록 하는 것이 바람직하다. 물론 전자식 안정기는 무 부하 상태일 때는 출력 전압이 짧은 시간 동안 반복적으로 출력됨으로 본 장치의 마이컴 제어 회로에 필요한 전력은 충분히 얻을 수 있다. 또한, 전자식 안정기의 제조사에 따라 출력전압의 차이가 커서 히터에 대응하는 전류를 조절하여 출력전압을 필요한 전압을 얻을 수 있다. 실제 전자식 안정기 내부에는 일정 출력전압보다 높을 경우 스위칭 구동회로가 동작을 잠시 정지하도록 하고 있다. 전자식 안정기의 회로인 도 3을 보면 히터 전극과 스위칭 구동부와 트랜스포머 303, 히터, 커패시터 305와 직렬로 회로구성이 되어 있다. 따라서, 양쪽의 히터 전극 중 어느 한쪽이라도 회로가 단선 된다면 스위칭 구동부는 출력전압을 되먹임된 값에 따라 출력전압을 차단하거나 조절하게 된다. 만약 히터에 대응하는 단자에 전류를 많이 흘리게 되면 전자식 안정기의 출력 전압이 높을 수밖에 없을 것이다. 히터에 대응하는 전류를 흘려주기 위해 도 5, 도 7, 도 8 모두 같은 방법이지만 기본 도면인 도 5의 경우 508, 509, 도 7의 경우 705, 706, 도 8의 경우 805, 807 대신 도 16의 (16-A) 또는, (16-B)와 같은 회로를 추가로 부착한다. 먼저, (16-A)은 히터에 대응하는 전류를 흘리기 위한 것이 두 개가 필요하지만 동일한 도면이므로 한쪽 부분만 도시하고 설명하기로 한다. 또한, 상기 히터에 대응하는 전류를 한쪽만 제어 한다면 다른 한쪽 히터에 대응하는 단자는 적절한 임피던스를 가지는 소자를 부착해주면 될 것이다. 1601, 1601'는 상기 히터에 대응하는 전류를 흘려주기 위한 위치에 연결하고, 이때 도 16에는 도시하지 않았지만 고주파 전류만 입력되도록 커패시터를 추가 부착하여도 무방하다. 전극 양단에 정류회로 1602와 커패시터 1603을 부착하고, 저항 1604와 트랜지스터 1605와 직렬로 구성한다. 상기 저항은 꼭 저항으로만 국한할 필요는 없으며, 동작방식에 따라 1608을 단락하여 저항 없이 연결하여도 되고, 인덕턴스로 대체하거나 저항과 직, 병렬로 구성하여도 무관하다. 상기 트랜지스터에 바이어스에 따라 히터 전극에 대응하는 입력단자 전류를 조절할 수 있고, 만약 안정기의 출력전압을 능동적으로 제어할 때 도 5, 도 7, 도 8의 정류회로의 출력 전압을 검출하여 트랜지스터 베이스 입력단에 바이어스 전류를 조절하여 전자식 안정기 출력전압을 조절할 수 있다. 만약 전자식 안정기의 출력 전압이 높을 경우 바이어스 전류를 낮게 하고, 전자식 안정기의 출력전압이 낮을 경우 바이어스 전류를 높게 흘려주면 안정된 전압을 얻을 수 있다. 또한, 바이어스 전류를 흘리지 않으면 전자식 안정기는 간헐적으로 출력전압이 나오게 된다.In the present invention, when the lamp is turned off when the power of the electronic ballast is input, since the load current hardly flows, the voltage is very high in the rectifier circuit of the present invention according to the manufacturer of the electronic ballast. The present invention is to solve the above problems. FIG. 16 is a detailed diagram of 113 and a device for adjusting an output voltage of an electronic ballast when a lamp is turned off. In FIGS. 5, 7 and 8, a resistor for flowing a current corresponding to a heater in both electrode terminals is illustrated in FIG. The capacitors and inductances are configured alone, in series, or in parallel to induce the electronic ballast to operate normally. However, in the present invention, when the light is turned off for energy saving, the output voltage of the electronic ballast is very high as described above. In this case, it is preferable that the electronic ballast prevents the output voltage. Of course, when the electronic ballast is unloaded, the output voltage is repeatedly output for a short time, so that the power required for the microcomputer control circuit of the device can be sufficiently obtained. In addition, according to the manufacturer of the electronic ballast is large difference in the output voltage can adjust the current corresponding to the heater to obtain the voltage required for the output voltage. Actually, when the electronic ballast is higher than a certain output voltage, the switching driving circuit stops the operation for a while. Referring to FIG. 3, which is a circuit of the electronic ballast, the circuit is configured in series with the heater electrode, the switching driver, the transformer 303, the heater, and the capacitor 305. Therefore, when either of the heater electrodes of both circuits are disconnected, the switching driver blocks or adjusts the output voltage according to the feedback value. If a lot of current flows to the terminal corresponding to the heater, the output voltage of the electronic ballast will be high. 5, 7, and 8 are the same method for flowing a current corresponding to the heater, but instead of the basic drawings of FIG. 5, 508, 509, FIG. 7, 705, 706, and 805, 807 of FIG. Additional circuits such as (16-A) or (16-B) are attached. First, 16-A requires two things to flow a current corresponding to a heater, but since only one part is shown and described, it will be described. In addition, if only one side of the current corresponding to the heater is controlled, the terminal corresponding to the other heater may be attached with an element having an appropriate impedance. 1601 and 1601 'may be connected to a position for flowing a current corresponding to the heater, and at this time, although not shown in FIG. 16, a capacitor may be additionally attached so that only a high frequency current is input. A rectifier circuit 1602 and a capacitor 1603 are attached to both ends of the electrode, and are configured in series with the resistor 1604 and the transistor 1605. The resistor is not necessarily limited to a resistor, and may be connected without a resistor by shorting the 1608 according to an operation method, and may be replaced with an inductance, or may be configured in series with or in parallel with a resistor. The input terminal current corresponding to the heater electrode can be adjusted according to the bias of the transistor, and if the output voltage of the ballast is actively controlled, the output voltage of the rectifying circuit of FIGS. 5, 7 and 8 is detected to detect the transistor base input. The electronic ballast output voltage can be adjusted by adjusting the bias current. If the output voltage of the electronic ballast is high, the bias current is low. If the output voltage of the electronic ballast is low, the bias current can be flowed high to obtain a stable voltage. In addition, if the bias current does not flow, the electronic ballast intermittently outputs an output voltage.
만약, 마이컴 연산 및 제어 모듈에서 제어할 경우 스위칭 또는 전류제어 1606에 D/A 컨버터를 부착하여 마이컴 연산 및 제어 모듈 신호를 1607로 전달하여 바이어스 전류를 조절할 수 있도록 한다. 상기 마이컴 연산 및 제어 모듈에서 전자식 안정기의 출력 전압을 실시간 검출 받고, 트랜지스터에 바이어스 전류를 제어하여 전자식 안정기의 출력 전압을 일정하게 하거나 필요한 전압을 출력하게 할 수 있는 것을 제공한다. If it is controlled by the microcomputer operation and control module, the D / A converter is attached to the switching or current control 1606 to transfer the microcomputer operation and control module signal to 1607 to adjust the bias current. The microcomputer operation and control module detects the output voltage of the electronic ballast in real time and controls the bias current to the transistor so that the output voltage of the electronic ballast can be constant or output the required voltage.
도 16의 (16-B)의 경우도 상술한 (16-A)와 같은 위치에 회로를 추가로 부착하고, 히터에 대응하는 단자에 정류회로를 사용하지 않고 히터에 대응하는 전류를 흘릴 수 있는 회로 구성이다. 임피던스를 가지는 저항 또는, 인덕턴스 또는, 커패시터를 단독 또는 직, 병렬로 구성된 소자 1612와, FET 1611과 직렬로 구성하고, GATE에 바이어스 전압을 조절하여 교류에 대해 임피던스가 변화하도록 하거나 스위칭 역할을 하도록 하여 히터 전류를 조절하는 것을 제공한다. 1611'와 1612'는 FET를 스위칭 방식을 사용할 경우에 1612와 1612'의 임피던스를 다르게 하여 히터 전류를 조정할 수 있도록 하기 위한 방법도 제공한다.In the case of (16-B) of FIG. 16, a circuit can be additionally attached to the same position as (16-A) described above, and a current corresponding to the heater can be flown without using a rectifier circuit at a terminal corresponding to the heater. Circuit configuration. A resistor having an impedance, an inductance, or a capacitor is configured in series with the device 1612, which is configured alone, in series, or in parallel with the FET 1611, and adjusts the bias voltage to the gate to allow the impedance to change or switch to alternating current. To regulate the heater current. The 1611 'and 1612' also provide a way to adjust the heater current by varying the impedance of the 1612 and 1612 'when the FET is switched.
상술한 (16-A) 및 (16-B)의 회로 방식을 사용하여 히터에 대응하는 전극단자에 전류 조정을 마이컴으로 제어할 경우는 절연할 필요가 있으며, 상술한 GATE 또는, BASE에 바이어스 전류로 조정하는 방법 외에 PWM 방식으로 전류를 제어하여도 무방하다. 여기서, PWM 방식도 상기 마이컴 연산 및 제어 모듈에서 전자식 안정기의 출력 전압을 실시간 검출 받고, 상기 스위칭회로에 상기 마이컴 연산 및 제어 모듈에서 PWM 방식으로 제어하여 전자식 안정기의 출력 전압을 일정하게 하거나 필요한 전압을 출력하게 할 수 있는 것을 제공한다. (16-B)의 회로 방식에서 트랜지스터 또는, FET로 상술한 히터에 대응하는 고주파 전류를 제어하기 위한 목적이므로 교류스위칭이 가능하도록 회로를 구성하면 된다.When controlling the current adjustment by the microcomputer to the electrode terminal corresponding to the heater by using the circuit system of (16-A) and (16-B) described above, it is necessary to insulate the bias current to the above-described GATE or BASE. In addition to the control method, the current may be controlled by the PWM method. Here, the PWM method also receives the output voltage of the electronic ballast in real time in the microcomputer operation and control module, and the output voltage of the electronic ballast is constant or required voltage by controlling the switching circuit in the PWM method in the microcomputer operation and control module. Provide something that can be output. In the circuit system of (16-B), since the transistor or the FET is used to control the high frequency current corresponding to the heater described above, the circuit may be configured to enable AC switching.
본 발명은 LED 램프의 밝기를 소등에서부터 최대 밝기까지 변화할 수 있도록 하였으므로 전자식 안정기의 전압변동폭이 크게 됨에 따라 상술한 봐와 같이 히터 단자에 대응하는 전극단자에 전류를 조절하여 전자식안정기의 안정된 고주파 출력전압을 얻을 수 있도록 한 것이 특징이다.According to the present invention, the brightness of the LED lamp can be changed from extinguished to maximum brightness, so that the voltage fluctuation range of the electronic ballast increases, so as to adjust the current to the electrode terminal corresponding to the heater terminal as described above, a stable high frequency output of the electronic ballast is provided. It is characteristic that voltage can be obtained.
본 발명은 재래식 안정기, 상용전원 입력방식, 전자식안정기 모두 동작하도록 하고 있다. 여기서, 전자식안정기는 내부에 역률보상회로가 내장되어 있다. 따라서, 재래식 안정기, 상용전원 입력방식에 대해서는 도 18의 밸리빌 회로에서 1803, 1804, 1805, 1806의 부품소자를 이용하여 이미 공지된 방법으로 역률을 개선하고, 전자식안정기의 경우는 역률 개선할 필요가 없으므로 전자식안정기의 고주파 전압을 검출하여 1808의 스위칭회로를 ON하여 역률 개선회로의 기능을 상실하게 한다. 커패시터 1803, 1804가 직렬로 연결되어 있으므로 실제 커패시터 용량은 1/2로 줄어들지만 1808을 ON하게 되면 커패시터 1803 하나로 동작하는 효과를 얻을 수 있으므로 전자식안정기의 고주파 출력전압을 좀더 안정되게 평활회로를 구성할 수 있다.The present invention is to operate the conventional ballast, commercial power input method, electronic ballast. Here, the electronic ballast has a power factor correction circuit built therein. Therefore, in the conventional ballast and commercial power input method, the power factor is improved by a known method using component elements of 1803, 1804, 1805, and 1806 in the Valleyville circuit of FIG. 18, and in the case of an electronic ballast, it is necessary to improve the power factor. Since the high frequency voltage of the electronic ballast is not detected, the switching circuit of 1808 is turned on to lose the function of the power factor correction circuit. Since capacitors 1803 and 1804 are connected in series, the actual capacitor capacity is reduced to 1/2, but when 1808 is turned ON, the effect of one capacitor 1803 can be obtained.

직관형 LED 조명등에서 히터 대응 전극단자가 양쪽에 1101-1102, 1101'-1102' 또는, 501, 502에 각각 2개의 핀이 있다. 만약 501을 소켓에 끼운 상태에서 전원전압을 인가할 때 502에 누설전류로 인한 감전의 위험이 있으므로 충전부 감전보호를 하여야 한다. 도 17의 경우 1701, 1702 단자는 501에 대응하고, 1703, 1704 단자는 502에 대응할 경우 일반적 회로에서는 1718의 LED 구동회로 및 LED 모듈에 의해 부하가 형성된다. 또한, 1717 평활 커패시터는 충전시에 대해 순간적 임피던스가 낮아진다. 따라서 1101에 전류를 투입하면 1101'로 전류가 흐르게 되어 감전사고가 발생할 경우가 있다. 동일한 방법으로 1101'에 전류를 투입하면 1101로 전류가 흐르게 되어 감전사고가 발생할 수 있다. 이와 같은 문제를 해소하기 위해 본 발명에서는 1710 및 1714의 반도체 스위칭 회로를 사용하여 1717 커패시터 및 1718 부하장치로 인한 전류 흐름을 차단하도록 발명하였다. 도 17은 (-)전원 라인을 제어하도록 하였으나 (+)전원 라인을 제어하기 위한 변경은 당 분야 종사자라면 쉽게 변경이 가능할 것이다. 따라서 본 발명에서는 (-)전원 라인만 제어하는 예를 설명하기로 한다. 또한, 본 발명은 상술한 봐와 같이 전자식안정기, 자기식안정기, 상용전원 입력방식 모두 동작하도록 하고 있기 때문에 이중정류회로를 구성하고 있다.In a straight LED lamp, heater-compatible electrode terminals have two pins 1101-1102 and 1101'-1102 'or 501 and 502 on each side. If the power supply voltage is applied while the 501 is inserted into the socket, there is a risk of electric shock due to leakage current in the 502. In the case of FIG. 17, when the terminals 1701 and 1702 correspond to 501 and the terminals 1703 and 1704 correspond to 502, a load is formed by the LED driving circuit and the LED module of 1718 in a general circuit. In addition, the 1717 smoothing capacitor has a low instantaneous impedance with respect to charging. Therefore, when current is supplied to 1101, current flows to 1101 ', which may cause an electric shock. In the same way, when a current is supplied to 1101 ', a current flows to 1101, which may cause an electric shock. In order to solve this problem, the present invention uses the semiconductor switching circuits of 1710 and 1714 to block current flow due to the 1717 capacitor and the 1718 load device. Figure 17 is to control the (-) power line, but the change for controlling the (+) power line will be easily changed by those skilled in the art. Therefore, in the present invention, an example of controlling only a negative power line will be described. In the present invention, since the electronic ballast, the magnetic ballast, and the commercial power input method operate as described above, the double rectifier circuit is constructed.
먼저, 부하장치인 LED 램프가 정상동작을 위해서는 스위칭소자 1710, 1714가 도통이되어 정류소자 1705의 역방향 출력 전원 1719와 정류소자 1706의 역방향 출력 전원 1720과 단락현상을 유지해야 1717, 1718로 전원이 공급된다.First, in order for the LED lamp, which is the load device, to operate normally, the switching elements 1710 and 1714 are turned on to maintain the short circuit with the reverse output power 1719 of the rectifying device 1705 and the reverse output power 1720 of the rectifying device 1706. Supplied.
스위칭소자 1710, 1714가 동작하기 위해서는 바이어스 전압이 필요하다. 본 발명은 전자식안정기, 자기식안정기, 래피드 스타트 안정기들은 히터전류를 흘려주고 있다. 전자식안정기와 래피드 스타트 방식의 안정기는 히터전류를 흘리기 위해 히터 양단에 전압을 공급하고 있고, 자기식안정기의 경우 본 발명에서는 점등관이 동작을 하지 않도록 하고 있지만 점등관에 미세한 방전으로 인한 전류가 흐르게 된다. 따라서 상술한 안정기들은 501, 502의 히터 대응 단자를 통해 1705, 1706의 정류소자를 통해 전압이 공급되게 된다. 상기 전압은 1710, 1714 스위칭 소자의 FET에 바이어스가 입력되어 DRAIN과 SOURCE 사이에 단락효과를 유지하여 1719, 1720의 역방향(-) 전원 라인을 단락현상을 유지하여 1717 정류용 콘덴서를 충전하고, 1718 부하장치의 LED 구동회로 및 LED 모듈을 점등할 수 있도록 한다. 이때 히터 대응 단자에 히터전원 외에 고전압 전력이 501, 502 전극단자를 통해 함께 공급됨을 잘 알고 있을 것이다.A bias voltage is required for the switching elements 1710 and 1714 to operate. In the present invention, the electronic ballast, the magnetic ballast, and the rapid start ballasts pass a heater current. The electronic ballast and the rapid start type ballast supply voltage to both ends of the heater to flow the heater current, and in the case of the magnetic ballast, the lighting tube does not operate in the present invention, but a current due to the minute discharge flows through the lighting tube. Therefore, the above ballasts are supplied with voltage through the rectifiers of 1705 and 1706 through the heater corresponding terminals of 501 and 502. The voltage is charged to the FET of the 1710, 1714 switching element to maintain the short circuit effect between DRAIN and SOURCE to maintain the short circuit of the 1719, 1720 reverse (-) power line to charge the 1717 rectifier capacitor, 1718 The LED driving circuit and LED module of the load device can be turned on. At this time, it will be appreciated that high voltage power is supplied to the corresponding heater terminal through the 501 and 502 electrode terminals.
만약, 히터 대응 전극단자 501에만 전기가 공급되었다면 스위칭 소자 1710만 스위칭 소자의 FET에 바이어스가 입력되어 DRAIN과 SOURCE 사이에 단락효과를 유지하고, 1714 스위칭 소자의 FET에 바이어스가 공급되지 않으므로 DRAIN과 SOURCE 사이에 단선효과가 발생하여 히터 대응 전극단자 502로 누설전류가 차단된다. 만약, 히터 대응 전극단자 502에만 전기가 공급되었다면 스위칭 소자 1714만 스위칭 소자의 FET에 바이어스가 입력되어 DRAIN과 SOURCE 사이에 단락효과를 유지하고, 1710 스위칭 소자의 FET에 바이어스가 공급되지 않으므로 DRAIN과 SOURCE 사이에 단선효과가 발생하여 히터 대응 전극단자 501로 누설전류가 차단된다. 여기서, 1715 및 1716의 다이오드는 히터 대응 전극단자 501, 502중 어느 한쪽에만 전원이 공급되었다면 해당 스위칭 소자만 바이어스가 공급되도록 하기 위한 역전압 방지를 위한 수단이다.If only the heater terminal 501 is supplied with electricity, a bias is inputted to the FET of the switching element 1710 to maintain the short-circuit effect between DRAIN and SOURCE, and since the bias is not supplied to the FET of the 1714 switching element, DRAIN and SOURCE The disconnection effect is generated between them, and the leakage current is cut off by the electrode terminal 502 corresponding to the heater. If electricity is supplied only to the heater corresponding electrode terminal 502, a bias is inputted to the FET of the switching element only 1714 to maintain a short-circuit effect between DRAIN and SOURCE, and the bias is not supplied to the FET of the 1710 switching element. A disconnection effect is generated between the terminals so that the leakage current is cut off by the electrode terminal 501 corresponding to the heater. Here, the diodes of 1715 and 1716 are means for preventing reverse voltage so that only the switching element is biased if power is supplied to only one of the heater corresponding electrode terminals 501 and 502.
상술한 봐와 같이 1705, 1706 정류회로와 1717 커패시터 및 1718 부하장치인 LED 구동회로 및 LED 모듈을 정류회로의 전원과 단선 또는, 단락할 수 있는 1710, 1714와 같이 반도체 스위칭회로를 구성하고, 상기 스위칭회로는 501, 502 단자로부터 전원공급을 검출하고, 1710, 1714 스위칭 소자를 직렬구성하여 전원공급이 양쪽 단자 모두 검출되었을 때만 1717 커패시터 및 1718 부하장치인 LED 구동회로 및 LED 모듈을 정류회로의 전원과 단락하도록 하여 정상동작하게 하고, 만약, 501, 502 단자로부터 전원공급이 어떤 쪽이든 한쪽만 공급될 경우는 1710, 1714 둘 중 하나의 스위칭회로가 OFF되어 정류회로의 1717 커패시터 및 1718 부하장치인 LED 구동회로 및 LED 모듈을 정류회로의 전원과 단선 되도록 하여 501, 502의 전극단자 중에 전원을 공급하지 않는 단자 쪽으로 누설전류가 흐르지 못하게 하여 감전사고를 예방하는 것을 특징으로 한다.As described above, the LED driving circuit and the LED module, which are the 1705 and 1706 rectifier circuit, the 1717 capacitor, and the 1718 load device, constitute a semiconductor switching circuit such as 1710 and 1714 that can disconnect or short-circuit the power supply of the rectifier circuit. The switching circuit detects the power supply from the terminals 501 and 502, and configures the 1710 and 1714 switching elements in series so that the LED driving circuit and the LED module, which are the 1717 capacitor and the 1718 load device, are connected to the rectifier circuit only when the power supply is detected at both terminals. If the power supply is supplied from either side of the 501 or 502 terminal, one of the switching circuits of 1710 and 1714 is turned off so that the 1717 capacitor and the 1718 load device of the rectifier circuit are turned off. Leakage current flows to terminal that does not supply power among electrode terminals of 501 and 502 by disconnecting driving circuit and LED module from power of rectifier circuit. Let the features that prevent electrical shock.
통상적으로 인덕턴스에 직류전압을 가하면 초기에는 전류가 작게 흐르다가 일정 시간이 흐르면 전류가 크게 흐르게 되고, 커패시터는 이와 반대로 전류가 흐르게 된다. 이와 같은 부품 소자의 특성을 이용하여 상술한 스위칭 드라이브 단에서 인덕턴스와 커패시터를 직렬로 구성함에 따라 FET의 경우 DRAIN과 SOURCE, 트랜지스터의 경우는 COLLECTOR와 EMITTER간에 전압강하가 0V에 가깝게 떨어지므로 스위칭 소자에 열화 현상을 없앨 수 있고 만약의 경우 푸시풀 스위칭 소자 2개 중 1개가 파손되어 단락되었다 하더라도 커패시터 1206에 의해 +B전원의 단락현상은 막을 수 있는 것이 특징이다.In general, when a DC voltage is applied to the inductance, the current initially flows small, but when a predetermined time passes, the current flows large, and the capacitor flows in reverse. As the inductance and the capacitor are configured in series in the switching drive stage using the characteristics of such a component element, the voltage drop between the drain and source of the FET and the collector and the emitter of the transistor falls close to 0 V in the switching element. The deterioration phenomenon can be eliminated, and in the case of one of the two push-pull switching elements, the capacitor 1206 prevents the short circuit of the + B power supply even if it is shorted.

To the secondary DC voltage through the rectifier and the smoothing capacitor, connect the DC voltage to the LED lamp module and the current detection resistor in series, and transfer the current flowing through the lamp to the PWM driving module.
