본 발명은 LED 센서등 구동회로에 관한 것으로서, 좀 더 상세히는 건물의 현관 등에 설치되는 LED 센서등의 오동작을 방지하고 역률 개선 및 프리볼트로 사용할 수 있도록 된 새로운 구조의 LED 센서등 구동회로에 관한 것이다.
The present invention relates to a driving circuit of the LED sensor lamp, and more particularly to a driving circuit of the LED sensor lamp of a new structure that can be used to prevent malfunction of the LED sensor lamp installed in the porch of the building, such as improving the power factor and free bolt. will be.

건물의 현관이나 복도 등에 설치되어 사람이 존재할 경우에만 이를 검출하여 동작하도록 된 센서등이 널리 사용되고 있다. 이러한 센서등에는 대체로 주간과 야간을 구별하기 위한 조도센서와, 인체로부터 발산되는 적외선센서가 구비되어, 주변이 어두운 경우나 야간에만 작동되면서, 아울러 사람이 지나갈 때만 이를 검출하여 작동되도록 구성된다. 종래에는 이러한 센서등에 사용되는 램프가 주로 백열등이나 형광등이 사용되었다.Sensors installed in the entrance or corridor of a building to detect and operate only when a person exists are widely used. Such a sensor is generally provided with an illumination sensor for distinguishing day and night, and an infrared sensor emitted from the human body, and is configured to operate by detecting only when a person passes by while operating only in the dark or at night. Conventionally, incandescent lamps or fluorescent lamps have been mainly used as lamps for such sensors.

도 1은 종래에 사용되는 이러한 센서등용 구동회로를 보여주는데, 도시된 바와 같이, 100V 또는 220V의 AC전원이 전원입력단으로 입력되어 정류부(2)와 정전압부(4)를 거쳐서 센서등 구동부(10) 네부의 복수개의 OP앰프가 내장된 증폭부(11)와 주변회로에 전원을 공급함과 동시에 트라이액(18)을 거쳐서 스위칭되는 전력을 전원출력단을 통해 도시안된 LED램프 쪽으로 출력한다. 한편, 이러한 센서등 구동부(10)에는 센서등의 작동조건이 되는 주변의 조도를 검출하기 위한 조도검출부(12)와, 사람의 존재여부를 검출하기 위해 인체에서 발산되는 적외선을 감지하는 적외선선서와 같은 인체감지센서(14), 센서등의 점등 후 소정의 설정시간 후에 센서등을 소등하기 위한 타이머부(15) 및 센서등의 작동시의 주변의 밝기 등의 작동모드를 설정하기 위한 모드선택스위치부(16)를 포함한다.Figure 1 shows such a driving circuit for a sensor lamp, which is conventionally used, as shown, 100V or 220V AC power is input to the power input terminal through the rectifying unit 2 and the constant voltage unit 4, the driving unit for the sensor lamp 10 While supplying power to the amplifier 11 and the peripheral circuit with a plurality of four OP amplifier is built-in and outputs the power switched through the triac 18 to the LED lamp not shown through the power output stage. On the other hand, such a sensor driving unit 10 has an illumination intensity detection unit 12 for detecting the ambient illumination that is an operating condition such as a sensor, and an infrared oath for detecting infrared rays emitted from the human body to detect the presence of a person; Mode selection switch for setting the operation mode such as the brightness of the surroundings when the sensor body 14, the timer unit 15 for turning off the sensor lamp after a predetermined set time after the lighting of the sensor lamp, and the sensor lamp are operated. Part 16 is included.

그런데, 종래의 센서등 회로는 외부의 AC전원이 정류부(2)와 정전압부(4)를 거쳐서 직접 증폭부(11)를 포함하는 센서등 구동부(10)로 직접 입력되므로, 외부의 부하변동에 따라 인가되는 AC전원의 변동이 적지 않아서, 구동부(10)가 외부의 노이즈나 서지전압 등에 의해 영향을 많이 받게 된다. 그런데 센서등의 램프가 백열등이나 형광등인 경우에는 상대적으로 고전력에 의해 작동되므로 센서등의 작동에 큰 지장을 주지 않으나, 센서등 램프가 LED 램프와 같이 저전력 저전압하에 구동되는 경우에는 미세한 전압변동과 같은 노이즈에 의해서도 구동부(10)가 오동작을 일으키게 되고, 센서등의 점등이 필요한 상황에서 점등이 되지 않거나, 역으로 센서등의 점등이 필요없는 상황에서도 센서등이 점등되는 오동작과 역률이 저하되어 불필요한 전력을 낭비하는 등의 문제점이 있었다. 또한, 종래의 센서등은 사용전압이 100V 또는 220V로 세팅되어 있어서, 건물의 사용전압에 따라 센서등의 전압을 구별하여 구입 및 설치해야 하는 번거로움이 있었다.
By the way, in the conventional sensor lamp circuit, since the external AC power is directly input to the sensor lamp driving unit 10 including the amplifying unit 11 directly through the rectifying unit 2 and the constant voltage unit 4, the external load fluctuations Accordingly, there is little variation in the AC power applied, so that the driving unit 10 is affected by external noise, surge voltage, and the like. However, when the lamp of the sensor lamp is incandescent or fluorescent lamp, it is operated by relatively high power, so it does not affect the operation of the sensor lamp. However, when the lamp of the sensor lamp is driven under low power and low voltage like LED lamps, there is a slight voltage fluctuation. The driving unit 10 also malfunctions due to noise, and in the situation where the lighting of the sensor is not necessary, the lighting is not turned on, or conversely, the malfunction of the sensor is turned on even when the lighting of the sensor is not needed, and the power factor is lowered. There was a problem such as wasting. In addition, the conventional sensor lamp is set to a voltage of 100V or 220V, there is a hassle to purchase and install the voltage of the sensor lamp according to the voltage of the building.

본 발명은 전술한 바와 같은 종래의 LED 센서등의 작동상의 문제점에 착안하여 제안된 것으로서, 본 발명은 LED 센서등이 노이즈나 기타 외부의 전압변동 등에 의해 영향을 받지 않고 신뢰성있게 동작할 수 있고 아울러 역율의 저하를 방지할 수 있어서 에너지효율도 우수하고, 프리볼트 기능이 있어서 사용이 편리한 새로운 구조의 LED 센서등 구동회로를 제공하고자 하는 것이다.
The present invention has been proposed in view of the operational problems of the conventional LED sensor, as described above, the present invention can be reliably operated without being affected by noise or other external voltage fluctuations, etc. It is to provide a driving circuit with a new structure such as LED sensor, which can prevent the fall of the power factor, which is excellent in energy efficiency, and has a free bolt function, which is easy to use.

본 발명의 한 특징에 따르면, 외부의 교류전원이 입력되는 AC입력단에 연결되는 전원공급부(PS)와, 이 전원공급부(PS)의 후단에 연결되며 증폭부(11)를 포함하는 구동부(10)와, 이 증폭부(11)에 연결되며 주변의 조도를 검출하는 조도검출부(12)와, 상기 증폭부(11)에 연결되며 인체의 존재 여부를 검출하는 인체감지센서(14)와, 센서등을 소정시간 동안 작동시키는 타이머부(15)와, 상기 증폭부(11)에 게이트단이 연결되는 트라이액(18)과, 이 트라이액(18)에 의해 스위칭되며 LED 센서등이 연결되는 전원출력단을 포함하는 LED 센서등 구동회로에 있어서, 상기 전원공급부(PS)는 정류부(23)와, 이 정류부(23)의 후단 양측에 각각 접속되는 공진부(24) 및 전압조정기(25)와, 이 공진부(24) 및 전압조정기(25)의 각각의 후단에 일차측이 연결되는 트랜스부(26)와, 상기 트랜스부(26)의 이차측에 순차연결되는 정류부(28)와 정전압부(29)로 이루어진 것을 특징으로 하는 LED 센서등 구동회로가 제공된다.
According to one feature of the invention, the power supply unit PS is connected to an AC input terminal to which an external AC power is input, and the driving unit 10 is connected to the rear end of the power supply unit PS and includes an amplification unit 11. And an illuminance detection unit 12 connected to the amplification unit 11 and detecting peripheral illumination, a human body sensor 14 connected to the amplifying unit 11 and detecting the presence of a human body, a sensor, and the like. Timer unit 15 for operating a predetermined time, the triac 18, the gate terminal is connected to the amplification unit 11, and the power output stage is switched by the triac 18, the LED sensor, etc. In a driving circuit such as an LED sensor, the power supply unit PS includes a rectifier 23, a resonator 24 and a voltage regulator 25 connected to both rear ends of the rectifier 23, respectively. A transformer section 26 having a primary side connected to the rear ends of the resonator section 24 and the voltage regulator 25; and the transformer section 26; An LED sensor lamp driving circuit is provided, comprising a rectifying unit 28 and a constant voltage unit 29 sequentially connected to the secondary side of the.

본 발명의 다른 특징에 따르면, 상기 정류부(23)의 전단에는 서지보호용 배리스터(21)와 EMI필터(22)가 접속된 것을 특징으로 하는 LED 센서등 구동회로가 제공된다.
According to another feature of the present invention, an LED sensor lamp driving circuit is provided at the front end of the rectifying unit 23 to which the surge protection varistor 21 and the EMI filter 22 are connected.

본 발명의 다른 특징에 따르면, 상기 전압조정기(25) 내에는 프리볼트회로가 내장된 것을 특징으로 하는 LED 센서등 구동회로가 제공된다.
According to another feature of the invention, the voltage regulator 25 is provided with a driving circuit, such as an LED sensor, characterized in that the pre-volt circuit is embedded.

본 발명에 따르면, 종래의 이러한 센서등 회로와 달리 외부의 AC전원이 정류부(2)와 정전압부(4)를 거쳐서 직접 증폭부(11)를 포함하는 센서등 구동부(10)로 직접 입력되지 않고, 일차로 정류부(23)를 거친 후 공진부(24)와 전압조정기(25)를 통해서 트랜스부(26)의 일차측으로 입력되므로, 입력전원에 포함된 노이즈나 써지전압과 같은 불필요한 전압변동이 트랜스부(26)의 이차측에 전달되지 않으므로, 구동부(10)의 조도센서(12)나 인체감지센서(14) 등이 AC입력의 노이즈에 의해 오동작되는 것이 방지되므로, LED 램프가 정확하게 작동될 수 있고 결과적으로 역률의 저하를 방지할 수 있다. According to the present invention, unlike the conventional circuit of such a sensor lamp, the external AC power is not directly input to the sensor lamp driving unit 10 including the amplification unit 11 directly through the rectifying unit 2 and the constant voltage unit (4). After passing through the rectifier 23 firstly, the resonator 24 and the voltage regulator 25 are input to the primary side of the transformer 26, so that unnecessary voltage fluctuations such as noise or surge voltage included in the input power supply are transmitted. Since it is not transmitted to the secondary side of the unit 26, since the illuminance sensor 12, the human body sensor 14, etc. of the driving unit 10 are prevented from malfunctioning by the noise of the AC input, the LED lamp can be operated correctly. As a result, the fall of the power factor can be prevented.

또한, 정류부(23)의 전단에 서지보호용 배리스터(21)와 EMI필터(22)가 순차접속되므로, 서지전압을 차단하고 입력되는 교류전원에 포함된 고주파 노이즈를 제거할 수 있어서, 구동부(10)의 오동작을 방지하여 LED 센서등의 역률개선과 불필요한 전력낭비를 억제할 수 있다. 또한, 전압조정기(25) 내에는 프리볼트 회로가 내장되어 사용되는 전압이 100V 또는 220V인가의 구별없이 센서등을 사용할 수 있어서 편리하다.
In addition, since the surge protection varistor 21 and the EMI filter 22 are sequentially connected to the front end of the rectifying section 23, the surge voltage can be interrupted and the high frequency noise included in the input AC power source can be removed, thereby driving the drive unit 10. By preventing malfunctions, power factor improvement and unnecessary power consumption of LED sensors can be suppressed. In the voltage regulator 25, a sensor or the like can be used regardless of whether the voltage used in the prevolt circuit is built in 100V or 220V.

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. 도 2는 본 발명의 일 실시예의 회로도로서, 90V~260V의 교류전원이 입력되는 AC입력단에 전원공급부(PS)가 연결되고, 이 전원공급부(PS)의 후단에는 증폭부(11)를 포함하며 LED 센서등을 구동하는 구동부(10)가 접속된다.Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 2 is a circuit diagram of an embodiment of the present invention, in which a power supply unit PS is connected to an AC input terminal to which an AC power source of 90V to 260V is input, and an amplifier 11 is included at a rear end of the power supply unit PS. The drive part 10 which drives an LED sensor light is connected.

상기 구동부(10)는 종래의 일반적인 센서등 구동회로와 유사하게, 센서등이 설치된 주변의 조도를 검출하는 광도전소자로 된 조도검출부(12)와, 센서등이 설치된 위치에서 인체가 발하는 적외선 등을 검출하여 사람이 존재하는지 여부를 검출하는 인체감지센서(14), 점등된 센서등이 소정 시간 동안 점등상태를 유지한 후에 소등되도록 센서등의 작동시간을 지연하여 스위칭하는 타이머부(18), 그리고 센서등의 점등시의 주변의 밝기 등의 작동모드를 설정하기 위한 모드선택스위치부(16)를 포함한다.The driving unit 10 is similar to a driving circuit of a conventional sensor lamp, and the like, and an illuminance detector 12 made of a photoconductive element for detecting the illuminance around the sensor lamp is installed, and an infrared light emitted by a human body at a position where a sensor lamp is installed. A human body detecting sensor 14 for detecting whether a person exists or not, a timer unit 18 for delaying and switching the operation time of the sensor light so that the light is turned off after the lighted sensor light maintains a lighting state for a predetermined time; And a mode selection switch section 16 for setting an operation mode such as brightness of the surroundings when the sensor lamp is turned on.

한편, 본 발명의 전원공급부(PS)는 상용교류전원이 인가되는 전원입력단에 연결되는 서지보호용 배리스터(21)와, 이 서지보호용 배리스터(21)의 후단에 연결되며 코일을 포함하는 EMI필터(22)가 순차 연결되어 입력되는 교류전원에 포함된 서지전압이나 고주파 노이즈를 차단 제거한다.On the other hand, the power supply unit (PS) of the present invention is connected to the surge input varistor 21 is connected to the power input terminal to which the commercial AC power is applied, the EMI filter 22 is connected to the rear end of the surge protection varistor 21 and comprises a coil ) To block and remove surge voltage or high frequency noise included in AC power input.

그리고 이 EMI필터(22)의 후단에는 브리지회로로 된 정류부(23)가 접속되어 교류를 직류로 변환시키고, 이 정류부(23)의 양 출력측에는 공진부(24)와 전압조정기(25)가 연결되고, 이들 공진부(24)의 후단 코일은 트랜스(26)의 일차측 코일을 형성하고, 전압조정기(25)의 후단에는 트랜스(26)의 또 다른 일차측 코일이 접속된다. 상기 전압조정기(25)에는 프리볼트회로가 내장된다.A rectifier 23 formed of a bridge circuit is connected to the rear end of the EMI filter 22 to convert AC into direct current, and the resonator 24 and the voltage regulator 25 are connected to both output sides of the rectifier 23. The rear end coils of these resonators 24 form a primary side coil of the transformer 26, and another primary side coil of the transformer 26 is connected to the rear end of the voltage regulator 25. The voltage regulator 25 has a built-in free volt circuit.

트랜스부(26)의 2차측에 유기된 전압강하된 교류는 다시 정류부(28)를 거쳐서 직류로 변환된 후 정전압부(29)를 통해 일정한 전압레벨의 직류로 되어 그 후단에 접속되는 전술한 바와 같은 LED 센서등용 구동부(10)에 구동전원을 인가한다. 이상에서 설명한 본 발명에 따르면, 입력되는 AC전원에 포함되는 노이즈나 서지전압 등이, 직접 센서등 구동부(10)로 인가되지 않고, 일차로 정류부(23)를 거친 후에 공진부(24)와 전압조정기(25)를 통해서 교류로 변환된 후에 트랜스부(26)를 거쳐서 구동제어부(10)로 인가되므로, 이 입력전원에 포함된 노이즈나 서지 등의 이상 전압이 트랜스부(26)의 2차측으로 전달되지 않으므로, 구동부(10)가 트라이액(18)을 트리거하여 LED 센서등을 구동할 때, 노이즈나 서지 전압 등에 의해 오작동되는 일이 방지되므로, 그만큼 노이즈에 민감한 LED 센서등의 오작동을 효과적으로 방지하여, 신뢰성있는 센서등의 작동을 달성하고, 불필요한 센서등의 작동에 의한 전력낭비 등을 방지하여 역률개선에 기여할 수 있다. 아울러 프리볼트기능이 구비되어 사용전압에 따라 센서등을 구별할 필요가 없어서 편리하다.
As described above, the voltage-dropped alternating current induced on the secondary side of the transformer unit 26 is converted into direct current through the rectifying unit 28 and then connected to the rear end of the constant voltage unit 29 through a constant voltage level. The driving power is applied to the driving unit 10 for the same LED sensor. According to the present invention described above, the noise and surge voltage included in the input AC power is not directly applied to the drive unit 10 such as the sensor, but primarily passes through the rectifier 23 and then the resonator 24 and the voltage. Since it is converted into alternating current through the regulator 25 and then applied to the drive control unit 10 via the transformer unit 26, abnormal voltages such as noise and surge included in this input power supply are transferred to the secondary side of the transformer unit 26. Since it is not transmitted, when the driving unit 10 triggers the triac 18 to drive the LED sensor, malfunction is prevented by noise or surge voltage, and thus, malfunction of the LED sensor, which is sensitive to noise, is effectively prevented. Therefore, it is possible to achieve operation of a reliable sensor and the like, and to prevent power waste due to unnecessary operation of the sensor and the like, thereby contributing to power factor improvement. In addition, the free-bolt function is convenient because it does not need to distinguish the sensor according to the voltage used.
