평상시에는 비상교류전원(ACN)이 공급되지 않고, 상용교류전원(ACN) AC 220V만이 공급되고, 정전 등과 같은 비상시에는 상용교류전원(ACN)이 공급되지 않고, 비상교류전원(ACN)인 AC 220V가 공급된다.(ACN) AC 220V is supplied without supplying the emergency AC power supply (ACN), and the commercial AC power supply (ACN) is not supplied in case of emergency such as power failure, .

또한 정전 등 이외의 비상시에는 상용교류전원(ACN)과 비상교류전원(ACN)이 동시에 공급될 수도 있다.Also, in case of an emergency other than a power failure, the commercial AC power supply (ACN) and the emergency AC power supply (ACN) may be supplied at the same time.

먼저, 평상시인 경우의 본 발명의 비상등 겸용 센서등 제어장치의 동작은 다음과 같다.First, the operation of the control device such as the emergency light sensor of the present invention in the normal case is as follows.

상용교류전원(ACN)의 공급에 따라 제1전파정류부(10)는 상용교류전원(ACN)을 전파정류하여 출력노드(NO)로 상용전파정류신호(FH1)를 출력하고, 제2전파정류부(20)는 출력노드(NO)로 비상전파정류신호(FH2)를 출력하지 못한다.The first full-wave rectification section 10 performs full-wave rectification of the commercial AC power source ACN to output the commercial full-wave rectification signal FH1 to the output node NO according to the supply of the commercial AC power source ACN, 20 can not output the emergency full-wave rectification signal FH2 to the output node NO.

제1필터부(30)는 출력노드(NO)로 출력되는 상용전파정류신호(FH1)를 수신하여 고전압을 갖는 제1직류전압(V1)을 출력한다.The first filter unit 30 receives the commercial full-wave rectified signal FH1 output to the output node NO and outputs a first DC voltage V1 having a high voltage.

직류전압발생부(40)는 SMPS(Switching Mode Power Supply)로 구성되어, 제1직류전압(V1)을 수신하여 제1직류전압(V1) 보다 낮은 직류전압인 대략 36V를 갖는 조명등(100)을 점등시키기 위한 조명공급전압(Vlp)을 출력한다.The DC voltage generating unit 40 is composed of a Switching Mode Power Supply (SMPS), and receives the first DC voltage V1 to generate a DC voltage Vd which is lower than the first DC voltage V1 And outputs an illumination supply voltage Vlp for lighting.

정전압발생부(50)는 36V의 조명공급전압(Vlp)을 수신하여 조명공급전압(Vlp) 보다 낮은 5V의 구동전압(Vd)을 출력하며, 구동전압(Vd)은 인체감지센서(60)와 센서제어부(80)의 공급전압으로 사용되어, 인체감지센서(60)와 센서제어부(80)를 동작시키게 된다.The constant voltage generating unit 50 receives the illumination supply voltage Vlp of 36V and outputs a drive voltage Vd of 5V lower than the illumination supply voltage Vlp and the drive voltage Vd is supplied to the human body detection sensor 60 Is used as a supply voltage of the sensor control unit 80 to operate the human body sensor 60 and the sensor control unit 80. [

인체감지센서(60)는 인체의 움직임이 있으면 활성화된 인체감지신호(SEN)를 출력한다.The human body detection sensor 60 outputs an activated human body detection signal SEN when there is a movement of the human body.

비상전원감지부(70)는 비상교류전원(ACN)이 공급되지 않으므로, 제2필터부(71)의 출력인 제2직류전압(V2)이 발생되지 않으므로, 포토커플러(73)의 포토다이오드(PD)에는 전류가 발생되지 않아 포토트랜지스터(PTR)는 오프되고, 이로 인해 구동전압(Vd)에 연결된 저항(R)에 의해 제어신호(SC)는 하이논리값을 가지며, 인버터(75)를 통해 비상전원감지신호(EC)는 비활성화된 로우논리값을 갖게 된다.Since the emergency DC power source ACN is not supplied to the emergency power detecting unit 70 and the second DC voltage V2 which is the output of the second filter unit 71 is not generated, the photodiode of the photocoupler 73 The phototransistor PTR is turned off so that the control signal SC has a high logic value due to the resistor R connected to the driving voltage Vd and is supplied through the inverter 75 The emergency power detection signal EC becomes inactive low logic value.

센서제어부(80)는 비상전원감지신호(EC)와 인체감지신호(SEN)를 수신받아, 비상전원감지부(70)로부터 출력되는 비활성화된 비상전원감지신호(EC)에 의해 인체감지신호(SEN)에 따라 인체감지신호(SEN)가 활성화되면 사용자에 의해 설정된 기준시간인 일정시간 동안 활성화된 점등구동제어신호(SWC)를 출력하고, 활성화된 점등구동제어신호(SWC)에 의해 구동스위칭부(90)는 조명등(100)으로 조명공급전압(Vlp)을 출력하여 조명등(100)을 기준시간 동안 점등시킨 후 점등구동제어신호(SWC)가 비활성화되면 조명등(100)을 소등시킨다.The sensor control unit 80 receives the emergency power detection signal EC and the human body detection signal SEN and receives the human body detection signal SEN And outputs the activated lighting control signal SWC for a predetermined time which is the reference time set by the user when the human body detection signal SEN is activated in response to the activation control signal SWC, 90 outputs the illumination supply voltage Vlp to the illumination lamp 100 to turn on the illumination lamp 100 for the reference time and turns off the illumination lamp 100 when the illumination control signal SWC is inactivated.

즉, 비상교류전원(ACN)이 공급되지 않고, 상용교류전원(ACN) AC 220V만이 공급되는 평상시에는 인체감지센서(60)의 인체의 움직임이 감지될 때에만 조명등(100)이 점등되도록 하여 조명등(100)은 센서등으로 동작하게 된다.That is, when the emergency AC power source ACN is not supplied and only the commercial AC power source ACN 220V is supplied, only when the human body movement of the human body detection sensor 60 is detected, the light 100 is turned on, (100) operates with a sensor or the like.

정전 등과 같은 비상시인 경우에는 상용교류전원(ACN)의 공급은 중단되고, 오직 비상교류전원(ACN)인 AC 220V가 공급되므로, 제1전파정류부(10)는 출력노드(NO)로 상용전파정류신호(FH1)를 출력하지 못하고, 제2전파정류부(20)에 의해 출력노드(NO)는 비상전파정류신호(FH2)를 출력한다.The supply of the commercial AC power is stopped and only the AC 220V of the emergency AC power supply ACN is supplied so that the first full-wave rectification part 10 is switched to the output node NO, The second full-wave rectifier 20 outputs the signal FH1 and the output node NO outputs the emergency full-wave rectified signal FH2.

제1필터부(30)는 출력노드(NO)로 출력되는 비상전파정류신호(FH2)를 수신하여 고전압을 갖는 제1직류전압(V1)을 출력하고, 직류전압발생부(40)는 제1직류전압(V1) 보다 낮은 조명공급전압(Vlp)을 출력하고, 정전압발생부(50)는 5V의 구동전압(Vd)을 출력한다.The first filter unit 30 receives the emergency full wave rectification signal FH2 output to the output node NO and outputs a first DC voltage V1 having a high voltage, And outputs the illumination supply voltage Vlp lower than the direct current voltage V1 and the constant voltage generating unit 50 outputs the drive voltage Vd of 5V.

제2필터부(71)는 비상교류전원(ACN)의 공급에 따라 제2전파정류부(20)에 의해 출력노드(NO)로 출력되는 비상전파정류신호(FH2)를 수신받아 비상전파정류신호(FH2)를 필터링하여 고전압인 제2직류전압(V2)을 출력하고, 제2직류전압(V2)에 의해 포토커플러(73)의 포토다이오드(PD)는 애노드로부터 캐소드로 전류가 흐르고 이로 인해 포토트랜지스터(PTR)는 온되어, 제어신호(SC)는 접지신호(Vs)인 로우논리값을 가지며, 인버터(75)를 통해 비상전원감지부(70)는 활성화된 비상전원감지신호(EC)를 출력한다.The second filter unit 71 receives the emergency full wave rectification signal FH2 output to the output node NO by the second full wave rectification unit 20 according to the supply of the emergency AC power ACN, The photodiode PD of the photocoupler 73 is supplied with the current from the anode to the cathode by the second direct current voltage V2 to thereby output the second direct current voltage V2, The control signal SC has a low logic value which is the ground signal Vs and the emergency power detection unit 70 outputs the activated emergency power detection signal EC via the inverter 75 do.

센서제어부(80)는 활성화된 비상전원감지신호(EC)에 의해 인체감지신호(SEN)와 상관없이 항상 하이논리값을 갖는 활성화된 점등구동제어신호(SWC)를 출력하고, 활성화된 점등구동제어신호(SWC)에 의해 구동스위칭부(90)는 조명등(100)으로 조명공급전압(Vlp)을 출력하여 비상시가 해제될때까지 즉, 비상교류전원(ACN)의 공급이 중단되어 비상전원감지신호(EC)가 비활성화될때까지 조명등(100)을 계속해서 점등시킨다. The sensor control unit 80 outputs an activated lightening drive control signal SWC always having a high logic value regardless of the human body detection signal SEN by the activated emergency power detection signal EC, The drive switching unit 90 outputs the illumination supply voltage Vlp to the illumination lamp 100 by the signal SWC to stop the supply of the emergency AC power ACN until the emergency state is released, EC) is deactivated, the illumination lamp 100 is continuously turned on.

또한, 정전시 이외의 비상시인 경우, 즉 상용교류전원(ACN)과 비상교류전원(ACN)이 동시에 공급되는 경우에는 출력노드(NO)는 제1전파정류부(10)로부터 출력되는 상용전파정류신호(FH1)와 제2전파정류부(20)로부터 출력되는 비상전파정류신호(FH2)를 가지게 되나, 상용전파정류신호(FH1)와 비상전파정류신호(FH2)는 동일한 전압이므로, 제1필터부(30)는 출력노드(NO)로 출력되는 상용전파정류신호(FH1)또는 비상전파정류신호(FH2)들 중 아무 신호나 수신하여 제1직류전압(V1)을 출력한다.When the commercial AC power supply ACN and the emergency AC power supply ACN are supplied at the same time, the output node NO is switched from the commercial full-wave rectification signal 10 outputted from the first full- Since the commercial full-wave rectification signal FH1 and the emergency full-wave rectification signal FH2 have the same voltage, the first full-wave rectification signal FH1 and the second full-wave rectification signal FH2 output from the second full- 30 receives the commercial full-wave rectification signal FH1 or the emergency full-wave rectification signal FH2 output to the output node NO and outputs the first DC voltage V1.

[

센서제어부(80)는 활성화된 비상전원감지신호(EC)에 의해 인체감지신호(SEN)와 상관없이 항상 하이논리값을 갖는 활성화된 점등구동제어신호(SWC)를 출력하여 비상전원감지신호(EC)가 비활성화될때까지 조명등(100)을 계속해서 점등시킨다. The sensor control unit 80 outputs an activated lightening drive control signal SWC always having a high logic value regardless of the human body detection signal SEN by the activated emergency power detection signal EC to generate an emergency power detection signal EC The lighting lamp 100 is continuously turned on until it is inactivated.

즉, 비상시인 경우, 비상교류전원(ACN)이 공급되면, 상용교류전원(ACN)이 공급되거나 인체감지센서(60)의 인체의 움직임의 감지 여부와 상관없이 비상교류전원(ACN)의 공급이 중단될때까지 조명등(100)을 계속해서 점등시켜주어, 조명등(100)을 비상등으로 동작하게 된다.That is, in case of an emergency, when the emergency AC power source ACN is supplied, the supply of the AC AC power source ACN, regardless of whether the commercial AC power source ACN is supplied or the human body movement of the human body detection sensor 60 is detected, The illumination lamp 100 is continuously turned on until it is stopped, and the illumination lamp 100 operates as an emergency light.
