비상전원을 포함하는 LED 디밍 센서등{LED DIMMING SENSOR LIGHT INCUDING EMERGENCY POWER LINE}LED dimming sensor light including emergency power {LED DIMMING SENSOR LIGHT INCUDING EMERGENCY POWER LINE}

본 발명은 상시 전원이나 비상전원이 공급되는 조명장치에서 디밍기능을 가지는 LED 디밍센서등에 관한 것이다. The present invention relates to an LED dimming sensor or the like having a dimming function in a lighting device that is always supplied with power or emergency power.

센서등은 사람의 움직임에 따라 자동으로 LED램프를 켜고 끄는 조명장치로서,움직임이 지속되는 동안 자동으로 연장될 수 있다.이러한 센서등은 공통현관,복도,화장실,지하 주차장등에서 매우 유용하게 사용되고 있는 실정이다.The sensor light is a lighting device that automatically turns on and off the LED lamp according to the movement of a person, and can be automatically extended while the movement continues.These sensor lights are very useful in common entrances, corridors, toilets, underground parking lots, etc. This is true.

위와 같은 LED센서등은 아파트, 대단위 사무 빌딩 등과 같은 집합건물의 공통현관, 복도,비상계단,출입문의 천정 등에 설치되는 것이 일반적이어서 사용자가 수동으로 전원 스위치를 온/오프 하지 않아도 됨으로써 사용이 편리하고 ,사람의 움직임이 감지될 때에만 점등 후 일정시간 후에 자동으로 오프 됨으로써 불필요한 전력 낭비를 방지할 수 있다.The above LED sensor lamps are generally installed in the common entrance of corridors, corridors, emergency stairs, ceilings of entrances and exits in apartments, large-scale office buildings, etc., so users do not have to manually turn on / off the power switch. , Only when a person's movement is detected, it is automatically turned off after a certain period of time after lighting to prevent unnecessary waste of power.

일반적인 센서등은 상용 교류전원 220VAC의 입력에 의해 구동되도록 설계되어 있기 때문에, 정전시에는 건물 내부의 비상발전기에서 발전되는 비상전원 220VAC 를 비상전원회로에 인가하여 LED등을 점등한다.Since the general sensor lamp is designed to be driven by the input of commercial AC power 220VAC, in the event of a power failure, the emergency power 220VAC generated by the emergency generator inside the building is applied to the emergency power circuit to turn on the LED lamp.

본 발명의 목적은 배경이 되는 기술에 언급되었던 것처럼 다방면에 사용 되어지는 LED센서등이 센서의 동작 범위에서 만 조명이 동작되므로 거리가 멀리 떨어져 설치되어 있는 야간의 경우는 감지가 되어야만 점등이 되므로 불안감을 유발할 수 있다.특히 아파트의 계단식 비상계단의 센서등의 경우는 감지거리가 짧으면 더욱 불편함이 커진다.The object of the present invention is that the LED sensor light used in various fields, as mentioned in the background technology, operates only in the operating range of the sensor. In particular, in the case of a stepped emergency staircase sensor in an apartment, the shorter the sensing distance, the greater the inconvenience.

이러한 불편함을 해소하기 위하여 정전류 드라이버 IC 2개을 사용하여 위 문제를 해결하는 LED 디밍 센서등을 제공함에 있다.In order to solve this inconvenience, the present invention provides an LED dimming sensor that solves the above problem by using two constant current driver ICs.

상기 회로는 다음과 같이 동작한다.The circuit operates as follows.

a) 상시선에 전원이 공급되면 정류기(BD1)을 통하여 +전원이 공급이 되고,a) When power is supplied to the constant line, + power is supplied through the rectifier (BD1),

이 +전원은 A_module(90)과 B-module(30)에 전압이 인가되고,This + power supply is applied with voltage to A_module (90) and B-module (30),

상기 LED STRING(30)은 정전류 AC 구동 IC인 C_module(40)과 D_module(50)이 구동 되어도 이상 없도록 구성되었다. The LED STRING 30 is configured so that the C_module 40 and the D_module 50, which are constant current AC driving ICs, are driven.

상기 상시선에 전원이 공급되는 경우를 설명하였다.The case where power is supplied to the constant line has been described.

상기 상시선에 전원이 OFF 되고 비상선에 전원이 ON되면 정류기 BD1과 BD2의 +전원단자가 연결되어 있으므로 회로 구동은 동일하다.When the power is turned off to the constant line and the power is turned on to the emergency line, the circuit driving is the same because the + power terminals of the rectifiers BD1 and BD2 are connected.

특히 공동 복도나 지하 주차장 같은 곳에 상시로 등을 켜놓는 경우가 많은데 LED디밍 센서등을 설치하므로 전기료 절약과 기존 SMPS보다 부품이 적은 수량의 부품을 사용하므로 등의 수명에도 기여한다. In particular, in many cases, such as in common corridors or underground parking lots, lights are always turned on. Since LED dimming sensors are installed, it saves electricity bills and uses fewer components than existing SMPSs, contributing to the life of the lamps.

도면1과 도면2을 참조하면,Referring to Figures 1 and 2,

상시선 블록;상시선 L(180)과 상시선 N(190)이 있고 상시선 L과 퓨즈(160)가 연결되어 있고 퓨즈의 출력과 상시선 N사이에 바리스터(140)가 연결되어 있으며 바리스터 양단에 정류기인 브릿지 다이오드(10)가 연결되어 있다.A constant line block; there is a constant line L 180 and a constant line N 190, a constant line L and a fuse 160 are connected, a varistor 140 is connected between the output of the fuse and a constant line N, and both ends of the varistor.

상시선 정류기의 +단자에 다이오드(120)가 있어서 비상선의 전원에 영향을 받지 않으며,또한 비상선의 정류기의 +단자에 다이오드(130)이 연결되어 있어서 상시선의 전원에 영항을 미치지 못한다.Since the diode 120 is provided at the + terminal of the constant line rectifier, it is not affected by the power of the emergency line, and the diode 130 is connected to the + terminal of the rectifier of the emergency line, so that it does not affect the power of the constant line.

LED상시등을 유지하는 AC전용 정전류 LED드라이버(40)는 셋팅저항(100)값에 의해 LED스트링(30)를 점등한다.The AC-only constant current LED driver 40 that maintains the LED constant light turns on the LED string 30 according to the setting resistance 100 value.

LED센서등으로 동작하는 AC전용 정전류 LED드라이버(50)은 셋팅저항(110)값에 의해 추가적으로 LED스트링(30)을 점등하며,AC전용 정전류 LED드라이버(50)을 구동시키는 센서모듈(70)이 움직임이 감지되면 스위칭 모듈(60)을 구동하여 드라이버를 구동하게 된다.The AC-only constant current LED driver 50 operating as an LED sensor light additionally lights up the LED string 30 according to the setting resistance value 110, and the sensor module 70 driving the AC-only constant current LED driver 50 is operated. When motion is detected, the switching module 60 is driven to drive a driver.

또한 온도 보상회로가 들어있어서 110도 부근에서 동작하므로 회로가 안정적으로 동작한다.Also, since the temperature compensation circuit is included, it operates around 110 degrees, so the circuit operates stably.

상기 AC전용 정전류 LED드라이버를 사용하는 경우에 기존에 SMPS방식에 비해 비용이 저렴한 회로를 구성할수 있으며 회로 부품수가 적기 때문에 불량에 대한 부분도 경쟁력이 있다.In the case of using the AC-only constant current LED driver, it is possible to compose a circuit that is less expensive than the conventional SMPS method, and the number of circuit components is small, so the defect is competitive.

상기에 서술한 것처럼 상시로 구동되는 LED상시등과 센서로 구동하는 LED센서등이 일체로 구성되어 LED등의 수명과 생활의 편리성을 추구할 수 있다.As described above, the LED driving light driven by the constant light and the LED sensor light driven by the sensor are integrally formed, so that the life of the LED light and the convenience of life can be pursued.
