본 고안은 자동판매기의 광고판넬 내부에 마련된 형광등의 제어회로에 관한 것으로, 특히 자동판매기가 설치된 주위의 환경에 따라 여러가지 방법으로 점소등 제어할 수 있도록 한 자동판매기의 형광등 제어회로에 관한 것이다. 종래, 자동판매기(이하 자판기라 한다)에 설치되어 광고면을 밝혀주는 형광등은 스위치를 조작하여 점등시켜주거나 소등시켜준다. 또한, 주위의 밝기에 따라 주위가 어두워지면 점등시키고, 주위가 밝으면 자동으로 소등시켜주는 것도 있었다. 그러나, 실내에 설치되는 자판기의 경우에는 판매행위가 종료되고 자판기 관리자가 자판기가 설설된 장소(실내)를 벗어날때 항시 수동조작으로 상기 형광등을 소등해야 되는 번거로움이 있었다.The present invention relates to a control circuit of a fluorescent lamp provided in the advertising panel of the vending machine, and more particularly, to a fluorescent lamp control circuit of the vending machine that can be controlled by turning on and off in various ways according to the surrounding environment in which the vending machine is installed. Conventionally, a fluorescent lamp installed in a vending machine (hereinafter referred to as a vending machine) to illuminate an advertisement surface turns on or off by operating a switch. In addition, depending on the brightness of the surroundings, the lights were turned on when the surroundings became dark, and turned off automatically when the surroundings were bright. However, in the case of a vending machine installed indoors, when the sales activity is ended and the vending machine manager leaves the place where the vending machine is installed (indoor), there is a hassle to turn off the fluorescent lamp by manual operation at all times.

본 고안은 상기 문제점을 해결하기 위하여 안출된 것으로, 실내에 설치되는 자판기 형광등의 점소등을 자동으로 제어할 뿐 아니라, 실외에 설치되는 자판기 형광등도 자동으로 점소등 될 수 있도록 한 자판기의 형광등 제어회로를 제공함에 본 고안의 목적이 있다. 이하 첨부된 도면에 의거하여 본 고안을 설명한다.The present invention was devised to solve the above problems, and the fluorescent lamp control circuit of the vending machine not only automatically controls the flashing lights of the vending machine fluorescent lamps installed in the room, but also automatically lights the vending machine fluorescent lamps installed in the outdoors. To provide a purpose of the present invention. Hereinafter, the present invention will be described based on the accompanying drawings.

비교기(COM)의 반전단자(-)에는 광감지소자(cds)와 저항(R1)의 분압전압이 인가되도록 접속되고, 비교기(COM)의 비반전단자(+)에는 가변저항(VR)과 저항(R2)의 분압전압이 인가되도록 접속되고, 상기 비교기(COM)의 출력이 저항(R3), 콘덴서(C1) 및 저항(R4)를 통해 인버터(I1)의 입력에 접속되고, 이 인버터(I1)의 출력이 4단 스위치(SW)의 고정단자(P2)에 접속됨과 동시에 인버터(I2)를 통해 상기 4단 스위치(SW)의 고정단자(P3)에 접속된다. 또한, 4단 스위치(SW)의 고정단자(P1)에는 소정직류전압(V2:12V)이 인가되고, 4단 스위치(SW)의 고정단자(P4)는 접지된다.The photosensitive element cds and the divided voltage of the resistor R 1 are applied to the inverting terminal (-) of the comparator COM, and the variable resistor VR is connected to the non-inverting terminal (+) of the comparator COM. The voltage divider voltage of the resistor R 2 is connected, and the output of the comparator COM is connected to the input of the inverter I1 through the resistor R 3 , the capacitor C 1 , and the resistor R 4 . The output of the inverter I1 is connected to the fixed terminal P 2 of the four-stage switch SW and is connected to the fixed terminal P 3 of the four-stage switch SW via the inverter I2. In addition, a predetermined direct current voltage V 2 : 12V is applied to the fixed terminal P 1 of the four-stage switch SW, and the fixed terminal P 4 of the four-stage switch SW is grounded.

한편, 상기 4단 스위치(SW)의 가동단자(P5)는 릴레이(RY)의 코일단에 연결되고, 상기 릴레이(RY)의 스위치단에 형광등(L1)과 전원(AC)이 연결된다.Meanwhile, the movable terminal P 5 of the four-stage switch SW is connected to the coil terminal of the relay RY, and the fluorescent lamp L 1 and the power supply AC are connected to the switch terminal of the relay RY. .

미설명부호 V1은 직류전원(5V), D1은 다이오드다. 상기와 같이 구성시켜서된 본 고안의 작용효과를 설명한다. 첫째, 4단스위치(SW)의 가동단자(P5)를 고정단자(P1)에 접속한 경우, 릴레이(RY)는 차단되어 주위의 밝기에 상관없이 형광등(L1)은 소등상태를 유지한다.Reference numeral V 1 is a DC power supply (5V), D 1 is a diode. It describes the operation and effect of the subject innovation configured as described above. First, when the movable terminal P 5 of the four-stage switch SW is connected to the fixed terminal P 1 , the relay RY is blocked so that the fluorescent lamp L 1 remains off regardless of the surrounding brightness. do.

둘째, 자판기가 실외에 설치되어, 4단스위치(SW)의 가동단자(P5)를 고정단자(P2)에 접속한 경우, 먼저 주위가 어두우면 광감지소자(cds)의 저항이 증대하여 비교기(COM)의 반전단자에 걸리는 전압이 비반전단자에 걸리는 전압보다 작게되어 비교기(COM)는 하이신호를 출력한다. 따라서 이때 출력되는 하이신호는 인버터(I1)를 통해 반전되고 4단스위치(SW)를 통해 릴레이(RY)를 통전시켜 형광등(L1)을 점등시킨다. 그러나, 주위가 밝아지면 광감지소자(cds)의 저항이 감소하여 비교기(COM)의 반전단자에 걸리는 전압이 비반전단자에 걸리는 전압보다 크게되어 비교기(COM)는 로우신호를 출력한다. 따라서 이때 출력되는 로우신호는 인버터(I1)를 통해 반전되고 4단스위치(SW)를 통해 릴레이(RY)를 차단시켜 형광등(L1)을 소등시킨다. 셋째, 자판기가 실내에 설치되어, 4단스위치(SW)의 가동단자(P5)를 고정단자(P3)에 접속한 경우, 먼저 상기 자판기가 설치된 실내의 문을 잠그고 관리자가 나갈때, 곧 실내등을 소등(이후 판매행위가 없다고 봄)하여 주위가 어두우면 광감지소자(cds)의 저항이 증대하여 비교기(COM)의 반전단자에 걸리는 전압이 비반전단자에 걸리는 전압보다 작게되어 비교기(COM)는 하이신호를 출력한다. 따라서 이때 출력되는 하이신호는 인버터(I1)를 통해 반전되고, 인버터(I2)를 통해 또 반전되어 4단스위치(SW)를 통해 릴레이(RY)를 차단시켜 형광등(L1)을 소등시킨다. 그러나, 실내에 관리자(또는 사용자)가 들어와서 실내등을 켜서 주위가 밝으면 광감지소자(cds)의 저항이 감소하여 비교기(COM)의 반전단자에 걸리는 전압이 비반전단자에 걸리는 전압보다 크게되어 비교기(COM)는 로우신호를 출력한다. 따라서 이때 출력되는 로우신호는 인버터(I1)를 통해 반전되고 인버터(I2)를 통해 또 반전되어 4단스위치(SW)를 통해 릴레이(RY)를 통전시켜 형광등(L1)을 점등시킨다. 넷째, 4단스위치(SW)의 가동단자(P5)를 고정단자(P4)에 접속한 경우, 릴레이(RY)는 통전되어 형광등(L1)의 주위의 밝기에 상관없이 점등상태를 유지한다. 이상에서와 같이 본 고안은 자판기가 설치되는 장소에 따라 형광등의 점소등을 적절히 선택하여 사용함으로써, 절전의 효과가 있다.Second, when the vending machine is installed outdoors and the movable terminal P 5 of the 4-stage switch SW is connected to the fixed terminal P 2 , first, when the surroundings are dark, the resistance of the photosensitive elements cds increases. Since the voltage applied to the inverting terminal of the comparator COM is smaller than the voltage applied to the non-inverting terminal, the comparator COM outputs a high signal. Therefore, the high signal output at this time is inverted through the inverter I1 and energizes the relay RY through the four-stage switch SW to turn on the fluorescent lamp L 1 . However, when the ambient light becomes brighter, the resistance of the photosensitive device cds decreases, so that the voltage applied to the inverting terminal of the comparator COM is greater than the voltage applied to the non-inverting terminal, and the comparator COM outputs a low signal. Therefore, the output low signal is inverted through the inverter I1 and the relay RY is turned off through the four-stage switch SW to turn off the fluorescent lamp L 1 . Third, when the vending machine is installed indoors and the movable terminal P 5 of the four-stage switch SW is connected to the fixed terminal P 3 , first lock the door of the room where the vending machine is installed and the manager exits the room light. When the light is dark (after no sales), the resistance of the photosensitive device cds increases, so the voltage applied to the inverting terminal of the comparator COM is smaller than the voltage applied to the non-inverting terminal. Outputs a high signal. Therefore, the high signal output at this time is inverted through the inverter I1 and inverted again through the inverter I2 to cut off the relay RY through the four-stage switch SW to turn off the fluorescent lamp L 1 . However, when the manager (or user) enters the room and the room is lit and the surroundings are bright, the resistance of the photosensitive elements cds decreases, so that the voltage applied to the inverting terminal of the comparator COM is greater than the voltage applied to the non-inverting terminal. The comparator COM outputs a low signal. Therefore, the output low signal is inverted through the inverter I1 and inverted through the inverter I2 to energize the relay RY through the four-stage switch SW to turn on the fluorescent lamp L 1 . Fourth, when the movable terminal P 5 of the four-stage switch SW is connected to the fixed terminal P 4 , the relay RY is energized to maintain the lighting state regardless of the brightness around the fluorescent lamp L 1 . do. As described above, the present invention has an effect of saving power by appropriately selecting and using a flashing light such as a fluorescent lamp according to a place where a vending machine is installed.
