Description
제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.
본 고안은 많은 숫자의 형광등을 사용하는 공공건물에서 자연광의 밝기에 비례하여 자동적으로 조광이 되도록 한 자동제어 회로에 관한 것이다.The present invention relates to an automatic control circuit for automatically dimming in proportion to the brightness of natural light in a public building using a large number of fluorescent lamps.
주지된 바와 같이 현재 형광등에 대한 조광회로는 여러가지 방식이 개발되어 있고 또한 형광등 하나하나에 대하여는 수동으로서 조절하고 있다.As is well known, various types of dimming circuits for fluorescent lamps have been developed and manual control of fluorescent lamps is performed.
그러나 대형 공공건물의 경우는 많은 형광등을 동시에 켜고 있으며, 많은 사람들이 함께 사용하고 있으므로 이와 같은 형광등의 광도를 수동을 조절하기란 매우 어려운 것이다.However, in large public buildings, many fluorescent lights are turned on at the same time, and many people use them together, so it is very difficult to manually adjust the brightness of such fluorescent lights.
본 고안은 상기와 같은 점을 감안하여 안출한 것으로 자연광의 밝기에 따라 회로내부에 내장된 조광용 쎈서가 이를 감지하여 형광등에 흐르는 전류의 양을 적절히 증감시켜 형광등의 밝기를 자동으로 조절하여 주도록 된 것인데, 이하 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention was conceived in consideration of the above-mentioned point, and according to the brightness of natural light, the dimming sensor built in the circuit detects this, and appropriately increases or decreases the amount of current flowing through the fluorescent lamp to automatically adjust the brightness of the fluorescent lamp. When described in detail below with reference to the accompanying drawings.
제1도에서 A부분이 조광용 쎈서 및 비교기 회로이며, 나머지가 유도형 부하(트랜스나 쵸크를 말함) 전용인 L형(CONTOROL)제어회로이며, 쎈서에서 감지되는 자연광의 밝기에 따라 형광등의 밝기를 자동 또는 수동으로 제어하도록 되어 있다.In Figure 1, part A is a dimming sequencer and comparator circuit, and the rest is an L-type (CONTOROL) control circuit dedicated to inductive loads (refer to transformers or chokes), and the brightness of fluorescent lamps is adjusted according to the brightness of natural light detected by the sequencer. It is designed to control automatically or manually.
트라이액 1은 형광의 주전류 제어용 소자이며, 이것을 구동하는데 있어서 부하가 유도성이면 때에따라 제어가 불능상태에 이르는 경우가 흔히 있다.Triac 1 is a device for controlling the fluorescence main current, and when driving this, the control is often incapable when the load is inductive.
이것을 방지하려면 산에 트래이액과 그 주변회로를 유도성용으로 해주어야 되므로 트라이액은 L용과 R용이 있으므로 유동성용인 L을 쓰며 트라이액의 게이드 펄스도 충분한 전력과 폭이 넓은 파형을 주입해야 소기의 목적을 만족스럽게 행할 수 있다.To prevent this, the acid must be used for the induction of the tracer and its peripheral circuits. Since the triac has L and R, the liquid L is used. The triac's gate pulse must also be injected with sufficient power and a wide waveform. We can do it satisfactorily.
그리고 일반 조광기 회로의 R. C만 가지고 행하는 회로들은 간단해서 좋으나 결점이 여러가지 있어 만족할수가 없게 된다.In addition, circuits performed only with the R. C. of the general dimmer circuit may be simple but cannot be satisfied due to various defects.
소형트랜스(T1)에서는 입력전원을 48V로 낮추어서 전파 정류를 하고 직류화하여 저항(R1)을 거쳐 제너다이오드(ZD1)에서 맥류의 파두 우측을 잘라 준다.In the small transformer (T 1 ), the input power is reduced to 48V to rectify the wave, and the DC is cut to cut the right side of the pulse wave from the zener diode (ZD 1 ) through the resistor (R 1 ).
이것은 발진용 소자(U. J. T)에 가하여지고 가변저항(VR1)을 통해 콘덴서 (C1)에 충전되고 발진용 소자(U. J. T)의 오버점에 도달하며, 저항(R2)를 통한 맥류는 발진용 소자(U. J. T)의 B2에서 B1으로 순간적으로 흘러간다.It is applied to the oscillation element UJ T and charged to the capacitor C 1 through the variable resistor VR 1 and reaches the over point of the oscillation element UJ T, and the pulse flow through the resistor R 2 It flows momentarily from B 2 to B 1 of the oscillation element (UJ T).
콘덴서(C1)의 방전으로 B2와 B1간은 전류의 흐름이 정지하며 다시 콘덴서 (C1)이 충전 B2와 B1간에 전류가 흐르는 동작을 반복하여 발진이 계속되며, 발진용 소자(U. J. T)의 출력파형이 S. C. R1의 게이트를 흘러서 S. C. R1에는 전원 주기의 위상각을 제어하게 되어 충분한 전류와 전압치를 가진 제어 파형이 트라이액(TRAI C)의 게이트에 가해지므로 트라이액은 전원주기에 의한 위상각 제어에 추종하여 확실한 제어가 행하여진다.A capacitor (C 1) discharged by B between 2 and B 1 in by the flow of current stopped and re-condenser (C 1) repeats the operation in which a current flows between the charge B 2 and B 1 and the oscillation continues, the oscillating element the output waveform of (UJ T) is flowed to the gate of the SC R 1 SC R 1 and a control waveform with value sufficient current and voltage are controlled by the phase angle of the power cycle so applied to the gate of the triac (TRAI C) Triac Following the phase angle control by the power cycle, reliable control is performed.
광쎈서(SC)에서 검출된 신호는 가변저항(VR1)을 거쳐서 TR1의 베이스에 입력되는데 이때 발진용 소자(U. J. T)의 입력단에 TR1의 콜렉터가 접속되어 있어 TR1의 입력(광속량)이 많으면 발진용 소자(U. J. T)의 입력을 줄이는 쪽으로 작동되어서 발진용 소자(U. J. T)의 위상각 제어가 하강하여 형광등의 불빛이 어두운쪽으로 광쎈서(SD)의 검술광량에 반비례 되어 작동하여 밝으면 줄여주고 어두우면 밝게 자동 콘트롤 하는 작용을 가지고 있다.The signal detected by the optical ssenseo (SC) is it is variable via a resistor (VR 1) is input to the base of TR 1 wherein the collector of TR 1 connected to the input end of the oscillation element (UJ T) for the input of the TR 1 (light beam If the amount is large, it operates to reduce the input of the oscillation element (UJ T), so that the phase angle control of the oscillation element (UJ T) is lowered, and the light of the fluorescent lamp is inversely proportional to the amount of fencing light of the SD. If it is bright, it reduces. If it is dark, it automatically controls the brightness.
가변저항(VR1)은 설정용이며 TO1, TO2는 선도 스위치 자리를 말한다.The variable resistor (VR 1 ) is for setting and TO 1 , TO 2 are the leading switch seats.
