본 고안은 형광등용 디밍(조광)전자식안정기를 백열등조광기와 같이 볼륨으로 형광등 밝기를 조절할 수 있도록 디밍신호전압을 1~10V로 제어하는 유닛 형광등 조광제어기에 관한 것이다.The present invention relates to a unit fluorescent light dimming controller for controlling the dimming signal voltage to 1 ~ 10V so that the fluorescent dimming electronic ballast can adjust the brightness of the fluorescent lamp in volume, such as incandescent light dimmer.

종래의 형광등용 조광제어기는, 220V 상용전원에서 형광등 조광제어기 동작전원을 공급하기 위한 회로가 별도로 설치되어 있어서 회로가 복잡하고 입출력선도 많아 시공의 어려움이 있었다. Conventional fluorescent light control controller has a separate circuit for supplying the operating power of the fluorescent light control controller from the 220V commercial power source has a complicated circuit and a lot of input and output lines, there was a difficulty in construction.

또한, 종래에는 별도의 전류보정부가 구비되어 있지 않아 형광등용 디밍전자식안정 기가 여러개 병렬로 연결 때마다 볼륨조정 위치가 달라지게 되는 문제가 있었다.In addition, conventionally, since a separate current compensator is not provided, there is a problem in that the volume adjusting position is changed every time the dimming electronic ballasts for fluorescent lamps are connected in parallel.

본 고안은 이와 같은 종래의 결점을 해결하기 위한 것으로, 본 고안의 목적은, 형광등용 디밍전자식안정기를 백열등이나 자기식 할로겐 안정기처럼 볼륨(가변저항)을 돌려서 디밍을 하도록 디밍신호전압을 1 ~ 10V로 제어하는 유닛 형광등 조광제어기를 제공하는데 있다.The present invention is to solve such a conventional drawback, the object of the present invention, the dimming signal voltage is 1 ~ 10V so that the dimming electronic ballast for fluorescent lamp dimming by turning the volume (variable resistor) like incandescent lamp or magnetic halogen ballast It is to provide a unit fluorescent light control controller.

이와 같은 목적을 달성하기 위한 본 고안은 저항값을 가변시켜 저항값 최소시 디밍(+)의 전압을 증가시키고 저항값 최대시 디밍(+)의 전압을 감소시키는 볼륨부와, 상기 볼륨부의 저항값변화에 따라 전류를 제어하여 안정기의 조광제어단자에 10 ~ 15V/1㎃의 전압/전류가 흐르는 것을 이용하여 조광제어단자전압이 1 ~ 10V가 되도록 하는 전류제어부와, 상기 조광제어단자에 접속되어 상기 전류제어부의 전류를 보정하는 전류보정부를 포함하여 구성함을 특징으로 한다.The present invention for achieving the above object is a volume portion for varying the resistance value to increase the voltage of the dimming (+) when the resistance value minimum and dimming (+) at the maximum resistance value, and the resistance value of the volume portion A current control unit which controls the current according to the change so that the dimming control terminal voltage is 1 to 10V by using a voltage / current of 10 to 15V / 1 에 flowing to the dimming control terminal of the ballast, and is connected to the dimming control terminal Characterized in that it comprises a current correction unit for correcting the current of the current control unit.

이하, 본 고안의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, the embodiment of the present invention in detail.

도 1은 본 고안의 블럭도로, 볼륨부(10)와 전류제어부(20) 및 전류보정부(30)로 구성된다.1 is a block diagram of the present invention, the volume unit 10 and the current control unit 20 and the current correction unit 30.

도 2는 본 고안의 회로도로, 저항(R1)(R2), 가변저항(VR1), 콘덴서(C1)로 구성되는 볼륨부(10)와, 트랜지스터(Q1-Q3), 저항(R3-R5)으로 구성되는 전류제어부(20)와, 트랜지스터(Q4), 저항(R6), 제너다이오드(ZD1), 다이오드(D1), 콘덴서(C2)로 구성된 전류보정부(30)로 구성된다.FIG. 2 is a circuit diagram of the present invention, which includes a volume section 10 composed of resistors R1, R2, variable resistor VR1, and capacitor C1, transistors Q1-Q3, and resistors R3-R5. And a current compensator 30 composed of a transistor Q4, a resistor R6, a zener diode ZD1, a diode D1, and a capacitor C2.

이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

통상, 형광등용 디밍전자식안정기는 DC전압에 의한 제어방식인 경우 디밍신호단자의 전압이 0 ~ 1V 일 때 최소밝기로 되고 1 ~ 10V 사이에서는 서서히 밝아져야 한다.In general, the dimming electronic ballast for fluorescent lamps is the minimum brightness when the voltage of the dimming signal terminal is 0 ~ 1V in the case of the control method by DC voltage, and should be gradually brightened between 1 ~ 10V.

그리고 10 ~ 11V 일 때는 최대밝기로 되고 조광제어기가 연결되지 않을 경우에는 최대밝기를 유지해야 한다.The maximum brightness is between 10 and 11V, and the maximum brightness should be maintained when no dimmer controller is connected.

또한, 조광제어기 제어단자의 극성을 역방향으로 연결하는 경우에는 형광등용 디밍전자식안정기가 최소밝기를 유지하게 된다.In addition, when the polarity of the dimming controller control terminal is connected in the reverse direction, the dimming electronic ballast for the fluorescent lamp maintains the minimum brightness.

형광등용 디밍전자식안정기는 조광제어단자에 10 ~ 15V/1㎃정도의 전압/전류가 흐르는데, 본 고안의 유닛 형광등 조광제어기는 이러한 전압/전류를 이용하여 형광등의 밝기를 제어하게 된다.The dimming electronic ballast for fluorescent lamps has a voltage / current of about 10 to 15V / 1 mA flowing through the dimming control terminal. The unit fluorescent lamp dimming controller of the present invention controls the brightness of fluorescent lamps using such voltage / current.

즉, 볼륨부(10)의 저항값에 따라 유닛 형광등 조광제어기에 흐르는 전류를 제어하여 형광등용 디밍전자식안정기의 조광제어단자전압이 1 ~ 10V가 되도록 한다.That is, the dimming control terminal voltage of the dimming electronic ballast for fluorescent lamps is controlled to be 1 to 10V by controlling the current flowing through the unit fluorescent lamp dimming controller according to the resistance value of the volume unit 10.

만일, 볼륨부(10)를 이루는 가변저항(VR1)의 저항값이 최소가 되면 트랜지스터(Q1)의 베이스전류가 감소하므로 컬렉터전류도 감소하게 된다. If the resistance value of the variable resistor VR1 constituting the volume unit 10 becomes minimum, the base current of the transistor Q1 decreases, so that the collector current also decreases.

따라서, 트랜지스터(Q1)의 컬렉터전류가 감소하면, 트랜지스터(Q2)의 베이스전압은 증가하여 베이스전류가 감소하고 컬렉터전류도 감소한다. Therefore, when the collector current of transistor Q1 decreases, the base voltage of transistor Q2 increases, so that the base current decreases and the collector current also decreases.

이와 같이 트랜지스터(Q2)의 컬렉터전류가 감소하면, 결과적으로 트랜지스터(Q3)의 베이스전류가 감소하면서 트랜지스터(Q3)의 컬렉터전류도 감소하여 디밍(+)의 전압이 증가한다.As such, when the collector current of transistor Q2 decreases, as a result, the base current of transistor Q3 decreases while the collector current of transistor Q3 also decreases, so that the voltage of dimming (+) increases.

저항(R2)의 저항값을 조정하여 디밍(+)의 전압이 10V가 되도록 한다.Adjust the resistance value of the resistor R2 so that the voltage of the dimming (+) is 10V.

상기와 반대로, 가변저항(VR1)의 저항값이 최대가 되면 트랜지스터(Q1)의 베이스전류가 증가하고 컬렉터전류도 증가하게 된다. On the contrary, when the resistance value of the variable resistor VR1 becomes maximum, the base current of the transistor Q1 increases and the collector current also increases.

따라서, 트랜지스터(Q1)의 컬렉터전류가 증가하면, 트랜지스터(Q2)의 베이스전압은 감소하여 베이스전류가 증가하고 컬렉터전류를 증가하게 한다. Therefore, when the collector current of transistor Q1 increases, the base voltage of transistor Q2 decreases, causing the base current to increase and the collector current to increase.

트랜지스터(Q2)의 컬렉터전류가 증가하게 되면 결과적으로 트랜지스터(Q3)의 베이스 전류가 증가하고 트랜지스터(Q3)의 컬렉터전류가 증가하여 디밍(+)의 전압이 감소한다. As the collector current of transistor Q2 increases, the base current of transistor Q3 increases and the collector current of transistor Q3 increases, thereby decreasing the voltage of dimming (+).

저항(R1)의 저항값을 조정하여 디밍(+)의 전압이 1V가 되도록 한다.Adjust the resistance value of the resistor R1 so that the voltage of the dimming (+) is 1V.

전류보정부(30)의 트랜지스터(Q4)는 디밍(+)의 전압이 0 ~ 1.2V까지는 디밍(+)의 전압이 증가함에 따라 트랜지스터(Q1)의 에미터에 연결된 저항(R4)에 전류를 보정(바이패스)하여 디밍(+)의 전압이 빨리 증가하는 것을 제한한다. The transistor Q4 of the current compensator 30 supplies current to the resistor R4 connected to the emitter of the transistor Q1 as the voltage of the dimming (+) increases from 0 to 1.2V. Correction (bypass) limits the rapid increase in the voltage of the dimming (+).

따라서, 형광등용 디밍전자식안정기를 낮은 밝기에서 미세하게 조절할 수 있는 것이다.Therefore, the dimming electronic ballast for fluorescent lamps can be finely adjusted at low brightness.

디밍(+)의 전압이 1.3 ~ 10V구간에서는 디밍(+)의 전류가 증가(형광등용 디밍전자식안정기가 여러개 병렬로 연결 되는 경우)하더라도 정전압회로로 동작하여 볼륨에 의해 조정된 디밍(+)의 전압을 유지하도록 한다.In the dimming voltage range of 1.3 to 10V, even if the dimming current increases (when several dimming electronic ballasts for fluorescent lamps are connected in parallel), the dimming (+) Keep the voltage.

다이오드(D1)는 유닛 형광등 조광제어기의 단자가 역방향으로 연결될 때 형광등용 디밍전자식안정기의 밝기를 최소밝기로 되게하고, 유닛 형광등 조광제어기의 부품을 보호해 준다.The diode D1 makes the brightness of the dimming electronic ballast for fluorescent lamps minimum brightness when the terminals of the unit fluorescent lamp dimming controller are connected in the reverse direction, and protects the components of the unit fluorescent lamp dimming controller.

콘덴서(C2)는 디밍(+)의 전압이 낮을 때 안정적으로 동작하도록 함과 함께 노이즈필터기능을 한다.Capacitor C2 operates stably when the dimming voltage is low and functions as a noise filter.

이상에서 상세히 설명한 바와 같은 본 고안은 간단히 볼륨부(10)를 조절하여 디밍(+)의 전압을 1 ~ 10V가 되도록 제어할 수 있는 효과가 있다.The present invention as described in detail above has the effect of controlling the voltage of the dimming (+) to 1 ~ 10V by simply adjusting the volume unit 10.

또한, 본 고안은 입출력선이 2개이므로 시공이 간편하고 별도의 전류보정부(30)가 구비되어 있어 형광등용 디밍전자식안정기를 여러개 병렬로 연결해도 볼륨조정 위치가 변하지 않는 효과가 있다.In addition, since the present invention has two input and output wires, the construction is simple, and a separate current correction unit 30 is provided, so that even if the dimming electronic ballasts for fluorescent lamps are connected in parallel, the volume adjustment position does not change.

또한, 본 고안의 유닛 형광등 조광제어기는 여러개의 형광등용 디밍전자식안정기가 연결되어 사용중에 형광등의 수명이 다되어 한 두개의 안정기가 동작을 하지 않더라도 볼륨으로 조정된 밝기를 그대로 유지할 수 있는 효과가 있다.In addition, the unit fluorescent lamp dimming controller of the present invention is connected to the dimming electronic ballast for several fluorescent lamps, the end of the life of the fluorescent lamp during use, there is an effect that can maintain the brightness adjusted by the volume even if one or two ballasts do not operate .
