Description

형광등의 점등장치Lighting device of fluorescent lamp

제 1 도는 본 고안의 전체회로도.1 is an overall circuit diagram of the present invention.

* 도면의 주요부분에 대한 부호설명* Explanation of symbols on the main parts of the drawings

1 : 형광등 2,3 : 필라멘트1: fluorescent lamp 2,3: filament

일반 형광등은 글로우 스타터에 의하여 점등되므로 전원 투입과 동시에 수초동안 수회 깜박거림을 반복한 후 점등되며 이때 깜박 거릴때 마다 점등후의 소모전력에 비하여 3-7배의 첨두 전력을 발생시키는 결점이 있었다.Since ordinary fluorescent lamps are turned on by the glow starter, they turn on after repeated several times of blinking for several seconds at the same time as the power is turned on.In this case, each time of blinking, there is a drawback of generating peak power three to seven times higher than power consumption after lighting.

종래의 전자식 형광등 기구에서는 브리지 다이오드 및 캐퍼시터에 의하여 체배한 직류로서 형광등을 점등하거나 인터버에 의한 고주파 발생장치를 사용하여 형광등을 점등하는 방법을 사용하였다. 이러한 방법들은 일반 형광등기구에 비하여 순간 점등이 가능하거나 또는 절전등의 장점이 있지만 가장 치명적인 결점인 법광등의 흑화 현성을 초래하고 또한 고주파에 의한 전파가 발생하는 문제가 수반되었다. 이 결점중 형광등 흑화 현상을 줄이기 위하여 전용 형광램프를 사용하는 경우도 있었다.In the conventional electronic fluorescent lamp mechanism, a fluorescent lamp is used as a direct current multiplied by a bridge diode and a capacitor, or a fluorescent lamp is turned on by using a high frequency generator by an inverter. These methods have the advantage of instantaneous lighting or power saving lamps compared to general fluorescent lighting fixtures, but also cause blackening phenomena of forensic lamps, which is the most deadly defect, and also have a problem of radio wave generation by high frequency. Among these shortcomings, a special fluorescent lamp was used to reduce the blackening of the fluorescent lamp.

위에 지적한 일반 형광등에 대한 문제점인 순간점등. 종래의 전자식 형광등 기구에 있어서의 흑화 현상과 전과 방해에 대한 문제점 등을 개선하기 위하여 안출된 것으로 이를 첨부도면에 의하여 설명하면 다음과 같다.Momentary light, which is a problem with the ordinary fluorescent light pointed out above. The present invention has been devised to improve the blackening phenomenon and problems of electric shock and interference in the conventional electronic fluorescent light fixture, which will be described with reference to the accompanying drawings.

본 고안은 점등회로(가)와 공지의 게이트 구동회로(나) 및 검출회로(다)로서 구성된다.The present invention is composed of a lighting circuit (a), a known gate driving circuit (b) and a detection circuit (c).

본 고안의 점등회로(가)는 필라멘트(2)에 연결된 캐패시터(C3)에 사이닥(SD1), 캐패시터(C4)를 병렬로 연결하고 그 출측을 묶어 트라이악(TH2)을 연결하며, 그 출측을 다시 형광등(1)의 필라멘트(3)에 연결한다.The lighting circuit (a) of the present invention connects the sidak (SD 1 ) and the capacitor (C 4 ) in parallel to the capacitor (C 3 ) connected to the filament (2) and binds the exit side to connect the triac (TH 2 ). Then, the exit side is connected to the filament (3) of the fluorescent lamp (1) again.

이와같은 회로에 이와 병렬로 트라이악(TH2)의 게이트에 신호를 공급하는 구동회로(나)를 장치한다. 이 트라이악(TH2)의 구동회로(나)는 저항(R4)과 리드스위치(RS1) 캐퍼시터(C5)로 구성되고 리드스위치(RS1)와 캐퍼시터(C5)의 사이에 트라이악의 게이트를 연결한다. 그리고 위의 점등회로와 트라이악의 구동회로(나)병렬로 공지의 검출회로(다)를 장치한다.In such a circuit, a driving circuit (B) for supplying a signal to the gate of the triac TH 2 is provided in parallel thereto. The driving circuit ( b ) of the triac TH 2 is composed of a resistor R 4 and a reed switch RS 1 capacitor C 5 between the reed switch RS 1 and the capacitor C 5 . Connect evil gates. A well-known detection circuit (C) is provided in parallel with the above lighting circuit and the triac driving circuit (B).

입력에 전원이 투입되면 필라멘트(2)(3) 양단의 전압은 입력전압과 동일하다. 이 전압은 검출회로(다)에 의하여 리드스위치(RS1)작동하여 도통상태가 된다. 따라서 트라이악의 구동회로가 도통되며 트라이악의 게이트에 신호가 공급되어 트라이악(TH2)은 도통될 수 있는 여건을 갖게된다. 그러므로 캐퍼시터(C3)를 통한 전류는 사이닥(SD1)과 캐퍼시터(C4)를 통과하여 트라이악(TH2)을 거치면서 전압을 체배하여 순간점등을 가능하게 한다.When power is applied to the input, the voltage across the filament (2) (3) is equal to the input voltage. This voltage is brought into a conductive state by the operation of the reed switch RS 1 by the detecting circuit c. Therefore, the driving circuit of the triac conducts and a signal is supplied to the gate of the triac so that the triac TH 2 has a condition that can be conducted. Therefore, the current through the capacitor (C 3) is multiplied by the voltage goes through a triac (TH 2) to pass between the shut (SD 1) and a capacitor (C 4) to enable the instantaneous lighting.

이와같이 하여 형광등(1)이 점등되면 필라멘트(2)(3)의 양단전압은 입력전압에 비하여 현격히 저하되므로 (1/2-1/3) 검출회로(다)에 의하여 리드스위치(RS1)를 차단시킨다. 따라서 본 고안은 수회의 첨두전력을 발생하지 않으므로 절전효과를 가질 뿐 아니라 순간점등이 가능하게 되는 효과가 있다.In this way, when the fluorescent lamp 1 is turned on, the voltage at both ends of the filament 2 and 3 is significantly lower than the input voltage (1 / 2-1 / 3) so that the reed switch RS 1 is turned on by the detection circuit (C). Block it. Therefore, the present invention does not generate several peak powers, so it has the effect of saving power as well as instantaneous lighting.
