Description

형광등용 조광기Fluorescent Dimmer

제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.

제2도는 종래의 제어회로.2 is a conventional control circuit.

제3도는 본 고안의 동작시 각부분의 파형도.3 is a waveform diagram of each part in the operation of the present invention.

본 고안은 형광등용 조광기에 관한 것이다.The present invention relates to a dimmer for fluorescent lamps.

현재 형광등의 조광장치는 여러나라에서 연구실험하고 있으나, 아직 실용화되어 있는 것이 없으며, 특히국내 실용신안등록 제26951호, 제26952호, 제28921호 등 본건 출원인의 선등록 고안들로 있으나 이것들도 수동조절에 의해서만 조광이 가능하도록 되어 있는 것이며 아니 널리 보급이 되지를 못하였다.Currently, dimming devices for fluorescent lamps have been researched and tested in various countries, but they have not been put to practical use. Especially, they are pre-registered by the applicants such as Korean Utility Model Registration Nos. 26951, 26952 and 28921, but these are also manual. Dimming is only possible by adjustment, and it is not widely available.

따라서 상기와 같은 종래 조광장치들을 연구 검토한 결과 다음과 같은 결점이 있었다.Therefore, as a result of studying and studying the conventional dimmers as described above, there were the following drawbacks.

첫째 : 종래의 제어장치(제2도)는 백열등용 조광기 그대로이며 목적이 저항제어용이기 때문에 불완전한 조광이 이루어진다.First: The conventional control device (Fig. 2) is an incandescent light dimmer and its purpose is resistance control, so incomplete dimming is achieved.

형광등용 조광회로는 어디까지나 유도성부하(트랜스)에 알맞은 "위상각보상회로"가 있는 것이어야 된다. 그 이유는 트랜스는 코일에 흐르는 주파수가 코일에 저항을 받아서 위상각이 60°∼90°도가 늦게 흘러 트라이액(TRIAC)의 게이트에 가해지는 펄스로 감당치 못해 트라이액의 유지전류를 완전히 확보치 못해서 불완전한 조광을 하고 있다.Fluorescent light dimming circuits should only have a "phase angle compensation circuit" suitable for inductive loads (trans). The reason for this is that the transformer is not able to cope with the pulse applied to the gate of TRIAC because the frequency flowing through the coil is resisted by the coil and the phase angle is 60 ° to 90 °. Incomplete dimming.

둘째 : 제어용 볼륨의 조정눈금이 올림시와 내림시 모두 틀려서 매우 불확실한 조광위치을 나타내어서 사용상 매우 불편하다.Second: It is very inconvenient to use because it shows very uncertain dimming position because the adjustment scale of control volume is wrong at both raising and lowering.

본 고안은 상기와 같은 점을 보완하여 보다 정확하고 안전하게 조광을 할 수 있도록 하였으며, 특히 실내의 밝고 어두움에 따라 자동으로 조광이 이루어지도록 하기 위하여 자동조광장치 회로까지 포함시킨 것으로 이하 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made to compensate for the above points to more accurately and safely dimming, in particular to include the automatic dimmer circuit in order to automatically adjust the dimming according to the light and dark of the room in detail by the accompanying drawings The explanation is as follows.

제1도에는(LAMP)는 20W40W용 형광구이며(PT1)은 유도성인 트랜스이다.Figure 1 (LAMP) is 20W Fluorescent bulb for 40 W (PT 1 ) is an inducible trans.

(L)은 소형쵸크 코일이며(T1) (T2) (T3) (T4)는 트랜스의 1차권선 및 2차권선 겸용 코일의 소자이다.(L) is a small choke coil (T 1 ) (T 2 ) (T 3 ) (T 4 ) is a device of the primary winding and secondary winding coil of the transformer.

(SW1)은 100V200V를 절환하는 스위치이며 1번은 220V,2번은 100V이다.(SW 1 ) is 100V It is a switch to switch 200V, No. 1 is 220V, No. 2 is 100V.

(T2)에서 (T4)간이 2차권선이며(누설전류권선) (T1)에서 (T2)간이 110V권선, (T2)에서 (T3)간이 110V권선 (T2)에서 (T1)간이 110V이다.(T 2 ) to (T 4 ) is a secondary winding (leakage current winding) and (T 1 ) to (T 2 ) is 110V winding, (T 2 ) to (T 3 ) is 110V winding (T 2 ) to ( T 1 ) is 110V.

(F1) (F2)는 필라멘트 가열용 권선이며 쵸크(L)는 안정화용으로 사용한다.(F 1 ) (F 2 ) is filament heating winding and choke (L) is used for stabilization.

(Vo) (Vo)간이 벽면스위치나 배전판 스윗치에 해당하며 여기에 조광제어기를 부착하여 VR로 된 볼륨을 손으로 돌려 광도를 설정하고 광도의 자동조절은 (TR)의 베어스에(S) (S) 광센서를 부착하여 트랜지스터(TR)로 증폭 및 수동조정과 비교하여 실내의 광도를 자동조정한다.(Vo) (Vo) This corresponds to a simple wall switch or switchboard switch, and a dimming controller is attached to it to turn the VR volume by hand to set the brightness. ) Light sensor in the room is automatically adjusted in comparison with amplification and manual adjustment by transistor (TR).

저항(R5)와 가변저항(VR)으로 콘덴서(C1)에 충전하여 다이액(DA)을 통해 트라이액(TRIAC1)의 게이트에 좁은 폭의 펄스를 가하면 트라이액(TRIAC1)이 도통되면서 저항(R5)을 통한 주전류가 트라이액(TRIAC1)의 애노드와 캐소드간을 흘러서 제3도의 (C)와 같은 폭이 넓은 게이트 전류가 트라이액(TRIAC2)의 게이트에 흘러서 완전하게 트라이액(TRIAC2)을 구동하므로 위상이 늦고 빠름에 관계없이 트라이액(TRIAC2)의 게이트에 흘러서 완전하게 트라이액(TRIAC2)을 구동하므로 위상이 늦고 빠름에 관게없이 트라이액(TRIAC2)은 완전한 제어각에 따라서 PT1에 전력을 충분히 안정되게 공급하게 된다.When the capacitor (C 1 ) is charged with the resistor (R 5 ) and the variable resistor (VR) and a narrow pulse is applied to the gate of the triac (TRIAC 1 ) through the die liquid (DA), the triac (TRIAC 1 ) becomes conductive. The main current through the resistor (R 5 ) flows between the anode and the cathode of the triac (TRIAC 1 ) so that a wide gate current such as (C) in FIG. 3 flows to the gate of the triac (TRIAC 2 ) to complete triac (TRIAC 2) for driving so that the phase late, so late phase drives the triac (TRIAC 2) the triac (TRIAC 2) as to flow completely to the gate regardless of the fast without gwange the fast triac (TRIAC 2) The power supply to PT 1 is sufficiently stable according to the complete control angle.

만약 트라이액(TRIAC2)이 없으면 제3(b)도와 같은 게이트 펄스가 가해지나 위상이 늦어져서 전류가 흐르지 못하고 시간이 지연되면 가늘과 날카로운 게이트 펄스가 거의 사라져 가는 때 전류가 늦게 흐르려고 해도 게이트 신호가 사라진 뒤에는 흐를수가 없게되어 아주 불안정한 상태가 되어 버린다.If there is no TRIAC 2 , a gate pulse is applied as shown in FIG. After the signal disappears, it cannot flow and becomes very unstable.

트라이액(TRIAC1)은 애노드에 연결된 저항(R5)을 통해서 주전류 +가와 있다.Triac 1 has a main current + through a resistor R 5 connected to the anode.

이와 같은 것은 저항부하가 +전극에 접속되어 있는 결과나 마찬가지므로 위상이 늦음이 없이 펄스의 날카로운 게이드 신호에도 작동하면 +파형의 전류가 끝날때까지 트라이액(TRIAC1)의 애노드와 캐소드간의 전류는 계속 흘러 트라이액(TRIAC2)의 늦은 유도성부하 위상각 60°∼90°정도는 아무런 영향없이 전류를 흘러주게 된다.This is similar to the result of the resistive load being connected to the + electrode, so if it operates on the sharp signal of the pulse without delaying the phase, the current between the anode and the cathode of the triac (TRIAC 1 ) until the current of the + waveform ends. The continuous inductive load phase angle of 60 ° to 90 ° of the triac (TRIAC 2 ) flows without any influence.

저항(R1) 다이오드(D1) (D2) (D3) 저항(R3) 다이오드(D4)는 가변저항의 올림 내림시 차이를 없애주는 시정수로서 콘덴서(C1)의 충전전류를 보충해주는 역할을 하므로 콘덴서(C1)의 방전이 다소 길어져서 (DA)의 순간방전이 약간 길어지게 작용하는 소자들이다.Resistance (R 1) a diode (D 1) (D 2) (D 3) resistance (R 3) a diode (D 4) is the charging current of the capacitor (C 1) as a time constant, which eliminates the difference when rounding down of the variable resistor Since the discharge of the capacitor (C 1 ) is somewhat longer, the momentary discharge of (DA) is slightly longer.

트랜지스터(TR)는 광쎈서의 광속에 비례해서 콘덴서(C1)의 방전시간을 단축하게 작용한다.The transistor TR acts to shorten the discharge time of the capacitor C 1 in proportion to the luminous flux of the optical beam.

광이 밝으면 트라이액(TRIAC)의 주전류가 작아지며 광이 어두어지게 한다.The brighter the light, the smaller the main current of the TRIAC and the darker the light.

반대로 광이 어두우면 트라이액의 주전류가 많아지며 광이 밝아진다.On the contrary, when the light is dark, the triac main current increases and the light becomes bright.

저강(R6)과 콘덴서(C2)는 트라이액(TRIAC2) 보호용 시정수이며, SW2는ON하면 즉시 점등이 되며 조광은 최고로 되고 off로 하면 종래의 설정 광도로 되돌아 간다.Low-strength (R 6 ) and condenser (C 2 ) is a time constant for the protection of triac (TRIAC 2 ), SW 2 is turned on immediately when turned ON, dimming is the highest, and when off, it returns to the conventional set brightness.

제3도에서 (A)는 기본 파형이고 (B)는 트라이액(TRIAC1) 게이트 전류 파형이며 (C)는 (TRIAC2)의 게이트전류 파형(D)는 트라이액(TRIAC2)의 주전극에 흐르는 파형이다.In the third degree (A) is a basic waveform (B) is a main electrode of the triac (TRIAC 1) gate current waveform and (C) is (TRIAC 2) gate current waveform (D) of the triac (TRIAC 2) The waveform flowing in.
