본 고안 AM/FM 수신기 또는 음향기기의 신호레벨 표시장치에 관한 것으로, 특히 램프를 이용하여 출력되는 신호의 크기를 세밀하게 표시하므로서 그 레벨정도를 정확히 알수 있도록한 램프구동식 신호레벨 표시장치에 관한 것이다.The present invention relates to a signal level display device of an AM / FM receiver or an acoustic device, and more particularly, to a lamp-driven signal level display device that accurately displays the magnitude of a signal output by using a lamp so as to accurately know the level. will be.

일반적으로 AM/FM 수신기 또는 음향기기에서는 그 음성출력정도는 기계적인 지침으로 상태를 판단하도록 하였으나 최근에는 거의 신호레벨 표시구동용 집적회로를 사용하여 발광디이오드를 다수개 설치하고 이를 출력 정도에 따라 켜도록 하므로서 그 정도를 확인 및 감지 하도록하여 왔다. 그러나 일반적으로 이용되는 신호레벨 표시구동용 집적회로가 발광다이오드를 구동시킬 수 있는 출력레벨이 극히 한정되어 있기 때문에 좀더 세밀한 신호레벨표시가 어려웠다.In general, the AM / FM receiver or sound equipment is used to determine the state of the sound output by mechanical guidance. However, recently, a large number of light emitting diodes are installed using an integrated circuit for signal level display driving. It has been turned on to check and detect the degree. However, the signal level display driving integrated circuit generally used has a very limited output level at which the light emitting diode can be driven.

또한 이러한 문제점을 개선시킨 종래의 장치에서는 부가적인 회로 구성과 발광다이오드의 추가가 필연적이었으며 최근의 고급하이파이 제품에 사용되는 액정표시 장치는 값이 매우 고가인 문제점이 있었다.In addition, in the conventional device that improves such a problem, additional circuit configuration and the addition of light emitting diodes are inevitable, and the liquid crystal display device used in recent high-end hi-fi products has a problem that the value is very expensive.

본 고안의 주 목적은 이와같은 문제점을 해결하여 고가의 액정에 비하여 효과는 동등 이상이고 값은 대단히 저렴한 램프구동식 신호레벨 표시장치를 제공하는데 있다.The main object of the present invention is to solve such a problem and provide a lamp driven signal level display device having an effect equal to or more than that of an expensive liquid crystal and having a very low cost.

다른 목적은 종래의 발광다이오드를 이용한 표시장치와 같은 획일적인 시각표시효과를 탈피하고 표시기의 다양한 구조에 따른 외적인 조형미와 램프의 다양한 빛깔로 시각적인 효과를 높이는 것이 가능하게 하는데 있다.Another object is to overcome the uniform visual display effects such as a display device using a conventional light emitting diode and to enhance the visual effect with external colors and various colors of the lamp according to various structures of the display.

이와같은 목적을 달설하기 위하여 본 고안에서는 입력신호의 약한 세력을 증폭회로에서 증폭시켜서 이 증폭된 신호를 램프 구동회로에 입력시키고 이 입력된 신호에 따라서 램프 구동회로에 접속된 램프가 구동되며 출력의 크기에 비례한 램프의 밝기가 표시기의 투광부를 통하여 출력되는 신호의 크기로 표시되도록 구성한다.In order to achieve this purpose, the present invention amplifies the weak force of the input signal in the amplifying circuit, inputs the amplified signal to the lamp driving circuit, and the lamp connected to the lamp driving circuit is driven according to the input signal. The brightness of the lamp in proportion to the size is configured to be displayed as the size of the signal output through the light emitting portion of the indicator.

제3도는 본 고안의 표시장치의 실시예시도이며 표시부(9)는 예를들면 투명아크릴 또는 베이클라이프판에 적층된 띠모양의 투광부(9b)가 있는 표시기(9a)를 배치하여 구성된다. 여기서 투광부(9b)의 모양이나 표시기(9a)와 램프(7)의 배치는 여러가지 방식으로 구성할 수 있다.3 is an exemplary view of an embodiment of the display device of the present invention, and the display portion 9 is configured by arranging, for example, a display 9a having a strip-shaped light transmitting portion 9b laminated on a transparent acrylic or bakelite plate. . Here, the shape of the light transmitting portion 9b and the arrangement of the indicator 9a and the lamp 7 can be configured in various ways.

이와같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

음성신호부(10)에서의 세력이 약한 음성입력신호를 비반전증폭회로(1)에서 배로 증폭시킨 다음다이오드(D1) (D2)에 의하여 반파배전압정류시켜서 에미터팔로우(4)인 트랜지스터(Q1)의 베이스로 입력되고 상기 트랜지스터(Q1)의 에미터 출력단에 나타난다.In the non-inverting amplifier circuit 1, the voice input signal having a weak force in the voice signal unit 10 is transferred. After amplification by a factor of two, half-wave voltage rectification is performed by the diodes D1 and D2 and input to the base of the transistor Q1, which is the emitter follower 4, and appears at the emitter output terminal of the transistor Q1.

이 에미터 출력신호는 저항(R8) (R10) (R12) (R14)에 의하여 분압되며 분압된 신호는 저항(R7) (R9) (R11) (R13)을 각각 거쳐서 다링통쌍(Q2) (Q3), (Q4) (Q5), (Q6) (Q7), (Q8) (Q9)의 각 베이스에미터 바이어스 조건을 이룬다. 상기 트랜지스터(Q1)의 에미터 출력에 비례하여 다링통쌍(Q2) (Q3), (Q4) (Q5), (Q6) (Q7), (Q8) (Q9)순으로 순차적으로 베이스에미터 바이어스조건을 만족시키게 되므로 램프(L1) (L2) (L3) (L4)순으로 점등되게 된다. 이때 다링통쌍(Q2) (Q3), (Q4) (Q5), (Q6) (Q7), (Q8) (Q9)이 동작될때 전류공급조건이 (Q2) (Q3)> (Q4) (Q5)> (Q6) (Q7)> (Q8) (Q9)순으로 되므로 램프의 점멸은 순차적으로 되나 램프의 밝기가 일정치 않게 되므로 R15>R16>R17>R18의 조건으로 이를 방지하게 된다. 이와같이 구동되는 램프(7)의 밝기가 표시기(9a)의 투광부(9b)를 통해서 출력레벨로 나타나게 된다.The emitter output signal is divided by resistors (R 8 ) (R 10 ) (R 12 ) (R 14 ) and the divided signals are divided into resistors (R 7 ) (R 9 ) (R 11 ) (R 13 ), respectively. Through this, each base emitter bias condition of the ring pair (Q 2 ) (Q 3 ), (Q 4 ) (Q 5 ), (Q6) (Q 7 ), and (Q 8 ) (Q 9 ) is achieved. Darring barrel pair (Q 2 ) (Q 3 ), (Q 4 ) (Q 5 ), (Q 6 ) (Q 7 ), (Q 8 ) (Q 9 ) in proportion to the emitter output of the transistor (Q 1 ) In order to satisfy the base emitter bias conditions sequentially, the lamps (L 1 ) (L 2 ) (L 3 ) (L 4 ) is turned on. At this time, the current supply condition is (Q 2 ) (Q 2 ) (Q 2 ) (Q 3 ), (Q 4 ) (Q 5 ), (Q6) (Q 7 ), (Q 8 ) (Q 9 ) 3)> since (Q 4) (Q 5) > (Q 6) (Q 7)> (Q 8) (Q 9) since the order off of the lamp is, but in order not the brightness of the lamp to a predetermined value R 15> This is prevented by the condition of R 16 > R 17 > R 18 . The brightness of the lamp 7 driven in this way is represented at the output level through the light projecting portion 9b of the indicator 9a.

상술한 바와같이 본 고안에서는 출력레벨이 램프의 밝기에 따라 투광부(9b)를 통해서 표시기(9a)상에 2차원 적으로 표시되므로 저렴한 가격으로 고가의 액정과 같은 세밀한 레벨표시에 대하여 동등이상의 효과를 낼수 있을뿐만 아니라 다수개의 발광다이오드를 하나의 램프로 대신할 수 있으므로 회로적으로 매우 간단해지며 본 고안과 같은 표시장치를 채용하므로 표시부의 다양한 램프광색의 취사선택과 투광부의 다양한 모양의 변화로 외적인 조형미와 시각적효과를 높일 수 있다.As described above, in the present invention, the output level is displayed two-dimensionally on the indicator 9a through the light-transmitting portion 9b according to the brightness of the lamp. Not only can it produce a large number of light-emitting diodes with a single lamp, but it is very simple in terms of circuits. By adopting a display device like the present invention, it is possible to select various lamp colors of the display part and change various shapes of the light emitting part. It can enhance external formative beauty and visual effects.
