본 고안은 발광소자(LED) 표시기에 관한 것으로서, 더욱 상세하게는 중앙집중열차제어(CTC)용 표시 및 제어장치인 LDP(Line Dispacher Panel)의 신호용 소형 모자이크 판넬에 설치되는 발광소자 표시기로서 다양한 색상을 나타낼 수 있으며, 사용수명을 증대시킬 수 있도록 한 것이다.The present invention relates to a light emitting device (LED) display, and more particularly, a light emitting device display installed in a small mosaic panel for signal of a LDP (Line Dispacher Panel) which is a display and control device for a centralized train control (CTC). It can be used to increase the service life.

종래의 중앙집중열차 제어용표시 및 제어장치인 LDP와 감시자의 제어반에 있는 콘트롤판넬은 제1도 및 제2도에 나타낸 바와 같이, 유리구의 중앙에 필라멘트를 부착하여 도입선에 전원을 인가시켜 단색의 빛을 발산하는 소형백열전구 형태의 램프(8)를 사용하여 그 불빛에 의해 표시역할을 하게되고, 상기 판넬을 구성하는 모자이크 판넬은 램프(8)가 삽입되도록 내부가 벌집형으로 되어 삽입시에 램프(8)의 몸통단자에 해당되는 A부분이 모자이크 판넬의 공통단자(7)에 고정되도록 접속되며, B단자로 외부입력단자로 연결된다.As shown in FIGS. 1 and 2, the control panel in the control panel of the LDP and the monitor for the conventional centralized train control and the control unit are attached with a filament in the center of the glass sphere to supply power to the lead line to provide a monochromatic light. The lamp (8) in the form of a small incandescent lamp that emits the light serves as a display by the light, and the mosaic panel constituting the panel has a honeycomb inside so that the lamp (8) is inserted into the lamp at the time of insertion Part A corresponding to the trunk terminal of (8) is connected to be fixed to the common terminal 7 of the mosaic panel, and is connected to the external input terminal to the B terminal.

또한 공통단자(7)는 램프점등용 전원의 한쪽극에 결선되고, 전원의 다른쪽 극성은 외부조건 회로의 출력접점을 통해 해당램프의 외부입력단자에 접속되므로 각각 결선된다.In addition, the common terminal 7 is connected to one pole of the lamp lighting power supply, and the other polarity of the power supply is connected to the external input terminal of the corresponding lamp through the output contact of the external condition circuit.

한편, 외부의 조건회로-계전기로직, PLC 및 컴퓨터연산에 의해 구성될 수 있고 입력조건에 따라 램프의 점등전원을 출력한다. 이에 어떤램프에 해당되는 접점이 구성되면, 램프점등용 전원의 한쪽극성이 조건회로에서 구성된 접점을 통해 그램프의 외부입력단자를 거쳐서 램프(8)의 B단자로 인가되는데, 전원의 반대극성은 램프가 속한 모자이크 판넬의 공통단자(7)를 통해 상기 램프(8)의 A단자(몸통단자)로 항상 인가되므로 인해 폐회로가 구성되어 해당램프가 점등됨에 따라 표시장치로서의 역할을 수행하게 된다.On the other hand, it can be configured by external condition circuit-relay logic, PLC and computer operation and outputs the lighting power of the lamp according to the input condition. When a contact corresponding to a lamp is configured, one polarity of the lamp lighting power is applied to the B terminal of the lamp 8 via the external input terminal of the gram through the contact configured in the condition circuit. Since the lamp is always applied to the terminal A (body terminal) of the lamp 8 through the common terminal 7 of the mosaic panel to which the lamp belongs, the closed circuit is configured to serve as a display device as the lamp is turned on.

그러나 이와 같은 종래 소형백열전구 형태의 램프(8)를 사용할 경우 필요한 색상을 얻기 위해서 램프(8)의 유리구 표면에 유색의 코팅처리를 하는데 램프(8)자체의 열로 인하여 코팅부위에 변색 또는 흠이 자주발생되고, 여러가지의 색상을 필요로 하는 표시구간에는 색상에 따라 각각의 램프가 필요하게 되므로 설치공간을 많이 차지하게되며, 램프(8)의 짧은 사용수명(약1,000HR)으로 인하여 교체빈도가 높아서 유지 및 보수에 많은 비용이 소요되는 등의 문제점이 있었다.However, in the case of using the lamp 8 of the conventional small incandescent lamp type, in order to obtain the required color, the colored glass is coated on the surface of the glass bulb of the lamp 8, and the discoloration or flaw of the coating part due to the heat of the lamp 8 itself. This frequently occurs, and the display section that requires a variety of colors, each lamp is required according to the color, which takes up a lot of installation space, and the replacement frequency due to the short service life (about 1,000HR) of the lamp (8) There was a problem such as high costs for maintenance and repair.

본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 본 고안은 중앙집중열차 제어용표시 및 제어장치인 LDP의 신호용 소형모자이크 판넬에 설치되는 발광소자 표시기로서 다양한 색상을 나타낼 수 있도록 하여 설치공간을 축소시켜 판넬의 크기를 콤팩트화 할 수 있을 뿐만 아니라, 기기의 사용수명을 증대시킬 수 있는 발광소자표시기를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention is a light emitting device indicator installed in a small mosaic panel for the signal of the LDP which is a centralized train control display and control device to reduce the installation space by showing a variety of colors It is an object of the present invention to provide a light emitting device display which can not only compact the size of the panel but also increase the service life of the device.
