안정기를 갖는 형광등 소켓에 사용할 수 있는 LED조명등{LED lamp usable fluorescent socket with the ballast} LED that can be used in fluorescent lighting ballasts socket with {LED lamp usable fluorescent socket with the ballast}

본 발명은 조명등에 관한 것으로 상세하게는 기존의 안정기를 갖는 형광등에 끼워 사용할 수 있는 LED조명등에 관한 것이다. The invention is in detail relates to a luminaire relates to a LED lamp that can be fitted to the fluorescent lamp with a conventional ballast.

즉, 이미 설치된 형광등 소켓에 구비된 안정기의 전원을 LED에서 요구하는 직류전원으로 변환하여 LED에 공급할 수 있도록 구성함으로서 이미 설치된 형광등용 소켓에서 안정기를 분리하거나 별도의 소켓을 설치하기 않고 사용할 수 있는 안정기를 갖는 형광등 소켓에 사용할 수 있는 LED조명등에 관한 것이다. That is, the stabilizer that can separate the ballast in a fluorescent lamp socket for an already installed or used without installing a separate socket by configuration converts the power to the ballast provided in the fluorescent lamp sockets already installed into DC power required by the LED can be supplied to the LED the present invention relates to LED lights that can be used in fluorescent lamps with socket.

백열전구에 비하여 눈부심이 적고 발광 효율이 높으며 수명이 길어 많이 사용하는 조명 기구의 하나로 형광등이 있다. Less glare than the incandescent lamp has a high luminous efficiency in one of the fluorescent lighting equipment commonly used long life.

이 형광등은 기체나 기체속의 방전에 의한 빛을 광원으로 이용한 것으로서, 진공유리관에 소량의 수은 증기와 방전을 쉽게 하기 위한 아르곤가스를 넣어 밀폐한 다음 양끝에 전극을 붙여 구성된다. The fluorescent lamp is configured as with the light by the discharge in the gas or gases as a light source, a putting argon gas to facilitate a small amount of mercury vapor and discharge in a vacuum sealed glass tube attached to the electrode, and then ends.

이렇게 구성된 형광등은 열로 인한 손실이 적어 효율이 높고, 수명도 길다. This is composed of a fluorescent lamp less loss due to heat, high efficiency, long life also.

이러한 형광등은 부성저항특성을 갖는 수은방전관의 일종으로 전원만 공급할 경우 점등이 이루어지지 않고 점등을 유도하고, 점등 후 안정적으로 전원을 공급하기 위한 수단으로 안정기가 구비되어 있다. This fluorescent lamp is provided with a ballast by means for deriving the light does not light up is made when only the power supply to the type of the mercury discharge tube has negative resistance characteristics, and stably supplying power after lighting.

즉, 안정기를 설치하여 초기에는 형광등의 점등에 필요한 방전개시 고전압을 인가해주고, 점등 후에는 안정적인 전압과 전류가 공급되게 하였다. In other words, by installing the ballast initially applying a high voltage necessary for the discharge start lighting of the fluorescent lamp haejugo, after lighting was so stable voltage and current is supplied.

이와 같이 구성된 형광등은 상기한 바와 같이 진공유리관을 이용하여 구성됨으로서 제조시 진공유리관이 충분히 밀폐되어야 함으로 제작에 많은 어려움이 있을 뿐만 아니라, 돌발적으로 점등이 되지 않는 경우가 있고, 수명이 다해갈 경우 깜빡거리는 문제가 있었다. Thus configured fluorescent lamps, as well as there are many difficulties in the production by a vacuum glass tube has to be fully closed during manufacture by being formed by using a vacuum glass tube described above, there is a sudden, if that is not light up, flashes when going with all the life the distance was a problem.
