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. In other words, by converting the ballast power provided in the fluorescent lamp socket already installed into DC power required by the LED and supplying it to the LED, the ballast can be used without removing the ballast from the fluorescent lamp socket already installed or installing a separate socket. It relates to an LED lighting lamp that can be used in a fluorescent lamp socket having.
백열전구에 비하여 눈부심이 적고 발광 효율이 높으며 수명이 길어 많이 사용하는 조명 기구의 하나로 형광등이 있다. Compared to incandescent bulbs, there is less glare, high luminous efficiency, and long life, so one of the lighting fixtures used is fluorescent lamp.
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. This fluorescent lamp uses light from gas or gas discharge as a light source. A small amount of mercury vapor and argon gas for easy discharge are sealed in a vacuum glass tube, and then electrodes are attached to both ends.
이렇게 구성된 형광등은 열로 인한 손실이 적어 효율이 높고, 수명도 길다.The fluorescent lamp thus constructed has a high efficiency due to less loss due to heat and a long lifespan.
이러한 형광등은 부성저항특성을 갖는 수은방전관의 일종으로 전원만 공급할 경우 점등이 이루어지지 않고 점등을 유도하고, 점등 후 안정적으로 전원을 공급하기 위한 수단으로 안정기가 구비되어 있다. Such a fluorescent lamp is a kind of mercury discharge tube having negative resistance characteristics. When the power supply is only supplied, the fluorescent lamp is provided with a ballast to induce lighting and stably supply power after the lighting.
즉, 안정기를 설치하여 초기에는 형광등의 점등에 필요한 방전개시 고전압을 인가해주고, 점등 후에는 안정적인 전압과 전류가 공급되게 하였다. That is, a ballast was installed to initially apply a high discharge start voltage required for lighting a fluorescent lamp, and then a stable voltage and a current were supplied after lighting.
