Description

절전형 냉음극 형광램프의 점등 방법{method for lighting cold cathode fluorescent lamp with saving electric energy}[0001] The present invention relates to a cold cathode fluorescent lamp,

본 발명은 절전형 냉음극 형광램프의 점등 방법에 관한 것으로서, 더욱 상세하게는 하나의 안정기를 사용하여 다수의 냉음극 형광램프를 용이하게 점등시킬 수 있어 절전 효과뿐만 아니라 램프의 수명이 길어져 내구성이 향상되는 절전형 냉음극 형광램프의 점등 방법에 관한 것이다.The present invention relates to a method for lighting a cold cathode fluorescent lamp, and more particularly, to a method for lighting a cold cathode fluorescent lamp using a single ballast, which can easily light a plurality of cold cathode fluorescent lamps, thereby improving the durability And a lighting method of the power saving cold cathode fluorescent lamp.

전기와 백열전구가 발견, 발명된 후 지속적으로 발전해온 조명기구에서 현대에 들어 형광등의 밝기와 에너지를 대적할만한 조명기구는 흔치 않다.In lighting fixtures that have been developed continuously since electricity and incandescent lamps were discovered and invented, lighting fixtures are not common enough to oppose the brightness and energy of fluorescent lamps in modern times.

백열등을 대체하여 발달해온 형광등은 흔히 삼파장등 이라는 굴곡형 형광등으로 발전하여 현재 가장 널리 사용되고 있으며, 근래에 와서 반도체 소자의 개발 등에 따른 기술의 개발로 LED (발광다이오드)를 조명에 많이 사용하고 있다.Fluorescent lamps developed by replacing incandescent lamps have been developed into bendable fluorescent lamps, such as three-wavelength lamps, and are now widely used. Recently, LEDs (light emitting diodes) have been widely used for lighting due to development of technologies for developing semiconductor devices and the like.

상기한 LED는 밝기에 대비하여 기존의 백열전구나 형광등에 비해 낮은 에너지 소모를 가지나 LED는 그 빛의 성질에 의해 청색광이라는 빛의 온도 7500K 로 발산하기 때문에 그 빛이 넓고 멀리 가지 못하는 단점이 있으며, 램프의 밝기가 너무 밝아 사용자의 눈이 부시는 등 문제점들이 나타나고 있다.The above LED has a lower energy consumption than a conventional incandescent lamp or a fluorescent lamp in contrast to brightness. However, since the LED emits blue light at a temperature of 7500K due to the nature of the light, The brightness of the eyes of the user is too bright.

또한 빛의 파장의 굴절에 의하여 물체의 색깔이 변질되어 보이는 등의 문제와 더불어 많은 발열에 의한 방열구조 등에 의하여 그 적용범위가 형광등 많큼 넓지 못하다.In addition, the color of the object is changed by the refraction of the wavelength of light, and the application range of the fluorescent lamp is not as wide as that of the heat dissipation structure due to heat generation.

그리고 본 발명에 사용되는 냉음극 형광 램프(CCFL cold cathode fluorescent lamp)는 기존의 형광등과 달리 필라멘트에 의한 발열 점등 방식이 아닌 고전압 유도 발광 방식을 사용한다.The CCFL cold cathode fluorescent lamp used in the present invention uses a high voltage induced light emission method instead of a heating light method using a filament, unlike a conventional fluorescent lamp.

다시 말해 필라멘트의 가열 없이 저온에서 점등되는 형광등에 사용하는 것으로 유리관 양끝에 전극이 있고, 내부에는 일정량의 수은과 아르곤, 네온 등의 혼합 가스가 들어 있으며, 유리관 내부 표면은 형광체가 도포된 일반 형광등과 동일한 구조와 원리를 갖는다. In other words, it is used for fluorescent lamps that are lit at low temperatures without heating the filaments. There are electrodes on both ends of the glass tube, and a certain amount of mercury, argon, neon, etc. are mixed in the inside of the glass tube. The inside surface of the glass tube is a general fluorescent lamp Have the same structure and principle.

일반 형광등은 가열에 의해 전자 방출이 시작되는 데 반해 냉음극 형광 램프는 두 전극에 가해진 고전압 전계에 의해 전자 방출이 일어나고 전자 방출이 시작되면 수은이 여기되어 자외선이 발산되며, 이 자외선이 방전관 벽의 형광체와 충돌하면서 가시 광선을 발산시키게 되는 것이다.In general fluorescent lamps, electron emission starts by heating. Cold cathode fluorescent lamps emit electrons by high voltage electric field applied to both electrodes. When electron emission starts, mercury is excited to emit ultraviolet rays. It collides with the phosphor and emits visible light.
