Description

간판용 LED형광등{LED FLUORESCENT LIGHT FIXTURE FOR SIGNAGE}LED FLUORESCENT LIGHT FIXTURE FOR SIGNAGE

본 발명은 LED등기구에 관한 것으로, 특히 전체적인 휘도의 균일도를 높일 수 있는 간판용 LED형광등의 개량에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an LED lamp, and more particularly, to an improvement of a LED fluorescent lamp for a signboard, which can increase the uniformity of the overall luminance.

요즘에는 대부분의 가정이나 사무실에서 형광등을 조명기구로 사용하고 있다. 형광등은 진공 유리관에 수은 및 아르곤 가스를 주입하고 유리관 내벽에 형광물질을 도포하여 수은 방전으로 생기는 자외선이 형광물질을 자극하여 가시광선으로 바뀌는 것을 이용한 조명기구이다.Nowadays, most homes and offices use fluorescent lights as lighting fixtures. A fluorescent lamp is a lighting device that injects mercury and argon gas into a vacuum glass tube and applies a fluorescent material to the inner wall of a glass tube, and ultraviolet rays generated by mercury discharge stimulates the fluorescent material to turn into visible light.

형광등은 백열등에 비해 전력소비가 적고 효율이 좋으며 긴 수명시간을 갖는 특징이 있다. 그러나 공급되는 전압이 높은 경우 형광등에서 흑화현상이 진행되어 수명이 짧아지고 낮은 전압이 인가되는 경우 형광등이 점등되지 않는 단점이 있다. Fluorescent lamps are characterized by lower power consumption, better efficiency and longer lifetime than incandescent lamps. However, when the supplied voltage is high, the blackening phenomenon progresses in the fluorescent lamp to shorten the lifetime, and when the low voltage is applied, the fluorescent lamp does not turn on.

이러한 단점을 가진 형광등을 대신하되 최근에는 저전력, 장수명, 및 친환경성의 장점을 갖는 LED를 광원으로 하는 LED형광등이 보급되고 있고 있다. In recent years, LED fluorescent lamps using LEDs as light sources having advantages of low power, long life, and environment friendliness have been replaced with fluorescent lamps having such disadvantages.

LED는 다른 광원들과 달리 수은이 함유되지 않은 친환경 광원인 바, 휴대폰용 백라이트, LCD TV용 백라이트, 차량용 램프, 및 일반 조명 등에 사용되는 차세대 광원으로 널리 각광받고 있다. 또 LED는 전력을 빛으로 변환시키는 효율이 뛰어나고, 현재 사용되고 있는 형광등이나 백열등에 비해 단위 전력대비 빛의 효율이 월등히 높아 경제성이 뛰어나며 저전압으로도 원하는 만큼의 광량을 얻을 수 있어 안전성이 뛰어나므로 조명등으로의 사용이 점차 증가하고 있는 추세이다.Unlike other light sources, LEDs are widely regarded as a next generation light source for mercury-free environment-friendly light sources, cell phone backlights, LCD TV backlights, vehicle lamps, and general lighting. In addition, the LED has excellent efficiency of converting power into light, and the efficiency of light compared to the fluorescent lamps or incandescent lamps being used is much higher than that of the currently used fluorescent lamps or incandescent lamps. Is increasingly used.

그런데 LED형광등은 LED의 빛직진성 때문에 LED칩소자가 향하는 전방 120°로만 빛이 편중되어서 나오므로 후방이나 측방으로의 조명 분포가 어려워 그림자를 형성하는바, 전후방이나 측방까지의 조명을 비춰주어야 하는 간판용 LED형광등으로 사용하기에는 어려움이 있었다. 두개의 LED형광등을 양쪽을 향하게 배치하게 되면 비용이 더 들고 빛이 골고루 확산되지 않는 단점이 있다. However, since the LED fluorescent light is emitted only by 120 ° in front of the LED chip device due to the straightness of light of the LED, it is difficult to distribute the light to the rear side or the side direction and forms a shadow. It is difficult to use the LED as a fluorescent lamp. If two LED fluorescent lamps are arranged facing to each other, there is a disadvantage that the cost is higher and the light does not spread evenly.

또 LED형광등은 LED칩이 어레이 형태로 배열되어 있어 LED칩이 한두개 고장이 나면 해당 부분에 뻐금히 그림자가 생기게 되어 간판 조명효과를 떨어뜨리는 단점이 있었다.In addition, the LED fluorescent lamps have a disadvantage in that when the LED chips are arranged in an array form, if one or two LED chips are broken, a shadows are easily formed on the corresponding portions, thereby deteriorating the signboard lighting effect.

간판용 LED형광등의 경우에는 220V 교류전원을 이용하는데 이 경우에는 LED칩이 한개 고장나면 다른 LED칩들을 포함한 LED모듈의 LED조명 전체가 꺼져버리는 단점이 있다. In the case of a LED fluorescent lamp for a signboard, a 220V AC power source is used. In this case, if one LED chip fails, the entire LED lighting of the LED module including the other LED chips is turned off.
