종래의 조명 장치는 백열등이나 형광등을 광원으로 이용하므로 광도가 낮고 광전달의 균일성이 떨어져 조명 품질이 상대적으로 떨어진다. Conventional lighting devices use incandescent or fluorescent lamps as a light source, so the luminous intensity is low and the uniformity of the light transmission is reduced, resulting in relatively poor illumination quality.
이에 비하여 발광 다이오드(LED), 유기 발광 다이오드(OLED) 등의 발광 소자는 종래의 광원에 비하여 소형이고, 무엇보다 매우 얇게 제작할 수 있으며, 수명은 연장되고 전기 에너지가 빛 에너지로 직접 변환되기 때문에 소비 전력이 적게 들고 효율성이 매우 높다.On the other hand, light emitting devices such as light emitting diodes (LEDs) and organic light emitting diodes (OLEDs) are smaller than conventional light sources, and can be manufactured to be very thin, and, as such, are consumed because their lifespan is extended and electrical energy is directly converted into light energy. Low power and very high efficiency.
예를 들어 n형 반도체에서 주입된 전자가 P형 반도체 속에 다수 존재하는 정공과 재결합함으로써 빛이 발생하는 LED는 전력 소모량이 일반 형광등의 1/3 ~ 1/10 수준에 불과하며, 수명 기간이 50,000시간 이상으로 일반 램프 대비 6배 이상의 수명을 갖는다.For example, LEDs that generate light by recombining electrons injected from n-type semiconductors with a large number of holes in P-type semiconductors consume only 1/3 to 1/10 the power of ordinary fluorescent lamps and have a lifetime of 50,000. More than six times longer than ordinary lamps.
따라서, 실내 장식을 필요로 하는 일반 가정이나, 낮은 전력 소모 및 고휘도를 요구하는 산업 현장에 발광 소자를 광원으로 하는 평판형 조명 장치를 널리 보급할 필요성이 있다. Therefore, there is a need for widespread use of flat panel lighting apparatuses using light emitting elements as light sources in general homes that require interior decoration or industrial sites requiring low power consumption and high brightness.
