Description

플랫 조명 장치Flat lighting devices
본 발명은 조명 장치에 관한 것으로, LED 등의 발광 소자를 채용한 평판 형태의 플랫 조명 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device, and more particularly, to a flat lighting device having a flat plate type employing a light emitting element such as an LED.
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.

Do.
발광 유니트(300)는 본체 빔(112)에 형성된 발광 유니트 홈(3000)에 끼워짐으로써 도광판(106)의 측면에 배치된다. 발광 유니트 홈(3000)의 입구에는 발광 유니트(300)의 이탈을 방지하도록 라운드 형상으로 된 발광 유니트 인입부(3000r)가 형성된다. 판 스프링(340)은 발광 유니트 홈(3000)에 발광 유니트(300)가 탄성 지지되도록, 발광 유니트(300)의 배면을 가압하여 도광판(106)의 측면에 밀착시킨다. The light emitting unit 300 is disposed in the side surface of the light guide plate 106 by being fitted into the light emitting unit groove 3000 formed in the main body beam 112. At the entrance of the light emitting unit groove 3000, a light emitting unit inlet 3000r having a round shape is formed to prevent the light emitting unit 300 from being separated. The leaf spring 340 presses the rear surface of the light emitting unit 300 so as to elastically support the light emitting unit groove 3000 in the light emitting unit groove 3000 to closely contact the side surface of the light guide plate 106.
도광판(106)은 고정 클립(250)에 의하여 본체 빔(112)에 밀착 고정된다. 일 실시예로서, 고정 클립(250)은, 본체 빔(112)에 형성된 후크 고정 홈(1125)에 걸쳐지는 후크(251)와, 고정 클립 나사(430)가 관통되는 고정 클립 나사 관통구(438)와, 고정 클립 나사 관통구(438)에서 연장되는 고정 클립 나사 개구(436)를 구비한다.

As the light emitting device 310, a light emitting diode (LED), an organic light emitting diode (OLED), or the like may be employed. The light emitting device 310 consumes only about 1/3 to 1/10 the power of a general fluorescent lamp, Long life of over 50,000 hours is guaranteed. The light emitting device 310 is an environment-friendly light source because it does not contain a heavy metal such as mercury, unlike ordinary fluorescent light.
발광 소자(310)의 수명 기간 증대를 위하여 발광 유니트(300)에 마련된 방열 유니트가 발광 소자(310)의 열을 1차적으로 방열하며, 방열 유니트에 전달된 열은 본체 빔(112) 또는 덮개 빔(122)으로 확산되므로 발광 소자(310)가 열에 의하여 파손되지 않도록 한다.In order to increase the lifespan of the light emitting device 310, the heat dissipation unit provided in the light emitting unit 300 primarily dissipates heat of the light emitting device 310, and the heat transferred to the heat dissipation unit is transferred to the body beam 112 or the cover beam. Since it diffuses to 122, the light emitting device 310 is not damaged by heat.
본 발명의 플랫 조명 장치는 두께가 15~30mm 정도로 초슬림, 초경량으로 제작될 수 있으며, 고광택의 알루미늄 재질 또는 스테인레스 스틸 재질로 본체 프레임(110) 및 덮개 프레임(120)이 마련되므로 마감 처리가 깔끔하여 실내 인테리어에도 효과적이다.The flat lighting device of the present invention can be manufactured in a very slim, ultra-light weight of about 15 ~ 30mm, and the main frame 110 and the cover frame 120 is provided with a high gloss aluminum material or stainless steel, so the finishing treatment is neat It is also effective for interior.
이상에서 본 발명에 따른 실시예들이 설명되었으나, 이는 예시적인 것에 불과하며, 당해 분야에서 통상적 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 범위의 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호 범위는 이하에 기술되는 특허청구범위에 의해서 정해져야 할 것이다.Although embodiments according to the present invention have been described above, these are merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments of the present invention are possible therefrom.
