일반적으로, 발광다이오드(LED: Light Emitting Diode)는 전류 인가에 의해 P-N 반도체 접합(P-N junction)에서 전자와 정공이 만나 빛을 발하는 소자로서, 통상 LED 칩이 탑재된 패키지의 구조로 제작되며, 흔히 'LED 패키지'라고 칭해지고 있다. 위와 같은 LED 패키지는 일반적으로 인쇄회로기판(Printed Circuit Board: 이하, 'PCB'라 한다) 상에 장착되어 그 인쇄회로기판에 형성된 전극으로부터 전류를 인가받아 발광 동작하도록 구성된다.In general, a light emitting diode (LED) is a device in which electrons and holes meet and emit light at a PN junction by applying an electric current, and are generally manufactured in a package structure in which an LED chip is mounted. It is called 'LED package'. The LED package as described above is generally mounted on a printed circuit board (hereinafter, referred to as a PCB) and configured to emit light by receiving a current from an electrode formed on the printed circuit board.
LED 패키지를 이용한 LED 면 조명에 있어서, 다수의 LED 칩으로부터 발생한 열은 LED 패키지의 발광 성능 및 수명에 직접적인 영향을 미친다. 그 이유는 LED 칩에 발생한 열이 그 LED 칩에 오래 머무르는 경우 LED 칩을 이루는 결정 구조에 전위(dislocation) 및 부정합(mismatch)을 일으키기 때문이다.In LED side lighting using LED packages, the heat generated from multiple LED chips has a direct impact on the light emitting performance and lifetime of the LED package. The reason is that heat generated in an LED chip causes dislocations and mismatches in the crystal structure of the LED chip when the LED chip stays in the LED chip for a long time.
한편, LED 면 조명은 다수의 LED 소자로 형성되므로, 발열은 직접적으로 수명문제와 연결된다. 그러나, 현재로서는 냉각팬과 방열판의 구조 등을 이용한 방식외에는 특별히 대안이 없는 현실이다. On the other hand, since the LED surface lighting is formed of a plurality of LED elements, heat generation is directly connected to the life problem. However, at present, there is no special alternative except for the method using the structure of the cooling fan and the heat sink.
이런 방열판은 원가의 상승을 유도하는 단점이 있으며, 냉각팬은 지속적인 사용시 고장 등의 경우 치명적으로 LED 소자가 손상되는 문제점이 있다.Such a heat sink has a disadvantage of inducing an increase in cost, and a cooling fan has a problem in which an LED element is damaged in case of failure during continuous use.
이에 따라 해당 기술 분야에서는 고휘도의 LED의 특성을 이용할 뿐만 아니라, 보다 효과적인 방열이 수행되도록 함으로써, LED 면 조명 장치의 수명을 늘림과 동시에 사용자에게는 불편이 없도록 하기 위한 기술개발이 요구되고 있다.Accordingly, in the technical field, not only the use of high-brightness LED characteristics, but also more effective heat dissipation is carried out, so as to increase the lifespan of the LED surface lighting device and at the same time there is a demand for technology development to be comfortable for the user.
