엘이디 면발광 조명기기의 라이팅 판넬구조{Lighting panel structure of LED luminous face liluminator}Lighting panel structure of LED luminous face liluminator

본 발명은 엘이디(LED; Light Emitting Diode) 면발광 조명기기에 관한 것으로, 특히 조명 조도를 향상시킨 엘이디 면발광 조명기기의 라이팅 판넬구조에 관한 것이다.The present invention relates to a light emitting diode (LED) surface emitting lighting device, and more particularly, to a lighting panel structure of an LED surface emitting lighting device having improved illumination intensity.

최근 들어 LED를 이용한 조명기기가 기존 램프조명을 대신하는 용도로 채택되는 사례가 증가하고 있는 실정이며, 이는 LED 자체의 고휘도, 오랜 수명, 고색순도 등의 성능향상뿐만 아니라, 기존 벌브를 이용한 램프조명을 통해서는 조명기기의 고품위 및 경박 단소화에 한계가 있기 때문이다.Recently, the use of LED lighting equipment has been increasingly used as a substitute for conventional lamp lighting, which is not only to improve the performance of the LED itself, but also to improve the performance of high brightness, long life, high color purity, and lamp lighting using existing bulbs. This is because there is a limit to the high quality and light weight of the lighting equipment.

이와 같은 부응 속에 측면발광 LED 조명기구는 다양한 조명기기뿐만 아니라, 각종 안전 및 교통 표지판 등으로 각광을 받고 있는바, 예를 들어 다각형 또는 원형 외곽 프레임에 LED가 등간격으로 배치되는 LED 스트립을 장착하고, 이 LED 스트립을 발광칩의 전선과 연결시키며, 상기 다각형 또는 원형 외곽 프레임으로 라이팅 판넬(Lighting panel)을 보유 지지하는 구조를 갖는다.In response to this, the side-emitting LED lighting fixtures are attracting attention not only for various lighting devices but also for various safety and traffic signs. For example, a polygonal or circular outer frame is equipped with LED strips at equal intervals. In addition, the LED strip is connected to the wires of the light emitting chip, and has a structure for holding a lighting panel in the polygonal or circular outer frame.

그러나 종래 측면발광 LED 조명기구에서 라이팅 판넬구조는 확산판에 도광판과 반사시트 및 백플레이트가 차례로 적층되어 이루어진 구조로 되어 있는바, 이러한 라이팅 판넬은 LED의 방사빛이 상기 라이팅 판넬의 도광판에 반사되어 조명 및 발광이 이루어지는데, 라이팅 판넬에서 빛 확산이 이루어져 조명하게 됨으로써 집광효율의 저하에 따른 조도 효율이 떨어지는 단점이 있었다.However, in the conventional side-emitting LED lighting fixtures, the lighting panel structure has a structure in which a light guide plate, a reflective sheet, and a back plate are stacked on a diffuser plate in turn. Illumination and light emission is made, the light is diffused from the lighting panel is illuminated to have a disadvantage in that the illuminance efficiency is lowered due to the reduction of the condensing efficiency.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 제안된 것으로, 조도효율의 향상이 이루어지는 엘이디 면발광 조명기기의 라이팅 판넬구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been proposed in view of the above-described conventional problems, and an object thereof is to provide a lighting panel structure of an LED surface light emitting lighting device in which illuminance efficiency is improved.

In the lighting panel structure of the LED surface-emitting lighting device is made, the lighting panel is a plurality of high-brightness sheet is embedded between the diffusion plate and the light guide plate, characterized in that the high-brightness sheet is arranged in a grid or the same arrangement.

상기와 같은 본 발명에 따른 엘이디 면발광 조명기기의 라이팅 판넬구조는 라이팅 판넬의 확산판과 도광판 사이에 복수 개의 고휘도 시트가 내장됨에 따라 LED 방사빛의 굴절률을 최대화시키어 난반사로 빛의 확산과 집광 효율을 강화시켜 결국, 조도효율의 향상을 가져오는 잇점을 갖는다.The lighting panel structure of the LED surface-emitting lighting apparatus according to the present invention as described above maximizes the refractive index of the LED emission light as a plurality of high-brightness sheets are embedded between the diffusion panel and the light guide plate of the lighting panel, thereby diffused light and condensing efficiency by diffuse reflection.
