- Abstract
- 본 논문에서는 차세대 광원인 LED(Light Emitting Diode)를 Simulation하여 BLU(Back Light Unit)에 최적화 된 구조로 설계하여 진행 분석 하였다. 차세대 광원인 LED는 1962년 GaAsP 화합물 반도체를 이용한 Red LED가 상품화된 것을 시작으로 휴대전화기에 탑재하는 액정 패 널의 Backlight광원을 중심으로 착실하게 확대해 왔다. 현재 LED는 드디어 여명기에서 성장기로 들어왔다. 최근 LED 광원의 적용은 노트북이나 액정 모니터, 중대형 BLU 광원에 다양하게 적용되고 있다.또한 미래광원으로서 조명기기에 적용을 위하여 많은 개발이 이루어지고 있으며, 실제 조명 광원으로 채용되어 시장에 제품이 출시되고있다. LED 광원을 제작 하기 위하여 현재 BLU 광원으로 적용되고 있는LED 제품의 광 특성을 분석하였고, LED Chip의 형태 및 위치 LED내부 Reflector등에 따른 광도(Luminous Intensity) 및 전광속(Total Flux), 지향특성(Radian Angle Character)을 Optic Simulation을 이용하여 모의 시험을 수행하였다. Optic Simulation 결과는 LED 광원의 광도, 전 광속, 지향특성, 조도 분포에 대하여 해석을 진행 하였으며, 본 LED 특성을 가지고 BLU에 적용하여 실제 LGP에 입사되는 광 효율 및 분포도에 대하여 검증 하였다.
- Alternative Abstract
- In this thesis I have attempted to analyze new generation a source of light LED(Light Emitting Diode) with Simulation and optimization design for BLU. New generation a source of light LED is beginning with commercialized Red LED which is made by GaAsP compound semiconductor, and has been developed focusing on liquid crystal panel, a source light of Backlight. Nowadays, LED in enter the period of growth form dawning. The recent action of LED is various, it’s applied to laptop, LCD Monitor, and Large & Medium sized light source of BLU. Also, there are a large number of development project to apply lightning equipment for future generation of source of light, and few items are already released as lighting equipment on the market. To produce a Source of light LED, I have analyzed Optical characteristics for LED Item which is applied the light source of BLU, and did trial examination shape and position for LED Chip, Luminous Intensity form the inside Redlector, Total Flux, Radian Angle Character on Optic Simulation. Result of Optic Simulation is made from analyzing Luminous Intensity, Total Flux, and luminance distribution for source of LED lighting, and with this LED characteristics which I applied to BLU, I verified Efficiency and distribution chart for actual exposed light on the LGP.
