Abstract

In the 21st century, white light-emitting diodes (LEDs) are widely used as backlighting for liquid crystal displays and as a light source for general illumination. However, white LEDs used in lighting often use a single yellow phosphor on top of a blue LED chip, which lacks the ability to reproduce natural colors in objects under conventional illumination accurately. Recently, researchers have been actively working on realizing high color-rendering lighting by incorporating red quantum dots to improve the spectrum in the long-wavelength band, which is deficient in conventional white LEDs. In particular, how to develop and apply remote quantum dot components to ensure long-term reliability is currently under active research. This paper introduces recent research on remote quantum dot components and the current status of developing high color-rendering lightings with them. Especially, we focus on various factors that are important to consider in optimizing the optical structure of the quantum dot components and discuss the future directions and prospects of research for high color-rendering lighting technology.

일반 백색 LED의 연색성을 보완하기 위해 적색 양자점을 선택적으로 활용함으로써 고연색성 조명을 구현하는 연구가 최근 활발하다. 본 논문에서는 최근 이루어지고 있는 원격 양자점 부품 연구 및 이를 활용한 고연색성 조명 개발의 현황에 대해 소개한다. 특히 양자점 부품이 배치되는 조명의 광구조 최적화에 있어서 중요하게 고려해야 할 다양한 요소를 집중적으로 논의함으로써 향후 고연색성 조명 연구의 방향 및 전망까지 다루고자 했다.
