초록
다양한 종류의 방전 셀이 존재하고 있지만, 공통적으로 모든 방전 셀은 보다 낮은 구동 전압에서 보다 높은 효율 특성을가지는 것을 우선적인 목표로 한다. 이러한 특성 개선을 위해 방전셀 내부의 방전 경로를 길게 하거나 구동 가스의 성분을변화시키는 연구가 많이 이루어진다. 본 논문에서는 2차원 유체 시뮬레이션을 이용하여 방전전극 사이의 간격에 따른 방전전압 (개시전압 및 유지전압) 및 휘도와 효율의 변화를 계산하였다. 또한, 다양한 하전입자와 여기입자 및 파장별 진공자외선의 변화를 살펴보고 휘도와 효율의 원인을 연구해 보았다.
Abstract
Although different types of discharge cells exist, in common it is the primary goal for all discharge cells to havelower drive voltages and higher efficiency characteristics. To improve these factors, many studies are conducted thatprolong the discharge path inside the discharge cell or change the composition of the working gas. In this paper, the two-dimensional fluid simulation was used to calculate the discharge voltage (firing voltage andsustain voltage) and the change in luminance and luminous efficacy according to the change in gap distance betweendischarge electrodes. In addition, we looked at changes in various charged particles, exciting particles and VUVparticles, and studied the causes of the resulting values.
