A Study of Stability Analysis for Exit Light
Jong-Jin Jung, Seong-Ho SaKong
Abstract
In this study, Standards of Lighting Appliance and Standard of Model Approval and Inspection Technology for EXIT LIGHT are compared so as to analyze stability of a exit light which is fire product. Test items, which are not included in Standard of Model approval and Inspection Technology for EXIT LIGHT, are deduced from aforementioned comparison and analysis. Also the derived test items are experimented with a exit light. For a power factor correction, a power factor correction circuit is designed and power factor, crest factor, asymmetry ratio, luminance variation are analyzed. In order to show the validity of designed circuit, current waveform and voltage waveform are measured.
Key Words: Exit Light; Power factor correction; Crest factor; Lamp current; Luminance; Stability analysis
요지
본 연구에서는 소방제품인 유도등의 안정성 분석을 위하여 일반조명기기의 기준과 유도등의 형식승인 및 검정기술기준을 비교하였다. 유도등의 형식승인 및 검정기술기준에는 없는 시험항목을 도출하였다. 또한 도출된 시험항목으로 유도등을 대상으로 실험을 수행하였다. 역률을 보상하기 위하여 역률보상회로를 설계하였고 역률, 파고율, 비대칭율, 휘도의 변화를 분석하였다. 설계된 회로의 타당성을 검증하기 위하여 전압과 전류의 파형을 측정하였다.
핵심용어: 유도등; 역률보상; 파고율; 램프전류; 휘도; 안정성 해석
