  • For turn on high pressure sodium vapor lamp, Starting Voltage is very important factor. This starting voltage supply to high pressure sodium vapor lamp as electric discharge lamp, Electric field is producted in electric discharge tube, So accelerative electron collide against vapor atom and second electron is generated, And rapidly the current flow to electric discharge tube. This starting voltage is high voltage and source for melting contact that relay is according as turn on/off high pressure sodium vapor lamp. Consequently, This paper propose that the prevention of melting contact in accordance relay of controller for turn on/off high pressure sodium vapor lamp.

  • 고압방전등을 점등하기 위해서는 고전압의 시동전압이 필요하게 되는데, 이러한 시동전압은 고압력의 나트륨램프에서도 필요하게 된다. 자기장은 전기 방전튜브에서 만들어지게 되며 증기 원자에 대한 전자충돌이 가속화되면서 2차 전자가 발생하고 전기 방전튜브에 전류가 급속도로 흐르게 되며, 나트륨램프의 제작회사마다. 서로 다른 램프의 수명 및 교환시점도 서로 다르다는 것을 본 논문의 연구과정에서 발견하게 되었다. 본 논문에서는 LabVIEW소프트웨어패키지를 사용 중인 나트륨램프의 교환시점의 알고리듬을 제안한다.

  • This study was conducted to research how UCD(Ultra Constant Discharge) lamp lighting affects plant cultivation. To get the results within a short time, lettuce seedling was selected as a plant and nutrient hydroponic beds were used in a dark room for 100% artificial lighting. Two beds were installed for same distance lighting condition with UCD lamp and Hi-pressure Sodium lamp each and another two beds were installed for same light intensity condition with each type of lamp. After 15 days of cultivation, for both conditions, the yields under UCD lamp were weighed more than that under Hi-pressure Sodium lamp. The result can be analyzed that the spectrum of UCD lamp having near sunlight characteristic is much superior to that of Hi-pressure Sodium lamp having a line spectrum characteristic on yellow and red wavelengths for plant cultivation.

  • 터널구조물의 특성상 터널조명은 일반 도로의 조명과 달리 주간에도 조명이 필요하므로, 터널 유지관리 비용 가운데 터널조명을 위한 전력요금은 가장 높은 비율을 차지하고 있는 것으로 알려져 있다. 따라서 유지비용 절감 등을 위하여 터널조명을 낮은 소비전력, 장수명 등의 장점이 있는 LED램프로 교체 중에 있다. 본 연구에서는 기존 터널조명이 고압나트륨램프인 10개소 터널을 대상으로 터널조명 광원을 LED램프로 교체 시 효과 분석을 위하여, 광원 교체 전·후 터널 조도측정결과 및 1년간의 월별 전력사용량을 조사하였다. 터널조명 광원을 고압나트륨램프에서 LED램프로 교체 후 조도는 27.9~490% 향상되었으나, 터널조명용 전력사용량은 평균 47.1% 감소한 것으로 나타났다.

  • This paper describes a design of the external-exciting electronic ballast for 100W high pressure sodium lamp. The ballast is consists of the full-bridge inverter and an external-exciting control circuit. L and C values of an equivalent L-C series resonant circuit are calculated analytically. The electrical output characteristics of the ballast, such as voltage, current etc., are simulated by Pspice. The experimental results from high pressure sodium lamp system with the ballast we developed are shown to be consistent with the simulated results.

  • This paper introduces the electronic ballast for high pressure sodium (HPS) lamps which provides power regulation during the whole lamp life without using a closed-loop power control system, in spite of large variations of lamp characteristics resulting from lamp aging. The structure of the electronic ballast and the parameters of HPS lamps are described. A mathematical model for the ballast is developed and used for the design and analysis of the ballast. A design procedure is presented to design the ballast which provides intrinsic power regulation over the whole lamp life. To improve the technical specifications of the ballast, the practical and standard constraints are considered in the design. According to the design procedure, an electronic ballast for 250-W HPS lamps is designed. All theoretical analyses are verified with the help of a semi-industrial experimental setup. The results validate that the designed ballast provides power regulation during the whole lamp life.
