INSNA에서 제시하고 있는 환경등급에 따른 광속유지율 산정법에 기초하여, 각 고속도로의 교통량, 주변 지역의 오염 정도에 따라 세분화된 보수율을 산정하는 방법을 제시함으로써 고속도로 조명설계에 있어서 보수율 적용을 손쉽게 할 수 있도록 하였다. 또한, 그러나 기존의 보수율 개념만 가지고는 실제적인 광손실률 값을 얻을 수 없으므로 장치적용률로서 0.9 정도를 고려해야 실제 현장에서 적용하고 있는 보수율에 근사한 값을 얻을 수 있었다. It is required to determine proper values for the maintenance factor according to traffic volume in the freeway lighting design. This paper presents a simple method to seperate of the effect of surrounding environment and that of traffic volume, which is based on the IESNA treatment with additional assumptions on their effects. Furthermore, it is found that prevailing concept for the maintenance factor does not necessarily yield a proper value for light loss factor, so that an additional factor of 0.9 should be included as an equipment factor.factor.

Recently, a method of magnetically-enhanced discharge columns is considered to increase the luminous efficacy of discharge lamps, which is based upon the fact that the diffusion motion of charged particles in the discharge column strongly depends on the applied magnetic fields. This study investigates the effect of applied transverse magnetic fields on the light output of low-pressure Hg-Ar discharge. As a result, it is found that the electric field in the positive column increases according to the applied magnetic field, which causes an increase in the total light output. And this effect is much more pronounced upon the spectral line originating from the higher levels.
