Abstract
The interest in development on luminaires which are available up to is surging as demands in vessels navigating a north pole route increase. A conventional incandescent lamp used in vessels is operated stably at , but many countries including Korea have eliminated the use of incandescent lamps gradually because of its low luminous efficacy. In this paper, therefore, to develop the LED luminaires with high-efficiency, long lifetime that enables to substitute for incandescent lamp, it has studied about cryogenic characteristics of LED packages, bulbs, driving circuit and power supply. This experiments were carried out according to standards IEC 60945-8.4.1. Temperature range is from to , and the light output depending on ambient temperature. It showed that, based on , light output of a CFL decreased by 80% of CFL at while each increased 12% of LED bulbs and 16~19% of LED packages at .
