dc.description.abstract Recently, the current characteristics of LED is important which is widely used in the kinds of display devices or lighting market. To develop this LED Dome Light, a LED dome light of ship using by reliability was investigated. Experiment is to identify the current characteristics Bare Chip of GaN according to the temperature. It was found that the VF(Forward Voltage) and luminous intensity were getting down when temperature increased. The wavelength of Blue chip was shifted long wavelength. Consequently, It was found that temperature of LED PN junction need to LED PN junction with less than 80 degrees and It should be that LED Dome Light's internal temperature designed below 50 degrees. LED Dome Light were designed to the following specifications. A LED spec of LED Dome Light was designed with luminous intensity of 7[cd], color temperature of 6000 ± 500 [K], Chip Q`ty of 3, Forward voltage of 3~3.2[V] and input current of 60[mA]. Also, upon investigating the thermal distribution of the unit module through a experiment of thermal for LED dome light. In this work, LED Dome Light regarding reliability analysis for the heat and vibration and when LED Light applied to a vessel resulting from an analysis of optical characteristics of the time. -
