This paper presents information about the examples of the design on Illumination of Structures(LED Light Pipe forlighthouse) in Korea. We have applied illumination by flood-lighting or facade-lighting in place of the 57 lighthouses (offshore structures)and 4 beacons. The ways of illumination of structures are using direct illumination with LED, halogen lamps and metal halide lamps, andindirect illumination with LED non-neon lamps. The illumination of structures helps a observer to identify the Aids to Navigation and waterway. The fabricated LED Light Pipe is a transparent acrylic round bar and easy to install. The Light Pipe is arranged in two rows of LED (78ea). It can be connected in series. It has 4 colours(Red, Green, Yellow, White). We analyzed and the horizontal divergence angleof the LED light pipe is defined as the range with 50% of maximum luminous intensity. Also, we evaluated the conspicuity on the original lantern and LED Light pipe for lighthouse. The field experiment was conducted in ‘Yeosuguhang lighthouse’ in Yeosu-city (Korea). From the experimental results, it was confirmed that the fabricated LED Light Pipe is clearly distinguished.
