To provide a marine LED lighting device that can sufficiently dissipate heat generated from an LED board and a power supply board without using metal components that come into contact with outside air.SOLUTION: Light emitted from an LED component 27 arranged in an interior space S enclosed by a body 2 and a glove 3 is transmitted through the glove 3 and diffused to an outside. The marine LED lighting device comprises: a power supply board 4 which is arranged on a mounting base 7 of the body 2 across a first space S1 and has a semiconductor component 22 mounted thereon; and an LED board 5 which is arranged on the power supply board 4 across a second space S2 and has the LED component 27 mounted thereon. A heat-dissipating connection member 6 arranged in the first space S1 and having one end attached to the mounting base 7 of the body 2 and the other end in contact with the semiconductor component 22 mounted on the power supply board 4 is provided. A heat-dissipating board 12 facing the first space S1 is provided in the mounting base 7 of the body 2. A heat-dissipating plate 29 facing the second space S2 is provided in the LED board 5.SELECTED DRAWING: Figure 2
【課題】外気に接触する部品に金属製のものを用いずに、ＬＥＤ基板及び電源基板から発生する熱を十分に放熱することができる船舶用ＬＥＤ照明装置を提供する。【解決手段】本体２とグローブ３とで囲まれた内部空間Ｓに配置されたＬＥＤ部品２７から発光する光をグローブ３を透過させて外部に拡散する。本体２の取付ベース７に第１空間Ｓ１を隔てて配置され、半導体部品２２が実装された電源基板４と、電源基板４に第２空間Ｓ２を隔てて配置され、ＬＥＤ部品２７が実装されたＬＥＤ基板５とを備える。第１空間Ｓ１に配置され、一端が本体２の取付ベース７に取り付けられ、他端が電源基板４に実装された半導体部品２２に接触している放熱連結部材６が設けられている。本体２の取付ベース７に、第１空間Ｓ１に面する放熱基板１２が設けられている。ＬＥＤ基板５に、第２空間Ｓ２に面する放熱板２９が設けられている。【選択図】図２
