To provide an LED lighting fixture capable of efficiently melting snow and frost attached to a translucent cover without impairing the degree of freedom in design of a device to which it is applied.SOLUTION: An LED lighting fixture includes a case body, a translucent cover, and a plurality of LED modules. The LED module includes: a plurality of bus bars arranged side by side via an interval on the same plane; an insulating film or an insulator of an insulator layer for connecting a plurality of bus bars; a singular or a plurality of LED elements mounted on a first surface side connection part of a part of the bus bars; an electric connection member for electrically connecting the LED element and the first surface side connection part of the remaining bus bars; and a highly heat conductive frame body fixed to the insulator so as to surround the plurality of LED elements in a plan view. Between the frame body and the cover, the highly heat conductive elastic member is interposed, and at the cover, a highly heat conductive heat conductor is provided at least at a part of a region with which a first side on one side of the elastic body is engaged.SELECTED DRAWING: Figure 4 【課題】適用される装置の設計自由度を損なうことなく、透光性カバーに付着した雪や霜を効率的に融解可能なＬＥＤ灯具を提供する。【解決手段】本発明に係るＬＥＤ灯具は、ケース本体、透光性のカバー及び複数のＬＥＤモジュールとを備える。ＬＥＤモジュールは、同一平面内に間隙を介して並列配置された複数のバスバーと、複数のバスバーを連結する絶縁性フィルム又は絶縁層の絶縁体と、一部のバスバーの第１面側接続部に装着された一又は複数のＬＥＤ素子と、ＬＥＤ素子及び残りのバスバーの第１面側接続部を電気的に接続する電気接続部材と、平面視において複数のＬＥＤ素子を囲繞するように絶縁体に固着された高熱伝導性の枠体とを有する。枠体及びカバーの間には高熱伝導性の弾性部材が介挿され、カバーには弾性部材の一方側の第１側が係合される領域の少なくとも一部に高熱伝導性の熱伝導体が設けられている。【選択図】図４
