PROBLEM TO BE SOLVED: To provide a ship's lamp capable of clearly defining an interface of a shading range with a shading wall within a narrow range without arranging a second shading wall.SOLUTION: This invention relates to a ship's lamp constructed such that a plurality of LEDs 49 on the same circumference with a center axis line O being a center and an angular range (360-&thetas;1) except an opening of an opening angle &thetas;1 with the center axis line O being a center is shaded by a shading wall S. The nearest LED 49 is arranged on a straight line L passing through the center axis line O and the edge of the shading wall S in such a way that its center may coincide with the straight line L and further it is set in such a way that light beam produced from another LED 49 may not be dispersed outside the opening from the straight line L. |
