PROBLEM TO BE SOLVED: To enable a reflection member of light-emitting diode not only to be applied as a display element having a narrow frontward or rearward width but also to be sufficiently acknowledged in sight at both far-away position and near position.SOLUTION: This invention relates to a reflection member of light-emitting diode that is used in a display lamp for reflecting light of light-emitting diode arranged with optical axis being directed in a vertical direction in a cross direction, a plurality of triangle prismatic shape prisms having three slant surfaces of triangle section at the rear surface of translucent plate arranged in a vertical direction are arranged in a vertical direction while one of those slant surfaces is parallel to each other and other one slant surface is arranged in a vertical direction perpendicular to the translucent plate, the slant surface arranged perpendicular to the translucent plate is applied as an irradiation surface of the light-emitting diode and at the same time a condenser lens is arranged at an arranging position of the prism of the translucent plate to which light is irradiated. |
