PROBLEM TO BE SOLVED: To provide a bright light for footing free from glare even with increased intensity of a light source by providing an irradiation opening of a light body with a translucent cover made of a shading louver plate member for permitting emission of light within a certain range. SOLUTION: A shading louver plate member 30 of a translucent cover 20 comprises a large number of minute louver film strips installed in the center of a film parallel to each other and sandwiched with 0.87-1.3mm thick transparent polycarbonate plastic sheets. A light beam c-c of a light source 15 coming out of an irradiation opening 7 of a lamp body 5 embedded in an attachment surface 25 such as a wall comes out from the upper part of the cover 20 approximately parallel to a floor surface 27. A light beam d-d coming out of the lower part of the cover 20 irradiates a ground surface. Therefore, light of the light source 15 does not reach human eyes directly. Therefore, light intensity may be increased without giving glare feeling to humans. |
