PURPOSE:To prevent light beams of a lamp from being incident to eyes directly by forming the face of a reflection plate along the lamp in the form of convex shape toward an opening from the inside of a luminaire, and forming a reflection face for controlling a light beam shutting angle with the inclined angle of a tangential line from the lamp with respect to the curved surface. CONSTITUTION:An iluminaire device is provided with reflection plates 13 having an opening 1 and lamp units held between the plates 13, wherein the face of the plate 13 along the lamp unit is formed in a convex shape toward the opening 11 from the inside to form a reflection face to control the light beam shutting angle by the inclined angle of the tangential line from the lamp with respect to the curved face. It is thus possible to change the inclined angle to prevent the beams from the lamp units from being incident to eyes directly, and to prevent decrease in illumination directly applied downwards with an increased illumination opening of the main body of iluminaire and with less decrease in the light amount. |
