Abstract
A controlled-luminance lighting device comprising a fluorescent lamp (1), which extends longitudinally between a primary reflector (2) and a secondary reflector (3). The primary reflector (2) is formed by a plurality of cup-like elements (4) set alongside one another, having a generally parabolic shape, through which there extends the lamp (1), and the secondary reflector (3) is constituted by a tray-like element with a curved surface. The primary reflector (2) further includes a tile (9), which extends longitudinally between each pair of cup-like elements (4).
