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).
Claims7
A controlled-luminance lighting device, comprising at least one fluorescent light source of a linear type (1), which extends longitudinally between a primary reflector (2) and a secondary reflector (3), wherein:
- 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 said light source (1);
- and
- the secondary reflector (3) is constituted by a tray-like element with a curved surface, the bottom wall (7) of which has cusps (8) in a position longitudinally corresponding to said light source (1).
