Abstract (en)
[origin: EP1672274A1] The luminaire has a support case receiving a linear fluorescent lamp, and lateral reflectors (R1, R2) transversely receiving multiple reflection plates (1). Each plate has concave and convex faces with a transversal section in a horizontal plane, where section`s profile distributes luminous flux, decreases brightness of a vertical plane along a longitudinal axis, and increases brightness in transverse and intermediate planes. The plates have upper and lower edges that are rectilinear or that present a radius of curvature. The plates are not touched between them in a vertical longitudinal section of the lamp.
