Lighting device (1), comprising: a first reflector (4) that is fixed to a support structure (2), extends in a longitudinal direction (X) symmetrically with respect to a middle plane (±) parallel to the longitudinal direction (X), and is equipped with at least two first concave surfaces (5) extending symmetrically from the middle plane (±) from a common ridge (6) positioned at the middle plane (±); a plurality of LEDs (3) fixed to the support structure (2), positioned aligned with one in front of the ridge (6) of the first reflector (4), emitting first beams of light rays onto the first concave surfaces (5), which reflect them with second beams of light rays propagating symmetrically away from the middle plane (±) prevalently along light propagation directions (Y) perpendicular to the middle plane (±); Moreover, the lighting device (1) comprises two second reflectors (7) mechanically connected to the support structure (2), and each positioned outside of the respective first concave surface (5) of the first reflector (4) away from the middle plane (±) along the light propagation directions (Y). Each of the second reflectors (7) extends with longitudinal extension parallel to the longitudinal direction (X) and is equipped with at least one second concave surface (8) arranged to intercept the second beams of light rays, which reflects with third beams of light rays. |
