Abstract
A lighting device, e.g. for wallwashing lighting applications, includes a linear array of light radiation emitters including a light radiation source, e.g. a LED source, a light guide member having a first end coupled with the radiation source and a second end to emit light radiation guided by the guide member along a guide axis, as well as an optical system to receive light radiation from the light guide member and project outgoing light radiation from the lighting device. The light guide members of the light radiation emitters in the array are arranged with their second ends aligned in a longitudinal direction of the array, and with their light guide axes lying in a common plane angled to a reference plane. The optical systems of the light radiation emitters in the array produce outgoing light radiation beams having higher angles to said reference plane than the corresponding input beams.
