Abstract

A lighting device (1) comprises a shell (2) enclosing a reflecting body (5) comprising a plurality of hollow, paraboloid-shaped housings (6), each able to accommodate, in a position substantially close to the focus of the paraboloid, a light source (4) such as a LED, for example, supported on a plate (3), the shell (2) being covered by a light-transparent cover (7).
