A LED luminaire comprises: a first printed circuit board (PCB) (1) and a second PCB (l1) spaced in such manner to generate an empty gap (I), spacers (6) interposed between said first PCB (1) and second PCB (l1) in such manner to keep them spaced, a printed circuit obtained on the internal side (3) of said first PCB (1), at least one LED (4) mounted on a pad of said printed circuit, in such manner that light (Rl) emitted by said LED (4) is subject to multiple reflections between the metal layers of said first PCB (1) and said second PCB (l1) and reflected light comes out of said gap (I), illuminating the surrounding space. |
