LED LUMINAIRE

摘要

A LED luminaire has a first printed circuit board (PCB) and a second PCB spaced in such manner to generate an empty gap. Spacers are interposed between the first PCB and second PCB in such manner to keep them spaced. A printed circuit is obtained on the internal side of the first PCB. At least one LED is mounted on a pad of the printed circuit, in such manner that light emitted by the LED is subject to multiple reflections between the metal layers of the first PCB and second PCB and reflected light comes out of the gap, illuminating the surrounding space.

1. A LED luminaire comprising:
a first printed circuit board (PCB) and a second PCB spaced in such manner to generate an empty gap and identify, in each PCB, an internal side faced towards the gap and an external side faced outwards, each PCB having a transparent substrate, the first PCB having a reflecting metal layer on the internal side and on the external side, the second PCB having a reflecting metal layer on the internal side and/or on the external side; spacers interposed between said first PCB and second PCB in such manner to keep them mutually spaced; a printed circuit obtained on the internal side of said first PCB; at least one LED mounted on a pad of said printed circuit, in such manner that light emitted by said LED is subject to multiple reflections between the metal layers of said first PCB and said second PCB and reflected light comes out of said gap, illuminating the surrounding space.
