OPEN-ROOM LIGHTING DEVICE FOR OFFSETTING THE SOLAR-RAY IMPACT ZONE CROSSING A LENS

摘要

A lighting device (D) comprises a first part (P1), comprising a first partition (C1) partially delimiting a first space (E1) housing a lens (L) participating in a first illumination function and able to focus on solar rays substantially in a predefined part of the first partition (C1), and a second part (P2), comprising a second partition (C2) placed at least behind the predefined part. The first partition (C1) comprises an opening (OP) enclosing the predefined part so that the solar rays coming from the lens (L) end unfocused in a selected zone (Z) of the second partition (C2).
