Illumination unit

An illumination unit, comprising:

• a supporting structure (A1);
• a photovoltaic module (A) mounted to said supporting structure (A1);
• a ceiling light fixture (B) mounted to said supporting structure (A1), at an opposite side of said supporting structure (A1) with respect to said photovoltaic module (A);
• wherein:
• said ceiling light fixture (B) comprises a substantially planar wall and two side wings (B2) extending from opposite sides of said planar wall, said ceiling light fixture (B) further comprising:
• an electric storage unit (E) chargeable with electric power generated by said photovoltaic module (A);
• a housing seat comprising a plurality of spaces (C) for containing optical elements/means (C1) and integrated into a separate printed circuit board (F) made on a string (F1), wherein:
• said optical elements/means (C1) are connected with said ceiling light fixture (B) according to an arrangement matching/coinciding with said spaces (C), and wherein:
• said spaces (C) are punched in said substantially planar wall in proximity to a shaped line (B1);
• wherein said optical elements/means (C1) are power supplied by said photovoltaic module (A) and/or said electric storage unit (E);
• said ceiling light fixture (B1) further comprising:
• a control unit (D) including a timer device connected to said printed circuit board (F), said timer device being configured to intermittently activate said optical elements/means (C1) at programmable time intervals, said control unit (D) further comprising a charge controller,
• a cooling fan (G), and
• a remote monitoring device,
• wherein said planar wall with said supporting structure (A1) and said photovoltaic module (A) forms a casing,
• said control unit (D), charge controller (E), cooling fan (G) and string (F1) being housed in said casing.
