  • Patent number: 11719412
    Abstract: An LED lighting device, extending along and about a central longitudinal axis, comprises at least one LED light source and a lens made of a transparent material, positioned along the axis; the lens having a concave inlet surface, facing the source, and a convex outlet surface, substantially aligned along the axis and extending about the axis; the inlet surface and the outlet surface have respective elliptic profiles, being defined by respective revolution surfaces generated by the rotation about the axis of respective ellipse portions belonging to a first and a second generatrix ellipses respectively.

  • Patent number: 11549673
    Abstract: A lighting apparatus comprises a plurality of light modules; each module comprises: a hollow body provided with a light box having a light exit opening and housing a LED light source controlled by a control unit; a diffusing screen positioned on the opening to uniform the light passing through the opening; a closure cover, positioned above the diffusing screen; a transparent capacitive film positioned on a face of the closure cover and connected to the control unit to define a touch control device of the module; the modules are shaped as respective polyhedral sectors arranged around the first axis and each module defines an independent light module controlled by the respective touch control device independently of the other modules.
