Abstract
LED lighting device (1) comprising a plurality of LED light sources (3) positioned on a support surface (2) and a plurality of optical elements (4) coaxial to the light sources (3) to generate collimated light beams (5), the light sources (3) being individually inclined relative to a predefined plane (6) to form angles, also different, in such a way that collimated light beams (5) intersect defining convergence points.
Claims14
LED lighting device (1) comprising:
- a support surface (2) constituted by a portion (12) of a semi-cylindrical cladding positioned in such a way as to have concavity (14) of the portion (12) that is substantially tangential to a predefined plane (6);
- a plurality of LED light sources (3) positioned on the support surface (2);
- a plurality of optical elements (4) associated with said light sources (3) and coaxial thereto to generate collimated light beams (5) for covering a defined space to be illuminated, said light sources (3) being individually inclined relative to said predefined plane (6) to form angles, also different, in such a way that collimated light beams (5) intersect defining convergence volumes;
- supports (15) for each of the light sources (3), said supports (15) being mounted internally to said portion (12) of the semi-cylindrical cladding in such a way that the convergence volumes are opposite to the predefined plane (6) relative to said portion (12), each support (15) being provided with a base (15a) whereon is mounted the corresponding light source (3), characterised in that all the bases (15a) have the same superficial extension but different inclination relative to the predefined plane (6).
