Optical lighting device and method to produce lighting devices adopting said optical device

摘要

Lighting device and method to make it. The device comprises a light source ( 11 ) including a positive electrode ( 14 ) and a negative electrode ( 13 ) between which a luminescent layer ( 16, 17 ) is located. On the outer side of the multi-layer structure there is a substrate ( 20 ) which diffuses the light generated by the luminescent layer ( 16, 17 ). A lenticular optical element ( 21 ) is associated with a face of the substrate ( 20 ) and is obtained by means of molding in a single piece in the substrate ( 20 ). The optical element ( 21 ) consists of micro-lenses ( 22 ) each one cooperating with a relative point of light emission ( 19 ) to direct and shape the relative ray of light emitted.
