An optical system is disclosed, which comprises a glass light pipe having an input surface for receiving light from a light source and an output surface through which light exits the light pipe, and a polymeric light pipe optically coupled at its input surface to the output surface of the glass light pipe to receive at least a portion of the light exiting the glass light pipe, said polymeric light pipe having a textured output surface. A plurality of microlenses is optically coupled to said textured surface of the polymeric light pipe, and a projection lens is optically coupled to the output surface of the polymeric light pipe to receive light therefrom.

An adjustable light beam lighting device, particularly for a flashlight, has in succession along an axis a light source, a collimator collimating the light into a collimated beam, and a first optical element and a second optical element provided with respective arrays of side-by-side lenses arranged according to a network pattern. The lenses of the first element face respective lenses of the second element and are shaped to, respectively, converge and diverge the light from the collimated beam. A mask between the elements is shaped to laterally screen the light exiting from each lens of the first element and to convey the light exiting from each lens of the first element only on the facing lens of the second element, thus screening the adjacent lenses. A movement mechanism translates the elements with along the axis to vary the width of the beam emitted by the device.

A LED lighting device has a number of LED's, and a multiple optical assembly defined by a number of modular units; each modular unit has a total-internal-reflection lens associated with a LED, and the modular units are connected to one another so as the lenses have respective distinct optical reflecting surfaces.

A lighting device includes a thin transparent plate in which a plurality of micro-lenses arranged in a matrix are integrated. A second thin transparent plate is supported so as to be movable relative to the first plate by means of at least one pair of flexures. A plurality of micro-lenses arranged in a matrix are also integrated in the second plate.
