Patent number: 8246210Abstract: 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.Type: GrantFiled: July 15, 2009Date of Patent: August 21, 2012Assignee: Fraen Corporation S.R.L.Inventors: Marco Angelini, Claudia Bigliati
