Waqidi Falicoff, William A Parkyn, Yupin Sun, Juan Carlos Minano, Pablo Benitez: Circumferentially emitting luminaires and lens-elements formed by transverse-axis profile-sweeps. Light Prescriptions Innovators, Sinsheimer Schiebelhut Baggett, February 3, 2005: US20050024744-A1

The present embodiments provide methods and apparatuses for providing prescribed illumination. Some embodiments provide lenses that include a two-dimensional beam-forming lens-profile where the profile acts to deflect light rays from a light source into a relatively narrow output beam. A zone of hig ...

Juan C Minano, Waqidi Falicoff, Pablo Benitez, William A Parkyn, Julio Pinto Chaves, Yupin Sun: Asymmetric TIR lenses producing off-axis beams. LIGHT PRESCRIPTIONS INNOVATORS a Delaware liability company, Sinsheimer Schiebelhut Baggett, June 3, 2004: US20040105171-A1

The present invention relates to an improvement of a total internal reflection lens whereby a tilted symmetry axis leads to a net deflection of the output beam away from the surface normal of the exit surface. Linear TIR lenses have a net deflection transverse to their focal strip. Circular TIR lens ...

Juan Carlos Minano Dominguez, Pablo Benitez Gimenez: Device for concentrating or collimating radiant energy. Katten Muchin Zavis Rosenman, April 24, 2003: US20030075167-A1

This invention consists in a nonimaging device for concentration or collimation of radiation on a receiver or from an emitter (14), depending on the case. The device is made up of the lens (50), which surrounds the receiver and consists of the aspheric surface (21), and the lens (15), whose upper re ...

Waqidi Falicoff, Julio C Chaves, Pablo Benitez, Juan Carlos Minano, William A Parkyn JR: LED luminance-augmentation via specular retroreflection, including collimators that escape the etendue limit. Light Prescriptions Innovators, Drinker Biddle & Reath, November 27, 2008: US20080291682-A1

The diffuse reflectivity of an LED source is utilized to recycle some of its emission, thereby enabling a luminaire to escape the ├ętendue limit. Retroreflectors intercept the rays destined for the outer part of the luminaire aperture, which can then be truncated. The resulting smaller aperture has t ...
