Publication number: 20050129358Abstract: In some embodiments, an apparatus for use generating illumination is provided that comprises a reflective base, a first light source positioned proximate the reflective base, and a reimaging reflector positioned partially about the first light source, where a percentage of light emitted from the first light source is reflected from the reimaging reflector to the reflective base adjacent the first light source establishing a first real image. The reimaging reflector can further comprise a first sector of a first ellipsoid and a second sector of a second ellipsoid, where the first and second sectors establish the first and a second real image. Further embodiments provide a lens that includes a reimaging reflector that receives light and reflects the light establishing a first real image. The reimaging reflector can further comprise a plurality of sectors that reflect light to establish first and second real images.Type: ApplicationFiled: January 21, 2005Publication date: June 16, 2005Applicant: Light Prescriptions Innovators, LLC a Delaware limited liability companyInventors: Juan Minano, Pablo Benitez, Waqidi Falicoff, Yupin Sun, William Parkyn, Roberto Alvarez

Publication number: 20040228131Abstract: An optical device for coupling the luminous output of a light-emitting diode (LED) to a predominantly spherical pattern comprises a transfer section that receives the LED's light within it and an ejector atop it that receives light from the transfer section and spreads it spherically. The base of the transfer section is optically coupled to the LED so that the LED's light goes inside the transfer section, which comprises a compound elliptic concentrator operating via total internal reflection. The ejector section can have a variety of shapes, and can have diffusive features on its surface as well. The device is circularly symmetric, with a height preferably only a few times its diameter. An important application is for use at the focus of the parabolic reflectors in flashlights. This version of the invention further comprises a base-can identical in outer shape and electric contacts to those of flashlight bulbs. Within the can is the current-control circuitry the interfaces the LED with battery voltage.Type: ApplicationFiled: June 12, 2003Publication date: November 18, 2004Applicant: LIGHT PRESCRIPTIONS INNOVATORS, LLC, a Delaware limited liability companyInventors: Juan C.

Publication number: 20040105171Abstract: 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 profiles going beyond 90° are tilted to bring the rim level with the source, the deflected rays exiting the lens to form an off-axis beam.Type: ApplicationFiled: July 18, 2003Publication date: June 3, 2004Applicant: LIGHT PRESCRIPTIONS INNOVATORS, LLC, a Delaware limited liability companyInventors: Juan C.

Publication number: 20040070855Abstract: A method for manufacturing an apparatus and the apparatus being configured to convert a first distribution of an input radiation to a second distribution of output radiation. The method consists of the steps of generating a two-dimensional representation of at least three active optical surfaces of an optical device including calculating a segment of a first surface based on edge ray sets as a first generalized Cartesian oval, calculating a segment of an entry surface based on the edge ray set as a second generalized Cartesian oval, calculating a segment of a second surface based on the edge ray set as a third generalized Cartesian oval, and successively repeating the steps of calculating the segment of the first surface and calculating the segment of the second surface in a direction towards a source, and rotationally sweeping the two-dimensional representation about a central axis providing a three-dimensional representation of the optical device.Type: ApplicationFiled: October 11, 2002Publication date: April 15, 2004Applicant: Light Prescriptions Innovators, LLC, a Delaware limited liability companyInventors: Pablo Benitez, Juan C.
