Patent number: 9709242Abstract: A shell integrator has a hollow transparent body with inner and outer surfaces formed as arrays of lenslets. Each lenslet of the inner surface images a common source region in the middle of the hollow body onto a respective lenslet of the outer surface. Each lenslet of the outer surface forms a virtual image of the respective lenslet of the inner surface at the common source region. One integrator has a light-guide following the surface of the hollow body from an inlet end at a central region of the surface to an outlet end at a rim of the hollow body. The light-guide inlet end is shaped to receive light from the common source region and direct such light along the light-guide. Another integrator is generally elongated, and may be semicylindrical. Any of these integrators may have a stepped surface forming a Fresnel lens.Type: GrantFiled: January 5, 2015Date of Patent: July 18, 2017Assignee: Light Prescriptions Innovators, LLCInventors: Pablo Benitez, Julio C.

Publication number: 20170200848Abstract: A high concentration photovoltaic device has a Fresnel lens having a front side and a back side, which may be mounted on a cover plate, and a mirror behind the Fresnel lens and facing the Fresnel lens. A secondary lens is unitary with the Fresnel lens and facing the mirror, and is typically on the inside of the cover plate in the center of the Fresnel lens. A photovoltaic cell in front of the secondary lens faces the mirror through the secondary lens. An additional focusing lens may be provided in front of the mirror. Two optical elements of said device form a Köhler integrator between a remote source, usually the sun, in front of the device and the photovoltaic cell as a target. The mirror may be spectrally selective, with a secondary photovoltaic cell behind the mirror. Additional photovoltaic cells to collect unfocused light may surround the mirror.Type: ApplicationFiled: June 9, 2015Publication date: July 13, 2017Inventors: PABLO BENITEZ, JUAN CARLOS MINANO, RUBEN MOHEDANO, WAQIDI FALICOFF

Patent number: 9123849Abstract: Some photovoltaic cells have a front face accepting incoming incident light and opaque gridlines overlying part of the front face, electrically bonded to the face, with upper reflective facets oblique to the plane of the front face and producing outgoing reflected light. An optical interface parallel to and in front of the front face transmits incoming light to the front face and to the gridlines and reflects back towards the front face by total internal reflection at least some of the outgoing reflected light. Some photovoltaic devices have a triple junction photovoltaic cell, a single junction photovoltaic cell, and a reflective surface arranged to distribute incoming light between the cells. The surface may be a frequency-selective mirror that apportions light so when the cells are in series the power produced, and preferably the photocurrent, is greater than if all the light fell on the triple junction cell alone.Type: GrantFiled: April 23, 2010Date of Patent: September 1, 2015Assignee: Light Prescriptions Innovators, LLCInventors: Pablo Benitez, Juan Carlos Miñano, Rubén Mohedano, Waqidi Falicoff

Patent number: 8393777Abstract: Some embodiments provide luminance-preserving non-imaging backlights that comprise a luminous source emitting light, an input port that receives the light, an injector and a beam-expanding ejector. The injector includes the input port and a larger output port with a profile that expands away from the input port acting via total internal reflection to keep x-y angular width of the source image inversely proportional to its luminance. The injector is defined by a surface of revolution with an axis on the source and a swept profile that is a first portion of an upper half of a CPC tilted by its acceptance angle. The beam-expanding ejector comprising a planar waveguide optically coupled to the output port of the injector. The ejector includes a smooth upper surface, and a reflective lower surface comprising microstructured facets that refract upwardly reflected light into a collimated direction common to the facets.Type: GrantFiled: July 28, 2006Date of Patent: March 12, 2013Assignee: Light Prescriptions Innovators, LLCInventors: Juan Carlos Minano, Pablo Benitez, Julio Cesar Chaves, Waqidi Falicoff, William A.

Patent number: 8355536Abstract: A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a speed estimate from their temperature, as well as determining the trajectory back to the source of fire. In an omnidirectional system a hemispheric imager with an MWIR spectrum splitter forms two CCD images of the environment. Three methods are given to determine the azimuth and range of a projectile, one for clear atmospheric conditions and two for nonhomogeneous atmospheric conditions. The first approach uses the relative intensity of the image of the projectile on the pixels of a CCD camera to determine the azimuthal angle of trajectory with respect to the ground, and its range. The second calculates this angle using a different algorithm. The third uses a least squares optimization over multiple frames based on a triangle representation of the smeared image to yield a real-time trajectory estimate.Type: GrantFiled: February 22, 2010Date of Patent: January 15, 2013Assignee: Light Prescriptions Innovators LLCInventors: Ilya Agurok, Waqidi Falicoff, Roberto Alvarez

Patent number: 8354779Abstract: A heat sink for an LED downlight utilizes tilted fins forming helical air passages that can enhance thermal performance by 30% over conventional fins. To overcome the thermal challenge of installation within the stagnant hot air of insulated ceiling cans, a heat sink has an integral electrostatic air pump on its exterior, to move hot air downwards and drain the stagnant air from the can by establishing a chimney-like circulation up through the heat sink and back down around the outside of the heat sink. The air mover can be powered by a compact high-voltage, low-current power supply similar to those of neon signs. An embodiment of the heat sink is also revealed that is suitable for cooling an LED replacement for standard screw-in or equivalent light bulbs. This device can perform well in variety of orientations (horizontal, vertical, etc.) and fixtures.Type: GrantFiled: January 14, 2010Date of Patent: January 15, 2013Assignee: Light Prescriptions Innovators LLCInventors: Waqidi Falicoff, Yupin Sun, William A.

Patent number: 8322896Abstract: An example of this light bulb has a light emitting element (which may be an LED array) mounted on a circuit board. The circuit board is mounted on one end of a heat-conducting frame. An Edison screw or other suitable connector, for attaching the light bulb electrically and mechanically to a receptacle, is mounted on the other end of the frame. A transparent phosphor-coated ball has a flat chord face optically bonded to said array. A light-permeable globular enclosure is mounted on the frame, surrounding the ball and both homogenizing the white light output of the bulb but also concealing the yellowing unlit appearance of the remote phosphor ball centrally located within it.Type: GrantFiled: October 22, 2010Date of Patent: December 4, 2012Assignee: Light Prescriptions Innovators, LLCInventors: Waqidi Falicoff, Yupin Sun

Patent number: 8280113Abstract: A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a time-varying speed estimate from their time-varying temperature, as well as determining the trajectory back to the source of fire.

Various methods are given to determine the azimuth and range of a projectile, both for clear atmospheric conditions and for nonhomogeneous atmospheric conditions.

Patent number: 8253316Abstract: An LED-powered replacement for the conventional incandescent screw-in light bulb comprises a phosphor coated sphere emitting white light into the same spherical pattern as a frosted incandescent bulb. In one embodiment inside the hollow sphere there is a dielectric cone emitting blue light, which causes the phosphor coating to glow. The blue light comes into the cone from a dielectric totally internally reflecting concentrator (DTIRC), which receives light from a conical reflector surrounding an LED array. The array has blue chips for energizing the phosphor and red chips for supplementing the phosphor light, enabling separate electronic control of the color temperature as well as the overall luminosity of the LED Lamp. Both blue and red chips are controlled by a quantum dimmer.Type: GrantFiled: May 12, 2010Date of Patent: August 28, 2012Assignee: Light Prescriptions Innovators, LLCInventors: Yupin Sun, Waqidi Falicoff, Will Shatford
