Patent number: 9574743Abstract: Embodiments of the present invention provide separate optical devices operable to couple to a separate LED, the separate optical device comprising an entrance surface to receive light from a separate LED when the separate optical device is coupled to the separate LED, an exit surface opposite from and a distance from the entrance surface and a set of sidewalls. The exit surface can have at least a minimum area necessary to conserve brightness for a desired half-angle of light projected from the separate optical device. Furthermore, each sidewall is positioned and shaped so that rays having a straight transmission path from the entrance surface to that sidewall reflect to the exit surface with an angle of incidence at the exit surface at less than or equal to a critical angle at the exit surface.Type: GrantFiled: October 22, 2014Date of Patent: February 21, 2017Assignee: Illumitex, Inc.Inventors: Dung T.

Patent number: 9086211Abstract: Embodiments described herein provide optical systems that can mix colors to produce illumination patterns having a large area with uniform color. One embodiment of an optical system can include a set of optical units that each produces an illumination pattern with uniform color and intensity. The optical units are spaced so that the individual illumination patterns overlap to create an overall illumination pattern with an overlap area. In the overlap area, the colors emitted by the individual optical units mix to create a desired color. Embodiments of optical systems can provide beam control so that the optical units emit a high percentage of light in beam.Type: GrantFiled: October 18, 2013Date of Patent: July 21, 2015Assignee: Illumitex, Inc.Inventors: Dung T.

Patent number: 8449128Abstract: Embodiments disclosed herein provide optical systems utilizing photon conversion materials in conjunction with a light source and an LED. An LED can be positioned in a cavity defined by a base and one or more sidewalls. Phosphors can be disposed on the entrance face of a lens between the entrance face to the lens body and the LED so that light emitted from the LED will be incident on the phosphor and down converted before entering the lens body through the entrance face. The lens can positioned so that the phosphors are separated from the LED by a gap.Type: GrantFiled: December 23, 2009Date of Patent: May 28, 2013Assignee: Illumitex, Inc.Inventors: Hyunchul Ko, Randall E.

Patent number: 8263993Abstract: Embodiments of an LED disclosed has an emitter layer shaped to a controlled depth or height relative to a substrate of the LED to maximize the light output of the LED and to achieve a desired intensity distribution. In some embodiments, the exit face of the LED may be selected to conserve radiance. In some embodiments, shaping the entire LED, including the substrate and sidewalls, or shaping the substrate alone can extract 100% or approximately 100% of the light generated at the emitter layers from the emitter layers. In some embodiments, the total efficiency is at least 90% or above. In some embodiments, the emitter layer can be shaped by etching, mechanical shaping, or a combination of various shaping methods. In some embodiments, only a portion of the emitter layer is shaped to form the tiny emitters. The unshaped portion forms a continuous electrical connection for the LED.Type: GrantFiled: June 7, 2010Date of Patent: September 11, 2012Assignee: Illumitex, Inc.Inventors: Dung T. Duong, Paul N.

Patent number: 8115217Abstract: Embodiments disclosed herein provide packaged LED devices in which the majority of the emitted light comes out the top of each LED chip with very little side emissions. Because light only comes out from the top, phosphor deposition and color temperature control can be significantly simplified. A package LED may include a housing positioned on a supporting submount, sized and dimensioned to accommodate a single LED chip or an array of LED chips. The LED chip(s) may be attached to the submount utilizing the Gold-to-Gold Interconnect (GGI) process or solder-based approaches. In some embodiments, phosphor may be deposited on top of the LED chip(s) or sandwiched between glass plates on top of the LED chip(s). The phosphor layer may be inside or on top of the housing and be secured to the housing utilizing an adhesive. The housing may be adhered to the submount utilizing a thermal epoxy.Type: GrantFiled: December 11, 2009Date of Patent: February 14, 2012Assignee: Illumitex, Inc.Inventors: Dung T. Duong, Paul N.

Patent number: 8087960Abstract: Embodiments provide an LED comprising a quantum well region operable to generate light and a substrate having an interface with the quantum well region, wherein light generated by the quantum well region traverses the interface to enter the substrate and exit the LED through an exit face of the substrate. The exit face may be opposite from and a distance from the interface, with some portion or all of this LED being shaped to optimize the light extraction efficiency of the device. The exit face can have at least 70% of a minimum area necessary to conserve brightness for a desired half-angle of light. Sidewalls of the LED may be positioned and shaped so that rays incident on a sidewall reflect to the exit face with an angle of incidence at the exit face at less than or equal to a critical angle at the exit face.Type: GrantFiled: October 1, 2007Date of Patent: January 3, 2012Assignee: Illumitex, Inc.Inventors: Dung T.
