Patent number: 8529102Abstract: A reflector system for a lighting device. The system uses two reflective surfaces to redirect the light before it is emitted. The light source/sources are disposed at the base of a secondary reflector. The first reflective surface is provided by a primary reflector which is arranged proximate to the source/sources. The primary reflector initially redirects, and in some cases diffuses, light from the sources such that the different wavelengths of light are mixed as they are redirected toward the secondary reflector. The secondary reflector functions primarily to shape the light into a desired output beam. The primary and secondary reflectors may be specular or diffuse and may comprise faceted surfaces. The reflector arrangement allows the source to be placed at the base of the secondary reflector where it may be thermally coupled to a housing or another structure to provide an outlet for heat generated by the sources.Type: GrantFiled: April 6, 2009Date of Patent: September 10, 2013Assignee: Cree, Inc.Inventors: Paul Kenneth Pickard, Ryan Kelley

Patent number: 8197096Abstract: A light source device includes a light source unit emitting light of a first wavelength and a wavelength converting element converting light of the first wavelength into light of a second wavelength. An external mirror transmits light of the second wavelength toward an emission destination and reflects light of the first wavelength to resonate between the light source unit and the external mirror. A wavelength separating section transmits light converted from the first wavelength to the second wavelength while traveling from the external mirror to the light source unit and reflects light of the first wavelength in order to separate the different wavelength light. A turnback section reflects light of the second wavelength separated by the wavelength separating section toward the emission destination. In addition, the wavelength separating section reflects light of the first wavelength from the light source unit to travel toward the wavelength converting element.Type: GrantFiled: May 16, 2011Date of Patent: June 12, 2012Assignee: Seiko Epson CorporationInventor: Shunji Kamijima

Patent number: 8192049Abstract: The lighting apparatus includes a first light emitting diode (LED) module, a second LED module and a reflector. The first LED module includes a first plurality of LEDs disposed on one side of a first substrate. The second LED module includes a second plurality of LEDs disposed on one side of a second substrate. The reflector is disposed between the first LED module and the second LED module and may reflect in a light emission direction light emitted from the plurality of the LEDs. Additionally, when the light emitted from the plurality of the LEDs is reflected by a reflective surface of the reflector, and is projected to a plane, images of outermost light sources are distributed on the plane to substantially have a circular shape.Type: GrantFiled: March 4, 2011Date of Patent: June 5, 2012Assignee: LG Innotek Co., Ltd.Inventors: Ji Yeon Hyun, Kyung-il Kong, Seok Jin Kang, Eunhwa Kim

Patent number: 8136967Abstract: An optical lens and method for designing the lens are disclosed. The lens includes a first surface and a second surface. Light emitted from multiple light emitting elements enters the lens through a central section of the first surface. The light can be reflected from a reflective central section of the second surface and/or undergo total internal reflection at an outer ring section of the second surface one or more times before exiting the lens through the outer ring section of the second surface. Upon exiting the lens, the light beam has a predetermined divergence angle and has a fairly uniform color in the far field even if the multiple light emitting elements have different peak wavelengths.Type: GrantFiled: February 25, 2009Date of Patent: March 20, 2012Assignee: Lumenetix, Inc.Inventors: Matthew Weaver, Yuzuru Takashima

Patent number: 8118454Abstract: The present teachings relate to semiconductor-based lighting systems and fixtures which process electromagnetic energy from light emitting diodes or the like. A disclosed exemplary system includes at least one occluded remote phosphor and produces substantially white light of desired characteristics. The remote phosphor extends over at least a portion of a surface of a macro optic at an occluded location such that none of the remote phosphor is directly visible through an optical aperture. The phosphor is responsive to electromagnetic energy from a semiconductor device to emit visible light for the emission through the optical aperture.Type: GrantFiled: December 2, 2009Date of Patent: February 21, 2012Assignee: ABL IP Holding LLCInventors: Jack C. Rains, Jr., David P. Ramer
