By texturing the surface, light trapping within the template layer is reduced. Furthermore, by patterning the arrangement of pits, metal coating each pit can be arranged to spread current through the template layer and thus through the n-doped region of a LED.Type: GrantFiled: October 21, 2010Date of Patent: June 25, 2013Assignee: Palo Alto Research Center IncorporatedInventors: David P. Bour, Clifford F. Knollenberg, Christopher L. Chua

Patent number: 8455907Abstract: A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer in order to emit various colored lights including white light. The semiconductor light-emitting device can include a base board, a frame located on the base board, at least one light-emitting chip mounted on the base board, the wavelength converting layer located between an optical plate and each outside surface of the chips so as to extend toward the optical plate using a meniscus control structure, and a reflective material layer disposed at least between the frame and both side surfaces of the wavelength converting layer and the optical plate. The semiconductor light-emitting device can be configured to improve light-emitting efficiency and color variability between the light-emitting chips by using the reflective material layer as each reflector, and therefore can emit a wavelength-converted light having a high light-emitting efficiency from various small light-emitting surfaces.Type: GrantFiled: December 13, 2011Date of Patent: June 4, 2013Assignee: Stanley Electric Co., Ltd.Inventors: Takeshi Waragawa, Kosaburo Ito

Patent number: 8450147Abstract: A process is described for wavelength conversion of LED light using phosphors. LED dies are tested for correlated color temperature (CCT), and binned according to their color emission. The LEDs in each_bin are mounted on a single submount to form an array of LEDs. Various thin sheets of a flexible encapsulant (e.g., silicone) infused with one or more phosphors are preformed, where each sheet has different color conversion properties. An appropriate sheet is placed over an array of LED mounted on a submount, and the LEDs are energized. The resulting light is measured for CCT. If the CCT is acceptable, the phosphor sheet is permanently laminated onto the LEDs and submount. By selecting a different phosphor sheet for each bin of LEDs, the resulting CCT is very uniform across all bins.Type: GrantFiled: March 14, 2012Date of Patent: May 28, 2013Assignee: Philips Lumileds Lighting Company LLCInventor: Haryanto Chandra
