Patent number: 8846423Abstract: A device is provided with at least one light emitting device (LED) die mounted on a submount with an optical element subsequently thermally bonded to the LED die. The LED die is electrically coupled to the submount through contact bumps that have a higher temperature melting point than is used to thermally bond the optical element to the LED die. In one implementation, a single optical element is bonded to a plurality of LED dice that are mounted to the submount and the submount and the optical element have approximately the same coefficients of thermal expansion. Alternatively, a number of optical elements may be used. The optical element or LED die may be covered with a coating of wavelength converting material. In one implementation, the device is tested to determine the wavelengths produced and additional layers of the wavelength converting material are added until the desired wavelengths are produced.Type: GrantFiled: July 8, 2013Date of Patent: September 30, 2014Assignee: Philips Lumileds Lighting Company LLCInventors: Michael D.

Patent number: 8231251Abstract: Collection optics are used with one or more light emitting diodes to produce, e.g., collimated light. The collection optics are produced in multiple pieces including a small reflective ring that surrounds the one or more light emitting diodes. The reflective ring may be positioned relative to the LEDs, using a mesa upon which the LEDs are mounted, as a lateral positioning guide. A separate upper reflector uses the reflective ring as a lateral positioning guide during assembly. The reflective ring and the upper reflector include reflective sidewalls that are approximately continuous when the reflective ring and upper reflector are assembled.Type: GrantFiled: October 28, 2005Date of Patent: July 31, 2012Assignee: Philips Lumileds Lighting Company LLCInventors: Gregory W.

Patent number: 7952112Abstract: A submount for red, green, and blue LEDs is described where the submount has thermally isolated trenches and/or holes in the submount so that the high heat generated by the green/blue AlInGaN LEDs is not conducted to the red AlInGaP LEDs. The submount contains conductors to interconnect the LEDs in a variety of configurations. In one embodiment, the AlInGaP LEDs are recessed in the submount so all LEDs have the same light exit plane. The submount may be used for LEDs generating other colors, such as yellow, amber, orange, and cyan.Type: GrantFiled: April 29, 2005Date of Patent: May 31, 2011Assignee: Philips Lumileds Lighting Company LLCInventor: Franklin J.

Patent number: 7754507Abstract: A semiconductor structure formed on a growth substrate and including a light emitting layer disposed between an n-type region and a p-type region is attached to a carrier by a connection that supports the semiconductor structure sufficiently to permit removal of the growth substrate. In some embodiments, the semiconductor structure is a flip chip device. The semiconductor structure may be attached to the carrier by, for example, a metal bond that supports almost the entire lateral extent of the semiconductor structure, or by interconnects such as solder or gold stud bumps. An underfill material which supports the semiconductor structure is introduced in any spaces between the interconnects. The underfill material may be a liquid that is cured to form a rigid structure. The growth substrate may then be removed without causing damage to the semiconductor structure.Type: GrantFiled: June 9, 2005Date of Patent: July 13, 2010Inventors: John E. Epler, Oleg B.

Patent number: 7144135Abstract: An LED lamp includes an exterior shell that has the same form factor as a conventional incandescent light bulb, such as a PAR type bulb. The LED lamp includes an optical reflector that is disposed within the shell and that directs the light emitted from one or more LEDs. The optical reflector and shell define a space that is used to channel air to cool the device. The LED is mounted on a heat sink that is disposed within the shell. A fan moves air over the heat sink and through the spaced defined by the optical reflector and the shell. The shell includes one or more apertures that serve as air inlet or exhaust apertures. One or more apertures defined by the optical reflector and shell at the opening of the shell can also be used as air exhaust or inlet apertures.Type: GrantFiled: November 26, 2003Date of Patent: December 5, 2006Assignee: Philips Lumileds Lighting Company, LLCInventors: Paul S.
