| 20080273340 | Solid State Light Source Having a Variable Number of Dies - A light source having a die carrier, a lead frame, and an insulating body is disclosed. The die carrier includes a die mounting section connected to a heat transfer section. The die mounting section includes a die mounting area having a lead pad opening contained within the die mounting area. The lead frame includes a lead pad. An electrically insulating material fills the voids between the die carrier and the lead frame to maintain the lead frame and die carrier such that a surface of the heat transfer section is exposed on a surface of the body, the lead pad is positioned in the lead pad opening, and the die carrier is electrically isolated from the lead frame. A plurality of dies are attached to the die mounting area and connected to the lead pad. | 11-06-2008 |
| 20100264450 | LIGHT SOURCE - Embodiments of a light source are disclosed herein. An embodiment of the light source comprises a first terminal and a second terminal. The first terminal comprises a first terminal first portion and a first terminal second portion, wherein at least a portion of the first terminal second portion is located on a first plane, the first terminal second portion comprising at least two contacts separated by a space. A second terminal comprises a second terminal first portion and a second terminal second portion. The second terminal first portion is located proximate the first terminal first portion. The second terminal second portion is located substantially on the first plane and in the space. A light emitter is affixed to the first terminal first portion, the light emitter is electrically connected to the first terminal first portion. A connection exists between the light emitter and the second terminal first portion. | 10-21-2010 |
| 20110044062 | LIGHT SOURCE - An embodiment of a light source comprises a first lead and a second lead.

| 20090129085 | OPTICAL DEVICE - An exemplary embodiment of an optical device may include a lead frame with a plurality of leads and a reflector housing formed around the lead frame. The reflector housing includes a first end face and a second end face and a peripheral sidewall extending between the first end face and the second end face. The reflector housing includes a first pocket with a pocket opening in the first end face and a second pocket with a pocket opening in the second end face. At least one LED die is mounted in the first pocket of the reflector housing, and a light transmitting encapsulant is disposed in the first pocket and encapsulating the at least one LED die. | 05-21-2009 |
| 20100320485 | MULTI-CHIP PACKAGED LED LIGHT SOURCE - A light source having a lead frame, a body, and a plurality of dies, each die having an LED thereon is disclosed. The body includes a top surface, a bottom surface and a plurality of side surfaces. The lead frame includes first, second, and third sections, the first section includes a die mounting area having a first protrusion that passes through the body and terminates in a pad on the bottom surface. The second and third sections each include a protrusion that is bent to form first and second leads that run along one of the side surfaces. Each die is bonded to the die mounting area such that a first contact is electrically connected to the die mounting area, and a second contact is connected to one of the second and third sections. The first protrusion of the first section provides improved heat transfer. | 12-23-2010 |
| 20110140133 | LIGHT EMITTING DEVICE HAVING INCREASED LIGHT OUTPUT - The light intensity emitted from a package is increased by adjusting a portion of the package encapsulant so that light impacting the side walls of the adjusted encapsulant portion will encounter total internal reflection (TIR) with the reflected light directed toward the top surface of the package. The adjusted portion of the package is positioned so that air can be used as the second (exterior) medium with the critical TIR angle being such that light emitted from a light source (such as from an LED die) will be directed primarily so as to escape the package from the top surface as opposed to being scattered internal to the package. In one embodiment, a lower portion of the encapsulant is surrounded by a casing to inwardly direct light from the light source that impacts the side of the encapsulant with an angle less than the critical TIR angle. | 06-16-2011 |
