| 20080304011 | SAFE EYE DETECTION - An eye detection system for safe detection of the eye positions of a subject estimates the distance from the eye detection system to the subject and reduces the power level of at least one primary light source of the eye detection system if the subject is too close to the eye detection system. If the subject is not too close to the eye detection system, the power level of the at least one primary light source of the eye detection system is increased, provided the power level is below a predetermined maximum power level. Primary light from the at least one primary light source reflected from the subject is sensed by an imager to obtain one or more images, from which the eye positions of the subject are estimated. | 12-11-2008 |
| 20110089463 | Light Source - Light sources are disclosed herein. One embodiment comprises a substrate having a first surface and a second surface located opposite the first surface. At least one first electrically conductive layer is affixed to the first surface of the substrate and partially covering the first surface of the substrate. At least one second electrically conductive layer is affixed to the first surface of the substrate and partially covering the first surface of the substrate. A light emitter is affixed to the first surface of the substrate in an area not covered by either of the at least one first electrically conductive layer or the at least one second electrically conductive layer. The substrate may be thinner in the area where the light emitter is affixed than in the areas where the first and second electrically conductive layers are affixed. A heat sink may be attached to the second surface of the substrate. | 04-21-2011 |

| 20080238335 | Light Source Having a Plurality of White LEDs with Different Output Spectra - A solid state light source having first and second component light sources and an interface circuit and a method for making the same are disclosed. The first and second component light sources emit light having first and second color points on different sides of the black body radiation curve. The first and second component light sources include LEDs that emit light of a first wavelength and a layer of a light converting material that converts a portion of that light to light of a second wavelength. The interface circuit powers the first and second component light sources such that the solid state light source has a color point that is closer to the black body radiation curve than either the first or second color points. A third component light source can be included to expand the range of white color temperatures that can be reached by the light source. | 10-02-2008 |
| 20090162955 | LED DEVICE WITH IMPROVED LIFE PERFORMANCE - A light-emitting diode with an improved service life is provided. The diode is formed from a transparent outer shell that contains a heat-resistant encapsulant at least partially surrounding a light-emitting diode clip. The first encapsulant is compressed between the outer shell and a second encapsulant when it is sealed into the outer shell by the second encapsulant. | 06-25-2009 |
| 20110024785 | Light Emitting Diode Device - An electronic assembly includes a Light Emitting Diode (LED) and a substrate. The LED has a solderable surface other than the contacts. The substrate has an opening. The solderable surface is mounted substantially over the opening. When the opening is filled with solder, the solderable surface is metallically bonded with the solder in the opening. | 02-03-2011 |
| 20110147788 | SEMICONDUCTOR DEVICE WITH A LIGHT EMITTING SEMICONDUCTOR DIE - A semiconductor device includes a light emitting semiconductor die mounted on at least one of first and second electrically conductive bonding pads, which are located on a first major surface of a substrate of the device. The light emitting semiconductor die has an anode and a cathode, which are electrically connected to the first and second electrically conductive bonding pads. The semiconductor device further includes first and second electrically conductive connecting pads, which are located on a second major surface of the substrate. The first and second electrically conductive bonding pads are electrically connected to the first and second electrically conductive connecting pads via first and second electrically conductive edge interconnecting elements. | 06-23-2011 |

| 20080296590 | LED-Based Light Source Having Improved Thermal Dissipation - A light source having a plurality of dies mounted on leads that are partially enclosed in a plastic body is disclosed. Each die is powered by first and second contacts. One contact is connected to the lead on which the die is mounted. Light from the LED exits the die through the top surface. Each lead includes a layer of metal of substantially constant thickness. The layer includes a boundary, a die mounting region within the boundary and a heat transfer region within the boundary. The boundary increases in a dimension perpendicular to a line connecting the die mounting region and the heat transfer region. The leads are arranged such that the die mounting regions are proximate to a first point and oriented such that the lines radiate from the first point. The light source can be manufactured using conventional lead frame techniques. | 12-04-2008 |
