Patent number: 8591062Abstract: A lamp has an optically transmissive enclosure and a base. A tower extends from the base into the enclosure and supports an LED assembly in the enclosure. The LED assembly comprises a plurality of LEDs operable to emit light when energized through an electrical path from the base. The tower and the LED assembly are arranged such that the plurality of LEDs are disposed about the periphery of the tower in a band and face outwardly toward the enclosure to create a source of the light that appears as a glowing filament. The tower forms part of a heat sink that transmits heat from the LED assembly to the ambient environment. The LED assembly has a three-dimensional shape. An electrical interconnect connects a conductor to the heat sink where the conductor is in the electrical path between the LED assembly and the base.Type: GrantFiled: March 1, 2013Date of Patent: November 26, 2013Assignee: Cree, Inc.Inventors: Christopher P.

Publication number: 20120051041Abstract: An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises a light engine unit that is surrounded on its perimeter by a reflective pan. A back reflector defines a reflective interior surface of the light engine. To facilitate thermal dissipation, a heat sink is disposed proximate to the back reflector. A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the heat sink mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the heat sink out to the back reflector.Type: ApplicationFiled: August 31, 2010Publication date: March 1, 2012Inventors: Mark Edmond, Dong Lu, Paul Pickard, Nick Nguyen, Gerald Negley, Gary David Trott

Publication number: 20120029852Abstract: A computer system that installs in the proximity of the vehicle's operator by attaching to the vehicle's wiring harness (e.g., via a power outlet in the vehicle cabin). The device, gathers data relating to the operational state of the vehicle's battery, calculates various health information of the battery from the gathered data, and provides the health and operational state of the battery to the vehicle's operator. To facilitate battery health calculations, the device receives input from a temperature sensor that is remote to the battery, such as a temperature sensor in the device's housing or in the vehicle cabin. The temperature reading can be used to approximate the temperature of the battery. The computer system can also support non-battery related functions, such as navigation, theft deterrence, etc. Algorithms utilizing battery health data over multiple load cycles to determine the health of a battery are also disclosed.Type: ApplicationFiled: October 13, 2011Publication date: February 2, 2012Inventors: Lonnie C.
