Abstract: 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.

Abstract: Silicon carbide (SiC) materials including SiC wafers and SiC boules and related methods are disclosed that provide large dimension SiC wafers with reduced crystallographic stress. Growth conditions for SiC materials include maintaining a generally convex growth surface of SiC crystals, adjusting differences in front-side to back-side thermal profiles of growing SiC crystals, supplying sufficient source flux to allow commercially viable growth rates for SiC crystals, and reducing the inclusion of contaminants or non-SiC particles in SiC source materials and corresponding SiC crystals. By forming larger dimension SiC crystals that exhibit lower crystallographic stress, overall dislocation densities that are associated with missing or additional planes of atoms may be reduced, thereby improving crystal quality and usable SiC crystal growth heights.

Abstract: A lighting device comprises a body of optically transmissive material exhibiting a total internal reflection characteristic, the body further comprising a light input surface for receiving light, a light extraction portion spaced from the light input surface, a light transmission portion disposed between the light input surface and the light extraction portion, and at least one light deflection surface for deflecting light toward the light extraction portion. Further in accordance with this aspect the light extraction portion comprises a first extraction surface for extracting light deflected by the at least one light deflection surface out of the body and a second extraction surface for extracting light other than light deflected by the at least one light deflection surface out of the body.

Abstract: A lamp comprises an interior space and a base. An enclosure may be connected to the base to enclose the interior space. At least one LED board divides the interior space into a plurality of sectors. An LED is located in each sector in the enclosure operable to emit light when energized through an electrical path from the base. Light from the LED is reflected by a wall of the sector to create a reflected light source.
