Abstract: The present invention is a semiconductor structure for light emitting devices that can emit in the red to ultraviolet portion of the electromagnetic spectrum. The semiconductor structure includes a Group III nitride active layer positioned between a first n-type Group III nitride cladding layer and a second n-type Group III nitride cladding layer, the respective bandgaps of the first and second n-type cladding layers being greater than the bandgap of the active layer. The semiconductor structure further includes a p-type Group III nitride layer, which is positioned in the semiconductor structure such that the second n-type cladding layer is between the p-type layer and the active layer.

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: A lamp includes an optically transmissive enclosure for emitting an emitted light and a base connected to the enclosure. At least one first LED filament and at least one second LED filament are located in the enclosure and are operable to emit light when energized through an electrical path from the base. The first LED filament emits light having a first correlated color temperature (CCT) and the second LED filament emits light having a second CCT that are combined to generate the emitted light. A controller operates to change the CCT of the emitted light when the lamp is dimmed.
