Abstract: A lamp has an at least partially optically transmissive enclosure and a base that retains lamp electronics. LEDs are located in the enclosure and are operable to emit light when energized through an electrical path from the base. The LEDs are thermally isolated from the lamp electronics in the base. A heat sink is disposed between the base and the enclosure. The heat sink includes a heat conducting portion that is thermally coupled to the LEDs and a heat dissipating portion that is exposed to the ambient environment. The heat dissipating portion includes fins that have inner edges and create spaces between adjacent ones of the fins. The inner edges are spaced from one another to define an interior open space where the interior open space communicates with the spaces between the fins.

Abstract: A voltage converter includes a converter circuit and a control circuit coupled to the converter circuit and configured to selectively operate the converter circuit in a boost mode or a floating buck mode in response to a level of an input voltage supplied to the voltage converter circuit. The converter circuit may further include an inductor, a first control switch coupled to the control circuit, and a second control switch coupled to the control circuit. The control circuit may be configured to control a state of the first control switch in the boost mode in response to a level of current in the inductor, and the control circuit may be configured to control a state of the second control switch in the floating buck mode in response to the level of current in the inductor.

Abstract: A solid state lighting fixture with an integrated driver circuit. A housing has a base end and an open end through which light is emitted from the fixture. The reflective interior surface of the fixture and the base define an optical chamber. At least one, and often multiple, light sources are mounted at the fixture base along with the circuitry necessary to drive and/or control the light sources. The drive circuit and the light sources are both located in the optical chamber. A reflective cone fits within the optical chamber such that it covers most of the drive circuit and other components at the base of fixture that might absorb light. The reflective cone is shaped to define a hole that is aligned with the light sources so that light may be emitted through the hole toward the open end of the fixture.

Abstract: A power supply includes a switch configured to control flow of current output from an inductor to an output of the power supply. The switch receives a switching signal from a control circuit. An auxiliary bias is generated to power the control circuit. A bias circuit outputs a bias signal that is used to generate the auxiliary bias. The bias circuit senses a level of the auxiliary bias to control output of the bias signal. Output of the bias signal may be controlled to maintain the level of the auxiliary bias at a target level or within a target range.

Abstract: Some embodiments provide a lighting apparatus including a plurality of lighting circuits coupled in series. Each lighting circuit includes a control circuit configured to selectively provide current to at least one LED and at least one charge storage device coupled to the at least one LED. The control circuit may be configured to cause the at least one charge storage device to be selectively charged from a current source and to be discharged via the at least one LED responsive to a varying input. For example, the control circuit may be configured to limit current through the at least one LED to thereby divert current to the at least one charge storage device.
