    Abstract: A light-emitting diode (LED) bulb comprises a base and a shell connected to the base. A first set of LEDs is disposed within the shell and is configured to emit light at a first color corresponding to a first black-body color temperature. A second set of LEDs is also disposed within the shell and is configured to emit light at a second color corresponding to a second black-body color temperature that is different from the first black-body color temperature. A control circuit is configured to provide a transitional-power state to the first and second sets of LEDs to transition between an initial-power state and a reduced-power state by producing a shifting color output that corresponds to a predetermined light-output curve.

    Abstract: A light-emitting diode (LED) bulb has an LED within a shell. The LED bulb includes a driver circuit for providing current to the LED. The drive circuit has a thermal protection circuit, which includes a first positive thermal coefficient thermistor with a first switching temperature connected in series with a second positive thermal coefficient thermistor with a second switching temperature. The driver circuit includes a switch-mode power supply (SMPS) controller with an input pin and an output pin. The thermistors are connected to the input pin. When either thermistor temperature is above the respective switching temperatures, the thermal protection circuit causes the SMPS controller to produce a signal with a second duty cycle on the output pin. When both thermistor temperatures are below the respective switching temperatures, the thermal protection circuit causes the SMPS controller to produce a signal with a first duty cycle on the output pin.

    Abstract: An LED bulb has a base, a shell connected to the base, and a thermally conductive liquid held within the shell. The LED bulb has a plurality of LEDs mounted on LED mounting surfaces disposed within the shell. The LED mounting surfaces face different radial directions, and the LED mounting surfaces are configured to facilitate a passive convective flow of the thermally conductive liquid within the LED bulb to transfer heat from the LEDs to the shell when the LED bulb is oriented in at least three different orientations. In a first orientation, the shell is disposed vertically above the base. In a second orientation, the shell is disposed on the same horizontal plane as the base. In a third orientation, the shell is disposed vertically below the base.

    Abstract: A circuit for driving multiple light emitting diodes (LEDs) includes at least two sets of LEDs, each set comprised of one or more LEDs in series. The circuit further includes a single inductor connected in series with the two sets of LEDs. At least one set of LEDs is connected to a shunting transistor connected in parallel with the set of LEDs. The duty cycle of the shunting transistor is controlled by a single controller connected to the shunting transistor and the inductor.
