Abstract: An LED lamp has an arrangement of LEDs that results in light emitted in a substantially spherical light field. The LED lamp has a bulb-shaped body with at least one LED at the top and a number of LEDs positioned around the circumference of the body. The LEDs are arranged such that light is emitted forward from the lamp and also from the sides of the lamp. Accordingly, the LED lamp, for example, in operation provides illumination in direction and intensity very similar to an incandescent bulb.

Abstract: A heat dissipation apparatus for a light emitting diode (LED) lamp includes passive heat dissipation elements that enable the LED lamp to meet form factor standards while managing heat to optimize operation and lifespan of the LEDs. The heat dissipation apparatus includes a reflector dish that has surface area enhancement features. The heat dissipation apparatus is in thermal connection with the lamp LEDs. The heat dissipation apparatus further includes a heat pipe that further enhances the passive heat dissipation.

Abstract: A mounting system for a light fixture includes a lamp holder and a mounting device coupled to the holder where the mounting device enables the lamp holder to be mounted in one of a plurality of mounting modes. The mounting modes include a flush mode, a semi-flush mode and attachment to a ceiling fan. The lamps that may be used in the light fixture include a fluorescent lamp, an incandescent, or a halogen lamp. The light fixture with the mounting system that enables multiple mounting modes can be provided as a single product in a single package.

Abstract: A ceiling fan including a lamp ballast in which the drive current frequency is controlled by a voltage-controlled oscillator (VCO) that is capable of precise output frequency control. The VCO frequency is controlled by a microcontroller. The microcontroller may control the VCO frequency in response to various input signals including a triac signal, a manual dimmer control signal, a remote control receiver signal, a light monitor signal, a motion detector signal, or a communication interface signal.
