Abstract: In various embodiments, LED-based illumination devices include an inlet region for receiving the LED light that is complementary in shape to the lens of the LED.

Abstract: A control system is disclosed for determining an actual temperature of a light emitting diode. The control system uses conductor that supply power to the light emitting diode to supply a pulse to the light emitting diode. The pulse is determined along with a reaction caused by the pulse and the information gained is used in determination of the light emitting diode die temperature which can then be used in controlling current to the light emitting diode to control the temperature of the light emitting diode.

Abstract: In various embodiments, an illumination device includes a housing, a power connector for connecting the illumination device to a power socket and receiving input power, a light emitter for direct illumination disposed within the housing, a circuit for regulating the input power and providing the regulated power to the light emitter, and a decorative illumination element for providing decorative illumination.

Abstract: Disclosed is a method and apparatus for providing a light emitting diode and driving circuitry integrated into a component module that will retrofit common incandescent lightbulb applications. The disclosed embodiments will perform with high efficiency at a wide operating voltage range with a very small size allowing for the incorporation within the envelope and form of existing lightbulb bases. Therefore, a single universal LED light bulb module can be used to replace the dozens of conventional LED and incandescent lights currently being used. The electronic circuitries used to drive the LEDs are extremely compact and consequently can be incorporated in nearly any standard bulb base.

Abstract: Control systems and methods that directly measure the actual junction temperature of LEDs utilize internal electrical measurements, thereby dispensing with external sensors and/or wires. In various embodiments, the actual junction LED temperature is obtained based on the measured electrical properties, such as the voltage across and/or current passing through the LEDs, during operation. The measured junction temperature may be used in a closed-loop feedback configuration to control the power applied to the LED in order to avoid overheating.

Abstract: A lighting device is disclosed which provides for an adjustable beam. The adjustable beam involves the use of a hologram diffuser with areas that have different diffusing properties. The different diffusing areas are selectively positionable in a light beam created by the lighting device to provide for an adjustable beam by providing different diffusions of the light.

Abstract: The invention is a replacement for a conventional incandescent or halogen light bulb. Besides providing regular illumination, it has advantages over a conventional bulb while maintaining the bulb's decorative function, such as visual effects associated with the bulb's envelope or shade. The invention comprises a connector equivalent to a standard light bulb base, at least one light emitting diode (LED), and a driving circuit hosted on a module such as a printed circuit board and adapting the supply voltage to the requirements of the LED. Compensation for the effects of temperature may be included. The invention may also include other circuitry to support various enhanced features such as novel decorative features or control over the brightness, color, or other characteristics—all potentially varying over time or being controlled remotely.
