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: 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: Faceted optics for use in conjunction with (typically planar) arrangements of discrete light sources (e.g., an array of multiple LED dies) improve or optimize the trade-off between beam divergence and beam non-uniformity, and between non-uniformities resulting from the imaging of the extended light source and artifacts introduced by the optic itself.
