20120268957 | REFLOW SOLDERABLE, SURFACE MOUNT OPTIC MOUNTING - Reflow solderable, surface mount LED optic mounting devices are provided. Embodiments that include turnings (e.g., made on a swiss turning machine) and stampings (e.g., made with a progressive die) are provided. The LED optic mounting devices are suitably positioned by the same pick-and-place machine that is used to mount LED on planar surface with circuitry and solder pads and are attached to the solder pads by soldering. | 10-25-2012 |

20140140069 | LED ILLUMINATION ASSEMBLIES INCLUDING PARTIAL LENSES AND METAL REFLECTORS - An illumination assembly includes a planar or piecewise planar metal reflector positioned very close to an LED subtending a first azimuthal angle range Θ1 that is less than 360° about the LED and a partial lens positioned close to the LED and subtending a second azimuthal angle range (e.g., Θ2=360°−Θ1) less than 360° about the LED. The metal reflector forming one or more images of the LED that are close to the LED, thereby limiting optical source size growth and reflecting light into the partial lens. | 05-22-2014 |

20140078735 | ENGINEERED LIGHT DISTRIBUTION LED LIGHT BULBS - LED light bulbs especially suited for use in table lamps or floor lamps with lamp shades. The LED light bulbs include optics which provide more limited but more uniform illumination of the lamp shade and provide more uniform illumination through the top and bottom apertures of the lamp shade. The light bulbs comprise an electrical coupling base (e.g., Edison screw base) coupled via an insulating coupling piece to a tube. Metal Core Printed Circuit Boards on which LEDs with lenses are mounted are mechanically coupled to the tube. | 03-20-2014 |
