  • Publication number: 20130277690
    Abstract: A low profile lighting module. Devices according to this disclosure can produce a uniform light intensity output profile, limiting the perceived appearance of individual point sources, from direct lighting modules comprising several light emitting diodes. Individual lighting device components are disclosed that can contribute to this uniform profile, including: primary optics, secondary optics, and contoured housing elements. These components can interact with and control emitted light, thus adjusting its pattern. These components can alter the direction of emitted light, providing a more uniform light intensity over a wider range of viewing angle.

  • Publication number: 20130270577
    Abstract: A trench metal oxide semiconductor field effect transistor or UMOSFET, includes a buried region that extends beneath the trench and beyond a corner of the trench. The buried region is tied to a source potential of the UMOSFET, and splits the potential realized across the structure. This effectively shields the electric field from the corners of the trench to reduce gate oxide stress, and resultantly improves device performance and reliability.

  • Publication number: 20130214666
    Abstract: Lamps and bulbs are disclosed generally comprising different combinations and arrangements of a light source, a reflective optical element, and a separate diffusing layer. This arrangement allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omni-directional emission pattern, even with a light source comprised of an arrangement of LEDs. The lamps according to the present invention can also comprise thermal management features that provide for efficient dissipation of heat from the LEDs, which in turn allows the LEDs to operate at lower temperatures. The lamps can also comprise optical elements to help change the emission pattern from the generally directional pattern of the LEDs to a more omni-directional pattern.
