Abstract: An LED package comprising a submount having a top and bottom surface with a plurality of top electrically and thermally conductive elements on its top surface. An LED is included on one of the top elements such that an electrical signal applied to the top elements causes the LED to emit light. The electrically conductive elements also spread heat from the LED across the majority of the submount top surface. A bottom thermally conductive element is included on the bottom surface of said submount and spreads heat from the submount, and a lens is formed directly over the LED. A method for fabricating LED packages comprising providing a submount panel sized to be separated into a plurality of LED package submounts. Top conductive elements are formed on one surface of the submount panel for a plurality of LED packages, and LEDs are attached to the top elements. Lenses are molded over the LEDs and the substrate panel is singulated to separate it into a plurality of LED packages.

Abstract: Retrofit systems and methods are disclosed for lighting installations, and in particular, to retrofit systems and methods used to retrofit troffer-style lighting installations with LED light sources. Retrofit systems can be used with different light fixtures, but those described are particularly adapted for use with troffer-style fixtures. These retrofit systems can provide the same amount of light as traditional light fixtures already do, for example 1600-4000 lumens or more. The retrofit systems can be used with many different light sources but are particularly well-suited for use with solid state light sources or light engines, such as those utilizing LEDs. Some embodiments of the present invention comprise a mechanical mounting system for installing an LED light engine within an existing lighting system housing or pan, such as a troffer pan, without penetrating the ceiling plenum.
