Abstract

An LED light bulb device including a bulb body, heat sink stems and LEDs. The bulb body defines an exterior and an interior region. The heat sink stems are discrete from one another and extend along the bulb body in a circumferentially spaced fashion. A first LED is directly supported by the first heat sink stem, and a second LED is directly supported by the second heat sink stem. Light from the LEDs is directed inwardly into the interior region and then outwardly from the interior region.
