An LED light bulb device including a bulb body, a flex circuit leg, an LED, conversion circuitry and a cap.

LED-based light bulb device

An LED light bulb device that includes a bulb body, a plurality of flexible circuit strips, and at least one LED. The flexible circuit strips are formed to a shape of, and adhered directly to, an interior face of the bulb body. At least one of the flexible circuit strips defines a plurality of stress-relieving notches. At least one LED is mounted to a corresponding one of the flexible circuit strips and is electrically connected to a conductive trace formed by the flexible circuit strip. The LEDs are arranged to aim inwardly relative to the bulb body. In some embodiments, a rear surface of each of the flexible circuit strips is adhesively attached to the interior face of the bulb body. In some embodiments, a plurality of LEDs are provided and arranged to provide one or both of uniform light distribution and diverse heat distribution.

LED light bulb with internal flexible heatsink and circuit

LED bulb

A pear-shaped light-emitting diode (LED) light bulb housing is provided with a plurality of light-dispersing thickness variations in the bulb envelope. Dimples, bumps, or v-shaped grooves are provided in a middle portion of the bulb envelope in order to uniformly disperse light from LEDs as the light passes through the bulb envelope.

LED bulb optical system with uniform light distribution

LED light bulb

Six internal element LED bulb

Three internal element LED bulb

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.
