Abstract
A LED lamp includes an optically transmissive enclosure and a base connected to the enclosure. LEDs are mounted on a ribbon for emitting light when energized though an electrical path from the base. The mounting ribbon for the LEDs has a surface that is positioned adjacent an interior surface of the enclosure for transmitting heat from the plurality of LEDs to the enclosure.
Claims18
A LED lamp comprising:
- an enclosure comprising an optically transmissive portion having an interior surface and defining a completely enclosed interior space;
- a base connected to the enclosure;
- a plurality of LEDs mounted on a thermally conductive ribbon for emitting light when energized through an electrical path from the base, wherein the ribbon is in the electrical path to the plurality of LEDs, the plurality of LEDs being disposed near the interior surface of the optically transmissive portion of the enclosure and positioned to direct light primarily inwardly toward a center of the enclosure, wherein the plurality of LEDs are disposed about the periphery of the enclosure, the ribbon having a surface that is disposed adjacent to the interior surface of the optically transmissive portion of the enclosure for transmitting heat from the plurality of LEDs to the enclosure.
A LED lamp comprising:
- an enclosure that is at least partially optically transmissive and comprises an interior surface having a shape;
- a base connected to the enclosure and a tower that extends from the base into the center of the enclosure;
- a plurality of LEDs mounted on a first surface of a thermally conductive ribbon for emitting light when energized through an electrical path from the base, the ribbon having a second surface that is disposed adjacent to the interior surface of the enclosure for transmitting heat from the plurality of LEDs to the enclosure wherein the second surface conforms to the shape of the interior surface over the length of the ribbon and at least one LED mounted on the tower where the at least one LED is spaced internally of the conductive ribbon.
