LED BASED PEDESTAL-TYPE LIGHTING STRUCTURE
First Claim
1. A lamp, comprising:
- a pedestal;
a solid state light source on said pedestal;
a shaped phosphor arranged remote to said solid state light source so that at least some light from said solid state light source passes through said remote phosphor and is converted to a different wavelength of light; and
a diffuser to diffuse light emitting from lamp in an omnidirectional emission pattern.

Abstract
LED based lamps and bulbs are disclosed that comprise a pedestal having a plurality of LEDs, wherein the pedestal at least partially comprises a thermally conductive material. A heat sink structure is included with the pedestal thermally coupled to the heat sink structure. A remote phosphor is arranged in relation to the LEDs so that at least some light from the LEDs passes through the remote phosphor and is converted to a different wavelength of light. Some lamp or bulb embodiments can emit a white light combination of light from the LEDs and the remote phosphor. These can include LEDs emitting blue light with the remote phosphor having a material that absorbs blue light and emits yellow or green light. A diffuser can be included to diffuse the emitting light into the desired pattern, such as omnidirectional.
