    摘要： 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.

    摘要： An LED lamp or bulb is disclosed that comprises a light source, a heat sink structure and an optical cavity. The optical cavity comprises a phosphor carrier having a conversions material and arranged over an opening to the cavity. The phosphor carrier comprises a thermally conductive transparent material and is thermally coupled to the heat sink structure. An LED based light source is mounted in the optical cavity remote to the phosphor carrier with light from the light source passing through the phosphor carrier. A diffuser dome is included that is mounted over the optical cavity, with light from the optical cavity passing through the diffuser dome. The properties of the diffuser, such as geometry, scattering properties of the scattering layer, surface roughness or smoothness, and spatial distribution of the scattering layer properties may be used to control various lamp properties such as color uniformity and light intensity distribution as a function of viewing angle.
