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.

Abstract: LED lamps or bulbs are disclosed that comprise a light source, a heat sink structure and a remote phosphor carrier having at least one conversion material. The phosphor carrier can be remote to the light sources and mounted to the heat sink. The phosphor carrier can have a three-dimensional shape and comprise a thermally conductive transparent material and a phosphor layer, with an LED based light source mounted to the heat sink such that light passes through the phosphor carrier. The phosphor carrier converts at least some of the LED light, with some embodiments emitting a white light combination of LED and phosphor light. The phosphors in the phosphor carriers can operate at a lower temperature to have greater phosphor conversion efficiency and reduced heat related damage. The lamps or bulbs can also comprise a diffuser over the phosphor carrier to distribute light and conceal the phosphor carrier.
