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.
