The invention provides a new solid state lamp emitting a light useful for room illumination and other applications. It comprises a solid state Light Source which transmits light through a Separator to a Disperser that disperses the light in a desired pattern and/or changes its color. In one embodiment, the Light Source is a blue emitting LED operating with current high enough for room illumination, the Separator is a light pipe or fiber optic device, and the Disperser disperses the light radially and converts some of the blue light to yellow to produce a white light mixture. The Separator spaces the Light Source a sufficient distance from the Disperser such that heat from the Light Source will not transfer to the Disperser when the Light Source is carrying elevated currents necessary for room illumination.
