1. A solid state lamp comprising:
a base configured to electrically connect the solid state lamp to a power source, the base defining an axis;
an envelope extending along the axis; and
a strip or a sheet inside the envelope, the strip or sheet comprising:
a substrate;
a plurality of bare light-emitting diode (LED) dies disposed on a top surface of the substrate;
conductors arranged to provide electrical power to the bare LED dies; and
a wavelength-conversion material optically coupled with the bare LED dies,

wherein the envelope further comprises a reflective portion and an exit portion, the reflective portion surrounding the strip or sheet and configured to reflect light from the strip or sheet toward the exit portion, and
the solid state lamp outputs light from the exit portion with a beam distribution narrower than a hemispherical distribution.
