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 configured to transmit light, the envelope extending along the axis; and
multiple strips inside the envelope, each of the strips extending from a first end to a second end opposite the first end, each of the strips comprising:
a light-transmissive substrate layer of a dielectric material, the substrate layer having a top surface and an opposing bottom surface continuously extending from the first end to the second end;
a plurality of bare light-emitting diode (LED) dies arranged along the top surface of the substrate layer between the first and second ends of the strip, the bare LED dies emitting light with a first efficacy when driven at a first drive current density and emitting light with a second efficacy when driven at a second drive current density, the second drive current density being higher than the first drive current density but the second efficacy being lower than the first efficacy;
conductors arranged to provide electrical power to the bare LED dies; and
an encapsulant encapsulating the bare LED dies;
multiple connectors mechanically attached to the strips, the connectors providing electrical connections to the strips; and
a driver configured to receive electrical power from the base and control electrical power provided to the bare LED dies, the driver being configured to drive the bare LED dies at the first drive current density; wherein each of the strips is individually distinct and spaced apart from the other strips.
