Solid State Lamp Using Light Emitting Strips

A solid state lamp comprising:

• a connector configured to electrically connect the solid state lamp to a power source, the connector defining an axis;
• an envelope configured to transmit light, the envelope extending along the axis;
• and
• a strip inside the envelope, the strip comprising:
• a substrate extending from a first end to a second end opposite the first end, the substrate comprising a top surface having a length extending between the first and second ends of the substrate and a width perpendicular to the length, the substrate further having a thickness perpendicular to the length and the width between the top surface and an opposing bottom surface, the length being greater than the thickness;
• a plurality of spaced-apart light-emitting diode (LED) unpackaged dies disposed on the top surface of the substrate between the first and second ends, each of the LED unpackaged dies has a reflector configured to reflect light from within the corresponding LED unpackaged die;
• conductors arranged to provide electrical power to the LED unpackaged dies;
• and
• an encapsulant encapsulating the LED unpackaged dies on the top surface of the substrate,
• wherein the substrate comprises a side surface between the top surface and the bottom surface that is free of the encapsulant, and wherein the strip is supported and electrically connected at the first end.
