Solid State Lamp Using Light Emitting Strips

A solid state lamp comprising:

• a base configured to electrically connect the solid state lamp to a power source, the base defining an axis;
• and
• a bulb portion extending along the axis and attached to the base, the bulb portion comprising:
• a 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, the substrate comprising side surfaces on opposing sides of the width of the top surface;
• 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 having 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;
• and
• an electrical connector connected to the strip and covering a portion of one of the side surfaces of the substrate, the electrical connector providing an electrical connection to the strip.
