1. A method for manufacturing a solid state light-emitting device (LED) lighting apparatus, comprising:forming a leadframe assembly comprising:
leadframes spaced apart at a first pitch, each leadframe comprising one or more pads; and
interconnects in an initial folded state, each interconnect linking two adjacent leadframes;
mounting LEDs on the leadframes;
disposing bidirectional spreading lenses about the LEDs, each bidirectional spreading lens having a spreading axis and a null axis perpendicular to the spreading axis, each bidirectional spreading lens directing more light in opposite directions along the spreading axis than the null axis; and
stretching the leadframe assembly so the interconnects unfold to space apart the LEDs at a second pitch greater than the first pitch;
the spreading axis being aligned with a stretch axis along the length of the stretched leadframe assembly after the leadframe assembly is stretched.
