Claim of US Patent No. 10,249,807

1. A solid state light-emitting device (LED) lighting apparatus, comprising:a stretched leadframe assembly, comprising:
leadframes spaced apart at a pitch, each leadframe comprising at least one pad;
interconnects each linking two adjacent leadframes;
LEDs mounted on the leadframes; and
bidirectional spreading lenses disposed 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,
the spreading axis being aligned along the length of the stretched leadframe assembly.
