Pre-rotated overmoulded bidirectional spreading lens for stretched leadframe architecture

A method for manufacturing a solid state light-emitting device (LED) lighting apparatus, comprising:

• forming a leadframe assembly, comprising:
• forming a group of leadframes on a leadframe substrate, the leadframes being spaced apart at a first pitch, each leadframe comprising one or more pads;
• and
• forming interconnects on the leadframe substrate, the interconnects being in an initial folded state, each interconnect linking two adjacent leadframes;
• mounting LEDs on the leadframes;
• disposing optical elements about the LEDs;
• wherein disposing the optical elements comprises orienting the optical elements so the optical elements provide a predetermined light pattern after stretching the leadframe assembly;
• and
• stretching the leadframe assembly so the interconnects unfold to space apart the LEDs at a second pitch greater than the first pitch.
