PRE-ROTATED OVERMOULDED BIDIRECTIONAL SPREADING LENS FOR STRETCHED LEADFRAME ARCHITECTURE

摘要

A method for manufacturing a solid state light-emitting device (LED) lighting apparatus includes forming a leadframe assembly with a group of leadframes connected in series by folded interconnects, mounting LEDs on the leadframes, disposing optical elements about the LEDs, and stretching the leadframe assembly so the interconnects unfold to space apart the LEDs. Disposing the optical elements includes orienting the optical elements so the optical elements provide a predetermined light pattern after stretching the leadframe assembly.

1. 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; andforming 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.
