Title: PRE-ROTATED OVERMOLDED BIDIRECTIONAL SPREADING LENS FOR STRETCHED LEADFRAME ARCHITECTURE
Abstract:
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.
