Led light engine for ac operation and methods of fabricating same

摘要: A light engine comprises a pair of LED active elements mounted on common header having first and second terminals. The terminal is connected to the cathode element anode element, while thereby connecting LEDs in an anti-parallel arrangement. single insulating or semi-insulating substrate formed thereon plural with associated p- n-type contacts forming contacts, respectively, for each also provided. may be flip-chip configuration plurality leads. include leads adapted such that two flip-mounted contacting one lead, contact other lead. In addition, permit multiple thereon.
