Light emitting diode (LED) components including multiple LED dies that are attached to lead frames

Abstract:

A Light Emitting Diode (LED) component includes a lead frame and an LED that is electrically connected to the lead frame without wire bonds, using a solder layer. The lead frame includes a metal anode pad, a metal cathode pad and a plastic cup. The LED die includes LED die anode and cathode contacts with a solder layer on them. The metal anode pad, metal cathode pad, plastic cup and/or the solder layer are configured to facilitate the direct die attach of the LED die to the lead frame without wire bonds. Related fabrication methods are also described.
