Abstract

See full text

In one embodiment, an LED bulb includes a plurality of metal lead frame strips, including at least a first strip, a second strip, and a third strip. First LED dies have their bottom electrodes electrically and thermally connected to a top surface of the first strip. Second LED dies have their bottom electrodes electrically and thermally connected to a top surface of the second strip. The top electrodes of the first LED dies are wire bonded to the second strip, and the top electrodes of the second LED dies are wire bonded to the third strip to connect the first LED dies and second LED dies in series and parallel. The strips are then bent to cause the LED dies to face different directions to obtain a wide emission pattern in a small space. The strips are then enclosed in a thermally conductive bulb having electrical leads.
