Abstract:
1. A method for making a light emitting diode lighting module, comprising: (a) packaging a plurality of light emitting diode dies that are respectively formed on a plurality of die-mounting parts of a metal lead frame to form a plurality of light emitting diodes, respectively; and (b) cutting off undesirable supporting parts of the lead frame while leaving the light emitting diodes on the remaining part of the lead frame, wherein the remaining part forms a connecting structure that includes first and second rails extending on two opposite sides of the light emitting diodes, a plurality of first leads each connecting one of the light emitting diodes to the first rail, and a plurality of second leads each connecting one of the light emitting diodes to the second rail, and wherein the undesirable supporting parts include a plurality of transverse portions each of which has two ends connected directly and respectively to the first and second rails and each of which is disposed between two adjacent ones of the light emitting diodes, and a plurality of portions each of which connects one of the light emitting diodes to one of the first and second rails.
