wherein the first trunk branching members comprising a first trunk second branching member connected to the cross member; and
wherein the cup comprises a periphery and the at least two spaced apart portions of the cup comprise two diametrically opposed portions of the cup periphery and a third portion of the cup periphery, the third portion of the cup periphery being connected to the cross member;
a second lead frame assembly spaced apart from the first lead frame assembly, comprising:
parallel elongate members extending from the mounting surface; and
a cross member connected to end portions of the elongate members;
a light-emitting diode mounted in the cup; and
an electrical connector electrically connecting the light-emitting diode to the second lead frame assembly, wherein the electrical connector is connected to the cross member.
2. A light source comprising:
a mounting surface; and
a first lead frame assembly comprising:
a first lead frame assembly first lateral side portion attached to the mounting surface;
a first lead frame assembly second lateral side portion attached to the mounting surface;
a cup configured to receive a light emitting diode at an upper surface thereof, the cup having a first end connected to the first lead frame assembly first lateral side portion and a second end connected to the first lead frame assembly second lateral side portion; and
a cross member having a first end connected to the first lead frame assembly first lateral side portion and having a second end connected to the first lead frame assembly second lateral side portion;
wherein the first lead frame assembly first lateral side portion comprises:
a first trunk member extending upwardly from the mounting surface;
a first branching member connected to the first trunk member and connected to the cup first end; and
a second branching member connected to the trunk member and connected to the cross member first end.
3. The light source of claim 2 wherein the first lead frame assembly second lateral side portion is a mirror image of the first lead frame assembly second lateral side portion.
4. The light source of claim 2 comprising a second lead frame assembly comprising:
a second lead frame assembly first trunk member attached to the mounting surface:
a second lead frame assembly second trunk member attached to the mounting surface; and
a second lead frame assembly cross member having a first end connected to the second lead frame assembly first trunk member and having a second end connected to the second lead frame assembly second trunk member;
wherein the cup has a light emitting diode mounted therein which is electrically connected to the second lead frame assembly.
5. The light source of claim 2 wherein the cup is connected to the cross member at a peripheral portion thereof.
6. A light source comprising:
a mounting surface;
a first lead frame assembly comprising:
