Claim Text:
1. An apparatus for providing radiant energy to a process chamber, the apparatus comprising: a supporting substrate; a first plurality of solid state light sources disposed on a first surface of the supporting substrate; and a second plurality of solid state light sources disposed on the first surface of the supporting substrate, wherein the first and second plurality of solid state light sources are adjacent and aligned, and each solid state light source in the first plurality of solid state light sources is not directly connected to any solid state light source in the second plurality of solid state light sources, and wherein voltage drop between a first solid state light source and a second solid state light source immediately adjacent to the first solid state light source in the first plurality of solid state light sources and voltage drop between a third solid state light source and a fourth solid state light source immediately adjacent to the third solid state light source in the second plurality of solid state light sources are equal, wherein the first solid state light source and the third solid state light source are immediately adjacent to each other, voltage rating of the first solid state light source and voltage rating of the third solid state light source are matched, the second solid state light source and the fourth solid state light source are immediately adjacent to each other, and voltage rating of the second solid state light source and voltage rating of the fourth solid state light source are matched.
