Abstract
Embodiments of a light source include a substrate having a first end and a second end opposite the first end. A plurality of solid state light emitting diodes (LEDs) form an array, with the plurality of LEDs mounted on the substrate in a row between the first end and the second end. The plurality of LEDs further have a first edge LED and a second edge LED having a first encapsulation lens height relative to the substrate. At least one interior LED having a second encapsulation lens height less than the first encapsulation lens height is disposed between the first edge LED and the second edge LED. The spacing between the plurality of LEDs is substantially uniform.
