Abstract
Embodiments of the invention include an ultraviolet (UV) source, the UV source including a semiconductor device comprising an active layer disposed between an n-type region and a p-type region. The active layer emits radiation having a peak wavelength in a UV range. A reflector cup is disposed around the UV source. A transparent cover is disposed over the reflector cup.
