An apparatus is disclosed including a wave-guide containing a luminescent material which responds to incident light by emitting frequency-shifted light. A first portion of the frequency-shifted light is internally reflected within the wave-guide to a wave-guide output, and a second portion of the frequency-shifted light is transmitted out of the wave-guide. The apparatus further includes a diffuse reflector positioned proximal to the waveguide to reflect at least some of the second portion of the frequency-shifted light back in to the waveguide to be internally reflected within the wave-guide to a wave-guide output.
