Projector with optical conversion media pumped by low etendue source

A projector system, comprising:

• exactly one imaging array;
• a low-etendue light source having an etendue less than 10 millimeters squared—steradians with a center wavelength less than 470 nanometers;
• a plurality of optical conversion media in a reflective configuration, the optical conversion media having emission wavelengths longer than the wavelength of the low-etendue light source;
• a first optical path which extends from the low-etendue light source to the optical conversion media;
• a second optical path which extends from the optical conversion media to the imaging array;
• and
• a structure for steering light from the low-etendue light source with respect to the plurality of optical conversion media on the first optical path.
