29. A projection unit comprising:
a plurality of light sources, the light sources being configured to output light dependent on the operating mode of the projection unit, wherein one of said light sources is a primary light source configured to output light that is used to project a first image during normal projection unit use and wherein another of said light sources is a secondary light source that is conditioned to output light that is used to project a second different image when the primary light source is either warming up, cooling down or non-operational. - View Dependent Claims (30, 33, 34)
