ABSTRACT:
A multi-lamp arrangement for optical systems includes plural lamps and a collective light guide, where each lamp is positioned such as to transmit light into respective light guides that are both optically connected to the collective light guide. In one embodiment, one of the lamps is optically connected to the collective light guide by a mirror and-prism arrangement and an intermediate light guide and an intermediate mirror-and-prism arrangement. An augmented color modulator may be provided with a number of color fields, where the number of identical color fields is equal to the number of lamps.
