摘要

The light mixture bar (L) is particularly for a projector and has an entry surface (2), together with first, second and third outlet surfaces (9,10,11), a first integrator bar (1), together with a first uncoupling component (4), a second integrator bar (5), a second uncoupling component (6) and a third integrator (7). All these components, in the sequence as given, connect to the first integrator bar. A first end surface of the first integrator bar forms the entry surface and the first integrator bar conducts multi-colored light inwardly coupled via the entry surface to the first uncoupling component, which from the multi-colored light reflects only the light from a first color to the first outlet surface, transmitting the remaining light into the second integrator bar. This remaining light is then conducted to the second uncoupling component, which reflects only the light of a second color to the second outlet surface. The remaining light is transmitted into the third integrator bar which feeds only the light of a third color to the third outlet surface.
