Among other things, DLP is reflective technology. And there are three DLPs in cinema projectors. There's no way to have a straight forward lightpath with a reflective imager. Same with LCOS. Some machines have an additional 90 degree mirror from lamphouse to light engine - I guess, mostly to shorten total machine length.
But that doesn't mean these machines loose that much light. As a matter of fact, due to new designs of mirrors, integrators, 'digital bulbs', prisms, coatings, etc. the light efficiency of series-2 1.2" DLPs is even better than that of traditional 35mm lamp houses. At least for 2D.
