A mirror system for a projection apparatus, wherein the projection apparatus comprises a light source and an aperture, wherein the mirror system comprises: a support surface; and a plurality of mirrors arranged on the support surface; wherein each of the plurality of mirrors is arranged tiltable between a first and a second tilting position, wherein the first and the second tilting position are discrete positions; wherein each mirror in the first tilting position is arranged to reflect a light beam that is emitted from the light source onto the aperture; wherein each mirror in the second tilting position is arranged to reflect the light beam that is emitted from the light source away from the aperture; wherein a tilting axis of each of the plurality of mirrors passes through or lies below the center of gravity of the mirror; and wherein the first and the second tilting position of each of the plurality of mirrors are asymmetrical to each other; wherein two stopper structures (17-1, 17-2) are arranged on the support surface below each mirror of the plurality of mirrors, wherein a mirror in the first tilting position is in physical contact with one of the two stopper structures (17-1, 17-2), and wherein the mirror in the second tilting position is in physical contact with the other one of the two stopper structures (17-1, 17-2), wherein the two stopper structures (17-1, 17-2) below each mirror of the plurality of mirrors have a different height and/or are arranged at a different distance from the tilting axis of the mirror; and characterized in that at least one recess is arranged in the support surface below each of the plurality of mirrors, wherein an edge of each mirror of the plurality of mirrors in the first and/or the second tilting position at least partially sinks into the recess below the mirror. a support surface; and a plurality of mirrors arranged on the support surface; wherein each of the plurality of mirrors is arranged tiltable between a first and a second tilting position, wherein the first and the second tilting position are discrete positions; wherein each mirror in the first tilting position is arranged to reflect a light beam that is emitted from the light source onto the aperture; wherein each mirror in the second tilting position is arranged to reflect the light beam that is emitted from the light source away from the aperture; wherein a tilting axis of each of the plurality of mirrors passes through or lies below the center of gravity of the mirror; and wherein the first and the second tilting position of each of the plurality of mirrors are asymmetrical to each other; wherein two stopper structures (17-1, 17-2) are arranged on the support surface below each mirror of the plurality of mirrors, wherein a mirror in the first tilting position is in physical contact with one of the two stopper structures (17-1, 17-2), and wherein the mirror in the second tilting position is in physical contact with the other one of the two stopper structures (17-1, 17-2), wherein the two stopper structures (17-1, 17-2) below each mirror of the plurality of mirrors have a different height and/or are arranged at a different distance from the tilting axis of the mirror; and characterized in that at least one recess is arranged in the support surface below each of the plurality of mirrors, wherein an edge of each mirror of the plurality of mirrors in the first and/or the second tilting position at least partially sinks into the recess below the mirror.
