PROJECTION UNIT AND METHOD FOR CONTROLLING THE PROJECTION UNIT

摘要

A projection unit may include a reflector-lamp arrangement which is designed to emit light during operation, wherein the light radiates toward an aperture, wherein a setting unit is provided, with which a light intensity distribution of the emitted light is adjustable relative to the aperture, wherein the light intensity distribution is adjusted depending on a period of operation of the lamp, and/or a measuring unit is provided, with which at least part of the light intensity distribution is detectable, wherein the light intensity distribution is adjusted relative to the aperture depending on a change in the light intensity distribution.
