| 发明名称 | 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. | ||

| 主权项 | 1. A projection unit comprising 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, 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, provision is made of a control unit is configured to control the setting unit, which controls the setting unit depending on the light intensity distribution detected by the measuring unit or depending on the period of operation of the lamp. | ||
