Abstract:
A projection lamp for illumination includes a pump radiation unit configured to emit pump radiation, a phosphor element for the at least partial conversion of the pump radiation into a conversion light, and a micromirror array having a multiplicity of micromirror actuators which are arranged in the form of a matrix. The projection lamp is set up such that, during operation, the phosphor element is irradiated by the pump radiation from the pump radiation unit. The conversion light which is thereupon emitted by the phosphor element at least partially makes up an illumination light, which illumination light is guided for adjusting a light distribution over the micromirror actuators. The micromirror actuators are illuminated inhomogeneously with the illumination light at respective times to support the light distribution that is adjusted using the micromirror array.
