  • Method for determining a predefinable wave form of a lamp current for operating a discharge lamp of a projection arrangement, and projection arrangement
    Patent number: 9436072
    Abstract: Various embodiments provide a method for determining a wave form of a lamp current for operating a discharge lamp of a projection arrangement having a color wheel and a ballast, such that a polarity of the electrodes is commutated in accordance with a commutation scheme of the wave form. The method involves providing a wave form having a commutation scheme and checking whether operation of the discharge lamp satisfies one criterion relating to a lifetime of the discharge lamp or a flicker amplitude of the projection arrangement. If the criterion checked is satisfied, checking whether operation of the discharge lamp satisfies the other of the two criteria is carried out. If at least these two criteria are satisfied, the wave form is stored in a memory of the projection arrangement and provided as the predefinable wave form at the ballast for the discharge lamp.

    Patent number: 9405861
    Abstract: This invention relates to a method of designing an illumination device, wherein a light source unit is modeled with a set of rays. Therein, each ray is assigned a light power and is further characterized by a light volume, which specifies how “spread out” the light is in area and angle. In this way, a selection of rays with respect to their “density” becomes possible, and an optical system can be optimized for a transmission of those rays providing the most light per volume.
