Abstract: A projection device for projecting at least one image onto a projection surface is provided. According to the present disclosure, a control device of the projection device is designed, on the basis of an evaluation of at least one measured value of a measuring device of the projection device determined during a drive of a discharge lamp of the projection device with a current waveform to be checked, to check the current waveform in respect of its suitability for minimizing an electrode burn-back of a first electrode and a second electrode, and in the case of a positive check result, to retain the checked current waveform, and in the case of a negative check result, depending on a checked commutation vector characterizing the checked current waveform, to create, by means of a specifiable algorithm, a modified commutation vector that characterizes a modified current waveform.

Abstract: Various embodiments may relate to a circuit arrangement for operating at least one discharge lamp having a commutation device and a control device which is coupled to the commutation device. A first measuring device is used to determine in each case first measurement values, which represent a measure of the magnitude of electrode peaks of the discharge lamp, within a test operating phase in which the first electrode and the second electrode are supplied with energy in an asymmetrical manner. A second measuring device is used to determine a second measurement value which is correlated with the current through the discharge lamp at least during the test operating phase. The control device is designed to actuate the commutation device at least as a function of the determined first measurement values and second measurement values. Various embodiments further relate to a corresponding method for operating at least one discharge lamp.

Abstract: According to the present disclosure, a method for operating a discharge lamp of a projection arrangement is provided. The method includes storing the first commutation scheme in the ballast, such that the first commutation scheme fulfils a specification with respect to a first criterion, wherein the first criterion represents an electrode burnback; storing of the second commutation scheme in the ballast, such that the second commutation scheme fulfils a specification with respect to a second criterion; and operation of the discharge lamp with the alternation of the first and the second commutation schemes; characterized in that, a periodic brightness fluctuation in the discharge lamp is employed as the second criterion.

Abstract: A lighting device is provided with a pump radiation source for emitting pump radiation, a first phosphor element for converting the radiation into a first conversion light, a second phosphor element for generating a second conversion light, and a coupling-out mirror arranged downstream of the first element in a beam path with at least part of the first light. The first light is a broadband conversion light having components in first and second spectral ranges, and the coupling-out mirror is transmissive only in one of the two ranges such that, lights having first and second spectral components in the first and second spectral ranges are separated. The second element is arranged in a beam path with the light having the second component and, in response to this excitation, emits the second light, which can be used jointly with the light having the first component in order to increase the efficiency.

Abstract: Various embodiments provide a projection arrangement. The projection arrangement may include a discharge lamp; and a ballast for the discharge lamp. The ballast is designed to provide, during operation of the projection arrangement, a lamp current in the form of alternating current and having an average frequency and a preset waveform, which has a preset commutation scheme, to the discharge lamp. The preset commutation scheme is preset by a preset time sequence of commutations of the lamp current. The ballast is designed to provide the lamp current in such a way that the preset commutation scheme of the lamp current is deviated from repeatedly with at least one preset intervening time period by at least one DC phase with a preset time duration.
