Embodiment Construction
[0032] The following detailed examples represent preferred embodiments of the application. It should be noted here that the individual features can be realized not only in the stated combination of features, but also in special cases or in other technically reasonable combinations.
[0033] A lighting device, as described below, can be used, for example, in a motor vehicle headlight for a low-beam function, a high-beam function or any desired signal, effect or entertainment light function. Particularly advantageously, such a lighting device can also be used as a projector or the like for home and cinema applications.
[0034] The lighting equipment according to the application of the figure 1 The example shown has a lighting device 1 . Such a lighting device 1 can contain one or more light sources. For example, laser systems, light-emitting diode systems or the like can be used as light sources. figure 1 A control device (not shown) controls or operates one or more light s...

The invention relates to a lighting device, a vehicle headlight and a method for checking the functioning of a lighting device. Lighting equipment should be reliably inspectable. For this purpose, a lighting device is provided with a lighting device comprising one or more light sources and a mirror device comprising a pivotable mirror for directing the light of the one or more light sources. The mirror guides light in a defined first rocking state into a first spatial angle region in which the light is used according to operation, and in a defined second rocking state guides light into a different, In a second spatial angle region in which the light is directed to the absorbing means of the lighting device, and optionally in a third rocking state, the light is directed to a third spatial angle region located between the first and second spatial angle regions , wherein the third rocking state is continuously occupied in the current-free state of the mirror arrangement. Finally, the absorption device has sensors with which the functionality of the lighting device can be checked.
Description
technical field [0001] The invention relates to a lighting device having a light emitting arrangement comprising one or more light sources and a mirror arrangement comprising a rockable mirror or micromirror arrangement for directing the light of the one or more light sources. The mirror can have the following rocking states: a defined first rocking state for directing light into a first spatial angle region in the first spatial angle region; A defined second rocking state in a second spatial angular region different from the spatial angular region in which the light is aimed at the absorbing means of the lighting device and for directing the light to the A third rocking state in a third spatial angular region between the corner regions, wherein the third rocking state is continuously occupied in the current-free state of the mirror arrangement. Furthermore, the invention relates to a method for checking the functioning of such a lighting device. Background technique [00...
