Abstract: An optoelectronic lamp device, including a carrier having a planar mounting face, at least one laser diode that emits laser radiation, wherein the laser diode has a fast axis and a slow axis, the laser diode is arranged on the mounting face such that the fast axis is formed extending parallel to the mounting face, a first collimator is provided for collimating laser radiation polarized in the direction of the fast axis, and a second collimator is provided for collimating laser radiation polarized in the direction of the slow axis, wherein, in the beam path of the laser radiation emitted by the laser diode, the first collimator is arranged proximally and the second collimator is arranged distally relative to the laser diode so that the laser radiation polarized in the direction of the fast axis can be collimated first, and only then can the laser radiation polarized in the direction of the slow axis be collimated.
