Abstract: A headlight device is disclosed. In an embodiment a headlight device includes a laser light source configured to emit collimated primary radiation, a conversion element comprising conversion regions configured to at least partly convert the collimated primary radiation into secondary radiation and to form luminous regions during operation, and separating webs which separate the conversion regions from one another, wherein the separating webs are nontransmissive to the collimated primary radiation and secondary radiation and a deflection unit configured to direct the collimated primary radiation onto the conversion element and to guide the collimated primary radiation as a scanning beam over partial regions of the conversion element.
