Abstract

A light-emitting unit, comprising a substrate and a light-emitting device, which is situated on the substrate (2) and is designed to emit a laser beam. A swiveling light-deflecting device is situated on the substrate. A capping device is situated on the substrate and covers the light-emitting device and the light-deflecting device, the capping device having a first cap section and a transparent second cap section. The first cap section is designed to redirect the laser beam emitted by the light-emitting device onto the light-deflecting device. The light-deflecting device is designed to deflect the redirected laser beam in such a way that deflected laser beam is able to exit through second cap section.
