Abstract
A light-emitting device (100) is specified, which has a housing (1) with a mounting surface (12) and a housing recess (13), a semiconductor laser diode (2) being arranged in the housing recess, which is intended and embodied to emit laser light (20) in a direction parallel to the mounting surface (12) during operation, an optical element (4) being arranged downstream of the semiconductor laser diode in the beam path of the laser light, the semiconductor laser diode being mounted in the housing in such a way that the laser light has a maximum divergence in a plane parallel to the mounting surface, the optical element having a light-incoupling surface (41), exactly one reflector surface (42) and a light-outcoupling surface (43), the optical element being a one-piece housing cover which completely covers the housing recess in which the semiconductor laser diode is arranged, and the light-outcoupling surface being part of an outer surface of the optical element opposite the mounting surface.
