Abstract

An optoelectronic module (1) having a reflector (4), which comprises an aperture (40) and a structured reflector surface (41), and having at least two connection carriers (3), on each of which there is arranged at least one component (2) provided for producing radiation. The connection carriers are arranged in the interior of the reflector. At least two components of the module exhibit different emission characteristics when the module is in operation, a main emission direction being assigned to each of the two components. The radiation emitted by the components in their respective main emission directions is deflected at least in part in the direction of the aperture by means of the structured reflector surface.
