A light-emitting module is specified, comprising at least two light sources disposed on a common carrier. At least one of said light sources includes at least two LED chips. Each light source of the module is followed downstream by an optic body of an optical element, and the optic bodies are suitable for guiding electromagnetic radiation to a light exit surface of the optical element. An optical projection apparatus comprising such a light-emitting module is also specified.
