Abstract

A radiation-emitting component (1) comprising a radiation source, a housing body (6), a radiation exit side (16), an underside (17) which is opposite the radiation exit side (16), a side surface (18) which connects the radiation exit side (16) and the underside (17), and at least one first contact region (2a, 3a). The first contact region (2a, 3a) extends along the side surface (18) and is in the form of a partial region of a carrier (23) that runs outside the housing body (6).
