An embodiment optoelectronic semiconductor device includes a housing having a leadframe with a first and second connection conductor. The housing further has a housing body surrounding the leadframe in one or more regions. The housing body extends in a vertical direction between a mounting side of the housing body and a front side of the housing body opposite the mounting side. The first connection conductor has a recess. A semiconductor chip configured to generate radiation is arranged within the housing, and the semiconductor chip is disposed in the recess and is affixed to the first connection conductor within the recess. A side face of the recess forms a reflector for reflecting the generated radiation. The first connection conductor protrudes from the housing body at the mounting side. The semiconductor chip is, in at least some regions, free of an encapsulation material adjoining the semiconductor chip.

Optoelectronic light-emitting component and leadframe assemblage

Various embodiments may relate to a semiconductor laser device, including at least one laser diode, and at least one reflection surface which reflects diffusely and which is irradiated by the laser diode during operation, and an additional light-nontransmissive housing body having a cutout. The laser diode is the sole light source of the semiconductor laser device. The laser diode is mounted immovably relative to the at least one reflection surface. Light emitted by the semiconductor laser device during operation has the same spectral components as, or fewer spectral components than, light emitted by the laser diode. An interspace between the laser diode and the at least one reflection surface is free of an optical assembly. A light-emitting area of the semiconductor laser device is greater than a light-emitting area of the laser diode by at least a factor of 100.
