Abstract

An optoelectronic semiconductor component includes one or more light-emitting diode chips. The light-emitting diode chip has a main radiation side. A diaphragm is arranged downstream of the main radiation side along a main radiation direction of the light-emitting diode chip. The diaphragm is mounted on or in a component housing. The main radiation side has a mean edge length of at least 50 μm. The diaphragm can be switched from light-impervious to light-pervious. The diaphragm comprises precisely one opening region for radiation transmission. The semiconductor component can be used as a flashlight for a mobile image recording device.
