Abstract:
1. An optoelectronic semiconductor component comprising a housing, a radiation-emitting semiconductor chip and a radiation-detecting semiconductor chip, wherein: a first cavity and a second cavity are formed in the housing, the radiation-emitting semiconductor chip has an active layer that generates radiation and is arranged in the first cavity, which is potted with a first potting compound, the radiation-detecting semiconductor chip has an active layer that detects radiation and is arranged in the second cavity, which is potted with a second potting compound, and absorber particles are embedded in the second potting compound, the absorber particles at least partly absorbing the radiation emitted by the radiation-emitting semiconductor chip, wherein the radiation-detecting semiconductor chip: 1) detects only radiation in a wavelength range that differs from the wavelength range of the emitted radiation of the radiation-emitting semiconductor chip, 2) generates visible radiation having a wavelength of 400 nm to 700 nm during operation, 3) detects IR radiation having a wavelength of 800 nm to 1500 nm, and 4) detects external sunlight and switches off the radiation-emitting semiconductor chip if sunlight is detected and switches on the radiation-emitting semiconductor chip if no sunlight is detected.
