Abstract: An optoelectronic component emitting electromagnetic radiation, comprising a housing body which has a cavity, the cavity being fashioned trenchlike and in the cavity a plurality of semiconductor chips being arranged in a linear arrangement. Two neighboring semiconductor chips have a distance from one another which is less than or equal to one-and-a-half lateral edge lengths of the semiconductor chips and greater than or equal to 0 μm. In addition, an illumination module comprising such a component is disclosed.

Abstract: A projection apparatus is specified, comprising a light modulator having a light receiving region with a cross-sectional area to be illuminated of the size AM and a maximum acceptance angle a for incident light, and at least one light source by means of which, during its operation, a light cone is produced for illuminating said cross-sectional area of said light receiving region and which comprises a number N of LED chips having a maximum radiation angle β. At least one of the LED chips has a radiation decoupling area of the size AD. The relation 0.7·(AM·sin2(α))/(AD·sin2(β)·n2)≦N≦1.3·(AM·sin2(α))/(AD·sin2(β)·n2) applies, where n is equal to 1 or to the refractive index of a coupling medium with which the LED chips are provided.
