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 α 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 &bgr;. 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(&bgr;)·n2)≦̸N≦̸1.3·(AM·sin2(α))/(AD·sin2(&bgr;)·n2) applies, where n is equal to 1 or to the refractive index of a coupling medium with which the LED chips are provided.

Abstract: An LED array comprising at least two LED chips ( 2 ) contains a temperature sensor ( 3 ), and means are provided for regulating the operating current of the LED chips ( 2 ) as a function of the temperature detected by the temperature sensor ( 3 ). This makes it possible for the LED chips ( 2 ) to be operated for long periods at high operating current, thereby reducing the risk of thermal overload.

Abstract: A housing for an optoelectronic component which includes a carrier with a chip mounting surface is disclosed. An optical element which is produced separately from the carrier is applied to the carrier. The chip mounting surface and the optical element define a parting plane, the parting plane between carrier and optical element being arranged in the plane of the chip mounting surface. Also disclosed is an optoelectronic component having a housing of this type and a method for producing an optoelectronic component of this type.

Abstract: Disclosed is a radiation emitting and/or receiving semiconductor component comprising at least one radiation emitting and/or receiving semiconductor chip ( 1 ), which is disposed in a recess ( 2 ) of a housing base body ( 3 ) and is there encapsulated with an encapsulant ( 4 ) that is readily transparent to electromagnetic radiation emitted and/or received by the semiconductor chip ( 1 ). The recess ( 2 ) comprises a chip well ( 21 ) in which the semiconductor chip ( 1 ) is secured, and a trench ( 22 ) that runs at least partway around the chip well ( 21 ) inside the recess ( 2 ), such that between the chip well ( 21 ) and the trench ( 22 ) the housing base body ( 3 ) comprises a wall ( 23 ) whose apex, viewed from a bottom face of the chip well ( 21 ), lies below the level of the surface of the housing base body ( 3 ) from which the recess ( 2 ) leads into the housing base body ( 3 ), and the encapsulant ( 4 ) extends outward from the chip well ( 21 ) over the wall into the trench ( 22 ). A corresponding housing base body is also disclosed.

Abstract: A light source, such as for a projection system, having a plurality of semiconductor chips and at least two different, electromagnetic-radiation-emitting chip types with different emission spectra, each semiconductor chip having a chip coupling-out area through which radiation is coupled out. Furthermore, the light source has a plurality of primary optical elements, each semiconductor chip being assigned a primary optical element, which in each case has a light input and a light output and reduces the divergence of at least part of the radiation emitted by the semiconductor chip during the operation thereof. The semiconductor chips with the primary optical elements are arranged in at least two groups that are spatially separate from one another, with the result that the groups emit separate light cones during operation of the semiconductor chips. The separate light cones of the groups are superposed by means of a secondary optical arrangement to form a common light cone.
