Definitions
- the present invention relates to an optoelectronic component according to the preamble of claim 1 and a component module according to the preamble of claim 17.
- Radiation-emitting semiconductor components can be arranged in a matrix in order to achieve a light-intensive overall module.
- Such an arrangement referred to as an LED module, is known from DE 10051159 AI.
- a plurality of optoelectronic semiconductor arrangements or semiconductor chips are mounted on a carrier, which in turn is arranged on a heat sink.
- the heat generated can be dissipated.
- the heat generated should not influence the electrical behavior of the semiconductor component, or should influence it only insignificantly.
- this procedure reduces the efficiency of the overall module because of the absorption of radiation from neighboring semiconductor components.
- the radiation and directional characteristics of the module can be improved, since radiation emitted laterally by the individual semiconductor components is at least partially deflected into the main emission direction.
- a module with a high degree of efficiency and a very good directional characteristic can be composed of individual semiconductor components, which are each located in a single reflector. However, it is difficult here, together with a high packing density of the semiconductor components Obtain reflector in the overall module. The contacts of the semiconductor components prevent flexible interconnection and a high packing density.
- the present invention is therefore based on the object of providing an optoelectronic component and component module which enables a close arrangement of adjacent semiconductor components or optoelectronic semiconductor arrangements.
- the object of the invention is to provide a semiconductor component with a contacting arrangement which enables the thermal line to be separated from the electrical line.
- the invention provides an optoelectronic component with an electromagnetic radiation-emitting and / or receiving semiconductor arrangement which is arranged on a carrier which is thermally conductively connected to a heat sink. Bond wires connect the external electrical connections to the connections of the semiconductor arrangement. The external electrical connections are arranged in an electrically insulated manner on the heat sink at a distance from the carrier.
- This procedure has the advantage that the electrical current flow does not run through the heat sink, which dissipates the heat generated during operation of the semiconductor component.
- the carrier contains a carrier substrate and at least one electrically insulating layer arranged thereon.
- the carrier material itself is electrically insulating. Then the semiconductor arrangement does not have to be insulated separately from the carrier and can be arranged on a conductive substrate without short-circuiting with one another or with the heat sink.
- An electrically conductive layer which is connected to an external electrical connection, can be arranged between the semiconductor arrangement and the electrically insulating layer. This is particularly expedient for a semiconductor arrangement on a conductive substrate, because a connection of the semiconductor arrangement can be made over the electrically conductive layer by means of a bonding wire.
- the external electrical connections contain conductor tracks on a printed circuit board.
- the circuit board contains an insulating substrate with a conductor track and can therefore be applied directly to the heat sink.
- a plurality of printed circuit boards can also be arranged one above the other, which are then also insulated from one another.

- This surface of the filling compound facing the front of the housing serves as a reflector surface for an electromagnetic radiation emitted and / or received by the semiconductor arrangement.
- the cavity is partially filled with the filling compound, and due to the adhesive force between the filling compound and the basic housing, the filling compound automatically forms a concave surface in the cavity, since the filling compound creeps up on the lateral inner surfaces of the cavity of the basic housing.
- the parabolic inner surfaces of the filling compound formed in this way form the reflector for the semiconductor arrangement inserted into the cavity.
- reflector surfaces can also be produced by suitable metering of the filling compound in the cavity, even with very small openings in the cavities.
- the side walls of the housing and the filling compound behave like a single reflector, which further improves the light emission performance.
- the conductor tracks, wiring and the like are encased by the filling compound without impairing its functioning.
