Opening claim text (preview).
The invention claimed is: 1. An optoelectronic component comprising: a carrier with at least two radiation sources that generate electromagnetic radiation, a housing consisting of a material non-transmissive to the electromagnetic radiation from the radiation sources, a portion of the housing being a cover with at least two openings having a depression with a housing wall, wherein each opening is closed with a plate, the plate consists of a material transmissive to the electromagnetic radiation from the respective radiation source, a radiation source is respectively assigned to an opening, the cover has a bearing face provided on a lower surface of the cover surrounding the opening, the plate is arranged at least partly in the depression, the plate bears on the bearing face and is fixed on the bearing face, the bearing face is arranged offset relative to an underside of the cover, a distance between the underside of the cover and the bearing face is greater than or equal to the thickness of the plate, an edge region of the housing having a connection face delimits the cover, the connection face connects to an edge of the carrier, the connection face is above the underside of the cover, the housing has two bends arranged between the edge region and the underside of the cover, and the underside of the cover is located between the at least two radiation sources. 2. The component as claimed in claim 1 , wherein the housing has a cover and an edge region, the edge region circumferentially connects to the cover, and the edge region connects to the carrier. 3. The component as claimed in claim 1 , wherein at least one radiation source is a laser diode. 4. The component as claimed in claim 1 , wherein at least one opening is assigned a first device that influences a direction of propagation of the electromagnetic radiation, and the device is a lens. 5. The component as claimed in claim 1 , wherein at least one opening is assigned a second device that alters a wavelength of an electromagnetic radiation, and the second device is a phosphor layer. 6. The component as claimed in claim 1 , wherein the plates hermetically impermeably connect to the housing. 7. The component as claimed in claim 1 , wherein the housing connects to the carrier by a circumferential welded connection. 8. The component as claimed in claim 1 , wherein the radiation source are embodied in the form of at least two laser bars each having a plurality of laser diodes, and each laser bar is separately drivable via electrical terminals. 9. The component as claimed in claim 1 , wherein the cover with the depressions is formed as one part. 10. The component as claimed in claim 1 , wherein a portion of the cover is sleeve-shaped and connects to a ring-shaped bearing face, the plate connects to the cover by a circumferential connecting layer or a solder layer, and the plate is formed from glass, wherein the cover consists of a metallic material, and the depressions are deep drawn. 11. The component as claimed in claim 4 , wherein two openings are assigned two different first devices that differently influence a direction of propagation of the electromagnetic radiation. 12. The component as claimed in claim 5 , wherein two openings are assigned two different second devices, and the two devices change the wavelength of an electromagnetic radiation differently. 13. An optoelectronic component comprising a carrier with at least two radiation sources that generate electromagnetic radiation, comprising a housing consisting of a material non-transmissive to the electromagnetic radiation from the radiation sources, wherein at least two openings are provided in the housing, each opening is closed with a plate provided on a lower surface of the cover, the plate consists of a material transmissive to the electromagnetic radiation from the respective radiation source, and a radiation source is respectively assigned to an opening, an edge region of the housing having a connection face delimits the cover, the connection face connects to an edge of the carrier, the connection face is above the underside of the cover, the housing has two bends arranged between the edge region and the underside of the cover, and the underside of the cover is located between the at least two radiation sources. 14. The component as claimed in claim 13 , wherein the plate connects to the housing by a circumferential connecting layer or a solder layer, and wherein the plate is formed from glass. 15. The component as claimed in claim 13 , wherein the housing has a cover and an edge region, the edge region circumferentially connects to the cover, and the edge region connects to the carrier. 16. The component as claimed in claim 13 , wherein at least one opening is assigned a second device that alters a wavelength of an electromagnetic radiation, and the second device is a phosphor layer. 17. The component as claimed in claim 13 , wherein the plates hermetically impermeably connect to the housing. 18. The component as claimed in claim 13 , wherein the housing consists of a metallic material, and the depressions are produced by deep-drawing. 19. The component as claimed in claim 13 , wherein the housing connects to the carrier by a circumferential welded connection.
