CLAIMS:

1. A light-emitting device comprising
a light source, which emits light, and
a first material, located to receive at least a portion of said light,
characterized in that
said first material comprises a ceramic material, and a contact layer is arranged on
said light source to connect said light source to said first material.

2. A light-emitting device according to claim 1, wherein said contact layer has a thickness in the range of 2 to 3 microns.

3. A light-emitting device according to claim 1 or 2, wherein said contact layer is made from chalcogenide glass.

4. A light-emitting device according to any of the preceding claims, wherein said first material comprises a material selected from the group consisting of polycrystallin alumina (Al2O3), yttrium- aluminium-garnet (YAG, Y3AIsOi2), yttria (Y2O3), (MgAl2O4), MgAlON, aluminum nitride (AlN), AlON, and titania (TiO2) doped zirconia (ZrO2), or mixtures thereof.

5. A light-emitting device according to any of the preceding claims, wherein said light source is a light-emitting diode (LED).

6. A light-emitting device according to claim 5, wherein said LED comprises an inorganic second material having a refractive index of greater than 1.75.

7. A light-emitting device according to claim 6, wherein said second material is sapphire.

8. A light-emitting device according to any of the preceding claims, further comprising a luminescent material.

9. A light-emitting device according to claim 8, wherein said luminescent material is in the form of particles.

10. A light-emitting device according to claim 9, wherein said particles are uniformly dispersed in said first material.

11. A light-emitting device according to claim 8, wherein said luminescent material is arranged as a layer in said first material, which layer is located to receive at least a portion of said light.

12. A light-emitting device according to any of the claims 8 to 11, wherein said luminescent material is YA-GrCe.

13. A light-emitting device according to any of the preceding claims, further comprising a reflective coating, which coating at least partly encloses said first material.

14. A method for manufacturing a light-emitting device, comprising
- providing a light source, which emits light,
- arranging a contact layer on said light source,
- applying, with a sintering process, a first material, comprising a ceramic material, to receive at least a portion of said light.

15. A method according to claim 14, further comprising
- applying a luminescent material, in the form of uniformly dispersed particles, by co-sintering with said first material.

16. A method according to claim 14, further comprising
- applying a luminescent material as a layer in said first material, which layer is located to receive at least a portion of said light.
