Abstract
A methodof manufacturing a ceramic light transmitting barrier cell for enclosing a luminescent material and such a ceramic light transmitting barrier cell are provided. A part of a pre-formed barrier cell is formedby providing a material mix comprising a binder and inorganic particles in a first mold. On the part is provideda sacrificial layer for defining a cavity. A remainder part of the pre-formed barrier cell is formedby providing the material mix in a second mold which already comprises the part with the sacrificial layer. The sacrificial layer is at least partially removedto obtain the cavity. Optionally, the pre-formed barrier cell is heated(and/or sintered) to obtain the ceramic light transmitting barrier cell. The methodof manufacturing is suitable for producing at large scale relatively cheap and accurately formed ceramic light transmitting barrier cells.
