Abstract: A method 100 of 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 formed 102 by providing a material mix comprising a binder and inorganic particles in a first mold. On the part is provided 104 a sacrificial layer for defining a cavity. A remainder part of the pre-formed barrier cell is formed 106 by providing the material mix in a second mold which already comprises the part with the sacrificial layer. The sacrificial layer is at least partially removed 112 to obtain the cavity. Optionally, the pre-formed barrier cell is heated 114, 116 (and/or sintered) to obtain the ceramic light transmitting barrier cell. The method 100 of manufacturing is suitable for producing at large scale relatively cheap and accurately formed ceramic light transmitting barrier cells.
