    Abstract: The present invention generally relates to a field emission light source and specifically to a miniaturized field emission light source that is possible to manufacture in large volumes at low cost using the concept of wafer level manufacturing, i.e. a similar approach as used by IC's and MEMS. The invention also relates to a lighting arrangement comprising at least one field emission light source. The field emission light source comprises: a field emission cathode (106) comprising a plurality of nanostructures (104) formed on a substrate; an electrically conductive anode structure (108) comprising a first wavelength converting material (118) arranged to cover at least a portion of the anode structure, wherein the first wavelength converting material is configured to receive electrons emitted from the field emission cathode and to emit light of a first wavelength range, and means for forming an hermetically sealed and subsequently evacuated cavity (106) between the substrate of the field emission cathode and the anode structure, including a spacer structure (302, 110) arranged to encircle the plurality of nano structures, wherein the substrate for receiving the plurality of nanostructures is a wafer (102′).

    Abstract: The present invention relates to a field emission lighting arrangement, comprising an anode and a cathode, where the shape of the cathode is selected based on the shape of a evacuated envelope in which the anode and cathode is provided. The inventive shape of cathode allows for an improved uniformity of an electric field provided between the anode and cathode during operation of the field emission lighting arrangement. The invention also relates to a corresponding method for selecting a shape of such a cathode.
