    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: In one embodiment of the present invention, an electron/photon source is disclosed based on field emission, cathodoluminescent and photo-enhanced field emission, including an evacuated chamber inside a housing, further including an anode and a cathode arranged inside the evacuated chamber. Furthermore, the cathode is arranged to emit electrons when a voltage is applied between the anode and cathode, the anode being arranged to emit light at a first wavelength range when receiving electrons emitted from the cathode, and a wavelength range converting material arranged to receive the emitted light of the first wavelength range and emit light at a second wavelength range. In a novel way, an embodiment of the present invention makes it possible to, in two steps, convert the electrons emitted from the cathode to visible light. The invention has shown to be advantageous, and makes it possible to select new emission materials, manufactured at a fraction of the cost associated with the earlier used materials where the electron to visible light conversion was done in one step.

    Abstract translation: 在本发明的一个实施例中，基于场发射，阴极发光和光增强场发射，包括壳体内的抽真空室，还包括布置在抽空室内的阳极和阴极，公开了一种电子/光子源。 此外，当在阳极和阴极之间施加电压时，阴极被布置为发射电子，阳极被布置成在接收从阴极发射的电子时发射第一波长范围的光，并且布置成接收阴极的波长范围转换材料 发射第一波长范围的光并发射第二波长范围的光。 以新颖的方式，本发明的实施例使得可以在两个步骤中将从阴极发射的电子转换成可见光。 本发明已被证明是有利的，并且使得可以选择新的发射材料，这些新的发射材料以与之前使用的材料相关的成本的一部分制造，其中电子到可见光转换在一个步骤中进行。
