    摘要: The present invention relates to a device with electron beam excitation for making a white light source. The device with electron beam excitation comprises: an electron emissive layer for providing an electron beam; and a fluorescent layer comprising a fluorescent powder, wherein the fluorescent powder comprises at least four elements of Zn, S, Se and O. The fluorescent layer can be excited by an electron beam and then emit white light. Accordingly, the present invention can provide a white light source with high color rendering index.

    摘要: A field emission lamp, capable of preventing the degradation and the non-uniformly distribution of the light intensity of the emitted light, even after long-term usage of the field emission lamp, is disclosed. The anode of the disclosed field emission lamp is not required to be transparent. The disclosed field emission lamp comprises: a transparent shell; an anode unit set inside the transparent shell; a cathode unit set between the anode unit and the transparent shell; and a phosphor layer set above the anode unit. The cathode unit is apart from the phosphor layer with a certain distance. The phosphor layer and the anode unit are both surrounded by the cathode unit.
