Abstract

The invention discloses a field emission device. The field emission device comprises a center flat plate, two first flat plates, two second flat plates, an electron source and a rotation shaft which are arranged to be mutually stacked. The center flat plate comprises a center substrate and two first anode layers. The two first flat plates are respectively symmetrically arranged at one side of the two disc surfaces of the center flat plate; the two second flat plates are respectively symmetrically arranged at one side of the two disc surfaces of the center flat plate; each first flat plate is disposed between the second flat plates and the center flat plate; the first flat plates comprise first fluorescent layers, first anode layers, first substrates and second cathode layers; the second flat plates comprise second fluorescent layers, second anode layers and second substrates; the electron source is disposed between the center flat plate and the first flat plates and between the first flat plates and the second flat plates; and the rotation shaft is used for driving the two first flat plates to synchronously rotate. The field emission device has the advantages of various light colors, easy conversion, simple structure, convenient control and high practicality, and can be applied to a decoration light fixture with double-face luminescence and rich colors.

Description

technical field [0001] The invention relates to the field of illumination light sources, in particular to a field emission device. Background technique [0002] Field Emission Device (Field Emission Device) is a new light source device. Because of its advantages of uniform, thin and surface light source, it has been widely used in decoration, display, lighting equipment and microwave components. It has huge application potential. [0003] Existing field emission devices mainly achieve the purpose of decoration by changing their light color, but the form of common field emission devices used for decorative lamps is relatively monotonous, can only produce a single color, and usually requires a complex driving system. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a field emission device, which can simply and effectively realize various light colors of the field emission device and is easy to switch. [0005] In ...
