Abstract

Disclosed is a field emission device, comprising a central plate, two first plates, two second plates, an electron source and a rotating shaft stacked on each other, the central plate includes a central substrate and two first cathode layers, and the two first The flat plates are respectively arranged symmetrically on one side of the two disk surfaces of the central flat plate, and the two second flat plates are respectively symmetrically arranged on one side of the two disk surfaces of the central flat plate, and each first flat plate is located between the second flat plate and the central flat plate, The first flat panel includes a first fluorescent layer, a first anode layer, a first substrate and a second cathode layer, the second flat panel includes a second fluorescent layer, a second anode layer and a second substrate, and the electron source is located in the center Between the flat plate and the first flat plate, and between the first flat plate and the second flat plate, the rotating shaft is used to drive the two first flat plates to rotate synchronously. The field emission device has various light colors, is easy to switch, has a simple structure, is easy to control, and has high practicability, and can be applied to double-sided light-emitting and colorful decorative lamps.

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 an emerging light source device. Because of its advantages of uniform, thin, and surface light emitting, it has been widely used in decoration, display, lighting equipment and microwave components, and has huge applications. potential. [0003] Existing field emission devices mainly achieve the purpose of decoration by changing their light colors, but the current common field emission devices used in decorative lamps are still relatively monotonous, can only produce a relatively single color, and usually require a complex driving system. Summary 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 diversified light colors and easy conversion of the field emission d...
