Abstract

This invention discloses a field emission device, comprising center flat boards which are stacked, two first flat boards and two second flat boards, electronic sources, a first rotation shaft and a second rotation shaft. Each first flat board is positioned between the first flat board and the second center flat board; the center flat board comprises a center basal plate and two first cathode layers; the first flat board comprises a first fluorescent layer, a first anode layer, a first basal plate and a second cathode layer; a second flat board comprises a second fluorescent layer, a second anode layer and a second basal plate; the electronic sources are arranged between the center flat boards and the first flat boards and between the first flat boards and the second flat boards; the first rotation shaft is used for driving two first flat boards to rotate; the second rotation shaft is used for driving the two flat boards to rotate; and the first rotation shaft and the second rotation shaft have different palstances. The light and color of the field emission device are multiple and easy to change, the structure is easy, the control is easy, the practicability is high, and is applicable to novel decorative light fixtures.

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, and has huge applications. 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] ...
