Problems solved by technology

The larger the light-emitting area, the higher the requirements for the preparation technology. At present, the uniformity of light emission of large-area field emission light sources still needs to be improved, and the problem of performance degradation also needs to be solved.
In addition, large-area field emission devices are not easy to carry and transport due to the limitation of solid structural features

Abstract

The invention provides a field emission lamp bar which comprises a plurality of field emission light source modules sequentially sleeved. Each field emission light source module is of a tubular structure and formed by winding sheets. Each sheet comprises an electric conduction anode and an electric conduction cathode which are stacked. Each electric conduction cathode comprises a first substrate, a first electric conduction film arranged on the surface of the first substrate, and a nanometer electron emission body formed on the first electric conduction film. Each electric conduction anode comprises a second substrate, and a second electric conduction film arranged on the surface, close to the corresponding electric conduction cathode, of the second substrate. The surfaces of the second electric conduction films are coated with fluorescent powder layers. The opening ends of every two adjacent field emission light source modules are provided with an upper stopping part and a lower stopping part respectively so that every two adjacent field emission light source modules can mutually slide instead of slipping off. As the field emission light source modules of the field emission lamp bar can be folded, transportation space can be saved, and the storage difficulty can be reduced; moreover, the field emission light source modules can telescope freely in the horizontal direction, and therefore the lamp bar large in light-emitting area can be obtained.

Description

【Technical field】 [0001] The invention relates to a light bar, in particular to a horizontally shrinkable field emission light bar. 【Background technique】 [0002] Field emission light source (Field emission light source) is a new type of light source. Its light-emitting principle is to introduce a high voltage into the vacuum belt between the emitting electrode and the receiving electrode to generate an electric field, so that electron emitters such as metal tips and carbon nanotubes at low potentials emit Electrons are emitted and bombard the luminescent material at high potential to emit visible light. Field emission light sources are energy-saving and environmentally friendly, and have the potential to replace fluorescent tubes. And because of the advantages of simple device structure, high brightness, wide viewing angle, high luminous efficiency, power saving, easy planarization and large-scale, etc., it is gradually widely used in light source systems for decoration, ...
