Problems solved by technology
However, with the current preparation technology, under the action of a strong electric field, there are still problems such as micro-tip destruction, current fluctuation, performance degradation, poor uniformity of the cold cathode as the emitter, low production efficiency, and high equipment investment.
[0004] In addition, the light color form of the existing field emission light source modules is fixed and single, and the lamps composed of field emission light source modules are bulky and difficult to store or transport

The invention discloses a field emission folding lamp. The field emission folding lamp comprises a plurality of supports which are arranged in an overlapped mode and field emission light source modules which are fixed onto the supports respectively. The field emission light source modules emit light in a one-sided mode, and every two adjacent supports are movably connected through a guide rail pair. The field emission light source modules comprise first pole plates and second pole plates and further comprise isolator frames and gas electron sources, wherein the first pole plates and the second pole plates are arranged in a stacked mode and are externally connected with alternating currents. According to the field emission folding lamp, the gas electron sources replace cold cathode electron emitters, and the technology difficulty and the manufacturing cost are effectively reduced. When the field emission folding lamp is turned on and the supports are unfolded, the field emission folding lamp is variable in light color, adjustable in color temperature, even in light emitting, soft in light and large in light-emitting area by adjusting current polarity, frequency or/and the duty radio of the external connection alternating currents. When the field emission folding lamp is turned off, the supports are foldable. The field emission folding lamp is simple in structure, flexible in application and easy to store or transport.
Description
technical field [0001] The invention relates to the field of lighting, in particular to a field emission folding lamp. Background technique [0002] The field emission light source module is a field emission light-emitting unit, which can realize uniform, thin, and surface light emission. It has been widely used in displays, lighting equipment and microwave components, and has great application potential. [0003] The electron source used in the existing field emission light source module is a cold cathode, and the requirements for the electron emitter used in the cathode are relatively high. The field emission material used requires excellent electron emission capability, low turn-on voltage, high current density transmission and stable current. However, with the current preparation technology, under the action of a strong electric field, there are still problems such as micro-tip destruction, current fluctuation, performance degradation, poor uniformity of the cold cathod...
