Abstract
The invention discloses a field emission lamp, which comprises a field emission luminescence panel and a panel bracket, wherein the field emission luminescence panel is fixedly arranged on the panel bracket. The field emission luminescence panel comprises an electric conduction cathode and an electric conduction anode opposite to the electric conduction cathode. An airtight cavity is formed between the electric conduction cathode and the electric conduction anode. A gas electron source fills in the airtight cavity. The electric conduction anode comprises an anode transparent substrate, an anode transparent electric conduction film arranged on the anode transparent substrate, and a fluorescent powder layer coating the anode transparent electric conduction film. When high voltage is applied to the electric conduction cathode and the electric conduction anode, the gas electron source is ionized under the action of a strong electric field and emits electrons to bombard the fluorescent layer with high potential, so that the fluorescent layer gives out light. In the above field emission lamp, the gas electron source is used for replacing traditional electron emitters, such as carbon nano tubes and the like, so that technology difficulties and preparation costs for preparing a field emission light source can be effectively reduced.
