Abstract:
A field emission lamp generally includes a bulb having an open end, a lamp head disposed at the open end of the bulb, an anode, and a cathode. The anode includes an anode conductive layer formed on an inner surface of the bulb, a fluorescent layer deposited on the anode conductive layer, and an anode electrode electrically connected with the anode conductive layer and the lamp head. The cathode includes an electron emission element and a cathode electrode electrically connected with the electron emission element and the lamp head. The electron emission element has an electron emission layer. The electron emission layer includes getter powders therein to exhaust unwanted gas in the field emission lamp, thereby ensuring the field emission lamp with a high degree of vacuum during operation thereof. A method for making such field emission lamp is also provided.
