Abstract

The invention provides a ceramic electrode (cathode) for fluorescent lamps, and the electrode which adopts ceramic technology has a conventional electrode as the electrode support, the outside of which is covered by a semiconductive ceramics layer including electron emission material. The surface of the ceramics has a nano metal layer which is formed by the metal steam adsorbing and sintering on the surface of the ceramics in the process of sintering the ceramics. The service life of the fluorescent lamp adopting the electrode of the invention can reach 30 thousand hours which is four to six times longer than the existing fluorescent lamps, and the luminous flux can reach 94.71 m / W, and the lights are all visible lights, and the electricity can be saved by 43 percent to 47 percent compared with the existing fluorescent lamps under the same brightness.

Description

Ceramic fluorescent lamp electrode and preparation method thereof technical field The invention relates to an electrode, in particular to an energy-saving lamp electrode (cathode), and also relates to a preparation method of the electrode. Background technique Fluorescent lamps are now the most important artificial light source and are widely used all over the world, especially in the field of industrial and commercial lighting. Its high efficacy, good light output, persistence of light output, variety of colors and long service life make it an ideal choice in the lighting fields mentioned above. It is estimated that about 80% of the total light emitted by artificial light sources in the world is emitted by fluorescent lamps. It can be said that the quality of fluorescent lamps is closely related to the lives of millions of households. Fluorescent lamps The fluorescent lamps (tubes, hereinafter referred to as fluorescent lamps) used in various lighting fixtures sold and...
