Embodiment Construction

[0018] Implementation mode and embodiment:

[0019] 1. Reference image 3 , Figure 4 As shown, the ceramic substrate (2-1) and the nano-cermet emitter (2-3) are prepared, and the preparation process thereof is basically the same as the traditional 95% alumina ceramic production process. The difference is that the rare earth oxide in the nano-cermet emitter (2-3) must be a nano-rare earth oxide.

[0020] 2. Embedding a nanometer cermet emitter (2-3) in the middle and upper part of the prepared ceramic matrix (2-1), and assembling it under the fluorescent lamp filament (2-2).

[0021] 3. According to the tube manufacturing process of fluorescent lamps, the present invention is realized by manufacturing fluorescent tubes.

[0022] The above descriptions are only preferred embodiments of the present invention, and any improvements and modifications made without departing from the principles of the present invention are considered within the protection scope of the present inve...

Abstract

The invention discloses a novel nano ceramic electrode fluorescent lamp tube, which is characterized in that a nano ceramic lamp electrode of the fluorescent lamp tube is composed of a lamp filament supported by a ceramic substrate and a nano metal ceramic emitter. According to the invention, a traditional tungsten lamp electrode is changed into a nano ceramic lamp electrode, the defect that the traditional tungsten lamp electrode is fragile under the condition of high current is overcome, the service life (36000h) of the fluorescent lamp tube is prolonged, the energy consumption loss caused by the fact that the tungsten lamp electrode converts electric energy into heat energy is eliminated, and the lighting effect (119lm / W) of the fluorescent lamp tube is improved.

Description

technical field [0001] The invention relates to the technical field of electric light sources, in particular to a novel nano-ceramic electrode fluorescent tube. Background technique [0002] The main problems of the prior art fluorescent tubes are that the service life of the fluorescent tube is short (6000h) and the luminous efficacy is low (90lm / W). The purpose of the present invention is to manufacture a novel nano-ceramic electrode fluorescent lamp with long service life and high light efficiency aiming at the defects of the prior art. Contents of the invention [0003] In order to achieve the above object, technical scheme of the present invention is: [0004] 1. A novel nano-ceramic electrode fluorescent tube, characterized in that the nano-ceramic lamp electrode (2) of the fluorescent tube (1) is supported by a ceramic substrate (2-1) and a nano-cermet emitting filament (2-2) device (2-3). [0005] 2. According to the novel nano-ceramic electrode fluorescent lamp...
