Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the technical scheme of the present invention is described in further detail:

[0015] Such as figure 1 As shown, the coaxial fluorescent tube of the present invention consists of a large-diameter outer lamp tube 1, a small-diameter inner lamp tube 2, the lead-out wires 3 and 6 of the circular electrode, and the lead-out wires 4 and 5 of the disc-shaped electrode. , Glass bottom seal 7, ring electrode 8, wafer electrode 9, and low-pressure formula gas 10.

[0016] The inner wall of the large-diameter outer lamp tube 1 is coated with fluorescent powder.

[0017] Both the inner and outer walls of the small-diameter inner lamp tube 2 are coated with fluorescent powder.

[0018] figure 1 Among them, the lead-out wires 3 and 6 of the circular electrode are the filaments at one end of the fluorescent lamp, and the lead-out wires 4 and 5 of the disc-shaped electrode are the filaments at the other end of the fluor...

Abstract

The invention discloses a coaxial-line fluorescent tube which consists of a large-diameter outer tube and a small-diameter inner tube. An opening of the large-diameter outer tube faces a base and an opening of the small-diameter inner tube faces the bottom of the large-diameter outer tube, which is equivalent to a coaxial line structure. The bottom of the small-diameter inner tube is provided with an electrode of a disc-shaped emission electron and an electrode of a ring-shaped emission electron is available between the large-diameter outer tube and the small-diameter inner tube. The coaxial-line fluorescent tube does not generate electromagnetic waves outwards so as to lead to no interference of electromagnetic field to the environment, and is applicable to fluorescent illumination in a military electronic warfare environment, aviation, marine navigation and precise laboratory which require no electromagnetic interference and fluorescent illumination devices such as high-grade eye-protection illuminating desk lamps and the like.

Description

technical field [0001] The invention relates to a fluorescent lamp, in particular to a coaxial fluorescent lamp specially used in places with low electromagnetic interference. Background technique [0002] The advantage of fluorescent lamps is that the cost per watt is much lower than that of LED lamps. At the same price, the luminous flux of fluorescent lamps is several times that of LED lamps. The disadvantage of fluorescent lamps is that the glass lamp tube is too thin and too long, has poor mechanical properties, is not resistant to vibration and is easily broken, and the straight tube fluorescent lamp tube is an EMC transmitting antenna, which has poor light control. Contents of the invention [0003] The purpose of the present invention is to provide a coaxial fluorescent lamp, which can eliminate the interference source of the low-pressure discharge lamp, has better durability and improves light control. [0004] The present invention achieves the above purpose thr...
