Abstract

The invention relates to a novel wireless fluorescent lamp which works in a bright arc transition zone, comprising a lamp tube, an electrode, a drive, a lamp casing and a lamp cup or lampshade. The electrode consists of tungsten, or molybdenum or iron. More than one layers of anti cathode sputtering films are arranged on the surface of the electrode. Super-pure argon air is filled into the lamp tube with an air-filling pressure ranging from 800 Pa to 6665Pa. The work current of the lamp tube is between 7MA and 60MA. A cold end is arranged in the lamp tube and a titanium mercury zirconium aluminum 16 alloy amalgam or an indium mercury zirconium aluminum 16 alloy amalgam is arranged in the cold end. An insulation layer is arranged between the lamp cup or lampshade and the lamp casing. The cold end extends from the lamp cup or lampshade to the insulation layer. The invention enhances light effect and surface brightness, and has small volume, high flux, enhanced reliability and long service life. The manufacture of the drive is easy, the manufacturing cost is low and the cost performance is high, furthermore, the proposal of the EMC is easy, the cost for restraining electromagnetic interference wires is low and the effect for restraining electromagnetic interference is good.

Description

technical field [0001] The invention relates to the field of electricity, in particular to lighting equipment, in particular to fluorescent lamps, and in particular to a novel filamentless fluorescent lamp. Background technique [0002] In the prior art, the current mainstream technology of fluorescent lamps for general lighting is still hot cathode fluorescent lamps with filament arc discharge, and a small part of them are cold cathode fluorescent lamps with glow discharge for auxiliary lighting. The biggest advantage of arc discharge hot cathode fluorescent lamps is high luminous efficiency, simple and stable driving circuit, low cost, and easy application and popularization; the biggest disadvantage is that the lamp tube has a large diameter, large volume, and poor switching performance. The star standard is turned on for 5 minutes and turned off for 5 minutes, it is difficult to exceed 10,000 times, and the effective life (according to the national standard lumen mainten...
