Title:
EXTERNAL ELECTRODE FLAT FLUORESCENT LAMP
Document Type and Number:
WIPO Patent Application WO/2014/071609
Kind Code:
A1
Abstract:
An external electrode flat fluorescent lamp, comprising two flat glass plates, at least one glass plate being provided with a discharge tube (1), the two ends of the discharge tube (1) being provided with electrodes (2), the layout of the discharge tube (1) being a distribution around the lamp plate centre of the external electrode flat fluorescent lamp, and the electrodes (2) being located on the outermost periphery of the discharge tube (1).The distribution of the discharge tube (1) is in the form of a disk-type electric furnace.The distribution of the discharge tube (1) is that of two Archimedes spirals with a symmetrical centre connected and communicating at the centre to form the discharge tube (1).The cross-sectional area of the discharge tube (1) close to the centre part of the discharge tube (1) is greater than the cross-sectional area of the discharge tube (1) away from the centre.Provided is an external electrode flat fluorescent lamp with uniform illumination, which is an external electrode fluorescent lamp with a long-service life in which the plate cracking phenomenon does not easily occur.
