HIGH LIGHT FLUX COLD-CATHODE FLUORESCENT ILLUMINATE LAMP

摘要

A high light flux, which can reach 800-50000 lm, cold-cathode fluorescent illuminate lamp, comprises at least one cold-cathode fluorescent tube with a 5-16 mm outside diameter and a length being 200-1000 times as much as the outside diameter, an area of the tube electrode which can emit electrons is 100-2000mm2. The ratio of the emitting-current of the electrode to the electron-emitting area of the electrode is 0.01-0.2mA/mm2, the current density of the tube is 0.8-8mA/mm2 and the working frequency is 50Hz-100kHz. The shape of the tube can be several U-shapes, several bridgeable U-shapes, single/double spiral shapes, flat single/double spiral shapes. The tube is bent into at least two sections arranged closed to each other and the spacing of the adjacent tubes is five times smaller than the outside diameter of the tube.
