Abstract

The invention discloses a test device for simulating fluorescent lamp rectifier effects. The device comprises a base, a diode arranged on the base and two connectors, wherein each of the two connectors is electrically connected onto one polar pin of the fluorescent lamp and the output end of a ballast; the diode is electrically connected between the two connectors; and each connector comprises a snap, an elastic sheet and a pressing line metal block. Unidirectional conductivity of the diode is used to change the use current of the fluorescent lamp, fluorescent lamp current waveform changes, rectifier effects generated when the service life of the fluorescent lamp is ended are simulated, influences on the performance and the service life of the fluorescent lamp ballast can be conveniently detected, and reliability of the fluorescent lamp ballast can be effectively estimated; and the snaps are pressed to enable the two connectors to be respectively connected with wires of the fluorescent lamp and the ballast, connection is convenient and quick, and test is conveniently carried out.

Description

technical field [0001] The invention relates to the field of reliability testing of fluorescent lamp ballasts, in particular to a test device for simulating the rectification effect of fluorescent lamp tubes. Background technique [0002] As a kind of lighting device, fluorescent lamps are energy-saving light sources. It has the advantages of long life, high light efficiency, good color rendering and good use effect, so it is widely used in various airports. At the end of the life of the fluorescent lamp, due to the damage of a cathode filament or insufficient electron emission, the effect that the arc current of the lamp is often inconsistent in the continuous half cycle, that is, the rectification effect, will cause the ballast of the fluorescent lamp to be damaged after working for a long time. Therefore, the anti-fluorescent lamp rectification effect of the fluorescent lamp ballast is an important indicator to measure the reliability of the lamp. The anti-fluorescent l...
