Abstract

The invention discloses an LED lamp flicking testing system and an implementation method thereof, and belongs to the technical field of testing. The LED lamp flicking testing system comprises a power source module, a sensor linear array unit, a signal front-end processing unit and calculating equipment. The sensor linear array unit is arranged at the top inside a curtain through a height adjustable support. The curtain is arranged at the upper portion of a conveying belt. The curtain and the conveying belt form a darkroom, and the sensor linear array unit is composed of illuminance sensors. The power source module provides power for the illuminance sensors, the signal front-end processing unit and the calculating equipment in the testing system, and ensures that each functional unit works normally. The sensor linear array unit is an array formed by the illuminance sensors which are high in flexibility and high in response speed.

Description

technical field [0001] The invention relates to a flicker test system of an LED lamp and a test method thereof, belonging to the technical field of test. Background technique [0002] Incandescent lamps, fluorescent lamps and halogen lamps are all powered by alternating current, especially after the tungsten filament of the incandescent lamp is heated, a small instantaneous change in the power supply will not cause a change in the illuminance of the incandescent light, that is to say, a small instantaneous change in the power supply will not cause the incandescent lamp to change. visual flicker. The LED light is powered by a constant current source, and the time response of the LED light is very fast. A slight change in the power supply will cause a change in the illuminance of the LED light, so that the LED light will flicker. [0003] At present, the stroboscopic test of AC fluorescent lamps is carried out by using the PR-110 continuous and fast sampling transient photome...
