Abstract

The invention is appropriate for the detection field of an LED (Light Emitting Diode) nixie tube, and provides a detection device and method of the LED nixie tube. According to the embodiment of the invention, with the adoption of the LED nixie tube detection device which comprises a central processing module, one or more driving detection modules which are same with position selecting ends of the detected LED nixie tube in quantity and a detection result display module, the central processing module is matched with the one or more driving detection modules to judge the polarity, the eligibility and the plugging condition of pin positions for the detected LED nixie tube, so that the device is simple in circuit structure and low in cost. The one or more driving detection modules are driven by a constant current source, so that the LED nixie tube works stably in the detection process and the service life of the nixie tube is not affected. In addition, result information is further displayed and judged through the detection result display module for the convenience of detection personnel to obtain the detection result intuitively, so that the detection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of LED digital tube detection, in particular to an LED digital tube detection device and method. Background technique [0002] At present, as a new type of light source, LED is widely used in various fields because of its advantages of high brightness, low power consumption and long life. Among them, LED digital tube, as a display module, is also used in various industries equipment and household appliances. In order to ensure the quality of LED digital tubes, LED manufacturers will conduct quality inspections on LED digital tubes before leaving the factory. Quality requirements for LED digital tubes. [0003] The LED digital tube quality detection method provided by the prior art needs to be manually carried out by the detection personnel, which is prone to missing detection and virtual side, and the detection efficiency is low; while most of the detection instruments used are relatively heavy and must be equipped ...
