Automatic test system for lamp safety regulations

Abstract

The invention discloses an automatic test system for lamp safety regulations. The system comprises an input/output test unit, an input test unit, a harmonic distortion test unit, an output load test unit, a full-load output current test unit, a leakage current test unit, an output current and power test unit, a withstand voltage test unit, an impedance test unit, a maximum output voltage test unit, a maximum input voltage test unit and a capacitor discharge test unit; a PLC is used for acquiring a user instruction and controlling each test unit to test according to the program; a touch screenis used for communicating with the PLC controller, and acquiring a user instruction through the configuration picture, so that the PLC controller enables the corresponding test unit to work and feedsback the control state of the PLC controller on the test unit. According to the invention, the most common 12 detections can be carried out in sequence, the manual operation is replaced to the greatest extent, the efficiency is improved, the detection process is rigorous, the data is real, the efficiency can be improved by about 20 times, the test efficiency is high, and the method is suitable forpopularization.

Description

technical field [0001] The invention relates to the technical field of lamp testing equipment, in particular to a lamp safety automatic testing system. Background technique [0002] At present, many lighting safety certification organizations in the world, such as CCC (China Compulsory Certification), UL (Underwriters Laboratories of the United States), CAS (Canadian Standards Association), ETL (ETL Testing Laboratory Company), TUV (German Technical Supervision Association), SGS (SGS General Standard Technical Service Co., Ltd.)..., all test whether their products meet the requirements according to the standards of the corresponding countries and regions. Each certification body is manually tested by engineers to ensure the rigor of the process and the authenticity of the data. However, with the development of lighting technology, the increase of business volume, the excessive labor of manual inspection, and the long project cycle caused by low efficiency have become the ob...

Problems solved by technology

[0008] Through circuit design to test bulbs, drivers and lamps, it takes 14.5 hours to complete the test of each model product one by one; and according to the requirements of relevant standards, samples need to work for at least 0.5 hours before testing, which caused Additional time wasted; during the inspection process, engineers need to perform different inspections at different stations, which in turn causes unnecessary labor

[0009] In addition to the above, there are only single-function testing equipment with networking functions on the market, which can no longer meet the inspection items of various lighting safety regulations, let alone meet the requirements of different testing institutions; resulting in insufficient comprehensive testing and large limitations
