Abstract In the actual operating environment of electrical and electronic equipment, high-energy transient interference caused by natural lightning induction and large-capacity inductive-capacitive load switching poses a serious threat to the stable operation of equipment power cords and internal connecting wires. As a core testing device, the surge generator working principle can simulate such i...
Abstract In the lighting industry, the photometric, colorimetric, and electrical parameters of luminaires are core indicators for measuring product quality and performance, directly influencing lighting effects, energy efficiency, and user experience. As a professional testing equipment integrating a high-precision spectral radiometer and an integrating sphere system, the integrating sphere set...
Abstract In the electrical and electronic industry as well as the field of material research and development, the flame retardant safety performance of products is directly related to their safety and reliability during use. As professional flame retardant performance testing equipment, flammability testing labs can accurately simulate the needle – shaped flame scenarios caused by local o...
Abstract In the fields of material research and development and product quality testing, the impact of climatic environments on performance is crucial. As a core testing equipment, humidity and temperature stability chambers can accurately simulate various climatic conditions such as heat resistance, cold resistance, dry resistance, and humidity resistance. Through controllable temperature and ...

This paper takes the LISUN IK07-10 IK Impact Rating as the research object, systematically expounds its technical principles, structural...
Abstract:Aiming at the unclear difference in optical performance among five types of mainstream lighting fixtures in the market, namely bulb lights, PAR lights, LED lights, street lights and tubes, this study adopted the LISUN LMS-6000 Digital Lux Meter (full-function version LMS-6000SF) to conduct a systematic test on key optical parameters of the five types of fixtures, including illuminance,...
Abstract With the widespread application of electronic equipment, electromagnetic compatibility (EMC) has become a key indicator in product design and production. This paper takes the LISUN EMI-9KB EMI Receiver Test System as the research object, and analyzes in detail its technical characteristics, testing capabilities and application scenarios. The system adopts a fully enclosed structure and hi...
Abstract: This paper elaborates on the working principle of XRF analysers (Energy Dispersive X-Ray Fluorescence Spectrometers), which involves analyzing the wavelength and intensity of characteristic X-rays emitted by test samples. It determines the elements contained in the sample based on the differences in the wavelength of characteristic X-rays of different elements, and measures the elemental...
Abstract: With the rapid development of electronic technology, the number of electronic devices is increasing daily, and their operating frequencies are becoming higher, leading to an increasingly complex electromagnetic environment. Electromagnetic interference (EMI) issues have become a critical factor affecting the reliability and safety of electronic equipment. Therefore, conducting strict Ele...
