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 Impedance characteristics are critical to evaluating the performance of electronic components such as ferroelectric crystals, piezoelectric ceramics, piezoelectric crystals, and ultrasonic transducers. The impedance analyzer circuit, as the core functional unit of an impedance analyzer, determines the accuracy, stability, and efficiency of impedance measurement. This paper takes the LISUN...
Abstract Goniometer light measurement serves as the cornerstone of accurate optical performance evaluation for solid-state lighting (SSL) products. With the 2025 release of ANSI/IES LM-79-24, the latest iteration of SSL photoelectric testing standards, manufacturers require advanced goniometric systems to meet updated regulatory demands while maintaining compatibility with prior benchmarks like LM...
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...
