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...
Abstract Salt spray corrosion is a major cause of material failure in marine environments, automotive industries, and industrial production fields. Accurately evaluating the salt spray resistance of materials and coatings is crucial for ensuring product durability and reliability. This paper takes the LISUN YWX/Q-010 Cyclic Corrosion Chamber as the research object, systematically expounding its wo...
Abstract Dust intrusion is a major threat to the reliability and service life of products in industries such as electronics, electrical engineering, and automotive manufacturing. The sand dust test chamber serves as a critical tool to simulate dusty environmental conditions, evaluate product dustproof performance, and verify compliance with industry standards. This paper focuses on the LISUN SC-01...
Abstract The flammability test for plastics is a fundamental assessment in material science and product safety, particularly for components used in electrical and electronic appliances. Among various testing methods, the glow-wire test stands out for its ability to simulate thermal stresses caused by overheated or glowing parts in equipment. This paper explores the glow-wire test as a physical the...
Abstract Conducted radio frequency (RF) immunity testing is a critical component of electromagnetic compatibility (EMC) compliance, ensuring electronic equipment operates reliably in RF-polluted environments. This paper focuses on the CDNE for Conducted RF Immunity test, with a specific analysis of the LISUN CDNE-M316 Coupling and Decoupling Network. The CDNE-M316, designed to meet CISPR 15:2018 a...
Abstract With the widespread application of DC-powered electronic and electrical equipment in fields such as industrial control, automotive electronics, and renewable energy systems, the stability and reliability of these devices under abnormal power supply conditions have become crucial. Voltage dips and short interruptions at the DC power input port are common electromagnetic disturbance scenari...
