Abstract: In the production and quality inspection of lighting products, power equipment, and outdoor application equipment, the mechanical impact strength of the shell is a core indicator that determines the safety, reliability, and service life of the products. This paper takes the LISUN IK07-10 IK Impact Rating as the research object, systematically expounds its technical principles, structural characteristics, and applicable scenarios, and focuses on analyzing the specific application processes of this equipment in the IK strength testing of lamp housings, the impact testing of metal sheets of power distribution cabinets, and the verification of impact resistance of outdoor equipment. By comparing the parameter settings and test results of different test objects, the testing accuracy and stability of the equipment within the energy range of 2J-50J are verified, providing a scientific basis and practical reference for product quality control in related industries. 1.

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, correlated color temperature (CCT), color rendering index (Ra), peak wavelength, flicker depth and retinal blue light hazard. Through scientific design of the test scheme, accurate data collection and comparative analysis, the performance advantages and applicable scenarios of various types of fixtures were clarified. The results show that street lights have outstanding performance in illuminance and anti-flicker, PAR lights have the best color rendering index, and LED lights have balanced comprehensive performance. This study provides reliable data support and technical reference for lighting ...
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 highly conductive materials, achieving excellent shielding effect and fundamentally solving the problem of the equipment’s own interference. Through test procedures and report formats that comply with international standards, the EMI-9KB can meet the requirements of multiple specifications such as CISPR, GB, and FCC, providing reliable support for EMC certification of electronic equipment. Actual test data shows that the measurement accuracy of the system in the 30MHz-1GHz frequency band can reach ±1.5dB, and the repeated test deviation is less than 0.8dB, demonstrating excellent stability and a...
This statutory body in Tanzania is rooted in a profound legal foundation, emerging in accordance with the Standard Act No. 3 promulgated by Parliament in 1975, and officially commenced operations on April 6, 1976. Fully funded by the government and affiliated with the Ministry of Industry and Trade, the institution has established a sophisticated organizational structure, comprising six core departments: Process Technology Standards, Engineering Standards, Quality Management, Testing and Calibration, Documentation, and Administration. From standard drafting to metrological calibration, and from quality control to skills training, these departments operate in synergy, serving as the backbone for promoting industrial and commercial standardization and fortifying quality and safety safeguards. As an important member of multiple international standardization organizations, the institution shoulders the responsibility of formulating and managing Tanzania’s national standards, which cover al...
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 and EN 55015 standards, is optimized for testing lighting and similar equipment across a frequency range of 30 MHz to 300 MHz. This study details its technical specifications, working principle, performance characteristics, and practical application in EMC test setups. Comparative data and experimental results demonstrate its superior decoupling efficiency (>30 dB) and impedance matching (50 Ω), validating its role as a cost-effective and reliable solution for conducted RF immunity evaluations. 1. Introduction With the proliferation of wireless communication and power electronic systems, the...
