Abstract In the R&D, production, and factory inspection of electronic and electrical products, lamps, electrical cabinets, and other equipment, the UL rain test is a key method to evaluate the physical performance and safety reliability of products under simulated rainy weather conditions. Traditional rain test equipment has problems such as low standardization, insufficient precision in test parameter control, and non-standard operating procedures, which easily lead to deviations in test results and affect the judgment of product compliance. This paper takes the LISUN JL-UL Water Spray Test Device as the core, and combined with its design features that comply with international standards such as UL, ANSI, and CSA, systematically expounds the complete process of “how to conduct UL rain test“, including key links such as pre-test preparation, equipment debugging, parameter setting, test execution, and result determination. At the same time, by analyzing the technical parameters and ...
Abstract In the production and quality control of transparent and translucent materials such as plastics, films, glass, and LCD panels, color consistency, haze, and light transmittance are core indicators for measuring product performance. Traditional testing equipment often suffers from limitations such as single function, complex operation, and insufficient data accuracy, making it difficult to meet the demand for one-stop measurement. This paper takes the LISUN HM-700 Haze Light Transmission Meter as the research object, and combines its technical parameters, functional characteristics, and application scenarios to conduct a detailed analysis of the core advantages of this equipment in the detection of transparent and translucent materials. By interpreting the equipment’s standard compliance, measurement accuracy, operational convenience, and scenario adaptability, this paper expounds its practical value in multiple industries, providing technical references for enterprises to impro...

Abstract In the fields of lighting engineering design, luminaire research and development, and quality control, the spatial distribution characteristics of luminaire optical performance are the core basis for evaluating lighting effects, ensuring usage safety, and achieving energy-saving goals. Traditional photometric testing equipment struggles to fully capture the regular pattern of luminous intensity distribution of luminaires in three-dimensional space. However, the goniophotometer system, with its technical advantages of “high-precision spatial scanning + multi-parameter synchronous calculation”, has become a key device to solve this pain point. This paper takes the LISUN LSG-1890B High-Precision Goniophotometer System (Luminous Intensity Distribution Curve) as the research object, systematically expounds its technical principles and application scenarios in the testing of 15 core parameters such as luminous intensity data, regional luminous flux, luminaire efficiency, and glare r...
Abstract Light illumination measurement is a critical technical process in fields such as lighting engineering, industrial production, and environmental monitoring, as it directly determines the rationality of light environment design and the quality of related products. Portable CCD spectroradiometers have become the core equipment for on-site light illumination measurement due to their advantages of portability, high precision, and multi parameter testing. This paper takes the LISUN LMS-6000 Portable CCD Spectroradiometer as the research object, systematically expounds on its technical principles, functional characteristics, and application methods in light illumination measurement. Through detailed analysis of its parameter indicators and actual test data, it verifies the instrument’s accuracy and reliability in light illumination measurement.
