Abstract As a new generation of solid-state lighting sources, LED quality directly determines lighting effect, energy efficiency, and service life. Opto-electro-color parameters are the core indicators for measuring LED quality. Lumen testers, as key equipment for detecting LED opto-electro-color parameters, play an irreplaceable role in quality control. This paper takes the LISUN LPCE-2(LMS-9000)...
Abstract EMC instruments form the core toolkit for verifying the electromagnetic compatibility (EMC) of electrical and electronic products. Their fundamental task is to precisely measure and evaluate the levels of electromagnetic interference (EMI) generated by equipment, ensuring it does not cause interference to other devices or the environment and possesses a certain degree of immunity. This a...
Abstract In the context of global market integration and harmonized technical standards, product safety and environmental durability have evolved from competitive advantages into fundamental requirements for market access. The IEC 60529:2013 standard, published by the International Electrotechnical Commission, is globally recognized for defining Ingress Protection (IP) ratings, providing a system...
Abstract Transient overvoltages and overcurrents caused by lightning strikes and grid switching operations are critical factors threatening the reliability of electrical and electronic equipment. The impulse voltage tester (also referred to as a surge generator) is a core electromagnetic compatibility (EMC) test instrument for simulating such high-energy transient interference and evaluating the ...
Abstract As a key equipment in industrial production, scientific research and testing fields, color measurement instruments directly affect product quality control and R&D efficiency with their measurement accuracy, stability and convenience. Taking the HSCD-860 Handheld Spectrophotometer (High-Precision Reflection) launched by LISUN GROUP as the research object, this paper systematically anal...
Abstract In the system of industrial product R&D, production quality inspection, and compliance certification, the environmental adaptability and reliability of materials and products are core indicators determining their market competitiveness and service life. As a key equipment for accurately simulating complex natural environments, climate chambers can accelerate the assessment of product ...
Abstract In lighting quality assessment, display device calibration, and various light source R&D, color temperature, as a core parameter describing the chromatic characteristics of a light source, is crucial for accurate measurement. The traditional colorimeter offers limited functionality, whereas modern optical measurement technology integrates its capabilities into more powerful portable ...
Abstract How to Perform the Salt Spray Test? This is a core technical question in evaluating the corrosion resistance of metallic materials, coatings, electronic components, and various industrial products. The salt spray test is a standardized test method that uses a sodium chloride solution to simulate marine or salt-laden atmospheric environments, accelerating corrosion to assess a product̵...
Abstract How to do ball pressure test? The Ball Pressure Test is a core safety assessment procedure used to evaluate the thermal deformation resistance of non-metallic components (e.g., insulating materials, enclosures, support parts) in electrical and electronic equipment. It is widely applied in quality control and safety certification for products such as plugs and sockets, luminaires, switches...
