Abstract Material aging, driven by sunlight, temperature, and humidity, poses significant challenges to product durability. The LISUN XD-150LS Xenon Lamp Aging Test Chamber addresses this by integrating the core principle of “natural simulation + accelerated aging”. Equipped with a xenon arc lamp that reproduces over 90% of natural sunlight’s full spectrum, this chamber accurately re...
Abstract With the rapid development of industries such as electrical and electronic equipment, household appliances, lighting, and information technology devices, the fire risk caused by faults like circuit short circuits and component overheating inside equipment has become increasingly prominent. Fire safety has thus become a core requirement for product R&D, production, and market access. A...
Type C Goniophotometer systems are used in preference in road and out light testing since they provide a convenient combination of geometry, angular coverage, and alignment that is flexible to the real-world luminaire requirements. At the beginning it is necessary to mention the goal of the measurement. The essence of roadway lighting specifications is the luminous intensity measurement of various...
Any laboratory, which provides credible characterization of LED products, is dependent on lighting test equipment. The first question when you are designing a LED testing program is what do you want to prove by the measurements. Many projects require that for leading to occur, performance, color quality, temporal stability and electrical efficiency be answered in ways which are repeatable and repo...
Abstract Electrostatic discharge (ESD) is a common electromagnetic interference source during the operation of electrical and electronic equipment, which may easily cause abnormal performance, functional failure, or even permanent damage to the equipment. Its immunity test has become a core link in product reliability verification. As a key instrument for standardized testing, the ESD generator pl...
A thermal chamber is a key laboratory equipment that is utilized to analyze the product behavior under temperature stress. Diminished time, duration of thermal exposure In accelerated aging and durability tests fine control of ramps of temperatures and fine control of dwell times and cycling profiles to compress years of thermal exposure in weeks and months. Where humidity is also of great concern...
Abstract Salt spray corrosion is one of the core factors leading to metal material failure and reduced product reliability in marine environments and industrial scenarios. Accurately evaluating the salt spray corrosion resistance of materials and products is crucial for ensuring product service life. As a key environmental simulation testing equipment, salt spray chambers play an irreplaceable rol...
A good and consistent EMC measurement equipment is crucial in a lab doing compliance test and product development. One component of that ecosystem, which is critical, is the LISN which will serve to fix the line impedance and decouple the equipment under test with supply noise. When the routine maintenance is not taken care of, repeatability of measurements is lost, traceability, and safety are ch...
Abstract With the upgrading of the lighting industry towards high efficiency and intelligence, the optical-color performance of LED lamps, bulb lamps, and street lamps has become a core indicator for measuring product quality. The portable spectrometer, leveraging its portability and high precision, has emerged as a key device for on-site testing and quality control. This paper takes the Lisun LMS...
