Abstract In the production and R&D process of electrical and electronic products, lamps, electrical cabinets, and electrical components, their operational reliability in outdoor or humid environments is of crucial importance. The LISUN JL-UL UL Environment Test Equipment Water Spray Head Piping Test is manufactured in strict accordance with a series of international authoritative standards. It can accurately simulate rainy weather conditions and conduct comprehensive tests on the physical properties and other related performances of various products. This paper will conduct an in-depth analysis of the design standards, structural composition, and technical parameters of this equipment, elaborate on its role and application process in product testing, and demonstrate its significant value in ensuring product quality and promoting the standardized development of the industry by combining actual data and diagrams. It aims to provide a reference for product design, improvement, verifi...
Abstract In environments where electronic and electrical products, automotive components, and lamps operate, dust accumulation and infiltration often lead to performance degradation, functional failures, or shortened service life. The dustproof testing machine, as a core equipment for simulating dust climate conditions, plays a crucial role in verifying product dustproof performance and guiding product design optimization. This paper takes the LISUN SC-015 Dustproof Testing Machine (Sand Dust Chamber) as the research object, systematically elaborates on its application scope, compliance standards, structural design, technical specifications, and test implementation methods. Through detailed analysis of its functional characteristics and practical application value, this paper aims to provide a comprehensive reference for researchers and engineers engaged in product dustproof performance testing and quality control. 1. Introduction With the rapid development of industries such as electr...
This company is Southeast Asia’s leading LED luminaire manufacturer and supplier. Over the years, we endeavoured to supply high-quality lighting and related products to the international market, earning a stellar reputation for our high quality and becoming an evergreen brand. This company production plant is located in Pusing, Perak, Malaysia, covering 7 acres. As a factory endorsed with numerous professional certifications, our production environment strictly adheres to relevant certifications and official standards. It is the first manufacturer in Malaysia’s luminaire industry to produce downlights. This successful collaboration began at an industry trade show, where the client first learned about our products. Their interest grew, and they later sent their China-based colleagues to gain a deeper understanding of our offerings and discuss equipment requirements. The client primarily needed to test downlights and other lighting fixtures, all under 1.5 meters in size. Initially, they ...
Abstract Light-Emitting Diode (LED), as a new generation of solid-state lighting source, is widely used in various fields due to its advantages of high efficiency, energy saving and environmental protection. Its luminous flux maintenance rate and aging life are core indicators for measuring product quality. This paper takes the LISUN LEDLM-84PL LED Optical Aging Test Instrument as the research object. Designed in accordance with the IES LM-84 and TM-28 standards, this instrument integrates high-low temperature environment simulation, photoelectric parameter collection and life prediction functions. The paper elaborates on the design basis, hardware composition and working principle of the instrument, focuses on analyzing the life calculation method based on the Arrhenius model and TM-28 standard, and verifies the instrument performance through practical test cases. The research shows that the instrument can realize long-term stable monitoring of photoelectric parameters and rapid aging...
