The Hong Kong International Autumn Lighting Fair 2026, one of Asia’s most influential professional trade platforms for the lighting sector, concluded successfully. The exhibition gathered lighting brands, global buyers and laboratory technical service providers, focusing on hot industry demands including lighting optical inspection, power performance verification, EMC and reliability testing. LI...
Abstract Luminous intensity curve measurement is the fundamental step for luminaire optical performance evaluation, product certification and lighting simulation design. According to mechanical motion structure, goniophotometers are mainly divided into Rotation Luminaire Goniophotometer and moving mirror goniophotometer. These two types show obvious differences in mechanical motion logic, coordina...
Abstract Photometric performance testing of lighting products is an indispensable part of luminaire R&D, quality control and export certification. As the core instrument for obtaining full‑space luminous intensity distribution data of luminaires, the compliance of goniophotometer with domestic and international standards directly determines the validity of test results. The LISUN LSG‑6000 ...
Abstract On May 5, 2026, Brazil’s INMETRO officially issued Portaria nº 231/2026, replacing the old Portaria nº 69/2022 as the unified technical quality specification and conformity assessment regulation for LED light sources and LED luminaires. The biggest change in this revision is that LED luminaires are formally included in the scope of mandatory certification, instead of only regulating i...
Abstract: With the rapid development of new energy vehicles, energy storage power stations and consumer lithium battery industries, the safety, consistency and life assessment of battery cells and battery packs have become the industry’s key concerns. Internal resistance and DC voltage are the two core parameters characterizing battery health status. Battery test equipment can achieve synch...
Abstract: Luminous intensity is the most fundamental photometric parameter of lighting products, and the instrument that measures light intensity is an indispensable testing equipment for luminaire light distribution performance evaluation, product R&D and export certification. Conventional photometric testing equipment usually suffers from limitations such as incomplete test angles, limited ...
Abstract: With the rapid iteration of consumer electronic fast-charging technology, the power range of chargers and adapters keeps expanding, and the long-term operational stability and safety of products have become key points of quality control. The battery charger tester is the core equipment for completing factory accelerated aging and reliability durability test of full-specification power s...
Abstract: Materials and electronic products are subjected to complex climatic stresses such as high and low temperatures, humidity alternation and abrupt temperature changes during actual service. Conventional room-temperature tests cannot effectively evaluate the failure risks of products under extreme working conditions. As core equipment for artificial climate simulation, the environmental tem...
Abstract UL 94 is a widely‑adopted international specification for flammability classification of plastic materials, and the UL 94 Flammability Test Apparatus serves as core testing equipment for material laboratories, third‑party certification bodies and quality‑control departments of electrical and electronic manufacturers. The horizontal‑vertical flame tester is a flammability‑testi...
