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 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 The performance evaluation of lighting products relies on the acquisition of complete photometric, colorimetric and electrical indicators. As core instruments for lighting inspection, LED test equipment supports comprehensive performance testing of both conventional gas light sources and solid-state LED light sources. Taking the LISUN LPCE-2 LED CCD Rapid Photometric, Colorimetric & E...
Abstract LED light sources have gradually replaced traditional energy-saving lamps, fluorescent lamps, HID high-pressure gas discharge lamps and cold cathode fluorescent lamps, and become mainstream products for general lighting, commercial lighting and automotive lighting. The core method for light source quality control is integrated testing of complete photometric, colorimetric and electrical p...
Abstract: Lumen measurement serves as the core procedure for photometric inspection of lighting sources, which directly determines the accuracy of key indicators including luminous flux and luminous efficacy. Taking LISUN LPCE-2(LMS-9000) high-speed CCD integrated photometric, colorimetric and electrical test system as the research object, this paper carries out integrated parameter testing and an...
Abstract: Lumen measurement is the core procedure for luminous flux detection of lighting products, which directly determines the evaluation of light brightness, luminous efficacy and energy efficiency class. Taking the LISUN LPCE-2(LMS-9000)High Precision Spectroradiometer Integrating Sphere System as the experimental platform, this paper carries out lumen measurement and comprehensive opto-ele...
Abstract: Lumen measurement is a core method for evaluating the photometric performance of lighting sources, which directly reflects the luminous capacity and energy efficiency level of light sources. Taking the LISUN LPCE-2 (LMS-9000) LED CCD Rapid Photometric, Colorimetric and Electrical Comprehensive Testing System (for details, please visit: https://www.lisungroup.cn/products/712.htmll) as th...
In 2026, the Bureau of Indian Standards (BIS) completed and issued the revised standard IS 16102-2:2026 for the operational performance of outdoor LED lighting equipment. As a core mandatory standard for India’s outdoor LED lighting sector, this update further refines technical requirements and improves test specifications on the original basis. It aims to enhance the reliability, safety, and ad...
On February 24, 2026, the Bureau of Indian Standards (BIS) officially released the revised safety standard for self-ballasted LED lamps for general lighting, IS 16102-1:2026, which replaces the 2012 version. It specifies that the transition period for the old and new standards will last until August 2, 2026, after which the old standard will be formally abolished. As the core mandatory safety stan...
Abstract: As the core basis for photoelectric performance compliance certification of solid-state lighting products, the LM-79 Test Report has become a key technical document for products to enter the global market. The LISUN LPCE-2 High-Precision Spectroradiometer & Integrating Sphere System is a professional comprehensive testing instrument for optical, color and electrical parameters of lig...
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)...
The high rate of development of solid-state lighting has generated the demand of precise and dependable luminous flux measurements. To develop energy-saving LED systems, the optical output, color stability, heating impacts and reality lumen depreciation have to be evaluated accurately. The most common method of this measure is one found on an integrating sphere which is an optical enclosure that i...
