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 Light intensity serves as the core optical indicator of lighting products, and how to measure light intensity lays the foundation for luminaire photometric testing, product energy efficiency certification, and lighting design simulation. Taking the LISUN LSG-1890B High Precision Goniophotometer (Luminous Intensity Distribution Curve) as the test instrument, this paper elaborates on the un...
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...
Abstract In the fields of lighting engineering design, luminaire research and development, and quality control, the spatial distribution characteristics of luminaire optical performance are the core basis for evaluating lighting effects, ensuring usage safety, and achieving energy-saving goals. Traditional photometric testing equipment struggles to fully capture the regular pattern of luminous int...
