WORKSHOP 2: LED Lighting Standards, Methods of Measurements, Projections, and Measurement Equipment
Tuesday, February 28, 2017: 8:00 AM - 12:00 PM
This workshop contains two sections. The first section is the overview and the update for the latest standards for LED and LED lighting from both industry and the US governments. In particular, the recent work being carried at ANSI, IESNA, NEMA, UL, IEEE, SEMI, ASABE, US EPA, etc. for LED applications. The second section introduces the standardized methods of measurements for LED packages and LED lighting systems. It provides detailed explanations for the objectives, procedures, and rationale for measuring, testing and projecting the long-term behaviors of the LEDs and LED lighting characteristics including photometry, colorimetry, luminious flux and color maintenance, thermal resistance, failure rate, etc. Also, the measurement equipments and instruments, research and standardization work in CIE and IES on the key measurement instruments will be introduced. The best practices including uncertainties for LED and lighting measurements will also be discussed.
