IESNA LM -79 • 자세한 내용 - A study on the comparison of correlated color temperature measured by colorimeter and spectrophotometer, Ki Jin Kwon, KIIEE Annual Spring 2011 - A study on the comparison and analysis of correlated color temperature using spectroradiometer spatially scanned and spectrum measurement system with sphere-spectroradiometer , Ki Jin Kwon, KIIEE Annual Spring 2011 - Study for measuring Solid State Lighting product Correlated Color Temperature using Colorimeter Spatially Scanned , Ki Jin Kwon, 2011 Lighting Conference of China, Japan and Korea
IESNA LM -80 • IESNA Approved Method for Measuring Lumen Maintenance of LED Light Sources • Specify procedures for determining lumen mainenance of LEDs and LED modules (but not luminaires) related to effective useful life of the product. • LM-80 is a component (package, module or array) level test • Lumen maintenance (life) determined by in-situ temperature measurements of components.
IESNA LM -80 • Will be three test temperatures (Tc): 55 ℃, 85 ℃ and one determine by manufacturer. • Test may be conducted at the same time as UL 1598/153
