Measuring and analyzing LED performance

摘要

The measurement of the spatial luminous intensity distribu-tion of different types of light sources - including solid-state lighting (SSL) like LEDs - is important in lighting design and quality control. Everything from automotive headlamp design to technical plans for lighting rooms or parking lots is based on this data. In some specialized medical applications, like lightrntherapy, the light beam profile must also be known to design for effective targeting and dosimetry.
