3 2.0 Scope of testing Photometric and electrical testing in accordance with IES LM IES Approved Method for the Electrical and Photometric Measurements of Solid-State Lighting Products. Measuremets are made using the sphere -spectroradiometric test method and the goniometer - spectroradiometer test method. 2.1 Test protocol and data reduction 1. Sphere-spectroradiometer measurements are reported for all values except luminous intensity distribution and results derived from luminous intensity distribution measurments. 2. Sphere measurements are made in a 40'' integrating sphere with geometry as shown below. Absorption correction measurements are applied to all sphere measurements. 3. Luminous intensity distribution measurements are made with a a type C goniometer coordinate system (reference IESNA LM-75) in the geometry shown below. 4. Data is reported for the 380nm to 780nm spectral range with a 1 nm resolution. 5. Test samples are allowed to reach electrical and photometric stabilization per LM-79 requirements prior to measurement. 2.2 Integrating sphere and goniometer geometries Illustration of sphere measurement geometry. Optical measurements are made via a spectroradiometer located on a satellite sphere at the equator. An absorption correction measurement is applied to each measurement. Illustration of goniometer measurement geometry and coordinate system. Sample is rotated through F lateral angles and through q vertical angles. in full without permission of. Page 3 of 13
