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.

2.0 Scope of testing

Photometric and electrical testing in accordance with IES LM 79-08 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.

Illustration of goniometer measurement geometry and coordinate

system. Sample is rotated through F lateral angles and through q

vertical angles.
