3 Terms and Definitions

GB/T 5838, GB/T 14633 and defined by the following terms and definitions apply to this document. 3.1 Matching pink comparisonphosphors Supply and demand mutually agreed, after the performance of the product quality is relatively calibrated for measuring phosphors, which indicators should meet the secondary characteristics The demand side, key performance indicators and measured powder close. 3.2 Secondary characteristics phosphorsapplicationcharacter After the phosphor used in energy-saving lighting products, its application performance and characteristics of light and color parameters. 3.3 Color drift colorshift Ignite under specified conditions, the initial color coordinates at a particular time during the life of the lighting color coordinates (xr, yr) and the lamp (X0, y0) of the poor.

4 principle of the method

Powder to be tested and compared to the powder in the same sample tube made of lamp production technology, the visible - near infrared spectroscopy system to be detected Photometric properties measured powder on powder lamp color difference sample characteristics, and color retention ratio and drift performance ratio, which measured powder characterization and comparison Powder quality differences.
