Foreword

GB/T 14634 "light rare earth trichromatic phosphors Test Method" is divided into seven sections.

--- Part 1. Determination of relative brightness;

--- Part 2. Determination of emission peak and color performance;

--- Part 3. Determination of thermal stability;

--- Part 4. Electric sensing particle size distribution measurement;

--- Part 5. Determination of density;

--- Part 6. Determination of specific surface area;

--- Part 7. Determination of thermal quenching. This is Part 2. This part is GB/T 14634.2-2002 "light rare earth trichromatic phosphors Test Method for Determination of emission spectra and colorimetric properties." Amendments. This section compared with the GB/T 14634.2-2002, the main changes are as follows:

--- Range changed to "This section applies to light emission peak trichromatic phosphors, chromaticity coordinates, color rendering index, chromaticity of Capable of measuring "parameter;

--- Normative references added CIE15 colorimetry, CIE1931 standard colorimetric observer, CIE1976L * u * v * color space Room and u ', v' uniform chromaticity scale diagram;

--- Adjust some analysis condition;

1 Scope

GB/T 14634.2-2010 is the Chinese national standard on test methods of rare earth three-band phosphors for fluorescent lamps - part 2: determination of emission dominantpeak and chromaticity, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 9 August 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2011. Classification: ICS 77.120.99, CCS H14. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

GB/T 14634 This part provides light emission measuring method and chrominance peak performance trichromatic phosphors. This section applies to light emission peak trichromatic phosphor was measured chromaticity coordinates, color rendering index, chromaticity performance parameters.

3 PRINCIPLE OF THE METHOD

Sample 253.7nm UV excitation emit visible light, the spectral radiation tester spectroscopic and photoelectric conversion, the monochromatic letter No. converted into electrical signals, and then by standard light correction to obtain an electrical signal corresponding to the light intensity value; at a certain wavelength interval measured the entire visible spectrum, The sample obtained in the entire visible light emission relative spectral power distribution, and then calculate various performance parameters chroma CIE15-2004.
