Problems solved by technology

[0005] In addition, in the process of testing, the LED fluorescent material must be mixed with other materials (that is, called destruction) before the test can be carried out, and after use, it cannot be reused, which means that it must be discarded, which is very environmentally friendly

Abstract

The invention relates to a system for detecting light color and spectrum of a light-emitting diode (LED) fluorescent material and a method of the system, and belongs to optical instruments. By performing mutual calculation or synthesis (analysis) on various spectra through an analysis device which comprises a spectrum loading unit, a spectrum synthesis unit, a spectrum calculation unit, a spectrum storage unit and a chromaticity coordinates generation unit, the conversion efficiency, light color characteristic quantitative spectrum and light color of the LED fluorescent material can be detected in a direct and nondestructive manner without changing any type of the LED fluorescence test sample. Besides, poor-quality LED fluorescent materials are blocked from entering the production, to reduce the reject rate of light color products; and the white-light LED optical and spectral structures are fully simulated, and the white-light LED spectrum of the test sample is entirely separated to form an induced blue light spectrum and a fluorescence spectrum, which are independent from each other.

Description

technical field [0001] The present invention provides a light color and spectrum detection system for LED fluorescent materials, especially a direct test non-destructive and without changing any LED fluorescent test sample type, LED fluorescent material conversion efficiency and light color characteristics quantitative spectrum and light color The detection method, and the sampling is fast, does not consume redundant materials and manpower for making samples, and effectively filters bad LED fluorescent materials into production to reduce the output of bad light and color products. LED fluorescent material light color and spectrum detection system and its method . Background technique [0002] Previously, when testing LED fluorescent materials, the LED industry needed to emit light close to the actual product structure before further analysis could be done. Therefore, the test optical path (Optical Path) of the sample must be the same as the light-emitting path of the white ...
