摘要
LED因其独特的优点被广泛应用,因此,LED可靠性问题尤为重要,而相关色温是研究LED可靠性的一项重要参数。文中介绍了LED的优点及应用,针对LED的相关色温使用傅里叶逼近、高斯逼近、多形势逼近及正弦曲线逼近等方法进行曲线拟合,并采用K-均值聚类、文本聚类和模糊C聚类等方法进行聚类分析,说明了对LED可靠性问题的研究及器件的筛选与检测的重要意义。
LED is widely used by its unique advantages. Therefore, the reliability of LED is extremely impor- tant. The correlated color temperature （CCT） is an important parameter of reliability. This paper describes the ad- vantages and applications of LED. Curve fitting is performed for CCT by Fourier, Gaussian, Multi-form, Sinusoidal approximation and cluster analysis is made by K-means clustering, text clustering and FCM clustering. It provides great convenience for the research of reliability and screening of devices.
