摘要
贴片式发光二极管是一种新型表面贴装式半导体发光器件,贴片式封装的LED又分为CHIP、TOP、SIDEVIEW等若干种类型,贴片式LED除了有着直插式LED的所有优点外,更以体积小、散射角大、发光均匀性好,散热性好等特点被广泛的应用于各种场合,例如显示屏、信号灯、家用照明上很多都已经采用了贴片式LED。本文从多个角度切入,介绍了贴片式LED的市场状况和发展趋势,同时探究贴片式LED的封装特性及最新研究成果,分析研究贴片式LED节能灯的驱动电路技术,并且将它与直插式LED节能灯做了光电特性对比测试,使我们能更全面的掌握当今贴片式LED的发展现状。相信贴片式LED的广泛应用和飞速发展,将引领当今LED照明行业朝着更轻薄、更高效的方向发展。
SMD LED is a new surface-mount semiconductor device,and its package is divided into several types,such as CHIP,TOP and SIDEVIEW.In addition,not only with all the advantages of DIP LED,but also its small size,large scattering angle,good light uniformity,and good heat dissipation characteristics,so it is widely used in various occasions,such as display screen,signal light,home lighting have been used in SMD LED.This article is presented from several parts,introducing the SMD LED market conditions and trends,while exploring the package features of SMD LED and the latest research results,and analysis SMD LED energy saving lamp＇s driving circuit technology,and I make a comparison between the SMD LED and the DIP LED by photo-electricity property＇ test,so that we can grasp the current situation of the SMD LED development easily.I believe that the widespread of SMD LED applications and rapid development of LED lighting industry will lead the current LED lighting industry development towards lighter,more efficient.
