摘要
柔性LED灯丝是一种新型的LED光源,将多颗倒装芯片串联封装在柔性透明基板制备成可任意弯曲与拉伸的灯丝,实现360°全角度发光。解决了刚性LED灯丝吸光、可塑性差、结构复杂、制造繁琐等问题,使LED灯丝得到进一步的应用与推广,推动了LED灯丝灯的发展。综述了柔性LED灯丝在封装结构、封装材料、封装工艺、散热技术等方面研究状况,对实际研究和应用有一定的指导意义。
The flexible LED filament is a new type of LED light source.Arbitrary bending and stretching filament was prepared by encapsulating multiple flip chips in series in the flexible transparent substrate,so as to realize full angle illumination of 360°.The problems of rigid LED filament such as light absorption,poor plasticity,complex structure and cumbersome manufacturing were solved,which further ensured the application and popularization of LED filament,and promoted the development of the LED filament lamp.The present research status of flexible LED filament in packaging structure,packaging materials,packaging technology,heat dissipation technology was summarized,which was of certain guiding significance for the practical research and application.
