摘要
荧光薄膜封装发光二极管(LED)是一种新的封装技术.这种技术通过分离荧光粉与芯片,解决了传统点胶工艺中LED光色不一致、荧光粉沉淀、不利于LED散热等问题,而且提高了荧光粉的热稳定性,极大提升了LED的光色品质.本文综述了荧光薄膜的制备方法及其在LED中的应用实例,对实际研究和应用有一定的作用.
Phosphor film packaging technology provides a new encapsulating construction for white LEDs. The phosphor separates from the LED chips in order to solve some issues in traditional dispensing process, such as inconsistent optical and color temperature properties, phosphor precipitate, and hard heat dissipation. Phosphor film packaging technology not only improves the thermal stability of phosphor, but also greatly enhances the optical and color temperature properties of LED. We summarize the preparation method of phosphor film and its application examples in LED, which will contribute to the actual research and application.
