White light emitting diodes (wLEDs) have been widely used as the green lighting sources. The commercial wLEDs devices are mainly achieved through the combination of blue emission chips and yellow phosphors, which offer advantages of high efficiency and long lifetime. However, the color rendering index (CRI) of traditional wLEDs is low due to the lack of red components. In recent years, with the improvement of the quality of life, a lot of efforts have been paid to improve the performance of wLEDs devices related to CRI, correlated color temperature, light uniformity, luminous flux, etc. In this article, we summarize the recent advances on the optimization of wLEDs toward healthy lighting. Brief introductions on the fundamentals of healthy effect of lighting are presented, followed by discussions of current methods to realize wLEDs devices. Special overviews on strategies for luminescent materials of wLEDs in recent years are presented. The opportunities and challenges in the future development of wLEDs lighting devices are also discussed.
白光发光二极管（wLEDs）已被广泛用作绿色照明光源。商用wLEDs器件主要通过蓝色发光芯片和黄色荧光粉的组合来实现，具有高效率和长寿命的优点。然而，由于缺乏红色成分，传统wLEDs的显色指数（CRI）较低。近年来，随着生活质量的提高，人们在提高wLEDs器件与CRI、相关色温、光均匀性、光通量等相关性能方面付出了很多努力。在本文中，我们总结了wLEDs朝着健康照明优化的最新进展。介绍了照明健康效应的基本原理，随后讨论了实现wLEDs器件的当前方法。对近年来wLEDs发光材料的策略进行了特别综述。还讨论了wLEDs照明器件未来发展中的机遇和挑战。
