白光LED具有低压、低功耗、高可靠性和长寿命等一系列优点,是一种符合节能环保的绿色照明光源。现阶段的白光LED显色指数低、色温较高,限制了白光LED在室内照明等领域的发展,而红色荧光粉能对白光LED的显色指数的提高及色温的改善影响极其显著。主要介绍白光LED用红色荧光粉几大主要体系的发光性质及最新发展现状。
White LED with a series of advantages of low voltage, low power consumption, high reliability and long life, is a green light source in line with energy saving and environmental protection. At this stage of the white LED low color rendering index, high color temperature, limiting the white LED indoor lighting and other areas of development, and the red phosphor white LED can improve the color rendering index and color temperature to improve the impact of extremely significant. Mainly introduces the red phosphor of white LED several major systems of luminescent properties and the latest development status quo.
