Fluorescent powder component excited by blue light and LED lamp bead thereof

The invention discloses a fluorescent powder component excited by blue light and an LED lamp bead thereof. The fluorescent powder component is excited by a blue light chip with the wavelength of 440-450 nm, and the fluorescent powder component comprises blue-green fluorescent powder or cyan fluorescent powder with the peak wavelength of 490-510 nm, green fluorescent powder with the peak wavelength of 520-530 nm and yellow-green fluorescent powder with the peak wavelength of 540-560 nm, the peak wavelength of the orange red fluorescent powder is 590-610 nm, and the peak wavelength of the red fluorescent powder is 625-640 nm. According to the technical scheme of the embodiment, the requirements of high light efficiency, high color rendering and low blue light proportion can be well met. 本发明公开了一种蓝光激发的荧光粉组分及其LED灯珠，通过波长为440-450nm的蓝光芯片激发，所述荧光粉组分包括峰值波长为490-510nm的蓝绿色荧光粉或者青色荧光粉，峰值波长为520-530nm的绿色荧光粉，峰值波长为540-560nm的黄绿色荧光粉，峰值波长为590-610nm的橙红色荧光粉和峰值波长为625-640nm的红色荧光粉。通过上述实施例的技术方案，能够很好地达到高光效、高显色、低蓝光占比的要求。
