本发明公开了一种多波长芯片组合激发的LED光源,包括支架或基板,设置在所述支架或基板上的不同波长的LED芯片,以及设置在所述LED芯片上的荧光粉;所述LED芯片的波长为涵盖在400-480nm之间范围的混合波长。本发明的白光LED光源将不同波长范围的芯片有规律的组合并激发其相应的荧光粉实现了降低有害蓝光占比,从而避免了蓝光对人眼的危害。本发明的LED光源在增加显色及迎合了人体昼夜节律的同时降低了有害蓝光占比,提供了更高品质、更加健康的照明环境。
The invention discloses a LED light source excited by a combination of multi-wavelength chips, which comprises a bracket or a substrate, a LED chip with different wavelengths arranged on the bracket or substrate, and a phosphor arranged on the LED chip; The wavelength of the LED chip is a mixed wavelength covering the range of 400-480nm. The white LED light source of the invention combines chips with different wavelength ranges in a regular manner and activates corresponding phosphors, thus reducing the proportion of harmful blue light and avoiding the harm of blue light to human eyes. The LED light source of the invention decreases the proportion of harmful blue light while increasing color rendering and catering to the circadian rhythm of human body, and provides a higher quality and healthier lighting environment.
