    • A lighting configuration is disclosed for providing improved vision acuity. The lighting configuration comprises a first light source emitting light having a first wavelength peak in the range from 500 to 530 nm; a second light source emitting light having a second wavelength peak in the range from 600 to 640 nm; and a third light source emitting light having a third wavelength peak in the range from 440 to 460 nm. The radiated power at 55 nm is less than 15% of the radiated power at the wavelength of the second wavelength peak. The light configurations are characterized by an S/P ratio between 2 and 5. Optionally the radiated power at 480 nm is at least 20% of the second wavelength peak. The light sources used in the lighting configuration can be LEDs, preferably LEDs that are substantially free of a color conversion layer.
    • 公开了用于提供改善的视力的照明配置。 照明配置包括发射具有在500至530nm范围内的第一波长峰值的光的第一光源; 第二光源,其发射具有在600至640nm范围内的第二波长峰值的光; 以及第三光源,其发射具有在440至460nm范围内的第三波长峰值的光。 在55nm处的辐射功率小于在第二波长峰值的波长处的辐射功率的15%。 光结构的特征在于2和5之间的S / P比。可选地,480nm处的辐射功率为第二波长峰值的至少20%。 在照明配置中使用的光源可以是LED,优选地是基本上没有颜色转换层的LED。
