Summary: | A light source comprising: (a) An LED source comprising at least one LED emitting an LED emission and at least one wavelength-converting material configured to convert a fraction of the LED emission, the LED source emitting a primary SPD; and (b) at least one optical element configured to interact with the primary SPD to remove radiation in the primary SPD, such that a final SPD is emitted from the light source; wherein a fraction of the primary SPD in the wavelength range 430-500 nm is less than 5%; and a fraction of the final SPD in the wavelength range 430-500 nm is less than 1%. |
