Figure 1A: Relative power output of a white LED (<span Pn(λ) Pn(λ) Pn(λ) Ρn (λ) ), and the eye photopic sensitivity curve V (λ). A phosphor on the LED is used to convert the blue LED to white, but much of the power is outside the eye’s sensitivity range.
This article details a method to convert LED lumen ratings into spectral photon flux, enabling precise control of illumination for high-speed machine vision applications.
