Abstract
A visible light spectrum and light source apparatus are described that provide over 90% of their total radiant power within the 385 nm-530 nm and the 570 nm-820 nm spectral ranges, collectively. The objective of the light spectrum and apparatus is to improve the visibility and shape of a wider range of objects than is practical using conventional LED white light sources at similar radiant power conditions. The new light source can provide good Scotopic or Mesopic at low power levels compared to most other light sources for illumination. One illustrative embodiment of this new spectrum and light source provides a full visible light spectrum with at least 6% of the highest peak radiant power of all wavelengths between 405 nm-730 nm, and another illustrative embodiment provides a similar full spectrum between 440 nm and 730 nm. In both embodiments, the average radiant power in the 475-510 nm cyan spectral region is at least 2-times the average radiant power in the 530-570 nm spectral region.
