Abstract:
1. A vehicle light for a vehicle having a driver, the vehicle light comprising: a first light source; a second light source; a first optical system configured to direct light emitted from the first light source to a first area corresponding to a central vision of a driver in front of the vehicle; and a second optical system configured to direct light emitted from the second light source to a second area corresponding to a peripheral vision of the driver, wherein the first light source and the second light source are configured to be simultaneously turned on to emit light through the respective first and second optical systems so as to project light forward, and the first light source has an S/P ratio, which is represented by (S(λ)*V′(λ))/(S(λ)*V(λ)) in which S(λ) is a spectrum of the first light source, V′(λ) is a relative luminosity factor in scotopic vision, and V(λ) is a relative luminosity factor in photopic vision, lower than an S/P ratio of the second light source.
