1. A lighting device, comprising:
- a lighting unit emitting a light spectrum having a main peak between 520 nm and 780 nm and a sub peak corresponding to a first wavelength between 400 nm and 470 nm,wherein a second sub peak integral of the light spectrum is greater than a first sub peak integral of the light spectrum,wherein the first sub peak integral is an integral of the light spectrum calculated from a wavelength of the first wavelength minus 20 nm to the first wavelength,wherein the second sub peak integral is an integral of the light spectrum calculated from the first wavelength to a wavelength of the first wavelength plus 20 nm,wherein a ratio of the first sub peak integral to the second sub peak integral is in a range from 20% to 98%.

Abstract
A lighting device includes a first lighting unit and a second lighting unit. The first lighting unit emits a first light spectrum having a main peak between 525 nm and 585 nm and a first sub peak between 400 nm and 470 nm. The second lighting unit emits a second light spectrum having a main peak between 595 nm and 775 nm and a second sub peak between 400 nm and 470 nm. An intensity of the first sub peak is different from an intensity of the second sub peak.
