Abstract
A lighting apparatus includes an LED chip that emits primary light, and phosphor particles that emit secondary light by being excited with the primary light. The lighting apparatus emits light including the primary light and the secondary light. The light has an emission spectrum having a first peak in a wavelength ranging from 420 nm to 460 nm, a second peak in the wavelength ranging from 530 nm to 580 nm, a third peak in the wavelength ranging from 605 nm to 655 nm, a first trough in the wavelength ranging from 440 nm to 480 nm, and a second trough in the wavelength ranging from 555 nm to 605 nm.
