Abstract

An optical system for lighting according to an embodiment includes: a laser light source configured to emit first light having a peak wavelength in a range of 420 nm to 480 nm; a wavelength conversion member including a phosphor layer including two or more types of phosphor particles, part of the first light being incident on the wavelength conversion member, from which second light exits; and a reflective-transmissive member configured to transmit part of the first light and reflect part of the second light as third light, in which a transmittance of the reflective-transmissive member is less than 85% for light having a wavelength of 450 nm, and is 20% or less for light having a wavelength of 550 nm.
