Abstract
A light-emitting module including: a first light source including a first light-emitting element and a wavelength converter and emitting visible light having a chromaticity within rectangle range ABCD, the wavelength converter changing a wavelength of a portion of light emitted by the first light-emitting element; and a second light source including a second light-emitting element and emitting red light. The light-emitting module emits white light by mixing the visible light and the red light, and satisfies conditions 2.0≦(S−S)/(F−F)≦3.0 and 0.01≦((x−x)+(y−y))≦0.02.
