Abstract
A light emitting device includes: a light emitting unit; an optical member configured to transmit or pass light emitted by the light emitting unit, the optical member including: a first region configured to transmit or pass light having a first chromaticity; and a second region configured to transmit or pass light having a second chromaticity different from the first chromaticity; and a movable member configured to move to change a distance between the light emitting unit and the optical member along an optical axis of the light emitting unit.
