ABSTRACT:
A light emitting device that is capable of changing the illumination angle in the transverse direction while efficiently utilizing energy from a light source. An emission unit includes at least an arc tube. A pair of reflecting means are arranged in a longitudinal direction of the arc tube so as to reflect luminous fluxes emitted from the arc tube in a direction which varies according to the distance between the emission unit and each of the reflecting means.
