摘要： Exemplary embodiments of the present invention include a light source unit in which lowering of an illumination intensity of an emitted luminous flux is reduced or prevented. A light source lamp unit includes a light source lamp having a light emitting section in which discharging emission is performed between electrodes, an elliptic reflector to emit a luminous flux radiated from the light source lamp in a certain uniform direction, and a secondary reflecting mirror provided on the opposite side of the light source lamp opposite from the elliptic reflector. A center of light emission C2 between the electrodes does not match a first focal point F1 of the elliptic reflector, a center of the source of reflected light C1 of the secondary reflecting mirror does not match the first focal point F1 of the elliptic reflector. The center of light emission C2, the first focal point F1, and the center of the source of reflected light C1 are disposed on a straight line perpendicular to a straight line connecting the first focal point F1 and a second focal point F2 of the elliptic reflector.
