Abstract

An illumination device includes a light source; a light condensing element for concentrating light from the light source onto a light concentration position; a plate for receiving light from the light condensing element and transmitting such light; a phosphor element for receiving light from the light source at the light concentration position; and a lens for projecting light from the plate. The plate is configured to rotate about an axis perpendicular to an optical axis of the lens to shift the light concentration position, which is between the plate and the lens, in a direction perpendicular to the optical axis of the lens.
