Abstract

See full text

To improve the brightness of irradiated light in the lighting apparatus using a liquid crystal element. A lighting apparatus includes: a light source; a condensing unit that condenses light emitted from the light source so that it forms a focal point at a predetermined position; a liquid crystal element arranged corresponding to the position of the focal point; a first polarizing element disposed on a light incident surface of the liquid crystal element; a second polarizing element disposed on a light emitting surface of the liquid crystal element; and a projection lens that magnifies and projects images generated by the liquid crystal element and the first and second polarizing element; where the liquid crystal element is arranged at a tilt such that the light incident surface and the light emitting surface form a predetermined angle that is non-orthogonal and non-parallel to the optical axis of the projection lens.
