Abstract
A projection headlight includes a reflecting mirror, a light shield, a reflector, a lens and a light emitting unit. The reflecting mirror includes a first reflective surface unit. The light shield is disposed in the reflecting mirror and includes a second reflective surface unit facing rearwardly. The reflector is disposed behind the light shield and includes a third reflective surface unit facing forwardly. The light emitting unit is disposed behind the light shield, and emits a light beam reflected by the first reflective surface unit toward the second reflective surface unit, and then reflected by the second reflective surface unit toward the third reflective surface unit to be projected forwardly through the lens.
