An illumination apparatus having scanning laser source and a vehicle headlight using the illumination apparatus includes a light source, a wavelength converting member and a mirror mounted on a movable frame unit configured to rotate the mirror about two orthogonal axes. Light emitted by the light source is reflected by the mirror such that rotation of the mirror by the movable frame unit scans the reflected light in two directions at a substantially right angle with respect to each other and/or direct the reflected light towards the wavelength converting member to provide various color lights. The movable frame unit might be actuated by an AC voltage having a low frequency.
