Abstract: A laser optical system for headlamps may include a laser diode generating a laser beam, a fluorescent body reacting to the laser beam and outputting white light, a main reflector reflecting the white light output from the fluorescent body forward, an aspheric lens directing the white light reflected by the main reflector forward, and a beam lens provided on a front surface of the fluorescent body. The beam lens may contract the laser beam entering the fluorescent body and reduce a radiation angle of the white light output from the fluorescent body. The laser diode may be configured such that a center axis of the laser diode is aligned with a reference line, the reference line being substantially perpendicular to an incident surface of the fluorescent body and passing through a center or a center portion of the fluorescent body.

Abstract: A double reflecting structure may include a first reflecting portion reflecting light that may be emitted from a light source, and a second reflecting portion formed on one side of the first reflecting portion to reflect again the light that may be reflected by the first reflecting portion.

Abstract: A side-illuminating projection lens and a headlight having the same, in which a side-illuminating lamp is implemented with a projection lamp that illuminates to the side of a vehicle by radiating light in the radial direction, wherein sideways-radiated light is projected in the radial direction and is thus smoothly combined with forward-radiated light, thereby improving the driver's vision.
