Abstract

A lighting apparatus includes a light source unit having a light source portion configured to mount a light source thereon, and a light distribution angle adjusting means coupled to the light source portion and configured to change an irradiation range of the light source. The light distribution angle adjusting means includes a reflector provided with a spiral guide portion in a peripheral surface thereof and configured to reflect a light emitted from the light source, a movable body having an engaging portion configured to slidably engage the guide portion and a control portion configured to limit a direction of a movement to a rotation axis direction of the reflector, a support configured to support a movement of the movable body in the rotation axis direction of the reflector, and an optical component secured to the movable body and configured to change a light path of the light.
