To provide a quiet projector capable of being used for either of spot illumination and downward omnidirectional illumination.

The projector includes a light source lamp formed of an LED, a reflector for light, and an angle adjusting member for the light source lamp. The angle adjusting member can adjust positions for light of the light source lamp from the position wherein the light vertically turns upward to the position wherein the light slantly turns downward. The reflector is located at an upper part of the light source lamp, and has a conical or pyramid-shaped reflecting surface wherein its tip turns downward. The downward omnidirectional illumination can be attained since the light of the light source lamp is reflected by the reflector when the light of the light source lamp is turned upward, and the spot illumination can be attained when the light of the light source lamp is slantly turned downward.
