A projector type lighting unit can include a projection lens having an optical axis, a rear-side focal point positioned on the optical axis, an incident surface, and an exiting surface. A light source can be disposed on or near the focal position of the projection lens, and an image of the light source can be projected through the projection lens. A light path adjusting unit can be configured to diffuse part of the image of the light source in an upward direction when the lighting unit is installed in a vehicle light. The light path adjusting unit can be disposed in between the projection lens and the rear-side focal point of the projection lens, and can be a reflector having a planar mirror inclined with respect to a plane perpendicular to the optical axis of the projection lens toward the projection lens by about 45 degrees.
