Provided is a lamp configured to control an irradiation angle. The lamp includes a light emitting unit that is provided with an LED and a reflector having a reflecting surface that reflects light from the LED. The reflecting surface of the reflector is formed to have a parabolic shape in a cross-section perpendicular to an optical axis of the LED. The reflecting surface of the reflector is formed to have an elliptical shape in a cross-section parallel to the optical axis of the LED so as to condense and diffuse reflected light beams in a forward direction.
