。It consists of a light bulb, an optical system that condenses the light rays emitted from the light bulb, an aperture that allows the main light beam near the optical axis to pass through and blocks excess light flux around it, a convex lens with a small radius of curvature, and a lamp body. In a spotlight, a light bulb and an optical system that condenses the light emitted from the light bulb are placed behind the aperture, and a convex lens with a small radius of curvature is placed in front of the aperture.2 A diffuser plate is placed near the optical axis just in front of the convex lens. A spotlight equipped with a diffuser plate characterized by the arrangement of.
