型の前照灯。 A projector in which a light source bulb is installed near the focal point of a reflecting mirror, the light emitted from the light source bulb is reflected by the reflecting mirror and focused near a shade having a cut line, and the reflected light is projected forward by a convex lens. In this type of headlamp, a shade is installed above the focal point to block part of the upper half of the luminous flux passing near the focal point, and is directed 4°C below the horizontal direction of the luminous flux projected in front of the convex lens. A projector-type headlight that is characterized by dimming nearby light.
