摘要： A lamp includes a projection lens, a reflector, and a prismatic lens. The prismatic lens receives direct light, which has been transmitted from the light source outwardly with respect to a widthwise direction of a vehicle, and refracts the received light toward the optical axis. The prismatic lens is separated outwardly from the optical axis in the widthwise direction of a vehicle and is provided between the projection lens and the reflector. The prismatic lens can provide an additional light distribution pattern formed outside, in the widthwise orientation, of a basic light distribution pattern formed from light passed though the projection lens.

摘要： Between a projection lens and a reflector and outwardly separated from an optical axis in the widthwise orientation of a vehicle, a prismatic lens refracts the light from a light source toward the outside of the widthwise direction of the vehicle, close to the optical axis. From light having exited from the prismatic lens, an additional light distribution pattern is formed outside, in the widthwise orientation, of a basic light distribution pattern formed from light passed through the projection lens. An additional reflector for reflecting the direct light that traveled from the light source toward the inside of the widthwise orientation, toward the prismatic lens is inwardly separated from the optical axis in the widthwise direction of the vehicle between the projection lens and the reflector. As a result, a second additional light distribution pattern is formed outside of the additional light distribution pattern in the widthwise orientation.

摘要： When the vehicle body rolls to the oncoming lane, a light source bulb is turned to a direction opposite to a rolling direction to keep the posture of the light source bulb in an erect state. Accordingly, a horizontal cut-off line CL1 of a low-beam light distribution pattern P is prevented from slanting downward to the oncoming lane side. A horizontal cut-off line forming area 20a1 of a reflector 20 is formed with a plurality of reflection elements 20s1a and 20s1b and the like. Those elements are formed extending from the upper end to the lower end and slanting, at an angle of 5°, downward to the optical axis Ax1 with respect to the vertical direction. As a result, when the vehicle body rolls to the oncoming lane side, the reflection elements 20s1a and 20s1b and the like are substantially orthogonal to a light-dark borderline L1 formed by an inner shade 18c of the light source bulb, to thereby sharpen the horizontal cut-off line.

摘要： A headlamp for a vehicle has a projection lens, a light source disposed behind a rear focal point of the projection lens and having an optical axis extending in a longitudinal direction, a reflector which reflects light from the light source toward the projection lens, and a rotary shade which is rotatable and shields a part of the light which is projected from the light source and reflected by the reflector. The rotary shade has a plurality of pattern forming sections, each of which respectively forms a corresponding light distribution pattern including an upper part irradiation pattern and a lower part irradiation pattern. A center of the lower part irradiating patterns is located lower than a horizontal line. A center of the upper part irradiating patterns is located above the horizontal line. The pattern forming sections form at least four different upper part irradiating patterns.

摘要： A lamp unit of a vehicular headlamp includes a projection lens with an optical axis; a light source formed from a semiconductor light-emitting element; a first reflector that reflects light from the light source so as to condense such light on or near the optical axis; and a shade positioned between the light source and the projection lens so as to extend along the optical axis direction. The shade shields part of the light reflected by the first reflector. In the lamp unit of the vehicular headlamp, a shielding surface extends rearward from a front end of the shade, where the shade is positioned near a rearward focal point Rf of the projection lens. The shielding surfaces serve as a second reflector that reflects light from the first reflector toward the projection lens. In addition, a transparent portion is formed on part of the second reflector such that part of the light reflected by the first reflector passes downward of the rearward focal point of the projection lens and is then incident to the projection lens.

摘要： A projection-type vehicular headlamp structure that is capable of forming at least two types of light distribution in at least two modes, and is also capable of controlling the radiated light thereof with high precision in addition to keeping to a minimum any noticeable difference when switching between modes. A portion of a reflector is structured as a mobile reflection portion which may separate from a remaining reflective portion. An additional reflector is disposed generally behind the mobile reflective portion. The additional reflector is incident to light from a light source when the mobile reflective portion is separated from the remaining reflective portion. Light incident from the mobile reflective portion, the remaining reflective portion, and the additional reflector is reflected forward to a projection lens of the vehicular headlamp, providing illumination in the area preceding a vehicle's traveling path.
