摘要： As the annular translucent member, an annular lens formed from a peripheral edge portion of a convex-meniscus lens is disposed between a projection lens and a reflector along an outer peripheral edge of the projection lens. Direct light from a light source toward a space beyond the outer periphery of the projection lens is caused to illuminate forward of the lamp by the annular lens, thereby effectively utilizing light source luminous flux. In relation to the above, a shape of a back surface of the annular lens is formed into a spherical surface having its center at a luminescence center of the light source. Accordingly, direct light from the light source can travel straight without being deflected by a back surface of the annular lens, whereby a light deflection angle on a front surface of the annular lens can be calculated easily and with good accuracy.

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.

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： An bending lamp is provided with, within a lamp room composed of a lamp body and a cover, a light source bulb equipped with a light source for emitting light; a reflector for reflecting light emitted from said light source; and a projection lens for directly forward projecting the light emitted from said light source. The reflector projects the light emitted from the light source directly outward of the vehicle. The optical axis of the group of light rays directly projected through the projection lens and the optical axis of the group of light rays projected through the reflector are oriented in independent directions.

摘要： A reflector includes a first reflector portion located above the central axis of a headlamp extending in the longitudinal direction of a vehicle, and a second reflector portion located below the central axis. A first light source and a second light source are arranged such that: the light emitted from the first light source is reflected by the first reflector portion to form a first light distribution pattern; and the light emitted from the second light source forms two partial light distribution patterns by being reflected with both the first reflector portion and the second reflector portion, and a second light distribution pattern, which is different from the first light distribution pattern, is formed by combining the two partial light distribution patterns.
