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.

摘要： A lamp includes a projection lens, a light-emitting element disposed rearwardly of a rear-side focal point of the projection lens to be directed upward, a reflector disposed to cover the light-emitting element from an upper side to reflect light from the light-emitting element toward the projection lens, and a shade disposed with an upper end edge thereof passing closely below the rear-side focal point to block part of reflected light from the reflector. Generally the entirety of a portion of the projection lens positioned above the optical axis is cut away. A reflective surface that reflects downward the reflected light from the main reflector is formed on a rear surface of the shade. A sub reflector that reflects forward the reflected light from the reflector reflected by the reflective surface of the shade so as not to be incident on the projection lens is disposed below the shade.

摘要： A low beam light distribution pattern is formed by turning on a first light source unit and a high beam light distribution pattern is formed by additionally turning on a second light source unit. The second reflector of the second light source unit has reflecting faces of vertical cross-sectional shapes formed by two types of ellipses whose first focal point is on a center of emission of a second light-emitting element and whose second focal points are respectively positioned on points A, B. The additional lens whose rear focal points are on the second focal points A, B is arranged on a circumference of a projection lens. When the second light source unit is turned on, a high beam additional light distribution pattern is formed that vertically strides over the cutoff line of the low beam light distribution pattern.

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： 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 first additional reflector 34 is provided between a light source bulb 22 and a shade 32 and used for reflecting light from a light source 22a to an area in front in the direction of inserting the bulb on the reflective surface 24a of a reflector 24. Further, the area in front in the direction of inserting the bulb on the reflective surface 24a of the reflector 24 is formed as a second additional reflector 36 for reflecting the light reflected from the first additional reflector 34 forward and closer to an optical axis Ax. Thus, direct light from the light source 22a which is to be shielded by the shade 32 is caused to be incident on a projection lens 28 by using the first and second additional reflectors 34 and 36, whereby the direct light can effectively be utilized as forward irradiation light.

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.
