摘要： The deflection angles of the irradiation of lamps provided at the left and right portions of an automobile are continuously increased in correspondence to the increase of a steering angle until the steering angle reaches a predetermined value. The left and right lamps are held at particular deflection angles respectively when the steering angle is equal to or more than a predetermined steering angle. The value of the particular deflection angle of the lamp on the steering direction side is made larger than that of the lamp on the opposite side. When the deflection angle is small, the left and right lamps are deflected in almost the same state to irradiate the straight traveling direction or the traveling direction of an automobile. When the deflection angle becomes large, the lamp on the steering direction side irradiates the traveling direction and the lamp on the opposite direction irradiates an area in the straight traveling direction.

摘要： A first shade 32 is properly moved to vertically shift the position of a cutoff line, and furthermore, a lighting unit 20 is properly tilted in a vertical direction to displace a whole light distribution pattern in the vertical direction. Consequently, a light irradiation is carried out with a light distribution pattern at an irradiation angle corresponding to a vehicle traveling situation. In that case, a second shade 34 is properly moved to form a dark portion in a central part on the lower end of the light distribution pattern in a predetermined size if necessary. Consequently, the amount of a light irradiation on a short-distance region can be controlled finely, and a road surface on this side can be prevented from becoming too bright in a high-speed travel and a light reflected by the road surface which causes a glare can be prevented from being generated in a rain travel.

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： 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.
