    摘要： A vehicle light (1) comprising a single light source (2a) capable of switching its light distribution pattern between a low-beam mode and a high-beam mode by a movable portion (7, 17), a first reflecting surface (3) whose longitudinal direction is along an optical axis X of the vehicle light (1), and having a first focus (f1) in the vicinity of the light source (2a), for reflecting light rays from the light source (2a) to the forward, a projection lens (9), and a shutter (6) for providing a predetermined shape to the light rays from the first reflecting surface (3) on formation of the low-beam mode light distribution pattern by being selectively inserted in the luminous flux from the first reflecting surface (3) to the projection lens (9): further comprising a second reflecting surface (4) of an ellipse group reflecting surface having its first focus (f1) approximately on the light source (2a) and its second focus (f4) at a predetermined position; at least one third reflecting surface (5, 5a, 5b) having a first focus (f5) in a predetermined position and at least one second focus (f5a, f5b) in at least one predetermined position; a fourth reflecting surface (8) having a focus (f8) approximately on the second focus (f4) of the second reflecting surface (4) for reflecting light rays to a predetermined forward direction; wherein when the third reflecting surface (5, 5a, 5b) is located in its inserted position relative to the luminous flux from the second reflecting surface (4) to the fourth reflecting surface (8), the first focus (f5) of the at least one third reflecting surface (5a, 5b) is substantially on the second focus (f4) of the second reflecting surface (4); and wherein the movable portion (7) comprises the shutter (6) and the at least one third reflecting surface (5, 5a, 5b).

    摘要： A headlamp assembly (10) for producing high and low beam patterns includes a housing (12) having a reflector (18). The reflector (18) includes high (22) and low (20) beam reflector surfaces. A light source (24) is disposed within the housing (12) for producing light rays projecting towards the high and low beam reflector surfaces. A plurality of shafts (26) extends alongside the light source. A drive (74) is operatively connected to the plurality of shafts for rotation thereof. A shield (64) is connected to the plurality of shafts (26). Activation of the drive (74) rotates the plurality of shafts (26) to selectively move the shield (64) between an open position, in which the light rays project towards and reflect off of the high beam reflector surfaces to produce the high beam pattern, and a closed position, in which the light rays project towards and reflect off of the low beam reflector surfaces to produce the low beam pattern while the shield blocks a portion of the light rays from projecting towards the high beam reflector surfaces.

    摘要： A head lamp (1) for a vehicle wherein an actuator (4) is made to be able to be moved to a leveling actuation range (A) corresponding to output from a vehicle body sensor and to a beam change position B out of a leveling actuation range when a beam changing switch is set to a drive beam position, and if the actuator (4) is moved to the beam change position B at least a part (5b) covering a lower half of a discharge lamp (2) of the hood (5) is moved back to switch it from a passing beam state to a drive beam state. The actuator (4) for leveling actuation indispensable to be provided for the head lamp for a vehicle having the discharge lamp (2) as a light source, makes it possible also to switch between the passing beam state and drive beam state, thereby dissolving problems of large size and high cost of the head lamp.
