摘要： A light source bulb 22 is inserted and fixed into a reflector 24 from a side in a position placed downward apart from an optical axis Ax. Thus, it is possible to effectively utilize an optical-axis side region in a reflecting plane 24a for a light distribution control. Moreover, an almost prism-shaped light transmitting member 30 is provided in the vicinity of the upper end of the outer peripheral edge portion of a projection lens 28 between the projection lens 28 and the reflector 24, and a direct light from a light source 22a toward the upper space of the projection lens 28 is emitted forward to be deflected downward.Consequently, it is possible to increase the amount of a light to be irradiated on the forward part of a vehicle, and furthermore, to carry out a deflection control for the direct light emitted from the light source 22a with high precision.

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 vehicle headlamp including a headlamp unit and an auxiliary lamp in which the brightness of an end portion of the low beam light distribution pattern formed by the beam irradiation from the headlamp unit is reinforced by the auxiliary light distribution pattern formed by the beam irradiation from the auxiliary lamp unit. The high luminous intensity area of the auxiliary light distribution pattern partly overlaps the high luminous intensity area of the low beam light distribution pattern, thus allowing the low beam light distribution pattern and the auxiliary light distribution pattern to be combined. Further, by way of controlling the beam irradiation intensity of the auxiliary lamp unit by a light control unit, the brightness of the low beam light distribution pattern is reinforced by the auxiliary light distribution pattern that has brightness in response to the vehicle running condition.

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.
