    摘要： In first to third support wires (12,13,14) connected to a low beam filament (L) and a high beam filament (H), which are arranged in the light source bulb (9), a bent portion (13a) is formed by bending the second support wire (13) from a curved portion (13c) towards the first support wire at an obtuse angle (θ2), and each rear lead (Lb,Hb) of the low beam filament (L) and the high beam filament (H) is connected to said bent portion (13a).
    Moreover, a bent portion (14a) is provided by bending the third support wire (14) from a curved portion (14c) towards the second support wire at an obtuse angle (θ3), and a front lead (Ha) of the high beam filament (H) is connected to the bent portion (14a).
    The extended portions (13b,14b) of the second support wire (13) and the third support wire (14) are inclined at an obtuse angle (θ4,θ5), respectively.

    摘要： A vehicle headlamp (1) is provided with: a fixed reflector (3) having reflecting surfaces made of parabola-based free curved faces; movable reflectors (13U) having reflecting surfaces made of parabola-based free curved faces; and semiconductor-type light sources having light emitting chips (4) shaped like a planar rectangle. When the movable reflectors (13U) are positioned in a first location, a light distribution pattern for low beam is obtained. When the movable reflectors (13U) are positioned in a second location, light distribution patterns for high beams are obtained. When the movable reflectors (13U) are positioned in a third location, light distribution patterns for daytime running light are obtained. As a result, the vehicle headlamp (1) can achieve downsizing, weight reduction, power saving, and cost reduction.
