摘要： In a headlamp having a single filament bulb or discharge bulb, there is provided a movable shade that can appear from a reflection mirror located above the single filament bulb. In a usual condition, the movable shade is pulled at the back of the reflection mirror located above the single filament bulb. Then, a light emitted from the single filament bulb is condensed by the reflection mirror and irradiates a very long distance thereby to make a high-speed traveling possible. On the contrary, when it is rainy or foggy, the movable shade is protruded in the front of the reflection mirror. Then, a part of a light emitted from the single filament bulb is shielded by the movable shade, and the road surface in 20-40 m front of the vehicle is darkened thereby to reduce surface reflection from the road surface.

摘要： A vehicle headlamp includes a projection lens which is placed on an optical axis extending in a front and rear direction of a vehicle, a light source which is placed behind a rear focal point of the projection lens, a reflector which reflects light emanated directly from the light source in a forward direction and toward the optical axis, and a light-dark boundary forming plate which is placed between the projection lens and the light source. The light-dark boundary forming plate extends rearward and obliquely downward from a vicinity of the rear focal point of the projection lens, and a light-dark boundary forming portion is formed on a front end portion of the light-dark boundary forming plate. The light-dark boundary forming portion shields a part of the light reflected from the reflector and forms a cut-off line of a light distribution pattern.

摘要： A vehicle head lamp includes: a light source; a reflector that reflects light emitted from the light source; a condenser lens that irradiates the light reflected by the reflector forward; and a shade that blocks part of the light reflected by the reflector to obtain a desired light distribution. The shade includes a main shade that has an opening for passing overhead sign light irradiated forward and upward and a sub-shade that is provided so as to be inclined rearward and downward from an upper edge of the main shade in order to obtain a cut line of the light distribution, and the reflector has an OHS reflection area used to project part of the reflected light toward a lower surface of the sub-shade and that allows the light reflected on the lower surface to pass through the opening of the main shade as the OHS light.

摘要： A current mirror circuit 10 is formed to have a current ratio (a transistor size ratio) of 1:m. As well, respective pairs of nMOS transistors MN1, MN3 and nMOS transistors MN2, MN4 are formed to have a current ratio of 1:m. Two currents output from the current mirror circuit 10 are each distributed to two. The distributed currents flowing in the nMOS transistors MN2, MN4 are added and are then allowed to flow into one resistor R2. Hence, for the resistor R2, only one resistor in which current of double flows suffices when m=1, for example. This effortlessly reduces the necessary resistance to one fourth.
