摘要： Due to an effect of a solenoid of a moving mechanism, when a valve and a shutter are positioned at a first position, a light source is positioned at a first light source position and a shutter is in a state of closing a window. A lighting luminous flux from a light source is reflected by a reflector so as to be irradiated as a first light distribution pattern. Thus, a part of the lighting luminous flux is introduced to the reflector from the open window. Therefore, it is possible to effectively utilize the lighting luminous flux emitted from one valve in correspondence to a light distribution pattern.

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 moveable shade. The front end of the shade body of the movable shade is formed into a substantially semispherical shape. The maximum radius of the pivotal locus of the shade body is smaller than conventional shades that have a front end portion formed into a cylindrical shape. Further, a slot is found in the front end portion that extends along the pivotal face of the movable shade. Therefore, the shade body and the discharge bulb do not interfere with each other even when the movable shade is caused to pivot, and the maximum radius of the pivotal locus of the shade body is further reduced. Thus, the shade body of a fixed shade can be smaller in size so that a greater space can be secured for use in disposing the fixed shade within an allowable range that refrains from unnecessarily shading the light reflected from a reflector.

摘要： A headlamp in which a right elliptic reflecting surface and a left elliptic reflecting surface are provided on a position toward an upper front portion of the bulb, a right parabolic reflecting surface is provided on a position toward a right lower portion of said main reflecting surface, and a left parabolic reflecting surface is provided on a position toward a left lower portion of said main reflecting surface, whereby waste light can be recovered and used as irradiating light. A headlamp in which the elliptic reflecting surfaces which capture light emitted upwardly and forwardly from the bulb and parabolic reflecting surfaces which reflect said light in a desired direction are provided. A light-distribution varying means is provided in the optical path of the parabolic reflecting surfaces, whereby it becomes possible to switch between light distributions.

摘要： A vehicle light can include a single light source and be capable of switching between low-beam mode and high-beam mode by moving a movable portion. The vehicle light can also include a first reflecting surface, a projection lens, and a shutter selectively insertable in the luminous flux from the first reflecting surface to the projection lens. The vehicle light can further include a second reflecting surface having a first focus and a second focus, a third reflecting surface having a first focus and second focus, a fourth reflecting surface having a focus approximately on the second focus of the second reflecting surface, wherein when the third reflecting surface is located in its inserted position relative to luminous flux between the second reflecting surface and the fourth reflecting surface, the first focus of the third reflecting surface is substantially on the second focus of the second reflecting surface. The movable portion can include the shutter and the third reflecting surface.

摘要： A vehicle lamp unit is disclosed that utilizes a high intensity discharge bulb for high beam, low beam and fog/driving lamps. The lamp uses reflectors and shields to selectively block light emitted from the HID bulb and to direct the light into a desired pattern. A control device is utilized to move the shields into various desired light blocking positions. Lamps of various shapes can be fabricated using the shield system by using optics to direct light into diverse preferred patterns.
