摘要:
A vehicle lamp unit includes a reflective surface based on an ellipse; a semiconductor light source of which a light emitting portion is provided at a first focal point of the reflective surface or a vicinity of the first focal point; and a projection lens that projects a reflected light that is a light emitted from the semiconductor light source and reflected by the reflective surface to outside. An emission direction of a maximum light emission intensity from among light intensities of the semiconductor light source is inclined in a direction opposite to the projection lens with respect to an optical axis of the projection lens.

A vehicle lighting apparatus emits a spot light distribution pattern to be combined with a low-beam light distribution pattern emitted from a headlamp. The vehicle lighting apparatus includes a semiconductor light source formed with a rectangular light emitting element; and a lens that projects light from the rectangular light emitting element under an upper horizontal cutoff line of the low-beam light distribution pattern, as the spot light distribution pattern of a substantially rectangular shape.

The low beam filament and the high beam filament are disposed in such a positional relationship as the virtual image of the irradiated portion of the high beam filament does not produce glaring light in the low beam light distribution pattern. As a result, it is made possible to effectively utilize near 100% of light incident on the reflecting surface of a reflector and to obtain good low beam light distribution pattern and high beam light distribution pattern.

A vehicle headlamp that is capable of optically distributing a spot portion of a light distribution pattern having a cutoff line to a cruising lane side is provided. The present invention includes semiconductor-type light sources 2L and 2R and lenses 3L and 3R. On emission surfaces 31L and 31R of the lenses 3L and 3R, peak portions 32L and 32R that form a spot portion SP of a light distribution pattern for low beam LP are respectively provided in given locations that are close to a cruising lane side with respect to optical axes ZL and ZR of the lenses 3L and 3R. As a result, the present invention can provide the vehicle headlamp that is capable of optically distributing the spot portion SP of the light distribution pattern for low beam LP having a cutoff line CL.

A vehicle headlamp is provided with: a main reflector having a convergent reflecting surface; a semiconductor-type light source; a projecting lens; an auxiliary reflector having a parabolic reflecting surface; a shade and a light shading member that are structured integrally with each other; and a switching device. By means of the switching device, the shade and light shading member, which are structured integrally with each other, are switched and positioned in a first location and a second location, thereby allowing light distribution patterns for high and low beams to be switched and illuminated toward a forward direction of a vehicle. As a result, the vehicle headlamp becomes capable of achieving downsizing, weight reduction, power saving, and cost reduction.

A digital lighting apparatus for a vehicle, which employs a reflection digital light deflector, includes a storage unit that stores digital data of a plurality of light distribution patterns and a controller. The controller selects digital data corresponding to a predetermined light distribution pattern from among the digital data stored in the storage unit and controls the reflection digital light deflector, and illuminates a road surface and the like with the predetermined light distribution pattern.

A solid-liquid separator and a process for washing the same wherein SS (sended solids) caught in space portions of a filter medium in a tank are caused to flow out from the space portions and be suspended while at least part of the filter medium is maintained in a fluidized state by air washing, and rapid drainage through a lower portion of the tank causes the SS in the suspended state to be rapidly removed without being again caught into the space portions of the filter medium.
