20110267832 | VEHICLE LIGHT - A vehicle light can maintain its maximum light intensity in its light distribution pattern while improving the brightness sense at a farther area. The vehicle light can be provided in a front portion of a vehicle body, for forming a road surface light distribution pattern on a road surface in front of the vehicle body. The road surface can include at least a farther area, an intermediate area, and a nearby area. The road surface light distribution pattern can include a plurality of light source images each extending in a horizontal direction, the respective light source images being projected to the corresponding farther area, intermediate area and nearby area, respectively, without striding across the adjacent areas. The vehicle light can include an LED light source having a rectangular light emission surface with a short side of 0.6 to 0.8 mm, and an optical system configured to project the plurality of light source images each extending in the horizontal direction to the corresponding farther area, intermediate area and nearby area, respectively, without striding across the adjacent areas, thereby optimizing the road surface illuminance in each of the farther area, intermediate area and nearby area. | 11-03-2011 |
20130003401 | VEHICLE LIGHTING UNIT - A vehicle lighting unit can be configured to allow the brightnesses of light observed through vertically arranged lenses to substantially match when the lenses are viewed from a certain viewpoint in front of the vehicle. The vehicle lighting unit can include: a first lens on a first upper optical axis; a second lens on a second lower optical axis; a semiconductor light-emitting device; a first revolved ellipsoidal reflector; a shade; a second revolved ellipsoidal reflector; and a third reflector. The third reflector is inclined at an inclination angle with respect to the horizontal plane adjusted such that light emitted from the semiconductor light-emitting device, reflected by the second reflector, focused at a second focal point of the second reflector, reflected by the third reflector, and passing through the second lens is directed in a direction at a predetermined upward angle with respect to the horizontal plane. | 01-03-2013 |
20130083553 | VEHICLE LIGHTING UNIT - A vehicle lighting unit can include a first lens and a second lens disposed below the first lens, and a first semiconductor light-emitting device disposed substantially at a vehicle rear-side focal point of the first lens. Light emitted from the first semiconductor light-emitting device in a narrow angle direction can be incident on the first lens. A first reflector can be disposed diagonally forward and downward with respect to the first semiconductor light-emitting device such that light emitted from the first semiconductor light-emitting device in a wide angle direction is incident thereon and reflected diagonally rearward and downward. The light emitted in the narrow angle direction and incident on the first lens having a luminous intensity higher than the light emitted in the wide angle direction. A second reflector can be disposed diagonally rearward and downward with respect to the first reflector. | 04-04-2013 |
20130188380 | VEHICLE LIGHTING UNIT - A vehicle lighting unit is capable of improving the design freedom (such as that for forming a high-beam light distribution pattern) and to allow an observer to visually recognize the employed projection lens even when including a plurality of lens portions (including a plurality of rear-side focal points) as a single lens with high aesthetic feature. | 07-25-2013 |
20130250600 | VEHICLE LIGHTING UNIT - A vehicle lighting unit can be capable of illuminating pedestrians and the like present in lateral areas above a horizontal line while suppressing generation of glare to oncoming or preceding vehicles. A vehicle lighting unit can also be capable of forming both a basic light distribution pattern and an overhead light distribution pattern without invading an area for reflecting light for forming a basic light distribution pattern. The vehicle lighting unit can include a projector lens disposed on an optical axis, a light source disposed behind a rear-side focal point of the projector lens, a reflecting surface configured to reflect light emitted from the light source so that the light is directed toward the optical axis, and a shade disposed between the projector lens and the light source. The shade can be configured to shield part of light emitted from the light source and reflected by the reflecting surface. | 09-26-2013 |
20140036526 | VEHICLE LIGHTING UNIT - A vehicle lighting unit can include a daytime running lamp (DRL) function and a light emission unit that can be miniaturized. The vehicle lighting unit can include a headlamp (HL) unit having a HL light guiding lens and a DRL unit. The HL light guiding lens can include a light incident surface in front of a light source LED for HL, a front reflection surface, a rear reflection surface, and a light-transmitting section. The front reflection surface can internally reflect light from the light incident surface obliquely rearward and downward. The rear reflection surface can internally reflect the light from the front reflection surface. The light-transmitting section is disposed between the front and rear reflection surfaces in terms of its vertical direction. The DRL unit can be disposed behind the light-transmitting section, so that light from the DRL unit can pass through the light-transmitting section and projected forward. | 02-06-2014 |
20140069079 | GAS TURBINE COMBUSTOR - A gas turbine combustor includes a burner disposed upstream of the combustion chamber for supplying a gas and air to an interior of the combustion chamber to hold a flame provided with a first swirler in which a gas hole and an air hole are alternately formed in a circumferential direction. A first gas is supplied to the gas hole in the first swirler and air is supplied to the air hole. A swiveling flow path is formed in the gas hole and the air hole in the burner to swivel the gas and the air and supply the gas and the air to the interior of the combustion chamber, a second gas hole is formed in the swiveling flow path in at least one of the air hole and the gas hole, and a second gas is supplied through the second gas hole. | 03-13-2014 |
20140233253 | VEHICLE HEADLIGHT - A vehicle headlight utilizes a rotationally asymmetric projection lens with its light emitting surface inclined with respect to the optical axis thereof, whereby the light emitted from the light source and projected forward through the light emitting surface of the projection lens is diffused substantially uniformly with respect to the optical axis of the projection lens, for example, uniform substantially in the right and left directions and/or the upper and lower directions. This can be achieved by designing the reflecting surface to have its optical axis inclined with respect to the optical axis of the projection lens by a predetermined angle so that light emitted from the light source and projected forward through the light emitting surface of the projection lens is made uniform with respect to the optical axis of the projection lens (for example, uniform substantially in the right and left directions and/or the upper and lower directions). | 08-21-2014 |
