  • Patent number: 9719650
    Abstract: A vehicle lamp includes a shade movable between a light blocking position and a light blocking release position. A light emitting surface of a light emitting element faces one side in a lateral direction and an upper end edge of the light emitting surface extends in a front-rear direction. A reflective surface of a reflector includes a first reflective area and a second reflective area. A low-beam light distribution pattern having a horizontal cut-off line and an oblique cut-off line is formed by a reflected light beam from the first reflective area when the shade is at the light blocking position, and a high-beam light distribution pattern is formed by the reflected light beams from the first reflective area and the second reflective area when the shade is at the light blocking release position.

  • Patent number: 6994454
    Abstract: A vehicular cornering lamp which radiates beams having different light distribution patterns in accordance with different driving conditions such as different driving speed ranges. A bulb shade blocks light from a front filament from reaching a lower reflecting area on a reflecting surface of the reflector of the lamp while allowing light from the front filament to strike only an upper reflecting area, while an upward light blocking shade provided above and adjacent the light source bulb blocks light from the rear filament from reaching the upper reflecting area while allowing light from the rear filament to strike only the lower reflecting area. The active area of the reflecting surface of the reflector can be changed by switching illumination between the front filament and the rear filament.

  • Patent number: 6824301
    Abstract: A vehicular headlamp which provides a low-beam light distribution pattern having a horizontal cut-off line and an oblique cut-off line and which enhances distant visibility in the traveling line by assuring a sufficient amount of light in a hot zone, even if the height of a reflector is small. The reflecting surface of the reflector is configured to have first reflecting zones which reflect light so as to form a horizontal cut-off line, and second reflecting zones which reflect light so as to form an oblique cut-off line. The second reflecting zones Z2 are provided at two positions on right and left sides of the lamp optical axis Ax which are arranged diagonally with respect to the lamp optical axis Ax. The amount of light in a hot zone HZ is increased by superimposing light distribution patterns produced by the light reflected from each of the second reflecting zones.

  • Patent number: 6821004
    Abstract: A lighting unit for a low beam is provided with a movable shade constituted to take a shielding position in which a part of light incident on a reflector from a light source is shielded and a shielding release position in which the shielding is released. When a vehicle speed exceeds a predetermined set vehicle speed, or when a vehicle turns toward the opposite lane side, the movable shade is moved to the shielding release position, thereby adding auxiliary light distribution patterns P(B) and P(C) having cutoff lines CLb and CLc above cutoff lines CL1 and CL2 of a low beam distribution pattern P(L) to the low beam distribution pattern P(L) to carry out beam irradiation. Thus, the visibility of a distant road is enhanced.

  • Patent number: 6644828
    Abstract: A vehicular headlamp includes a bulb with two filaments disposed one behind the other, a bulb internal shade provided in the vicinity of the front filament, and a reflector for reflecting light produced by the filaments. The reflector includes an upper part and a lower part. A bulb external shade is provided outside the bulb. The bulb internal shade prevents light produced by the front filament from entering into the lower reflector part, and the bulb external shade prevents light produced by the rear filament from entering into the upper reflector part.

  • Patent number: 6402355
    Abstract: A vehicular headlamp for low-beam illumination with a light distribution pattern having a horizontal cutoff line and a diagonal cutoff line so as to improve long distance visibility on the road on which the vehicle is traveling. An upward deflecting reflecting element for irradiating a beam onto a space in an area above a diagonal cutoff line is formed at the outer peripheral edge of the diagonal cutoff line forming area on a reflecting surface of a reflector. As a result, a small light distribution pattern P1 exhibiting high luminous intensity is formed in a space in the area above the diagonal cutoff line.
