摘要： Disclosed is a vehicular headlamp including: a basic lamp unit configured to form a main light distribution pattern that is controlled in light distribution so as to satisfy illuminance requirements at a plurality of predetermined sites in a low beam light distribution pattern which is projected on a vertical virtual screen positioned in front of a vehicle; and a plurality of additional lamp units controlled in light distribution so as to irradiate light to any one of left and right diffusion regions adjacent to the main light distribution pattern. The low beam light distribution pattern is formed on the vertical virtual screen by combining the basic lamp unit and the plurality of additional lamp units.

摘要： A lamp includes a substrate, a heat-dissipation member, an optical member, and a heat-transfer member. The optical member, the substrate and the heat-dissipation member are arranged in this order. In two members of the heat-dissipation member and the optical member or two members of the heat-dissipation member and the substrate, one end sides thereof are fixed to each other by a fixing mechanism, and the other end sides thereof are hooked and fixed such that the two members are prevented from being displaced in a direction away from each other with the heat-transfer member located between the one end side and the other end side being a support point and the one end side being a force point.

摘要： A vehicle lamp includes a first light source, a first reflector which reflects light emitted from the first light source to form a low beam light distribution pattern, a second light source, a second reflector which reflects light emitted from the second light source to form a high beam additional light distribution pattern and includes a short distance reflection surface provided at a closer position and a long distance reflection surface provided at a farther position with respect to the second light source at a predetermined interval therebetween, a third light source, and a third reflector which is arranged at the back side of the second reflector and reflects light emitted from the third light source through a gap between the short distance reflection surface and the long distance reflection surface. The third light source is configured to be lit in a low beam irradiation mode.

摘要： A vehicle lamp includes a projection lens, a first light emitting chip and a second light emitting chip disposed on left and right sides, and a reflector which reflects light toward the projection lens. The reflector includes a reflecting surface which includes a left rear area, a right rear area, a left front area, and a right front area. The left rear area and the right front area reflect light emitted from the first light emitting chip to converge to a rear focal point of the projection lens at a higher convergence degree than light emitted from the second light emitting chip. The right rear area and the left front area reflect light emitted from the second light emitting chip to converge to the rear focal point of the projection lens at a higher convergence degree than light emitted from the first light emitting chip.

摘要： A lamp unit has a first light source, a second light source which is illuminated when the first light source is turned off, and a projection lens having a first entering surface which is associated with a first focal point and a second entering surface which is associated with a second focal point. Light emitted from the first light source is incident on the first entering surface and passes through the projection lens. The second light source is disposed between the first light source and the projection lens in a position through which light emitted from the first light source to reach the first entering surface does not pass. Light emitted from the second light source is incident on the second entering surface and passes through the projection lens.

摘要： A vehicle lamp 10 includes a first parabolic high-beam condensing reflector 16b, a second parabolic high-beam condensing reflector 17c and a parabolic high-beam diffusing reflector 16a. The first and second parabolic high-beam condensing reflectors 16b, 16c forms a high-beam condensed light distribution pattern by reflecting light emitted from light sources 18b, 18c. The high-beam diffusing reflector 16a forms a high-beam diffused light distribution pattern by reflecting light emitted from a light source 18a. A part 21 of a reflection surface of the high-beam diffusing reflector 16a is located in front of front end portions of the first and second parabolic condensing reflectors 16b, 16c.
