摘要： There are instances of vehicular lighting in prior art where a significant amount of effectively distributed light radiating from a projection lens is lost. The invention is provided with a semiconductor-type light source (2) and a projection lens (3). The projection lens (3) has an optically active portion (32) transmitting light from the semiconductor-type light source (2), and an optically inactive portion (33). The optically inactive portion (33) of the projection lens (3) is provided with a trimmed portion (33U, 33D) resulting from cutting away a portion of a base shape. As a result, the invention allows the amount of loss in the effectively distributed light radiating from the projection lens (3) to be as small as possible.

摘要： A vehicular lamp includes: a main light source that emits light for forming a predetermined irradiation pattern; an optical member that allows the light emitted from the main light source to travel toward a front side in an irradiation direction to form the irradiation pattern; a heat dissipation member that releases heat from the main light source to outside; and a light guide member that guides light from an auxiliary light source provided as a separate body from the main light source. In the heat dissipation member, the heat dissipation member is provided with an opening part that opens a mounting surface provided with the main light source, and the light guide member guides light from the auxiliary light source toward the mounting surface through the opening part.

摘要： A present invention is equipped with a semiconductor light source, a reflector, and a projection lens. The reflector comprises a first reflective surface and a second reflective surface. The first reflective surface comprises a first focal point and a second focal point positioned near a lens focal point. The second reflective surface comprises a first focal point and a second focal point positioned on a light-emitting surface side relative to the lens focal point. As a result, the present invention provides a high beam light distribution pattern having a hot zone in the center.

摘要： Provided is a vehicular lamp that forms a light distribution pattern for traveling having a lower end portion overlapping an upper end portion of a light distribution pattern for passing and is downsized with a simple configuration. The vehicular lamp includes a projection lens that projects light emitted from a first light source to form the light distribution pattern for passing and projects light emitted from a second light source to form the light distribution pattern for traveling. A lower lens part and an upper lens part are set in the projection lens about a lens axis as a center, a lower focus is set on the lens axis in the lower lens part, and an upper focus shorter in focal length than the lower focus is set on the lens axis in the upper lens part.

摘要： A vehicular lamp includes a first light source that emits light forming a passing light distribution pattern; a second light source that is disposed forward of the first light source and emits light forming a traveling light distribution pattern; a reflector that reflects the light from the first and the second light sources; a first lens that projects the light reflected forward by the reflector; and a second lens that transmits the light from the second light source toward the reflector. The second light source and the first light source are disposed on the same plane. The reflector has first and second reflective surfaces. The first reflective surface reflects the light from the first light source to the first lens. The second reflective surface is disposed forward of the first reflective surface and reflects the light from the second light source through the second lens to the first lens.
