摘要： A vehicular lamp (10) includes a light source (14,15); a light guide (16) that guides the light from the light source (14,15); and a reflector (23-28). The light guide (16) includes an incident portion (32,33) to which light from the light source (14,15) is incident, wherein light entering from the incident portion is guided through the light guide (16); and a plurality of reflection portions (17-22) that internally reflect a portion of the guided light toward the reflector (23-28). The reflector (23-28) reflect, in a lamp illumination direction, reflection light that is emitted from the light guide (16) following internal reflection by the plurality of reflection portions (17-22).

摘要： A vehicle lamp (10A, 10B, 10C, 10D) includes a light guide member (20, 120), and at least one light source (31, 33). The light guide member (20, 120) includes a light entrance portion (21a, 23a, 121a, 123a) from which light from the at least one light source (31, 33) enters the light guide member (20, 120), a first light guide (21,121) having first internally reflecting steps (25) configured to internally reflect a first part (L21, L121) of the light, and a first light exit portion (21b, 121b) from which the first part (L21, L121) of the light is output from the first light guide (21, 121), and a second light guide (23, 123) having second internally reflecting steps (26) configured to internally reflect a second part (L23, L123) of the light, and a second light exit portion (23b, 123b) from which the second part (L23, L123) of the light is output from the second light guide (23, 123). The first and second light guides (21, 23, 121, 123) extend such that a gap (22) is provided between the first and second light guides (21, 23, 121, 123). The light guide member (20, 120) is formed as a single unitary piece. The first and second light guides (21, 23, 121, 123) are configured and arranged such that the first light guide (21, 121) does not interfere with the second part (L23, L123) of the light that has been output from the second light exit portion (23b, 123b), and such that the second light guide (23, 123) does not interfere with the first part (L21, L121) of the light that has been output from the first light exit portion (21b, 121b).

摘要： Disclosed is a vehicular lamp with a light guide (20) that extends along a curve (C) which becomes a convexed shape forwardly. A first area of the light guide positioned on an inner peripheral side of the curve (C) is configured by a plane that extends in a direction inclined toward a left end surface side with respect to a second area other than first area. As a result, light which is incident on the light guide (20) from the first area to which light from a LED (30) is emitted is largely refracted forwardly to prevent the light from directly reaching a reflection element (20sA) positioned in the vicinity of the right end surface (20a). In addition, point light is prevented from being generated as the light totally reflected by the reflection element (20sA) is extremely brighter than the light that is totally reflected by another reflection element as in the related art.
