Abstract: Disclosed is a vehicular lamp with a light guide that extends along a curve which becomes a convexed shape forwardly. A first area of the light guide positioned on an inner peripheral side of the curve 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 from the first area to which light from an LED is emitted is largely refracted forwardly to prevent the light from directly reaching a reflection element positioned in the vicinity of the right end surface. In addition, point light is prevented from being generated as the light totally reflected by the reflection element is extremely brighter than the light that is totally reflected by another reflection element as in the related art.

Abstract: A vehicle lighting equipment is provided with: a light source in which a light emitting diode is employed; and a transparent lens on which a light emitted from the light source is incident and from which the incident light is emergent. The transparent lens includes: a center portion positioned to oppose the light source; and a light guiding portion positioned on an outer peripheral side of the center portion to guide the incident light to an inward area.

Abstract: A vehicular lamp includes a lamp outer case formed by a cover and a lamp housing; a light source disposed inside the lamp outer case; and a light guide that guides light emitted from the light source, wherein the light guide is shaped as a column. The light guide includes a first extension portion that extends on a horizontal plane side, and a second extension portion that extends on a vertical plane side with respect to a reference line that extends in a direction inclined 45 degrees with respect to the horizontal plane. An outer surface of the light guide includes an incident surface to which light emitted from the light source is incident, an internal reflection surface that internally reflects light incident from the incident surface, and a radiation surface that is formed as an outward-convexly curved surface and radiates at least light reflected by the internal reflection surface.

Abstract: A vehicular lamp includes a light source; a light guide that guides the light from the light source; and a reflector. The light guide includes an incident portion to which light from the light source is incident, wherein light entering from the incident portion is guided through the light guide; and a plurality of reflection portions that internally reflect a portion of the guided light toward the reflector. The reflector reflects, in a lamp illumination direction, reflection light that is emitted from the light guide following internal reflection by the plurality of reflection portions.

Abstract: A lamp unit includes at least one light source that emits light in a predetermined direction, and a light guide body including at least one incident surface where light emitted from the light source enters, a first emission surface that emits light entering from the incident surface in a horizontal direction, and a plurality of second emission surfaces that emits light entering the incident surface in a horizontal direction and emits light entering the incident surface to the upper side of the horizontal direction. The second emission surfaces are formed above the first emission surface at different positions in an up-down direction, and are positioned on the back side of the first emission surface so as to be spaced apart from one another in the horizontal direction.

Abstract: A vehicle lighting equipment is provided with: a light source in which a light emitting diode is employed; and a transparent lens on which a light emitted from the light source is incident and from which the incident light is emergent. The transparent lens includes: a center portion positioned to oppose to the light source; and a light guiding portion positioned on an outer peripheral side of the center portion to guide the incident light to an inward area. The center portion includes an incident surface which opposes to the light source and on which the light emitted from the light source is incident, and a first emergent surface from which the light that is incident from the incident surface is emergent. The light guiding portion includes a second emergent surface from which the light guided to the inward area is emergent.
