Disclosed is a vehicle lamp including: a plurality of light source units, each of which includes a light source that emits a light and a first light guide part that internally guides the light emitted from the light source; and a second light guide part having an outer peripheral surface positioned adjacent to or connected to an outer peripheral surface of the first light guide part. One end surface of the first light guide part in a light guide direction is formed as a light incident surface of the light emitted from the light source, and the second light guide part internally guides and emits the light emitted from the outer peripheral surface of the first light guide part.

Vehicle lamp

A light guide body includes a first rod-like light guide portion and second rod-like light guide portions which are spaced from the first rod-like light guide portion in the vertical direction and plate-like light guide portions which are disposed so as to link their circumferential surfaces. Light that reaches the first rod-like light guide portion via the plate-like light guide portions after being emitted from light sources and entering the second rod-like light guide portions is emitted forward of the lamp from the circumferential surface of the first rod-like light guide portion.

A vehicular rear panel with a new configuration is provided. The vehicular rear panel according to an aspect of the present disclosure is made of a resin material and disposed on a rear vehicle body part. The vehicular rear panel includes a light guiding unit configured to guide light from the light source along an extending direction of the vehicular rear panel and a light emitting unit configured to emit light in the light guiding unit to a rear side of a vehicle.

Vehicular rear panel

A vehicular lamp includes a planar light emitting member having an organic EL light emitting portion at part of a substrate, and a reflecting member and a half mirror that are disposed so as to face each other so that light emitted from the organic EL light emitting portion is reflected repeatedly while allowing part of the light to be transmitted to the front.

Vehicular lamp with OLED having repeated reflections

Disclosed is a vehicular lamp having a light source and a light guide body. In the vehicular lamp, the light guide body is configured by a first and a second rod shaped light guiding portions disposed at positions spaced apart from each other, and a planar light guiding portion disposed to connect the circumferential surface portions of the first and second rod shaped light guiding portions with each other. Further, the light source configured to include a first light source and a second light source disposed to cause light to be incident from an end portion surfaces of the first and the second rod shaped light guiding portions, respectively, and then configured to make each of the first light source and the second light source to emit a different color light with each other.

Vehicular lamp

The present disclosure provides a vehicular lamp including a low-beam lamp and a daytime running lamp. The low-beam lamp includes a low-beam LED, a low-beam reflector, and a projection lens. The daytime running lamp includes a DRL LED, and a DRL reflector. The DRL LED is disposed at the rear side of the low-beam reflector to emit a light in a direction which intersects with the optical axis of the vehicular lamp. The DRL reflector includes an extension area that extends to at least the outer side of the projection lens when viewed from the front, and reflects the light from the DRL LED in the extension area to emit the light to the front side of the lamp through the outer side of the projection lens.

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.

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.

Lamp unit and vehicle lamp

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.

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. &#x3c1;1 is a curvature of the radiation surface in a cross section perpendicular to a direction in which the first extension portion extends, &#x3c1;2 is a curvature of the radiation surface in a cross section perpendicular to a direction in which the second extension portion extends, and &#x3c1;1 is smaller than &#x3c1;2.

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.
