Abstract
A light guide body has a first light guide part disposed in front of a light source, a second light guide part extending from a front surface side of the first light guide part toward at least one lateral side of the first light guide part, a plurality of third light guide parts branching and extending from a midway portion of the second light guide part, an incidence part located on a back surface side of the first light guide part, and a first emission part located on a tip side of the plurality of third light guide parts, the second light guide part has a shape in which a cross-sectional area gradually decreases toward the tip side, and the plurality of third light guide parts are arranged next to each other in an extension direction of the second light guide part.
Claims12
A vehicle lamp comprising:
- a light source;
- and
- a light guide body configured to guide light emitted from the light source,
- wherein the light guide body has:
- a first light guide part disposed in front of the light source;
- a second light guide part extending from a front surface side of the first light guide part toward at least one lateral side of the first light guide part;
- a plurality of third light guide parts branching and extending from a midway portion of the second light guide part;
- an incidence part located on a back surface side of the first light guide part and configured to cause the light emitted from the light source to enter an inside of the first light guide part;
- and
- a first emission part located on a tip side of the third light guide part and configured to emit the light guided inside the third light guide part to an outside of the third light guide part,
- the second light guide part has a shape in which a cross-sectional area gradually reduces toward the tip side, and
- the plurality of third light guide parts are arranged next to each other in an extension direction of the second light guide part, wherein the plurality of third light guide parts have a shape in which each of inclined angles of the plurality of third light guide parts with respect to an axial direction of the second light guide part gradually reduces as it gets closer to the tip side of the second light guide parts.
A vehicle lamp comprising:
- a light source;
- and
- a light guide body configured to guide light emitted from the light source,
- wherein the light guide body has:
- a first light guide part disposed in front of the light source;
- a second light guide part extending from a front surface side of the first light guide part toward at least one lateral side of the first light guide part;
- a plurality of third light guide parts branching and extending from a midway portion of the second light guide part;
- an incidence part located on a back surface side of the first light guide part and configured to cause the light emitted from the light source to enter an inside of the first light guide part;
- and
- a first emission part located on a tip side of the third light guide part and configured to emit the light guided inside the third light guide part to an outside of the third light guide part,
- the second light guide part has a shape in which a cross-sectional area gradually reduces toward the tip side, and
- the plurality of third light guide parts are arranged next to each other in an extension direction of the second light guide part, wherein
- the plurality of third light guide parts constitute the first emission parts having a same shape with each other in a state in which the plurality of third light guide parts extend in a same direction from positions of the second light guide parts other than a front surface side of the second light guide parts and in which each of the tips of the plurality of third light guide parts are facing the front surface side.
