Abstract

A vehicle lamp includes a long solid-core shaped light guide; a first light source that irradiates an end portion of the long solid-core shaped light guide in a longitudinal direction such that light is radiated long from an end side of the vehicle lamp toward another end side of the vehicle lamp; and a second light source that irradiates the another end side of the vehicle lamp to a lateral outer side.

Claims (45)

1. A turn lamp incorporated into a door mirror, the turn lamp comprising:

a base housing housed inside a body of the door mirror and supporting a first light source and a second light source;

an inner housing formed to be curved in a laterally long direction and incorporated from outside of the body so as to be opposite to the base housing;

a curved and laterally long solid-core shaped light guide formed at a base housing opposing side of the inner housing;

a pair of upper and lower flanges extending vertically from upper and lower edges of the light guide;

an inner lens body integrally formed as a one-piece unitary structure with a lateral outer end side of the light guide and the flanges;

the first light source disposed inside a lateral inner end side of the light guide, the first light source irradiates the light guide from the lateral inner end side toward the lateral outer end side;

the second light source disposed outside the lateral outer end side of the light guide, the second light source irradiates the inner lens body toward a lateral outer side of the inner lens body;

a substrate electrically connected to the first light source and the second light source and positioned between the light guide and the base housing that is opposite to the light guide; and

a lens part that covers the light guide and the inner lens body, wherein:

the irradiation of the first light source extends to the inner lens body from the lateral inner end side of the light guide through the lateral outer end side of the light guide,

the second light source is positioned to irradiate toward the lateral outer side of the inner lens body across the inner lens body and the lens part,

the second light source includes a plurality of light sources that are spaced from each other in a lateral direction to each other,

an outer light of the plurality of light sources included in the second light source is positioned such that a radiation direction of the outer light has an angle with respect to a radiation direction of an inner light of the plurality of light sources included in the second light source when the outer light and the inner light are operating,

both the outer light and the inner light are positioned such that both the outer light and the inner light irradiate toward the lateral outer side of the inner lens body when both the outer light and the inner light are operating, and the outer light and the inner light are spaced in the lateral direction from each other,

the substrate is supported integrally at an inner side of the light guide by latching claws formed on a projecting tip end portion of a basal portion projecting from the inner housing toward a side of the base housing, and

the pair of upper and lower flanges function as light isolators.

2. The turn lamp according to claim 1 , wherein:

the first light source irradiates the light guide in a longitudinal direction at the lateral inner end side of the light guide where the lens body is not formed.

3. The turn lamp according to claim 1 , wherein the plurality of light sources included in the second light source are positioned at different angles.

4. A turn lamp comprising:

a base housing supporting a first light source and a second light source;

an inner housing formed to be curved in a laterally long direction and incorporated so as to be opposite to the base housing, the inner housing includes:

a curved and columnar light guide formed at a base housing opposing side of the inner housing,

a pair of upper and lower flanges extending vertically from upper and lower edges of the light guide, and

an inner lens body integrally formed as a one-piece unitary structure with a lateral outer end side of the light guide and the flanges;

the first light source disposed inside a lateral inner end side of the light guide, the first light source irradiates the light guide from the lateral inner end side toward the lateral outer end side;

the second light source disposed outside the lateral outer end side of the light guide, the second light source irradiates the inner lens body toward a lateral outer side of the inner lens body;

a substrate electrically connected to the first light source and the second light source and positioned between the light guide and the base housing that is opposite to the light guide; and

a lens part that covers the light guide and the inner lens body, wherein:

the irradiation of the first light source extends to the inner lens body from the lateral inner end side of the light guide through the lateral outer end side of the light guide,

the second light source is positioned to irradiate toward the lateral outer side of the inner lens body across the inner lens body and the lens part,

the second light source includes a plurality of light sources that are spaced from each other in a lateral direction to each other,

an outer light of the plurality of light sources included in the second light source is positioned such that a radiation direction of the outer light has an angle with respect to a radiation direction of an inner light of the plurality of light sources included in the second light source when the outer light and the inner light are operating,

both the outer light and the inner light are positioned such that both the outer light and the inner light irradiate toward the lateral outer side of the inner lens body when both the outer light and the inner light are operating, and the outer light and the inner light are spaced in the lateral direction from each other,

the substrate is integrally supported by latching claws formed on a projecting tip end portion of a basal portion projecting from the inner housing toward a side of the base housing, and

the pair of upper and lower flanges function as light isolators.

5. The turn lamp according to claim 4 , wherein the plurality of light sources included in the second light source are positioned at different angles with respect to the inner lens body.

6. The turn lamp according to claim 4 ,

wherein the inner housing is incorporated into a recess of the base housing.

7. A door mirror comprising:

a body; and

the turn lamp according to claim 4 incorporated into the body.

8. The turn lamp according to claim 1 , wherein the flanges are formed from a translucent resin material.

9. The turn lamp according to claim 4 , wherein the flanges are formed from a translucent resin material.
