Lighting device for vehicle

摘要

In the present invention, an inner lens of a turn signal lamp is provided with: a lens cut part that inhibits the transmission of light travelling, when seen in a front view, linearly from a substrate toward an outer lens; a projection part that projects toward an LED; and an eave part that extends from the base end side of the projection part inwardly in the vehicle width direction. A harness that is electrically connected with the LED is connected to the substrate through a partial space that is surrounded by the substrate, the projection part, and the eave part.

主权项

1. A vehicular lighting device comprising:
a base, an outer lens attached to a front part of the base, a board having a light emitting diode mounted thereon and which is accommodated inside an inner space formed by the base and the outer lens, and an inner lens arranged between the outer lens and the board, wherein the inner lens comprises:
a front surface,a lens cut region that is disposed on the front surface facing the outer lens and diffuses light from the board toward the outer lens as viewed from the front,a protruding portion disposed on a surface opposite to the lens cut region and at a position facing the light emitting diode and which projects toward the light emitting diode, anda roof having the lens cut region on the front surface and extending from a base end side of the protruding portion along a transverse inward direction of the vehicle; and wherein: a harness, which is electrically connected to the light emitting diode, extends outwardly in the transverse direction passing behind the roof and passing a front of the board and is connected to a front surface of the board; the inner lens is mounted on the base; if an imaginary line is defined that extends in a transverse inward direction of the vehicle through a mounting portion of the base and the inner lens, the inner lens is arranged such that the base end side of the protruding portion is positioned nearer the outer lens in relation to the imaginary line, and an apex side of the protruding portion is positioned nearer the board in relation to the imaginary line; the base includes a flat surface that matches substantially with a direction of extension of the imaginary line; the outer lens and the inner lens are mounted by welding on the flat surface; and wall members are erected on the flat surface between a welded part of the outer lens and a welded part of the inner lens.
