Patent ID: 7513654

Claim:
A lighting device for a vehicle, comprising: a light-emitting element disposed on an optical axis extending in a forward and backward direction of the lighting device; a first reflection surface for reflecting light emitted from the light-emitting element in an outer radial direction of the optical axis; and a second reflection surface for reflecting the light emitted from the light-emitting element and reflected by the first reflection surface in the forward direction, wherein a cross-sectional shape of the first reflection surface taken along a first plane including the optical axis is an ellipse, the ellipse having a light-emitting center of the light-emitting element as a first focus and an axis line crossing the optical axis as a major axis, the second reflection surface is disposed between the first focus and a second focus of the ellipse, a cross-sectional shape of the second reflection surface taken along the first plane is a parabola having the second focus of the ellipse as a focus and a point located in the forward direction of the focus as a vertex, and a cross-sectional shape of the second reflection surface taken along a second plane perpendicular to the optical axis is rectangular.
