Patent ID: 8007154

Claim:
A vehicle lamp configured to emit light in a light emitting direction along a principal optical axis, the vehicle lamp comprising: a light source; a reflector having a parabolic reflective surface configured to reflect light beams, emitted from the light source, into generally parallel reflected light beams; and a lens formed in a generally rectangular shape and having a center and a plurality of lens cut portions configured to diffuse the generally parallel light beams coming from the parabolic reflective surface of the reflector, wherein the principal optical axis of the vehicle lamp is configured to intersect with the center of the lens, the lens includes a plurality of ridge lines or valley lines extending generally radially from the principal optical axis of the vehicle lamp and dividing the generally rectangular lens into at least a first lens cut portion, a second lens cut portion, a third lens cut portion, and a fourth lens cut portion serving as the lens cut portions, the first lens cut portion is located below a horizontal plane containing the principal optical axis of the vehicle lamp, the first lens cut portion being a substantial mirror image of the second lens cut portion located above the horizontal plane, the third lens cut portion is located to the left of a vertical plane containing the principal optical axis of the vehicle lamp, the third lens cut portion being a substantial mirror image of the fourth lens cut portion located to the right of the vertical plane, and the vehicle lamp is configured such that the generally parallel light beams coming from the parabolic reflective surface of the reflector are diffused at least in the left and right directions through the first lens cut portion and the second lens cut portion, and at the same time, the generally parallel light beams coming from the parabolic reflective surface of the reflector are diffused at least in the up and down directions through the third lens cut portion and the fourth lens cut portion.
