VEHICLE LAMP

摘要

A vehicle lamp includes a light source mounted on a vehicle body and a light guide body for guiding light generated by the light source. On the light guide body, vertically to a light travelling direction, a plurality of notch-shaped portions are formed in line. The notch-shaped portions become narrow in pitch as the distance from the light source increases and are formed deeper as the distance from the light source increases. Preferably, the notch-shaped portions exhibit arc cross-sections having the same curvature radius, and the depths of the notch-shaped portions are specified by the central angles of the arc cross-sections.

1. A vehicle lamp including a light source mounted on a vehicle body, and a light guide member for guiding light emitted by the light source,
wherein the light guide member has a row of a plurality of recess-shaped portions formed therein substantially perpendicularly to a traveling direction of the light emitted by the light source, the recess-shaped portions are formed such that, as distances from the light source of individual ones of the recess-shaped portions increase, pitches between the recess-shaped portions decrease and depths of the recess-shaped portions increase, and each of the recess-shaped portions is shaped such that two arcuate back surfaces are opposed to each other.
