Abstract
A vehicle light can include a light emitting diode (LED) serving as a light source and an optical system for controlling a light distribution pattern of the light beams from the LED light source utilizing a light guide (such as a lens body having an inner reflecting surface). The vehicle light can project illumination light with a low beam light distribution pattern. The vehicle light can include an LED light source and a lens body serving as a light guide. The lens body can include a light incident surface, a reflecting surface, and a light exiting surface. The LED light source can have a rearmost end light emitting point from which light beams are emitted to form a bright-dark boundary line. Among the light beams, perpendicularly incident light beams not subjected to refraction can be projected toward the bright-dark boundary line while obliquely incident light beams that are subjected to refraction can be corrected to be directed in a lower angular direction than the bright-dark boundary line and to be mixed with the other light beams, thereby preventing color shading of illumination light from the vehicle light.
