US 10,775,011 B2 · Vehicle lamp, vehicle lamp control system, and vehicle provided with vehicle lamp and vehicle lamp control system

Abstract

A vehicle lamp includes a light source unit for road surface drawing capable of forming a light source image longer in an upper and lower direction than a left and right direction of the lamp and a projection lens through which light forming the light source image is transmitted and which projects a predetermined light distribution pattern on a road surface. A light emitting surface or a light transmitting surface of the light source unit is disposed in a vicinity of a rear focal point of the projection lens. The light emitting surface or the light transmitting surface is inclined with respect to an upper and lower direction orthogonal to an optical axis of the projection lens.

A vehicle lamp comprising:

a light source unit for road surface drawing capable of forming a light source image having a non-uniform width;
and
a projection lens through which light forming the light source image is transmitted and which projects a predetermined light distribution pattern on a road surface,
wherein, in the light source image within a focal plane of the projection lens, a region of a part projected on a place distant from the vehicle has a width in a left and right direction of the lamp narrower than a region of a part projected on a vicinity of the vehicle, and
wherein a lower end of a light emitting surface or a lower end of a light transmitting surface of the light source unit is disposed on a rear focal point of the projection lens.
