1. A vehicle lamp configured to be installed on a side lower part of an outer part of a vehicle, the vehicle lamp being configured to project image light of visible light onto the ground on a lateral side of the vehicle, the vehicle lamp comprising:
a housing;
an optical system housed in the housing, the optical system being configured to generate image light of visible light; and
a window disposed in a partial area of a wall face of the housing, the window including a transparent plate having a planar outer surface, the transparent plate being configured to transmit the generated image light and emit the generated image light to an external space of the housing,
wherein
the optical system includes a lens group configured to generate the image light, an optical path bending mirror configured to bend an optical path of the generated image light, and a concave mirror configured to reflect the image light with the optical path bent and emit the image light to the external space from the window, and
a positional relationship between the window and the concave mirror is set in such a manner that, in a state in which the vehicle lamp is installed on the side lower part of the outer part of the vehicle in a position that enables the vehicle lamp to project the image light emitted from the window toward the ground on the lateral side of the vehicle, at least a part of the concave mirror in the height direction is positioned higher than the whole of the window in the height direction, and more than half or the whole of the window in the height direction is positioned lower than the concave mirror;
wherein the window and the concave mirror are positioned on a same side of the housing, and
a portion of the wall face, which extends vertically above the partial area of the wall face in which the window is disposed, is non-transparent; and
wherein the housing includes an emitting-side end face facing rearward or forward of the vehicle, a side face facing sideward of the vehicle, and the partial area of the wall face including a corner face located between the emitting-side end face and the side face, the corner face facing diagonally sideward and rearward or diagonally sideward and forward of the vehicle, and the window is disposed on the corner face.
