Abstract:
A vehicle lighting fixture can achieve uniform projection of light while being capable of providing improved luxurious sense of projected light. The vehicle lighting fixture can include a housing, an outer lens configured to cover an opening of the housing to define a lighting chamber; and a light source and a light guiding lens located in the lighting chamber. The light guiding lens is configured so as to receive light from the light source and guide the light to a light exiting surface thereof for light projection. The light guiding lens has a functional surface which is opposite to the light exiting surface and can include a plurality of flute cuts configured to diffuse light and a plurality of prism cuts configured to reflect light. The plurality of prism cuts are arranged at random on the functional surface.
