Abstract (en)
A vehicle pixelated lighting device, a vehicle lamp, and a vehicle. The vehicle pixelated lighting device comprises a pixel lighting light source (10), a light-transmitting element (30) and a lens assembly (20). The pixel lighting light source (10) is provided with an integral light-emitting surface (11). The light-transmitting element (30) is arranged at the edge of the pixel lighting light source (10) and covers at least a part of the edge of the integral light-emitting surface (11) of the pixel lighting light source (10). The light-transmitting element (30) is used to change the deflection angle of a light ray emitted from the pixel lighting light source (10) into the light-transmitting element (30), and to emit a polarization light ray to the lens assembly (20). The intersection of the reverse extension line of the polarization light ray and the plane of the integral light-emitting surface (11) is located outside of the light-emitting point of an incident light corresponding to the polarization light ray. The part of light entering the light-transmitting element (30) is directed at a point away from the outside of a pixelated light shape center point by means of the light-transmitting element (30), thereby achieving blurring of an pixelated light-shape edge, such that the pixelated light shape has a soft transition at the blurring edge thereof, and finally, after the pixelated light shape and the non-pixelated light shape are superposed, the transition is uniform at the superposition edge, and the connectivity is good..
