Abstract
An image projection module of a vehicle that includes a light source directed to a projection mask and through it to output optics which is adapted to direct the projected light onto a road near the vehicle. The projection mask is formed on a front wall of a thick lens, whereby this front wall is adapted to direct the projected light from the light source to a flat upper wall of the thick lens which is adapted to totally reflect the projected light onto a curved output wall of the thick lens which is adapted to emit the projected light onto the road into the desired form of the projected pattern. A thick lens for an image projection module of a vehicle.
