With the rapid advancement of light-emitting diodes (LEDs), front fog lamps using LEDs have become a main emphasis for vehicle lighting. For vehicle lighting, the front fog lamps should provide a bar-shaped beam of light with a sharp cutoff at the top and are designed to increase the illumination directed toward ground at a sharp angle. In this study, an innovative lens design based on a freeform surface responding to the requirements of the vehicle lighting is proposed. The design of the two-axis asymmetric freeform lens for LED front fog lamp can meet ECE R19 class F3 regulation without any other lens or reflector.
