Even stone can melt, and concentrated sunlight can generate temperatures exceeding a thousand degrees—this is the marvel of the Fresnel lens.

Fresnel lenses are typically made of plastic or glass; one side is highly polished, while the other features a series of tiny, evenly spaced convex lenses that increase in size, creating a helical texture.

The History of Fresnel Lenses

During the era of human seafaring, lighthouses, as iconic structures, have played an indispensable role in guiding humanity’s ongoing exploration of the unknown. Yet the most critical component of a lighthouse is not the tower itself, but the light—more precisely, the lens within the light.

Characteristics and Principles of Fresnel Lenses

Fresnel lenses come in various sizes; the first-order lens, commonly used in lighthouses, is the largest and most powerful, with a diameter exceeding 1.8 meters. Its beam is primarily employed as a coastal light, visible from a distance of 32 kilometers offshore. The sixth-order lens, by contrast, is the smallest, measuring only about 30 centimeters in width, and is used in harbors and navigation channels.

Applications and Practical Significance of Fresnel Lenses in Automotive Lighting

Currently, the development of automotive lighting technology in China has been remarkably rapid. At the same time, driven by the swift advancement of the automotive sector and intense market competition, modern vehicle lighting systems are placing increasingly stringent demands on luminous performance, safety features, and aesthetic appeal. Consequently, the design and fabrication of freeform reflective elements and LED lighting control systems for vehicle lamps have become critically important—representing a departure from conventional optical system design approaches. Non-imaging optical design for automotive lighting control systems is itself a specialized discipline involving iterative design processes. Similar to the traditional integration of parabolic reflectors with light-distribution lenses, the combination of freeform surfaces with Fresnel principles and lens optics can simultaneously achieve both beam convergence and light distribution. This approach not only enables more efficient use of space in rear fog lamp designs but also reduces installation costs. Therefore, this paper analyzes the practical significance of applying Fresnel lenses in the design of LED-based rear fog lamps that leverage Fresnel lens technology.
