2018 Chevy Traverse Gets Magna's Next-Gen LED Headlights

Magna International Inc. has developed an integrated light-emitting-diode headlight system that will debut this year on General Motors Co.’s 2018 Chevrolet Traverse crossover vehicle.

Dubbed D-Optic, the system combines multiple high-power LEDs with precise, injection-molded lenses. The next-generation design improves lighting performance, energy efficiency and design flexibility, according to the supplier.

The D-Optic lens consists of a single component, whereas a conventional headlamp optical system is made from a number of parts that require precision geometry and location. A high-temperature acrylic is used in the D-Optic lens, which Magna says enables molding with the clarity required for a high-efficiency optical headlamp.

The new lens is closely coupled (300 microns apart) with an LED to help optimize the balance between performance and efficiency. Magna notes the design also eliminates the need for active cooling.

D-Optic lenses come in four prescriptions that allow carmakers to tailor lamp performance. The scalable design allows LEDs and lenses to be added or subtracted to conform to vehicle specification.

LED lights consume 60% less energy than halogen bulbs and 40% than high-intensity discharge lights, Magna notes. The company developed and manufactures the D-Optic system at its new 140,000-sq-ft facility in Plymouth, Mich.
