Optimizing Automotive LED Lighting

Software eases the burden of complex design while producing thinner, more efficient and less expensive optics.

Michael W. Zollers, Optical Research Associates

Headlights and taillights have been on automobiles for about as long as automobiles have had rubber tires, and filament lamps have provided their light for just about as long. The size and shape of the filament have kept the optical designs of these lamps relatively unchanged, with breakthroughs occurring primarily in the materials used to make the reflectors and the lenses. The next big change, however, is a move away from the filament and toward LEDs in all automotive lighting. LED lamps have been on vehicles for about a decade, and most of today’s designs use scaled-down versions of the...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
