Automotive Industry Fully Embraces LEDs

Audi with LED headlights

The automotive industry has embraced LED lighting.  LED headlights caused a sensation when Audi put full LED headlights in the A8 in 2008.  Since then, the automotive market has been drawn to LEDs for not only forward exterior illumination, but also brake lights and interior lighting including dashboard illumination, instrument clusters, and entertainment system controls.

LEDs have become part of the color scheme of the car interior and a significant part of how each manufacturer brands its cars.  LED-based lighting is in many 2012 cars such as BMWs, Infinities, Lexus, Toyotas, Fords, Chevys and even the Rolls Royce.  Audi even featured LED headlights in their 2012 Super Bowl commercial about vampires (they died as the headlights caught them around a campfire).

The main drivers for auto manufacturers are power efficiency and the way that LEDs work with a car’s electrical system that helps save fuel. For example, LED headlights are four times as efficient as halogen lamps and require the vehicle’s alternator to replenish less energy, saving fuel.  These benefits are good for the environment.  According to Audi, cars equipped with LED headlights accounted for a reduction of 25,000 tons of CO2 emissions in the first year of sales.

About Beth

It seems like LEDs are in everything these days – backlighting everything from your mobile phone, Apple iPad and flat screen HDTV to traffic lights, light bulbs and even the kitchen sink. But, making LEDs is a complex process that begins with the creation of sapphire. Not the pretty blue gemstone, but large commercial crystals that can weigh as much as 400 lbs. Once these large sapphire crystals are grown into boules and cooled, they’re cut into cores, cut further into flat circular wafers, polished and then used to grow LEDs. About 85 percent of HB-LEDs (high brightness) are grown on sapphire. There’s not that much information out there about the process. This blog is meant to shed some light (excuse the pun) on sapphire, LEDs and the industry that is devoted to making our lives just a little brighter. In the months ahead, we’ll tackle some topics that will help you understand a little more about sapphire and LED industry. Here’s a sample of what we’ll cover in the coming months: • Growing sapphire • For a wafer, size matters • Quality - When sapphire wafers go bad • LED light bulbs • Market & myths • Interviews with industry shining stars • Reports from industry events • Current events in perspective Please join us each week to learn more about sapphire and the LED market. We look forward to seeing you.
