Audi, as we know, has been at the prow of automotive lighting technology. Indeed, they were the first company to equip their cars with all LED headlamps, dynamic turn indicators and matrix LED headlights. The company has now kicked things up a notch with the Audi R8 LMX.
The R8 LMX is the first production car in the world to have laser spots for its high beams. The combination of LED and laser high beams will be used for the first time on the new Audi R18 e tron Quattro at the 24 Hours of Le Mans on June 14-15. With the new laser high beams, one laser module per headlight generates a cone of light with twice the range of the all LED headlights. Each module comprises four high power laser diodes. With a diameter of just 300 micrometers, these generate a blue laser beam with a wavelength of 450 nanometres.
A phosphor converter transforms this into white light with a colour temperature of 5,500 Kelvin – ideal conditions for the human eye that enable the driver to recognize contrast more easily and help prevent fatigue. The laser spot, which is active at speeds of 60 kph and above, supplements the LED high beam in the Audi R8 LMX and greatly enhances visibility and safety.
An intelligent camera based sensor system detects other road users and actively adjusts the light pattern to exclude them. The car otherwise remains largely the same and continues to be powered by the 5.2 litre, 570 hp, V10 petrol engine. The R8 LMX will go on sale this summer in Germany with a base price of €210,000.
