The headlights on the new Mercedes Benz CLS are equipped with Oslon Compact light-emitting diodes from Osram Opto Semiconductors. These extremely compact high-power LEDs can be arranged very close together in the headlight so that adaptive front lighting systems can be achieved. To achieve ideal distribution of light with the Osram LEDs the car manufacturer uses a camera mounted on the windshield to cover the area in front of the vehicle. Four controllers in the vehicle perform calculations 100 times per second to determine the best lighting for the driver. LED-based adaptive lighting systems enable the road ahead to be automatically illuminated with exceptionally bright light and with precisely controlled distribution without dazzling other road users.
Each module in the headlight is equipped with 24 Oslon Compact light-emitting diodes. Thanks to UX:3 chip technology the LEDs achieve high luminous efficacy even at high currents. With package dimensions of 1.6 mm x 1.2 mm they are extremely compact so they can be arranged close to one another in the headlight with a high degree of flexibility. These light-emitting diodes therefore provide the basis for both AFS and light guide solutions.
