16.4. LED-Based Glare-Free system designs

Multibeam

LED technology is the latest evolution for Glare-Free High Beam projectors.

When compared to Halogen and Xenon, LEDs offer many benefits, including:

l Luminous efficacy (in lumens per watt).

Multibeam module

l Lifespan that exceeds that of the vehicle itself.

l Flexibility in terms of optical design and style: several LEDs produce the beam, and each one can be coupled with particular optical systems. LED systems can replace and even exceed Xenon headlamp performance. In order to illustrate the features of different LED systems, five different concepts are taken in a single scenario: the test car is approached by a vehicle on the left lane 80 m ahead, which is just out of the low beams’ reach.

Depending on the position of a horizontally rotating internal shield with different cut-off forms, the lamp has alternatively low beam, motorway beam, high beam, GFHB (L-shaped) and a flat beam with a linear cut-off. One or more additional modules can be added to the main module to boost the quantity of light projected in low beam or high beam. (Ford applications: S-Max, Galaxy) In Glare-Free High Beam mode, the whole beam rotates around a vertical axis according to the position of detected vehicles. Similar to Xenon lights, Multi Beam is compact and offers a precise lateral positioning of the vertical cut-offs.
