Abstract
Illuminating sections of a light guide with LEDs leads to unwanted light bleeding to other parts of the light guide. Furthermore typically LEDs are placed at a large distance from the area that couples out light from this LED due to a spike in intensity close to the LED. In order to avoid this spike being visible in the lit area the distance is increased which results in unwanted areal increase of the overall system. The present provides a layout to overcome these challenges.
