Abstract
A lighting unit () for a medical luminaire () has a number of groups of LEDs (″) that are connected to a common planar printed circuit board (). Each LED (') of at least one of the groups (′) is associated with a respective optic (′) by which a respective LED-optic pair (′) is formed. The respective optics, based on the structure (), specify a tilt angle () of a central light beam axis (′) of an emitted light beam of the LED optics pair in a tilt direction () of the respective LED optics pair. The tilt direction is defined such that the respective light beam axes of the emitted light beams of the LED optics pairs from the at least one group of LEDs are at least partially skewed in pairs with respect to one another.
