Abstract: Described herein are surgical lights comprising: a plurality of light generating units, each light generating unit comprising: at least one first light emitter that emits light having a first spectrum, at least one second light emitter that emits light having a second spectrum, and at least one optical element configured to mix the light from the at least one first and second light emitters such that the light generating unit emits light that is a mixture of the first and second spectrums; and a controller configured to adjust relative intensities of the at least one first light emitter and the at least one second light emitter to adjust a spectrum of light generated by the plurality of light generating units.

Abstract: A surgical light for illuminating a target with light that has a reduced contribution of a portion of the visible spectrum includes a first light source configured to emit light having a first spectrum; a second light source configured to emit light having a second spectrum that does not include the portion of the visible spectrum; and a controller configured to simultaneously activate the first and second light sources for illuminating the target with light that has a reduced contribution of light in the portion of the visible spectrum relative to white light.

Abstract: In a method for controlling a surgical light, the luminance distribution is determined spatially selectively in a measured field and the illuminated field size is adapted to the size of the surgical field while taking account of the luminance distribution.

Abstract: A surgical light has a plurality of LEDs and a main reflector which directs the light of the LEDs onto an operating field. The main reflector is made in areal form and is divided into a plurality of reflector zones.
