  • Method and system for maximizing the output of surgical lights
    Patent number: 11153953
    Abstract: Adjustment of a surgical light is provided to optimize viewing an object. First, a distance between the surgical light and the object being viewed can be measured and the light output from the surgical light can be adjusted depending on the distance. Second, the surgical light can be moved to optimize the direction of light emitted from the surgical light according to the position of light from visible locating light sources. Third, the light emitted from a pair of light assemblies can be adjusted to ensure that the intensity of the light at an area of overlap of the light assemblies stays below a predetermined level to help prevent eye fatigue and dehydration and excessive radiation of a wound at the area of overlap.
