Abstract
Provided is a surgical light with luminous intensity fine adjustment (LIFA) function, which includes a suspension or support system; one or more light heads carried by the suspension or support system; one or more light sources mounted in the light heads for being operable to supply lighting; one or more driving circuits connected to the light sources for being operable to drive the light sources; one or more operation interfaces connected to the driving circuits to allow for adjustment of the luminous intensities of the light sources between a topmost limit value of luminous intensity and a bottommost limit value of luminous intensity; one or more maximum LIFA activation/deactivation manners allowing the operation interfaces or the driving circuits to enter/exit the maximum/minimum LIFA mode for adjusting and storing the topmost/bottommost limit value of luminous intensity.
