Abstract
The present invention provides a surgical lamp for illuminating a surgical site. The surgical lamp includes a housing that defines an internal cavity. A light source is disposed within the internal cavity of the housing for producing a light field at a surgical site that is remote from the housing. A voltage sensitive device is disposed between the light source and the surgical site. The voltage sensitive device has light transmissive properties that change in response to a biasing voltage applied thereto. Control means control the biasing voltage to the voltage sensitive device.
